I have a little Aiptek t20 led beamer, about the size of a mobile phone, which powers entirely by usb and get's it's visual data by usb.

Would connecting the device to the samsung phone require more than just an incredible amount of coding? Or could there be hardware limitations?
It was dirt cheap, and an watching movies from my phone on the ceiling or a wall would just be amazing.

I recently purchased a 3.5mm to video/audio cable for my samsung captivate and I am noticing that the quality of the videos on the 46" LCD TV is not that great compared to when i watch the same videos on my computer. The cable I purchased is a Scoshe brand that I found locally from Fry's Electronics.
Is the sub-par quality due to the phone output or the cable itself? What has been your experiences with TV-Out?
Thanks.
You're using a VGA cable, you'll never get HD quality content. It's akin to trying to run a VHS on your new 46" TV. It'll just never look as good as the HD content you've come to expect in the last few years.
For me, it works well enough on my GF's old 90's tv if we're going to watch a movie or some TV shows. I would never use it on my TV at home though.
dude not vga, rca, aka composite video. composite is a notch above vhs and a notch below dvd. so yeah it's the tv out and the cable.
hopefully the micro usb to hdmi will work on the captivate with a future update. there are reports that it works on the epic. if not you can share with dlna via allshare.
i have a $50 media box thing from netgear and it works but the phone cant push the video to it you can only tick the video for playback (dont add to playlist) and let the other end play the video. also windows media center can be a dlna server and an xbox can play it as a media center extender, the ps3 is also dlna certified. there are also upnp apps in the market that should work with xbox. and ftp and webdav apps that will let you mount the phone as a webdrive or access with a browser. i know many of those options are great in the home but useless for travel and if your home you dont need it anyway.
the netgear device i have is very portable but unfortunately you still need a usb wireless adapter to use it, im sure there are similar devices that have built in wireless but may be more expensive.
Thanks for the respones. Would you suggest getting a "higher quality" cable or am I just basically stuck with what I got? The pictures and videos look blurry (and pixelated) when I view them on the TV and I just want to know if it has anything to do with the cable.

live with it till the usb to hdmi thing works
edit; if the cable feels very thin and fragile it may have poor noise rejection, some are not sheiled very well. also if the you had to mix the colors around to get it to work that's not good. video cables are a different impedance so you need to use the yellow one for video. i know 3.5mm av cables dont follow a standard format and i dont know if you had to mix and match connectors to get a picture. but on a 46 inch tv you wont get good quality no matter how high the cable quality is, it's just an old inferior technology and why the make s-video, componant video, vga, dvi and hdmi.
I have a 46 inch LCD and have attached the phone to it. A HD movie looks ok, but not near as good as running via the PC at 1080p via HDMI. When and if they get the microUSB to HDMI working, we should see an improvement.
Hi all,
I know there have been other postings regarding this, but none have helped me solve my situation:
I have a "stock ROM" AT&T Note 2, and have tried two different Smart Dock units from Fry's. I get NO usable HDMI signal from either when connecting to my ASUS V228H monitor; the HDMI cable/monitor have been checked as working by connecting my DVD recorder up and successfully playing video content. USB connections to a wired keyboard and mouse worked well on unit #1, for some reason not on unit #2. There was no improvement when I rebooted the phone into safe mode. Lastly, the phone is correctly recognized by a PC when connecting via USB (MTP mode).
I'm ready to scrap the whole Smart Dock idea and instead buy an MHL-to-HDMI adapter and bluetooth keyboard/mouse combo, which I think can be found with total price just around that of the Smart Dock... unfortunately, I guess there's no "splitter" that could let me hook a hard drive up as well, like I could with the Smart Dock.
Does anyone have any ideas? I of course would hate to have to hard reset the phone, but might do it if there's really a good chance of it helping.
Final question: is it possible that the microUSB connector at the base of the phone could get damaged in such a way that USB to PC connections work, but MHL video does not?

did you plug the dock into an original Samsung charger?
did you reboot?
mhl takes a lot of power, so you need to have the charger plugged in to make it work.
and the usb port can get stuck in a certain mode if you've used it too much without rebooting, a simple reboot will reset it.
I am using the new micro-USB to USB cord connected to the wall charger (FYI, plugged into a power-strip, not directly into a wall outlet, would that actually lead to MHL getting too litle power?). The phone was recently rebooted. I have typed this response using a USB-connected mouse, so at least that's working. HDMI is STILL not working.

