[Q] HDMI dock issues

Hi All,
I have a T-mobile tab with an HDMI dock and I have been using it as my media center ever since the motherboard to my HTPC has crapped out. I'm currently running overcome 1.4.2 with UC/OC kernel. My tab works fine with the dock and by that I mean playing movies or streaming from the internet from apps such as "TV shows stream". However when I activate bluetooth it disrupts my viewing anywhere from 8 to 15 minutes whereby causing the video that I was watching to restart. This has happened on my previous Roto rom as well. Again, once I deactivate bluetooth, it works fine. I'm using a logitech PS3 bluetooth keyboard to surf from my couch. Even without the keyboard connected to the tab this problem still occurs. So something with the bluetooth is causing these weird restarts of my media.
Does anyone else having this problem? It is really annoying. Perhaps modifying the bluetooth script or something to that effect is needed. Any ideas anyone? Otherwise I love my tab and even more so with the use of the dock.

Are you using wifi or 3g data when you are in the cradle?

I'm on wifi. Never tried it with 3g.

Okay...so here's some more info. If I keep the logitech ps3 mediaboard keyboard active by moving the mouse or pressing the spacebar every 6 to 10 minutes or so the media continues to play. So it seems that when the keyboard goes into power save mode and disconnects it causes the media...ie: movie, show, or flash video to restart or exit. Does anyone else with an HDMI dock experience this problem? Videos play fine without interruption so long as bluetooth is disabled.
For those of you who aren't experiencing this issue, what brand/type of bluetooth keyboard are you using?

Okay, well it looks like I'm chatting with myself but oh well. Here's another update. Even with keeping the keyboard active through clicks or mouse movements streaming media will still restart after a given time. Usually around 10 minutes or so. Keep in mind that I have now found that it seems to only affect streaming media. Media that's on the tab plays fine with the only interruption being a brief image flicker when the bluetooth keyboard goes to power save mode. I would also like to reiterate that leaving bluetooth active on the tab does not cause any problem, streaming or not. The issues I experience only happen when the logitech mediaboard is on.
I'm hoping that the issue here is with the keyboard alone and not with tab's bluetooth program. To test out this theory I went ahead and purchased another bluetooth keyboard. I found a logitech dinovo mini on ebay for $62 with free shipping. If nothing else, the form factor of the dinovo mini is pretty cool and it has good reviews. Wish me luck with this new keyboard. I'll give an update when I receive and test out the device.

I use the apple mini keyboard, but not tge cradle. I might try it tomorrow. Good luck with the new one.

I got my Dinovo Mini in the mail this morning. It works flawlessly. No more restarts on my media!!! Very nice compact little unit. The only thing it is missing as far as the tab is concerned is a home button. Other than that, a purchase well worth the $62 bucks IMO.
P.S. --> If anyone knows what combo buttons you have to press to simulate a home button please let me know.

HDMI - Flickers
Muh
I have also problems with the Media-Dock and HDMI on my Flatsceen TV.
I'm currently using PDA: JMK.
(Firmware 2.2 / Kernel: 2.6.32.9 / Build: FROYO.XWJMK)
The Error:
The Handshake betwen the Galaxy Tab and the TV looks like it works well. After a couple of seconds I get a perfect picture with Sound. But after 5 seconds the picture disapers. 2 Seconds later it comes back for 1 second, and disapears again. The picture the starts to flicker ... comes, goes, comes, goes ... sometimes I see then snow for a second, then comes the picture back and disapears again ...
What I think what could be the Problem:
I think it could be a problem with HDCP.
What I tested:
I connected the Galaxy Tab with the same cable to a PC-Screen. Perfect picture, no problems!
About the TV:
I tried all HDMI-Ins. Including the one that is special for connecting a PC to the TV. I have no problems with my T-Online Media Resiver (Entertain) connected to my TV over HDMI. And I'm shure that HDCP is used with the T-Online Media Resiver.
Does any one have an Idea how to fix the Problem?
Greetings,

I had an issue with the picture going in and out as well. For me the problem was I was low on charge and I had the dock powered by a non stock charger which only trickle charged at most so the picture would keep cutting out every time it told that I was low on battery. This doesnt come up until you get around 10% remaining. That was solved by using the stock charger. The only other time I had an issue is when the tab is not secure in the cradle which was remedied by disconnecting it and then re-inserting it back into the dock.
Hope that helps.

