HDMI Output to 720p - Google Chromecast

Hi @all,
I've a problem with Chromecast. My setup is that I'm using an Onkyo receiver which has plenty of HDMI slots. Since I've no TV I've connected a monitor to the Onkyo. Unfortunately the monitor works at best in 720p (I've also attached a PS3 to the system where I'm also using 720p)...
So my question is, can I force Chromecast to output its HDMI signal in 720p. I don't have any image at the moment, with the exception during booting... (I see the Chrome Logo).
Any ideas????

720p is the highest and I believe the default that chromecast outputs at. You can change to 720p high or low bitrate, or 480p via the chrome browser extension.Sorry I was thinking about tab casting when I read the OP.

That's false. That setting is only for the resolution of the tab-casting. Not the output of the Chromecast. Chromecast outputs a 1080p signal. (https://play.google.com/store/devices/details?id=chromecast). I beleive it even upscales lower resolution content to 1080 but I can't confirm on my current setup.

Thank you so far.... yes, it is about the signal what's coming out of the chromecast not about casting! I definitely need 720p and I hope somebody can tell me how to force this device to do this.... Normally you could do this on any device (PCs, PS3, Xbox, Ouya...).
I'm really open to any advice.

Hi, I'm wondering if you found any answer to forcing(?) chromecast to a certain resolution. I'm wondering if the chipset inside the stick is capable of outputting anything other than 1080P? In my case I have to have 480P or 1080i (my TV is too old that it doesn't even accept 720P <LOL>). I know the Roku3 won't output anything lower than 720P so I'm wondering what the chip inside chromecast is capable & if there are ways to turn the switches on/off?

I'm still searching for a solution... none found yet.
What I figured out is that Chromecast can detect what the device can display at maximum. There is a standard to this...
But in my case (the AV receiver which accepts full resolution but the display not) I can't force it to do this... I submitted a feature request at Google help... I also read that people claim Google are very much interested in getting feedback... so I did what I can do.
So for now my Chromecast is just an Audio Stream adapter... but a quite good one so net completely useless for me

Thank you for the heads-up and I'm glad you are getting use out of it
Been looking around and found some info on the variant of SoC that is in the stick (from Marvell) as that thread suggested the info on Marvell site is thin and nothing about resolution. I sent an inquiry to their sales support but since I'm not looking to buy a lot of 10k of those SoC on the pallet so I'm not holding my breath for an answer. Also the thread said that it is not quite the same SoC so they were suspecting a neutered on customized for Google.

I have a similar problem, as I'm trying to run my Chromecast on a non-TV.
Short of Google giving options (which would be GREAT - most HDMI sources allow selecting what resolution gets sent), you could use an in-line EDID "injector" like Gefen HDMI Detective. They also have a DVI version of it called DVI Detective.
EDIT: Another option may be the Dr HDMI
In your case I would set the HDMI Detective to report that it only supports 480P and 720P resolutions and put it after your receiver (between receiver and monitor), so all your devices see proper progressive-only EDID.
Alternatively you could try to see if you can reprogram your monitor's EDID (via something like Powerstrip), though that's significantly more dangerous especially if you're a novice.

The Gefen is $129 and the Dr. HDMI is $399!
He'd be better off buying a new Monitor.

Dr. HDMI is only $99 (full boat HDfury3 is $399, Dr. HDMI is down past). But I agree, if money is to be thrown at the problem it's poetically better spent on a new monitor, unless you have something special.

OK, thanks for the correction. I clicked the buy now button and it showed up as $399, and I thought somethings wrong here.
OP, What monitor do you have? Does it not show any picture or is the picture quality just not good?
I recently did a search for best TV under $500 and their are some decent options for the money. My parents just picked up a 32" LCD TV from Costco on clearance for $180. It a Sceptre and 720p, but looks good and can handle a 1080p feed. It was on clearence, so might be hard to find at that price, but you can get a decent TV on the cheap with a little legwork.
Good luck.