I'm guessing that unless it's specifically stated for the gn2, like the samsung dock, the microusb connector is using 5 pins instead of 11. That's the issue you'll have with mhl adapters, too: find an 11 pin, or buy the 5-> 11 adapter.
If it says compatible with the note (not note2) or evo, that's a pretty solid guarantee it's using 5 pins.
-----
I would love to help you, but help yourself first: ask a better question
http://www.catb.org/~esr/faqs/smart-questions.html
in this case the amount of pins is irrelevant. (edit: unless you didn't get a note 2 smart dock)
have you tried a different screen/TV and cable?
there are multiple versions of HDMI, and your cable or screen may be sufficient for an old DVD player but not a newer device.
Interesting that nowhere on the Smart Dock's box does it say "compatible with Note 2". But looking up the part # on the Samsung.com accessories site yields the following description:
Smart Dock Multimedia Hub
EDD-S20JWE
Compatibility: Galaxy Note II and Galaxy S4
As for HDMI protocols changing over time leading to incompatibilities... WTF? They don't need to create specification version numbers like USB to clue the user in? I will test your theory with an MHL to HDMI dedicated connector purchased today. If you're right, even this device won't work with my monitor...
This is going to sound like the annoying tech support people on the phone but... are you sure everything is plugged in tight?
I only ask because when I first got my smart dock I was getting picture but no sound with my hdmi cable and I was about to try a different cable but decided to try replugging everything first and voila...it started working!
It didn't make sense to me because it must be plugged in if it's working even a little but apparently either the phone wasn't docked all the way or more likely I hadn't pressed the hdmi cable in enough.
Would be nice if it's that simple in your case. Good luck!

Thank you for the suggestion. Yes, I had tested the Smart Dock's connections to make sure all were tight. No improvement.
I have given up on the Samsung Smart Dock for now. A "rig" that appears to be working is as follows:
1) Cirago MHL1000 MHL-to-HDMI adapter.
2) Mobile Phone->Voyage adapter (Micro 5 pin to 11 pin)
3) Comkia 3 foot HDMI cable.
4) ASUS VE228H monitor
5) HYPE Bluetooth Curve optical mouse
6) SMK-LINK Versapoint Bluetooth Slim Keyboard
You are definitely right about needing to check on the connection status of the various connectors. I periodically lose the HDMI video signal, which requires that I press the MHL adapter's plug tighter into the 5-to-11 pin connector. Yes, I also have the case off the Note II when attaching everything.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app (using the rig above).
Okay, I'm noticing that the HDMI signal gets lost every 5-10 minutes and blacks out the monitor for 5-10 secs. I also have been having the issue of definitely less than 1080p output (not sure if even 720p) except for video player and Angry Birds Star Wars which do look good.
Is this a problem of the Cirago MHL1000 plus 5-> 11 pin converter, which would be solved if I just spent some more bucks on a Samsung HDTV cable with 11 pins? Will the Samsung MHL 2.0 cable for the S4 provide better output for a Note 2 than the Samsung S3/Note 2 cable?
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
Okay, I sucked it up and bought the Samsung MHL 2.0 HDTV cable for the S4 and backward compatible with the Note 2. I think I've gotten things as good as it's going to get. Video out is stable and actually at higher resolution than using a Cirago cable and a 11 to 5-pin converter.
I unfortunately have no USB input capability for hard drive access. Is there any adapter to insert in the "circuit" to let me attach a HD to the Note 2 if its MicroUSB is already occupied by the MHL to HDMI cable?