Sorry for posting this in this thread.
But, it would interest me if the HDMI-Dock really needs a USB-power-cable plugged into it to work?

Muh
Yes, the dock needs power to use the HDMI out . . .
My problem for shure does not be casted by power problems. Im getting more and more shure that I have a compatibility problem betwen the Tab and the Toshiba TV.
I will now search in HiFi forums for a fix, and inform you when I figured out something. May be a older firmware could fix it to . . .

i cant understand why it needs a usb power cable for hdmi out?
is this really needed technically for it to work?
or is it just, idk to pester us?
because ipad also just has a hdmi adapter thing, where the usb cable is only optional.

I dont know, but without power you will not get any signal . . . I think the dock needs the power . . .
And i can not find any help for my problem in the web. It looks like i am the only one who has this problem.
But I figured out now that the tab is using 1024i as resolution . . . Does any one know if there is a way to switch the output resolutin of the hdmi?
Sent from my GT-P1000 using Tapatalk

no the tab upscales to 1080p.
there are sometimes problems with tvs that arent fullhd. it has to be fulllhd and not hdready or something inbetween, otherwise there might be problems.

The dock needs a power cube to work. Without one it won't function. However you can use a non stock power supply but you'll end up running down the power, albeit more slowly. Why this is a necessity I'm not sure. I think for the majority of the time you would want to otherwise it will run down the juice pretty quickly since the screen stays on while outputting to the TV.
It is best to have a TV that is full 1080p. My 6 yr old TV is only 1080i but it still works. Others may have varying results.
It would be nice to have a standalone HDMI cable similar to the AV cable but I haven't seen anything like that yet.

In other teste of the docking i did also read 1024i, and thats exactly as what it has been identified by mx tv. My tv can do 1080d, that can not be the problem . . .
May be you can double check as what you tv identifies the signal?
Do you think it coulf be a idea to try an older firmware? Any known changes in the hdmi out in the firmware versions?
Sent from my GT-P1000 using Tapatalk

Ok, i know now where my problem comes from . . .
The tab realy sends 1080p, but my tv can only do 1080i. :O
Any chance to set the tab to a lower resolution for the hdmi out?
When i connect the tab to a hdmi - vga converter i will lose Audio? Right?
(the tv has a vga in)

VGA:
picture quality loss (like from DVI -> VGA)
no audio support
but its still better than cinch

HDMI + Gingerbread = No GPS

Here's an interesting problem: Using an hdmi dock with an hdmi cable on the newest Sprint Gingerbread rom seems to kill GPS. When I bring up Google Maps it just can't find the satellites.
I don't know if the rom has anything to do with it but I do know that this rom acts with a different set of rules than the previous ones.
If I use the dock with the 3.5mm audio out and unplug the hdmi cable it works fine.
I know I'm probably the only person the planet that uses a Tab this way but if anyone has gotten this configuration to work please let me know so I know that I'm not crazy.
thanks

Mine works fine.

I have the same problem as you with HTC Sensation. Did you found the solution?

Not really. I have a theory that connecting the HDMI out is unbalancing the GPS antenna. I might start cutting wires and isolating the ground but I haven't gotten around to it yet.

Well I've tried a new hdmi dock, 2 different hdmi receivers, and even a galaxy tab 7.0 plus. It seems to be endemic to Samsung's hardware.

As far as I remember (I use CM7, not stock) you have to enable TV Out in Settings->Display (or somewhere in Settings )

CM7 doesnt support tv out. only stock rom or custome rom support tv out. just try randomly like this :
y-y
r-r
w-w
try:
y-r
r-y
w-w
or:
y-w
r-r
w-y
If i helped, dont forget to press "thanx"

TV-out has always worked for me on stock/custom ROMs. I use the Nokia 3.5mm to RCA cable from my N85.
Make sure TV-out isn't on, if it is turn it off and reboot. Turn it on after reboot and plug it in to the TV.
This method always works for me. It's also a good idea to turn screen brightness down to the lowest setting to preserve the battery.

