[Q] mhl hdmi black levels all wrong! ignore.fixed! - Xperia Z1 Q&A, Help & Troubleshooting

Edit fixed it turning off video conversion on receiver haha
I have an issue running hdmi out from my z1 to my TV. I'm using the official mhl adaptor and the TV is Sony hx853. However, the black levels are terrible. It's like the localised dimming is just not working at all. It's horrible to see everything so washed out I don't get it on any other hdmi output devices. The cables are absolutely fine and obviously, there are no tweakable settings as the hdmi signal should be bit perfect going into the receiver. Could it be a faulty mhl adaptor? These official ones are really expensive :/ be grateful for any help or insight into the matter! Thanks.

[Q] HDMI Dock digital audio out

Just bought the dock thing and tried to put it to work with the HDMI out on a philips HD tv, and it happens that there is no audio at all. I know the analog speakers are disabled when the HDMI is working, the audio provided by the HDMI is really not working.
I have no clue of what is happenning. I am getting just the image fom the tab but no audio at all.
I hope someone knows what is going on and help me.
I'd really appreciate the help.
tks.
Hi. The problem seems to be application dependent. When I use RockPlayer and VitalPlayer digotal audio is there through a docking station. Other players including stock one output just analog audio. Regards. K

Tks mate but when I used the rock player I am still getting no sound at all. Its not just the rock player but even the native one or any music player. The sound isn't passing through the hdmi cable.

I will conect the tab to the TV set in few minutes to double check my findings once more. Btw I use the latest firmware MCD. Regards K

Actually, I can now confirm that I have digital audio output from the docking station with any of the mwdia players including the stock one. When initially started, all the players mute the audio when the tab is in the station. Pls volume up through hardware keys and you will have the audio output. Regards K

The volume is up when plugin to the dock and yet I get no sound changed the volume up and down but no answer. Have two Philips televisions and different models here and on both I get the same issue, no digital sound. The analog sound is fine when plugin the av cables. Now I wonder if the hdmi cable isn't working or is the tv that doesn't like the dock.

Can you post the details of the cable including it's version number. It may be you have an incorrect cable.

I bought the dock to connect the tab to my projector and I found out that when the hdmi is in use all the audio will go to the hdmi cable.
Now my projector has very poor speakers and no audio out. I really hate that I can't use my Bluetooth speakers when using the dock.
There is some way to split the hdmi signal in video and analog audio?

Still have video and no sound
So, I still have the problem. I have the dock connected to power from the supplied (5v 2a) adapter. I then connect it to my tv. Video works great. I also speculated that maybe I had to use the 3.5mm jack for sound but that isn't working either.
I also have an adapter for rca-out and that's working fine, but I'd rather have the better quality available to me via HDMI.
I've got no solution yet. As I did, put here your the specs of your cable, maybe its something about that cable tho.

hdmi cable info
So, it's still not working for me. I don't have the box the other cable came in so today I went out and got a new one. I now have one of these:
http://www.digitalwarehouse.nl/hdmi-kabel-type-a-type-c-mini-2m.html​
It is a type-A <-> type-C high speed HDMI Cable. I told the guy when I bought it that it had to be v 1.3 and he said it was though I don't see that on the box any where. I know for sure that my original cable was a v 1.3 because I remember reading that on the box when I bought it.... The only other info I see on the packaging is this:
Transfer rate: 10,2 Gbit/s
BandWidth 340 MHz
ARC audio return channel​
My problem persists and to eliminate other potential causes, I've now tried it on another TV as well: no dice
It could very well be the cable. I have had some HDMI cables not output sound from DVD players. Here is the cable I bought and it outputs everything, sound, video the works.

Having my tab on my TV rocks
right cable
Well, I live in sweden. Ordering from Amazon is not ideal for me. Is there any other way I can get an indication that it might be the cable? I am loathe to keep buying cables assuming that it's the issue... I mean, is there something on the cable itself that I can look for? Certains pins or something?
/geir
I dont know that much about HDMI cables, does kinda seem pointless to keep buying cables.
Possibly google it? I would say try it on something else, however nothing else you own probably need A to C hdmi connection.
All I know is thats the cable I bought and it works perfect for me on my 4 year old projection LCD
Tested the cable with something else...
Ok, so my daughter has a camcorder which will take a mini hdmi cable. I just tested both cables with her camcorder and both of them give me video and sound...
If the cable is the issue it's definitely not because it isn't at all capable of handling audio
Any chance anyone has any other ideas? I just have this feeling there is something else going on... Like maybe I need to flash to a new version or something.
I have a european tab, in case that matters.

[Q] HDMI adapter issue (MHL)

Hi,
I just received an OEM Micro USB to HDMI adapter today.
I connected my Note to the adapter and then to the HDMI cable of my TV.
Unfortunately there is no HDMI signal on the TV side.
Now, I don't know howto activate TV output on the Note. I don't even know if that's possible.
Can anyone guide me on how to activate HDMI output on the Galaxy Note ?
Should I make any settings ?
Should I play a video ? (or would it give out video from HDMI even at home screen ?)
Should I power the phone and/or the HDMI adapter through USB ?
Thanks.