FWIW as a test I have my Chromecast running to a Planar 1024x768 VGA monitor through a HDfury2.
The Planar says it's getting a 1280x720 signal, and I can tell from the green tint that it's receiving YPbPr (aka YUV).
So Chromecast definitely can output 720p if it thinks that's all the monitor can accept.
and I meant "probably" not "poetically" heh

any news?? I have a 720p projector connected to the onkyo. The chromecast doesn´t appear...

If you wall power Chromecast and boot it directly connected to the projector with the projector on, do you get picture?

When the screen says "starting...." I can see the picture well, I guess its on 720p, then it appears chromecast logo blurry and then a red noise digital noise screen.
I guess I need to change chromecast output resolution...

IIRC the boot screen is 480p.
This could be a failure of resolution negotiation (projector tells Chromecast it supports a resolution it can't handle) or missing/broken HDCP support on the projector.
Unfortunately you can't force Chromecast to a specific resolution so you'd have to control the reported supported resolutions with Dr. HDMI or similar that I mentioned earlier in the thread.
Is the digital noise blocky or more like fine random colored pixels?
-= this post enhanced with bonus mobile typos =-

The digital noise are red vertical lines at the screen, if I press the home button on my onkyo remote it changes to the casted image in 4 squares disorganized...
I find dr HDMI very expensive and I don´t think google will solve this issue. Maybe scene will do it eventually.
Well now I have a music streamer hehe, maybe I'll buy an fire tv or an apple tv...
Thanks a lot!

Interesting. Definitely sounds like your projector doesn't like what Chromecast is sending, maybe it doesn't like 1080p. Regardless, considering the cost of Chromecast I would just use it on another display or gift it to someone else and go with a more "full" player.