HDMI vs. Wi-Fi Speed

Hello guys,
I'm experiencing a problem which is NOT good.
I have netflix on my LG P990 and on my PS3. Somedays ago, I've noticed that netflix was kinda lag but only on P990. So I decided to check this out.
The problem has been found: When I connect a HDMI cable to my TV and to LG P990, the wi-fi connection speed drops a LOT. I've been testing with Solid Explorer to check the transfer rate.
With NO HDMI cable connected, I got around 1.5MB/s, at the exactly moment I plug the HDMI cable, it reduces to 200KB/s or less. Sometimes it stops the transfer.
Then, when I unpplug the cable, it starts to go faster again! I've already tested 3 different ROMs: MIUI, CM7 Official and NovaHD ICS (all with FULL wipe) and the problem has been detected on all of 3 ROMs.
Is there anything I can do to solve this problem? I really like Netflix, and would like to use it on my P990 on HDMI cable.
Thank you guys!

did you try another HDMI cable?

Not yet. I will try to get another cable with my cousin to check this out. BUT, I don't think it's the cable. Thanks for you answer.

May I suggest you try this on the official LG 2.3.4 rom too? With full wipe of course.

Could be a bandwidth issues but i think its probably a poor cable.

..
How did you get netflix working with nova hd? I've never managed to get it to work on current ics roms !

Yes, I did. Tested today and got the same problem. I tested with an original SonyEricsson's Micro HDMI cable from a Xperia, and got the same.
Already tested it on another TV with HDMI and got the same.

I don't know how to get it back (and I don't think it's good ideia to go back to Stock ROM, cause this ROM is really slow )
Are there any other options?

I'm pretty sure it's not a bandwith problem. I started a file transfer without HDMI cable connected and got 1.5~1.7MB/s. From the moment I connect the HDMI, after 3 seconds, It's already in 40KB/s and then I unplugged the cable, got 1.5~1.7MB/s again.

I don't have it on Nova HD. I mentioned nova HD beacause I used it to test HDMI on Wi-FI. I use it on MIUI (GB) or CM Gingerbread ROMs

Hey guys,
after some Google search and reading a LOT of stuff, just figured out how to solve or at least get a better wi-fi speed when HDMI is connected.
I've read something about router's configuration on wireless settings could be possibly wrong.
I just logged into my router and chaged the wireless channel from 7 to 1 and eureka! Got it now. Just watched a netflix video without lag and in HD.
Seems HDMI connection when on, still causes some interference on wi-fi, but it's MUCH better now.
Tested with some file transfers as well, and got almost the same speed as without the HDMI connected. Sometimes I get the same speed on both cases.
If I have enough time on these days, I'll test with different channels.
Ps.: Channel 1 worked for me but maybe it's just on my case. Possibly you will have to check different channels on your network.

It's p990 hardware problem
if you plugged HDMI cable and connected to TV, WiFi speed drops very low almost zero
but sometime it works just fine, most of time not,
confirmed this on stock rom and CM7
using CM10 now, haven't tried yet, I think it would be the same.

[Q] MHL Issue on unofficial CM11

Hi there,
im having a big problem with MHL on my P880. Once i connect the phone, it simply does nothing. It only charges the battery. The TV recognizes the HDMI-Port i plugged the MHL cable into, but when i change the source to it, it only shows "No Signal".
I've plugged the HDMI into TV, the Micro-USB into the Phone, and the USB into a power source.
But there is no "Media Home" popping up on the P880... nothing
Using the Unofficial CM11 (http://forum.xda-developers.com/showthread.php?t=2551006).
Also flashed everything again, with full wipe and so on...
This is the MHL-Cable i'm using:

Same problem with same cable and other roms based on the same sources.
The only way to get it work is to flash iodak kernel 9.95 on top of the rom, mhl will work with rotation ok but after the screen turns off you won't be able to turn it on again until reboot.

flashed that kernel now... tried all HDMI ports, even tried on another TV... but still the same issue :crying:
it seems that may: i have to activate MHL anywhere in Android, the cable isn't working or the kernel is still the troublemaker...
So if MHL would work here, the "Media Home" process should pop up. Am i able to force-start that process anywhere?
Does anyone know whats the deal and how to fix it?

Try another rom first to be sure that it isn't a cable issue

just tried Omni, but nothing...
i've tested a galaxy s2 yesterday, and there the cable worked like a charm... I even think now that its a hardware issue on my p880. (may the MHL-chip be broken or so).
Should i try another cable then?

Try stock.