hi
Hello, I have a problem when connecting a peripheral (mouse, keyboard, etc) the screen automatically flips and turns black, saying, which it is connected by hdmi too. that's not right.
otherwise it has explain, does not leave me connect the mouse and keyboard, because the s4 assumed that this also connected the hdmi.
Hello World,
I am close to giving up on my brand new Galaxy Tablet - and this after spending a lot(!) of money on the whole setup.
For some weird, bizarre reason Samsung seems to have decided not to allow the PM-900 tablet to charge and use the USB data port at the same time.
Try as I may (and having spend over $50 on all kinds of Y cables and USB hubs by now), I can only use the USB port only for data or for charging, but not both at the same time.
This makes it impossible to work over prolonger periods, as I find myself plugging & unplugging cables all the time (which I sure will do the port mechanics a lot of good along the way, too).
I found a neat trick involving cat'ing some file in /sys/devices/platform/sec-battery/power_supply/battery, but that won't work for me - even so I am rooted and on the latest Cyanogen Mod Kernel for this device.
From the way it looks, there is no pershoot driver for changing the charger settings included in the CM firmware that I flushed, and I can't find any PM900 specific pershoot firmware kernel for the PM-900 either.
W/o the ability to force USB charging on the tablet, I'll have to dump the whole thing, as I am desperately trying to set this up as my laptop replacement.
For the life of me I can't understand who came up with this brain damaged design, but I am using a high power charger which delivers 2A through the cable.
So its not the charger - which I also proofed by charging the unit w/o problems by just disconnecting all other devices (single cable connection).
From the way it looks, the tablet stops charging the moment the current drops even slightly below peak (meaning *any* other device is hooked up on the bus, too).
Those other devices consume very little current (USB microSD card reader, mouse adapter, etc), but its always only a "one way street" (charging or data use, but never both).
I need a solution to this, or this Samsung gets the boot - and this would be the last Samsung tablet I'll ever buy!
Any real help is appreciated.
Update:
I finally found out what's going on.
By switching around Y cables and USB adapters like there is no tomorrow (all bought and paid for with precious ca$h), I could finally narrow down what's happening.
THIS UNIT WILL NOT ACCEPT A CHARGE VIA AN(Y) OTG CABLE !
It'll accept a charge even from the most flimsiest of non-OTG cables, and from the cheapest of USB adapters (as long as its close to a 2A charge current), but stick anything OTG in between and its curtains.
This brain damaged design means that a tablet costing almost twice as much as a budget laptop can not be used for anything other than playing silly Games from the AppStore (now called PlayStore for just that reason?) and to post selfies on Facebook.
Anything even remotely approaching serious work, requiring to hook up peripherals like a USB mouse, keyboard, hard disk a.s.o. is utterly out of the question.
And no, Bluetooth is not always possible with such devices and WiFi setups force me give up my Internet connection.
This is just stupid, and I will now have to *seriously* rethink my entire "laptop-b-gone" approach.
I think Android tablets are just not ready for serious work, and maybe they'll never be much more than playtoys for kids and selfie aids for pimpel faced teenagers.
Off to eBay with this Samsung crap and back to Intel afterwards
Update #2:
By sheer accident I have found that there is ONE HW solution for this ridiculous limitation of "No charging via OTG ":
LAVA SimulCharge USB 1-port OTG Adapter for Samsung Galaxy Tab 4/S/PRO - Model TL-002
The problem is that gimmick may cost u a bundle, depending on where you buy it (at least here in the UK) and since they are the only ones making one, I doubt that's going to change.
WTF is up with that? This would be Samsungs job to offer us a(n affordable) solution like this!
Hi guys, I need to project the screen of my Tab 3 7" T210 on a TV that has both the hdmi connection that the usb.
I bought a cable network which on one side has HDMI and the other has both USB (to connect to the TV or phone charger) and micro USB to connect the phone precisely.
With the galaxy note 4 This cable works great, but with the tab 3 7 "does not go .... the tv says no signal, while the tab is not even the micro USB connection sound.
There is of special cables that "force" the screen projection of this tab on the tv?
Or maybe something universal that can be projected on the TV screen of any device?
Pretty sure the tablet has to have specific support for the feature. I'm not sure if the tablet does, but from the looks of it it doesn't
Operating system:Android™ 10
Chipset:Amlogic S905X3
CPU:Quad-Core Cortex-A55
GPU:ARM Mali-G31 MP2
SDRAM DDR3: 2 GB
FlasheMMC: 8 GB
But the device has Built in Ethernet (100mb), Type A USB 3.0 Port and Type C USB (Phone charging).
Having all the ports built in means we don't need to buy adapters / otg cables.
This is the first review I have seen:
Its big and ugly, and what the friggin 1992 is with that remote control? Looks like the USB-C port is only a 2.0, which is pointless. The official specs say it has a separate barrel jack for power -- not the USB-C port.
Also note that "OTG" doesn't apply to USB-C. The concept of "OTG" refers to the BACKWARDS use of a socket meant for a peripheral (mini- or micro-A), but USB-C is a genuine dual-purpose socket.
To be honest, the ability to plug stuff into it really isn't that critically important. I do see lots of people worried about adding USB storage to it, but that seems to be a pretty weak purpose since being a network connected device, you are free to add unlimited storage via the network, which is much more useful since that would be accessible to ALL of your equipment and not just the one its plugged directly into. For the most part, the USB port is good for an ethernet adapter, and google sells a nice one with a power adapter. The only other useful peripheral I can think of is maybe a video camera, but only if you need to use your TV for video conferencing, which yes, is a useful purpose.
But.... Nokia? Isnt that just one of the old dead names from the last century like "blackberry" that is now run by some unpronouncable arm of the people's republic of china? Consequently, I wouldn't trust a box with that name on it any more than pick-a-random-tv-box-from-aliexpress.
The only thing nice I see, is that its apparently got the "old" android tv launcher, and not the "wtf were they thinking?" one.
You are correct about the type-C port.... its just for charging only !