HDMI dock review

This is a bad and hardly structured review with a focus mainly on video playback. This is not a full review, and there's more things I want to test (and probably info I will post) for the future. It is also 4 AM, so don't expect any literary gymnastics.
So, I've had the (Euro) HDMI dock for a few weeks now (as well as the black leather sleeve, which is nice) but hadn't really gotten around to testing it. Primarily because I hadn't gotten around getting a mini-to-normal HDMI cable - yes the dock has a mini-HDMI output. The cable in question is commonly known as an HDMI "A<->C" cable with male ends on both sides.
Let's get the details you all know already out of the way. We're talking about the ECR-D980, more info here.
The dock itself comes packaged with nothing. No extra USB cable, no HDMI cable (or even converter plug), nothing. Keep in mind that these up the total cost of ownership for the dock quite a bit. I got the dock for about 29 euro, add about 20 euro total before you have a second SGT USB cable and a mini-to-normal HDMI cable. So that's 50 euro or about $70 US minimum cost at the time of writing, significantly more if you don't search a bit to find the cheapest deals. You don't strictly need the extra USB cable, but it becomes annoying in most setups if you don't have it - you'd be switching the cables location a lot.
The dock itself feels like a solid piece of equipment, much like the Tab itself. It features a 3.5mm audio out, mini-HDMI out, and 30-pin Samsung "PDMI" USB / power connector (the same connector on the Tab itself).
I started out testing at a friend two weeks ago, using his Sony soundsystem (several HDMI ins & outs) and his 42" high-end-4-years-ago Philips LCD. We were however completely unable to get it to work. Having no clue which component the problem was, we gave up after a bit. Note that his LCD doesn't do 1080p, but max 1080i (at time of purchase, even 1080i was rare). So I borrowed his cable, and today I tried it (with his A-C cable) in my home, on my Samsung 6-series 37" LCD that does do 1080p, without any special soundsystem. Note again that I used a converting cable, not an A-C converter plug. I know people have reported problems using those.
As soon as I plugged everything in, I immediately had display on my screen. We still don't know what the issue was at my friend's house, but keep in mind that it may be a requirement that the display device supports 1080p. The signal received by the TV was 1080p30. I think this is the maximum the device will do, as my TV does support both 1080p50 and 1080p60 as well (and I regularly use both those modes).
Immediate snags:
(1) First, the dock needs to be connected (via the USB cable) to a power, or HDMI will not work. I actually used an old HTC adapter instead of the Samsung one, that delivers 1a instead of 2a, and that worked fine. Connecting it to a computer USB port (0.5a) reportedly does not work, but I have not tested this myself (yet).
(2) Second, the Samsung USB cable you got with your Tab is really short, using an extender cable is almost certainly necessary for most situations.
(3) Third, the 3.5mm audio out does NOT work while HDMI is connected (reported by others, not tested myself)
(4) Last, the backlight will NEVER go off when connected over HDMI. Not even using the power button.
So, when you have it all connected, you will see one of two things: a really narrow output of your portrait screen, or a screen-filling output of your landscape screen. I advise everyone to put the device in landscape mode and enabling the orientation lock before connecting. Note that the HDMI dock is also a really handy standard for landscape mode!
When in the normal Android UI, you can clearly see the artifacts of upscaling. You'll see whatever happens on the Tab on the TV as well, scaled up (and not using a good resampler). The Android UI does NOT suddenly see a FullHD screen (as I expected, but some may be surprised).
However, some applications that go full-screen do see and use the FullHD resolution. I have not extensively tested this on many applications. For example, the YouTube app appears to see FullHD, but I can not be certain. The stock Samsung video player does see and use the FullHD resolution, as far as I can make out.
I have tested playback of the following videos, in the stock video player:
(1) Iron_Man_2-DivXPlusHD.mkv - 81mb, 2:30, CCV1 1920x800 23.98fps, AAC 48000Hz stereo, 4.4mbps
(2) Cowboys & Aliens - Trailer.mp4 - 174mb, 2:31, CCV1 1920x816 23.98fps, AAC 48000Hz stereo, 9.2mbps
(3) v.2009.s02e03.720p.hdtv.x264-ctu.mkv - 1118mb, 41:22, CCV1 1280x720 23.98fps, Dolby AC3 48000Hz 6ch, 3.6mbps
(4) the.mentalist.s03e12.720p.hdtv.x264-ctu.mkv - 1119mb, 41:48, CCV1 1280x720 23.98fps, Dolby AC3 48000Hz 6ch, 3.6mbps
These four videos all played fine, with audio and everything. V even had subtitles, and those worked well. However I must note that the button to disable subtitles is disabled while outputting to HDMI. Not sure what that is about. DTS is still on my to-test list, but I'll get around to that when we get the setup working on my friend's soundssystem, where I can also test whether or not the output is more than stereo or always downsampled to 2-channel.
The video output is pretty good, but not without buts.
(1) First, as stated before, the backlight on the Tab will not go off no matter what you do, and you will see one of the first frames of the video as a still on the Tab. You can however still use much of the videoplayer UI (which is suddenly slightly different: amongst other things options like brightness and scaling disappear), and that UI only appears on the Tab, NOT on the TV. Now if only I could control that UI, over Wi-Fi, with my SGS ... (might be possible through DLNA, btw, a nice test for the future)
(2) When you look closely at the image produced, you will see that the postprocessing is not quite up to par to the quality you get from CoreAVC or even ffmpeg on a laptop or HTPC or whatnot. The difference does really seem to be postprocessing though, not bad decoding or scaling.
(3) There is some shift in framespeed. Not traditional suttering you might see when the player cannot decode fast enough, though, the speed seems to be fine. I think this has to do with the fact that first the Tab has to scale 24fps to 30fps, which is probably done with some pulldown scheme, and then my TV has to scale that to 100hz, again with some pulldown scheme. I'm sure the videophiles amongst you will understand what I am talking about, even if the jargon is not correct. If you're not following, you are probably someone who wouldn't even notice it. Also note that I have all video-enhancing features on the TV itself turned off (as always). Enabling the 100hz motion interpolation mode makes the issue mostly disappear, but I really hate the "homevideo" effect you get when doing that. All in all, when watching a 40 minute show, you don't really notice it anymore after a few minutes, but if you're like me you know it's there and see it. If it were 1080p25 instead of 1080p30, the issue would probably not exist.
All in all, it does look good and works pretty well. Unfortunately, though most of these individual issues are small, together they are big enough to prevent this from being more than a casual playback device. It comes close, but not close enough to being a home-theater device. However, who knows maybe XBMC can be ported and we'll get past a number of these problems.
I won't make any claims as to whether the HDMI dock is worth the money or not. You know the price, and you have a bit of information here, and more in other reviews online. You have to decide for yourself it it's worth it. Hope this is helpful and/or interesting to someone.
For me the dock was totally worth it. The framespeed issue you describe is definitely there, but I do not notice that unless I am consciously looking for it. I have watched a lot of movies quite comfortably using the dock on Full HD TV.
And yes, if TV is not 1080p, for example just HD Ready and not Full HD, the video output is not HD at all. I think it's the same as Tab's screen: 1024x600.
"Connecting it to a computer USB port (0.5a) reportedly does not work, but I have not tested this myself (yet). "
USB from my computer (Kies drivers installed) works fine with the Dock. I have an HDMI capable computer monitor and this also works fine with the dock.
Thanks for the review!