Connect HDMI cable to MHL adapter, and other end into TV. (duh...)
Plug your charger cable into the MHL adapter. (output won't work without this)
Plug your MHL adapter into Note. (no configuring required!)
Everything you do on your Note will be mirrored on your TV/Screen, at the Note's native 1280x800 resolution. Plain and simple!
Video's that are played via the MHL adapter will be played at their own native resolution, up to and including 1080p.
Enjoy!
thank you.
it doesn't work unfortunately.
maybe my adapter is not working but it passes power through USB.
how can I understand if it really doesn't pass HDMI ?

It's possible that you have a faulty adapter. It should just be plug and play, but you have to make sure that the adapter is receiving external USB power in order for it to work.
ok; it works now.
the micro USB connector was not fully connected...
thanks.

and what rom and kernel are you on ?
I'm on stock running ICS and I get funky results, sometimes it works for a minute or two sometimes just a few seconds. The problem seems to be on the TV, a Sony Bravia, the HDMI setting has to be Wide for picture quality (it has zoom, smart zoom, wide, 16:9 and 4:3) but as soon as there is some glitch in receiving data from the phone the TV begins to scroll through those settings to regain a signal and I can't force a setting on wide for the HDMI connector, only for one of the SCART connectors.
The frustrating part is that it works flawlessly when I connect an Asus Transformer. Could it be the MHL's USB connector? If that is the case how can I check it?

Just in case anyone relooks this up.
Connect everything. Then REBOOT PHONE/NOTE. The TV will then detect it auto.
Hope this helps someone !!
It didnt help me... my sony bravia 32" tv just wont show the gnote's video. the same adapter works fine on my samsung 32" tv but not on the sony. I have even upgarded the sony tv's firmware too. tried changing to "Wide Zoom" settings and other things but still no video showing, although the tv does know there is something plugged in to HDMI port 1.

Non HDMI TV use.... Q's and hopefully answers.,

Ok I'd like to know if an HDMI to composite converter will work with chromecast...?? And I have some answers.
An HDMI to VGA converter . i can confirm that definitely DOES NOT work.
An HDMI to composite (cvbs) converter DOES work. I have one of the cheap small square white ones you see a lot with phono audio outputs and the yellow av out. it requires USB power to give me a signal so sorting out 2 USB ports for use with a CC is a minor pain.
Picture quality is clearly not close to Hdmi , think 'fuzzy'. but on our lcd, with a boost of saturation, noise reduction etc watching material is perfectly acceptable. Sound seems good as I'd expect.
Problem is our TV has HDMI but no hdcp (dont ask) rendering it mostly useless and new TV is not on the cards yet, so this has helped.

Calrad makes an HDMI to Component video adaptor that should work for you, providing your TV has component video inputs. part number is 40289. It should cost around $179 retail though, so my recommendation would be to take the $150 and invest in a newer TV!
I have a Chromecast connected to an old Sony 20-inch 4:3 (not widescreen) tube standard definition TV with only S-Video and Composite inputs.
Here's how mine is connected:
Chromecast
HDMI to HDfury2 Component (bought for I forget... more than $100 a long while ago, from a previous setup)
Component to AVT-3190 HD/VGA to Component/S-Video/Composite down converter (bought for $119 used on eBay)
S-Video to TV
Audio (analog) to TV
Both the HDfury and Chromecast require USB power, but I have them both connected to an iGo MicroJuice power adapter that has 2 USB outputs ($9.99 from Best Buy clearance).
The down converter has a wall wart too, so it's 2 power plugs.
Result:
Video
It's a bit fuzzy, but what do you expect for 720p/1080p being downconverted to 480i?
Aspect ratio is correct, because the AVT-3190 down converter has switchable aspect ratio conversion (ARC), so not only is my video downscaled to 480i, it's also being letterboxed, so the vertical resolution is even less than 480i for widescreen casts. This wouldn't be a problem if you have a widescreen display.
Audio
Is fine. I'm getting analog output from the HDfury2. It also has optical digital output, but I haven't tried it as I'm just using the TV speakers.
What doesn't work:
Automatic power/input control via HDMI-CEC. Obviously this doesn't work because HDMI-CEC isn't supported by the HDfury2 as there's no way to translate that into its just video and audio output.
Given that this is about $200+ of gear to make a $35 device work, it's probably not smart. But my case is special, and I'm sure there are others with special cases as well (projectors, in-wall displays, etc), so there you go.
If you have a HD-capable display that just lacks an HDMI input, you would just need the HDfury2, not the down scaler, so that cuts the cost in half. That's how Chromecast works with my old HD projector.

HDCP problems and other woes...