Worked out of the box for me, through HDMI. Haven't tried 3.5mm jack. Have heard that complaint before though.
Nice review its a bit dissapointing for me that they chose the mini HDMI standard as there is plenty of space to have included a normal size plug.
Maybe I'm just annoyed because I have HDMI cables laying around but now need to buy a mini HDMI cable

100% agree
YouTube is great when you're docked. You can flip through videos and playlists on the tab while a YouTube clip continues to pay fullscreen on your TV - nice! It's a shame you can't play HD though.
I stripped the DRM off all the free movies that came with my Tab so I can play them directly through the dock. Inception looks great! You're right though, post-processing looks a little rough at times.
The dock is pretty overpriced for what you get but I'm happy with it all-in-all. If it came with a mini HDMI cable it would be perfect.
are you using a stock rom or custom rom? wondering if that will matter in regards to dock performance, i am on the rotohammer jme v4 and love how fast it is compared to the stock roms.
thanks for the notes/review!

My projector is 1024x768 and the dock work well with it, so 1080p is not necessary for it to work, and as a power source I use an external battery rated 500mh, so I guess a computer usb port should be able to power it.
My problem is that my projector doesn't have an audio out jack, and when the hdmi cable is connected all the audio port of the tab get disabled, INCLUDING bluetooth audio. This is why I now use this dock as an overpriced charging dock

As metioned in the first posting of this thread, unfortunately you cannot turn off the screen on the Tab when it's in the doc. When watching video's the first frame of the video stays visibile on the Tab the entire time. When your not watching videos the displays on the Tab and your TV are mirrored.
I buy the HDMI station dock and I find it no really good!
A HD photo is not so nice on the LCD, it ok buy when you see then at the real resolution with the camera, it's bad!
The only way that I can have good resolution is when i plug the tab into the PS3 like a hard drive annd the I see the same photos like they are and my videos arein real 720P or 1080P
I will returned it and wait for a new model or plug into my PS3
I just picked one of these up and was a bit disappointed with the video quality too. Videos looks great in HD on the Tab but jaggy and average quality on the TV - no better than a DVD really.
I bought one so I could connect it to the TV in my hotel room when I go on Holiday soon. Is it true that if you get no audio over HDMI, you can't use the line out at the same time? I was going to take some small speakers just in case the TV in the hotel didn't support audio (should be fine, think they're Samsung 32" LCD TVs).
I'm a bit surprised there's no settings you can tweak on the Tab other than PAL or NTSC to correct the overscan and advise on resolution and FPS.
Surprised about the quality, I loaded a webpage up in Xscope and could hardly read it on the TV, very poor. I genuinely thought it would be near HD. I could just take my 13.3" Laptop with HDMI out but that's 2.5KG.
At least I'll get lots of films on the Tab as there's no point putting HD ones on there if they don't look HD on the big screen. What an oxymoron that they look better on the Tab screen!

Can chromecast send audio out of device instead of HDMI?

I just received by Chromecast today and I have an older TV. I am using an HDMI to DVI converter so no sound is being transferred.
Would it be possible to keep audio playback on the controlling device instead of the TV?