Hi All,
So I had what I thought was the genius idea of buying a Chrome Cast to hook up to my old projector for instant Netflix et al. cinema in my living room, it's all set up... screen, speakers everything but there's just one small problem, no picture.
The reason it isn't straightforward forward is that my projector is old enough not to have an HDMI port, though it does say that it supports HDMI on it's DVI port using an adaptor. (Which I can't find). Also of course I'd have no sound.
What I have...
So with a little research I bought this HDMI to VGA + 3.5mm Jack Audio Cable Video Converter Adapter, I also bought a couple of gender changers, one VGA and one HDMI to get the whole lot to stick together.
The projector is an Optoma ThemeScene H57, so quite old but actually pretty decent (hence reluctance to take the plunge on a new one and also because this was supposed to be a cheap project)
What is happening...
What I'm experiencing is a black screen, which I am now attributing to HDCP problems... the projector scans and detects that there is a source plugged in the way you'd expect and looks like it's gone through the process of adjusting to that source signal and then just happily displays a black screen. Occasionally it also says "Out of Range". The sound comes out garbled when trying to play netflix or youtube.
I have tried it with a VGA to DVI adaptor into the DVI input to witht he same result.
I have also tried plugging my Nexus 10 into the HDMI input on the convertor, this yields a different result, white static, but still no picture.
The projector does work... it's even briefly displayed a chrome logo when I tried factory resetting the Chromecast while it was plugged into the projector (via the adaptor obviously) but then just returned to the black screen.
A weird caveat to all this is if I play something on Play Music then I still get a black screen but the sound comes out fine.
What I plan to try
I read that HDCP can cause problems like this and that it can sometimes be fixed using a powered HDMI splitter. Apparently this negotiates the HDCP handshake with the Chromecast and then passes on the signal to the two output ports, which sounds a bit dodgy, why is it so simple to bypass? Plus it's £30 for one of those which means my cheap project is getting more and more expensive.
So...
Any help on this would be really REALLY appreciated. Please.

I'm afraid the only solution is to get an HDCP compliant projector...
CCast will only pass on HDCP info from the Device it is plugged into, but has no HDCP of it's own. And it can not be faked.
The Adapter will also break any HDCP as HDCP is meant to deny you the ability to do what your trying to do in the name of not letting you make copies of the content.
You will be fine with Content that does not require a HDCP signature to play (self ripped movies or non-DRM materials) but something like Netflix has little chance of working without some HDCP compliant device being connected the the CCast.
You can get a standard HDMI DVI adaptor for cheap, and maybe this will allow HDCP information to be kept. However you may be unable to keep the audio stream without a more elaborate device.

It is actually HDCP compliant... so does that mean it's the adaptor that's breaking it? Is there such a thing as an HDCP respectful adaptor with an Audio splitter?

Yes you're essentially converting a Digital signal to analog and HDCP only works via Digital.
A Real HDMI to DVI adapter as suggested may help but make sure in the specs it says it will pass HDCP.
And do make sure it also has Audio Breakout.

Your projector is a little newer than my Sony VPL-HS10, but it might have the same issue - the marketing wasn't 100%. My VPL-HS10 initially said it was HDCP-compliant on the DVI-D port, but ended up that it isn't. Well, it might be for a few select devices, but it isn't up-to-spec for the general standard.
What you really need is an HDCP stripper, but those are illegal in most parts (especially the US).
Your other potential problem is that the adapter may not be converting the HDMI timings over to VGA, and rather expecting the receiving device to compensate. Some can, some can't.
The specs for your projector says it has a DVI-I port, so it might accept analog on that port.
So first I'd try connecting DVI-to-VGA adapter (the ones that normally come with video cards to get VGA out of the DVI port) and connecting Chromecast --HDMI--> HDMI-to-VGA --VGA--> DVI-to-VGA adapter --DVI--> Projector and see if you get a different result on the DVI input - sometimes the scaler is separate or different for different inputs.
If that doesn't work, I recommend HDfury2 or newer - beware of counterfeits as there are many fakers online. I have successfully used HDfury products with my Sony projector from various sources. You'll want the HDfury2 or newer to get the audio breakout, which is a 3.5mm (1/8-inch) analog stereo and digital (optical TOSlink).

Chromecast 3 (2018)

Hi everyone!
Does anyone knows a method (either hardware or software) to force the Chromecast to output at 720p?
Background:
I have a DVI monitor and I used a simple HDMI to DVI adapter to plug my laptop in it.
My laptop died and I decided to use a Chromecast and my phone as a replacement.
After the Chromecast arrived and I plugged it in, I turned on screen mirror and hooked my kb/m to the phone and everything, only to realize that the sound was also being streamed to the Chromecast.
Needless to say that my monitor doesn't have audio output.
So I got one of those HDMI audio diverter to draw the audio and feed it to my audio system, so far so good.
I used my laptop to game was well, so after starting some withdraw from games, I decided to grab my PS2 console and got on of those PS2 to HDMI dongles and play some old-school games, then I started facing an issue: swapping cables.
To fix that I got one of those 3 port HDMI hubs and plugged both devices to it.
However the monitor is 720p, the HDMI audio diverter knows that and replicates this information to it's input port which makes the Chromecast display in 720p.
But the hub does not, it report it's 1080p making the Chromecast send 1080p video signal and the display only shows a black screen because of it not knowing how to deal with that.
So if there's a way to force the Chromecast to display in 720p it would be my salvation.
So if anyone out there knows any possible solution, please, I would be really grateful.
Thanks everyone!