Not that I know of. You could get an audio adapter, but it would cost more than the device. Best bet is that we can get a client ready for the Raspberry Pi, and that can use 3.5 audio.
I doubt it. The clever bit about the Chromecast is that *it* decodes the incoming stream; once started you can turn off "the controlling device" & everything will continue to run undisturbed.
To decode the incoming stream and send the video to HDMI but redirect the audio portion as an outgoing stream to another device...
I suspect that is too much of an edge case.
Your setup, as it stands, appears incompatible with how the Chromecast operates. I'd look into returning the Chromecast as unsuitable, resell it, or invest in DVI+audio out hardware or go HDMI.
Your Milage May Vary.

Looks interesting. Do you know how it handles the signal timings? That will determine how compatible the device is with VGA devices. Not all devices that accept VGA will accept video 720p or 1080p resolutions correctly displayed and centered.

Well he was already using a DVI adaptor so chances are likely he will not have many issues displaying 720 or 1080 since any monitor with a DVI will in most cases do well above those resolutions....
but the problem he is going to run into is that things like Netflix are probably going to require HDCP which he won't get with that device.
And no converter device or adapter available will ever get him the HDCP.

[Q] Setup issue. Black home screen

I've just bought a Chromecast device and I'm trying to
setup it. The problem is that when I plug it to the tv, a message appears
saying "Starting chromecast" and then the Chrome logo. After that, black
screen. Nothing appears. The setup program in my pc can find the device but
I can't see anything on the TV.
My TV model is LG 32LE5500
I tried rebooting the TV by unplugging everything and nothing changed.
Also I tried the Chromecast devide in another TV and it worked there, but it's not my TV and I need it to work in the LG one.
I've tried all hdmi ports and it's the same in all of them. The chrome logo and then black.
The last thing I did is to configure the device from the other TV and then plug it on the TV that doesn't work. I realized that the audio does work, I launched the YouTube app from my cellphone and I could hear the video, but again, black screen.
Could it be that my TV has a resolution of 1900x1080 and not 1920x1080?
Please I will appreaciate any kind of help, I really wanted to use the device and it's useless for me right now
According to LG, that's a normal 1080p screen.

More likely there's a router setup issue. This may help as a starting point -

Your TV is 1080p, so it's 1920 horizontal.
IIRC the boot logo sends 480p, then Chromecast negotiates with the TV as to what resolutions are supported.
Your TV might not be playing nice in the negotiation process.
So, try booting Chromecast without it connected to the TV.
Disconnect power from Chromecast
Disconnect Chromecast from TV
Reapply power to Chromecast
Wait for it to boot (wait until LED goes solid steady white)
Turn on TV if it is not already on
Set TV to Chromecast input
Plug Chromecast into TV input

Very strange. Almost sounds like an HDCP handshake problem.
Try the HDMI extender in case it's just not plugging in quite right.
Other than that, you can try disabling HDMI CEC (LG calls it SimpLink) and see if that makes a difference.
Do you know what firmware build it has? (Chromecast app will tell you)

Nice names.
Well, you're on the latest firmware build (15250) so either Google broke something in the newest update, or your TV is finicky.
Since your TV is Smart, it might have a firmware update available.
Wait... The specs say "TruMotion 100Hz" - is your TV PAL? It might not support NTSC input...

HDMI doesn't care about PAL vs NTSC frequencies by design, exactly why so many in the UK were able to adopt early last year.

While I agree that it shouldn't matter in this day and age, they still exist separately in the EDID data because of the differing pixel clocks.
It's possible (though ill-advised) for a modern display to reject an input signal based on it being 50/100 Hz or 60/120 Hz.
I deal with a lot of AV stuff and have run into this issue from time to time.
Well, TIL then.

I'm learning every day... sometimes the hard way.
Traditionally European TV sets have been more forgiving than their US counterparts, accepting NTSC "nudged" into PAL-60 or NTSC 4.43 in the analog realm.
While the transition to HD did unify the display resolutions and pixel aspect ratios (everything's square, yay!), the differences in refresh/sampling rates remained.
One day my friend, one day... everything will be 600 Hz or better so 24, 25, 30, 50 and 60 fps content will all be supported and play without judder or needing interpolation. :cyclops:
So back to the topic at hand, it's possible the OP's TV doesn't know what to do with a 30/60 Hz input from Chromecast, though that would be quite silly of LG to impose such a restriction. Still, silly happens more often than you think for all kinds of reasons (gray market sales due to varying exchange rates and import/export laws often is a concern, as we burden on regional support that got no revenue from the foreign sale).
TBH, I don't know for certain whether Chromecast is capable of 25/50 Hz output, it might be. But being that Google isn't selling it outside of US/Canada yet, I doubt they've tested it.
>> Anybody in Europe, can you confirm me whether Chromecast outputs 720/50p, 1080/50i or 1080/50p to your TV? <<

Thank you for all your replies,
For what I know, my TV accept NTSC but I'm not 100% sure. I am from South America by the way, in theory electronics here are NTSC.

That TV in the picture you posted is very similar to the one I have. Did you have any problem using the chromecast device?
The link I gave was from the Eastern Mediterranean, I was more curious about verifying your resolution at the time. There's a 60/120 Hz (NTSC) version of your set, same model number, popular in several South American countries.
I apologize for adding the confusion.

Hmm, should work.
Worst-case, since you have other displays that Chromecast does display properly on, you could try this: (it worked on 13300, haven't had need or opportunity to try it on 14975 or 15250)
Locate working monitor and LG TV in close proximity
Connect Chromecast to working monitor and wall power
Once Chromecast is booted, unplug Chromecast from monitor only
Plug Chromecast into LG TV
Likely this will not survive a Chromecast reboot though...
I've got a Sanyo DP50740, and my Chromecast is now showing this same behavior. It used to work fine, but I think that the update to firmware 15250 broke something with hdcp in some TV's.
I filed a bug with Google, but the end result was that the google helpdesk can't tell what was updated in the latest build.
I suggest you file a similar bug with Google, so that they see that this is happening with multple TV models.
Until they fix this I'm stuck with a paperweight.

Nope, tried that. The only thing I haven't tried is to boot up plugged into another device then plug in. Don't have any portable monitors with hdmi input. It might be that they fixed this glitch in the latest firmware.
This is the annoyance of allowing google to update firmware at will. They can break your device, and there's then nothing you can do except wait for the next release. That's why I encourage the original poster to file a bug with them. That's their only window into what's happening.

The no HDMI and different HDMI scenarios should be different, they have been in my case at least, but understand not having a practical means to try.
Agree. That's the danger of forced updates.

For those having problems with LG tv's not displaying chromecast

This was driving me.crazy for days. My receiver would play chromecast on my LG tv but when plugged directly to any hdmi port on my LG tv, nothing would happen. My LG would say starting chromecast, then nothing, no signal. I tried all Google troubleshoot recommendations and nothing. Finally, when I changed the aspect ratio of my tv to 4:3 then unplugged and plugged the chromecast back in (movie was already being casted from Netflix) it finally recognized it and I was showing the movie! It worked on all hdmi ports, after being able to cast, i then changed the aspect ratio back to just scan or 16:9 . Hope this helps somebody

No issues with my lg 2013 led 3d model. Set to 16:9 as normal and has always worked. Wonder if it is more a model specific issue. You should post your TV model info for others to compare as it isn't really "lg TVs" exactly

There have been many different TV's with this issue, especially with LG TVs. My sanyo has a similar issue, so I'm about to try this.
There have been many similar reports over on the chromcast google users forum:
https://productforums.google.com/forum/#!forum/chromecast
I just jumped on over there. A few here and there but there doesn't seem to be any rhyme or reason. What I am getting at is we really need model number of TV, how you have it setup, is powered by USB wall adapter or USB port on TV, extension vs no extension. If we can get model info and setup info we might be able to learn more. Even TV firmware will help. From there we might be able to find another person with the exact same TV to learn if they have the same issue or not. Just want to help of course so don't take this the wrong way. It could be something simple.

It could be something as simple as a timing issue, especially in the case where Chromecast is powered by TV USB port.
Counter-intuitive as it may seem, HDMI prefers being plugged in to a "live" receiver for the handshake to happen. If the TV doesn't listen to HDMI while powered "off" but Chromecast still gets powered, Chromecast might not negotiate the HDMI handshake properly - and that usually requires a disconnect and reconnect to renegotiate.
IMO Google should really push wall power more. TV power is asking potential trouble if the TV powers off the USB port while flashing an update. Unless the TV specifically supports connecting a USB hard drive, I don't expect it to have any sort of predictable power output. Yes, I know USB spec says it must, but I've had numerous USB hosts with variable output, or at least that's what USB Voltage Doctor tells me...
I actually did this this weekend....
I have my TV mounted to a wall like most people and there is a pair of dual outlets on the wall that the TV plugs into...
I replaced one of the standard AC outlets with one that had a single Grounded AC and Two USB ports and now power my CCast with those.
Most folks use the TV USB because it hides the wires but for the price of $5 you can replace a outlet and get a much better USB Power source.

Someone over there, I'm assuming who works at google, keeps insinuating that they only have problems with TV's that have bad EDID's.

Would be easy (but not free) to test with an EDID replacer like Dr. HDMI or HDMI Detective but to be honest I would expect other HDMI sources like DVRs and Blu-ray players to also have trouble if it was truly an EDID issue.
I know some very old (early days of HD) sets report they accept 1080p but don't actually display it, which is an EDID issue, but that really shouldn't be happening for anything modern.

Yes, you would think, but google hasn't really made too much hdmi input equipment. The major things that are failing with hdmi issues are non-1080 native TV's such as 720 plasma's, and a lot of LG problems. I think that the latter additions to the edid standard to accommodate hdtv signals might be the issue.
Of course it would be nice if Google actually listed the TV sets that they are having issues with, but at least one person listed that when they talked to google support direct, they said that the one TV wasn't supported right now.
42Lw5300 from the wall outlet and from the tv usb both work
When I first got the cc it worked flawlessly on the tv hdmi input. Then I decided to plug it into my av receiver then when I went back to the tv recently, it wasn't working. All I got was , starting chromecast and then it would switch to the LG screensaver saying no signal. Numerous hard resets nothing..then I did the change screen format thing and it worked all the way

I did the switch my tv thing to 4:3 after I notice when the cc starts it looks like the starting chromecast font was at a lower resolution...so by switching it I thought it would recognize my cc at that a lower resolution

AFAIK the Chromecast boot screen is 480p, but after that Chromecast will try to negotiate 720p or 1080p.
Aspect ratio (4:3 or 16:9) just determines how your TV handles the signal (don't stretch or anamorphic stretch) - it shouldn't change what the TV communicates.
I was also having problems with my LG television and Chromecast. Chromecast turned on via the LG's usb port but tv was pitch black. I had to pull the powercord off and plug it in 2-3 times before the tv worked. Turns out that the LG had faulty panel.. and the TV was like that from the first moment I bought it. Hooray for warranty! The tv was 2 weeks old when I had it repaired.

Chromecast logo and no image

So i have top tier problem
When i turn on my chromecast screen is just black it shows Chromecast.... then google logo aka multi color G and then just black screen if i stream stuff it does output audio (chromecast audio update jokesaside) i tried 2 chromecasts and both same effect (chromecast 1st,2ndgen) question is are there any ways to fix this as in shop they will throw bricks at me if i bring another chromecast claiming that its faulty :silly::silly::silly::silly:
It could have an issue with your WiFi.
Try it on a different one.
If I remember right, at least the 1st gen, supports only 2.4GHz routers.
So find one, or try it on a few.

I have like the same setup like you so unfortunately there is no fix. Chromecast will work only on the formats 720p or 1080p. I purchased a cheap Miracast dongle and works like a charm on a set-up like yours. Unless the converter can be setup to 720p you will be able to use it...
