[Q] Dock video quality - G Tablet Q&A, Help & Troubleshooting

I've read all of hte dock threads, but can't find anyone that may have the same issue as I do.
Here's the history. I was running Calk/Clem, and could watch movies on my TV via the dock's HDMI connection. Everything looked brilliant, nice and crisp.
I decided to try out a HC rom, and went with Gtabcomb. I docked it and tried to watch a video, but the quality was pretty poor. it was pixelated extremely bad. The image on the tablet, though, was beautiful, comparitively.
Figuring that it might have something to do with the rom, and lack of acceleration, I decided to go back to a Froyo rom again. This time, I chose BC, which I had been on before, but didn't have the dock at the time. I, once again, docked it, and attempted to watch a movie, but it too was pixelated.
I flashed Clem's Kernel, thinking that it may have something to do with Pershoots Kernels (which are run on both BC and Gtabcomb) No go, still pixelated.
Wiped dalvik, wiped cache, wipe data/factory reset, reset permissions, repartitioned, flashed Calk/clem again, thinking it will be all right now, but nope, my videos still look perfectly fine on the gtablet, but are pixelated on the TV. They looked absolutely beautiful before, but not anymore. Even the home screens are pixelated, now.
I've tried Rockplayer (the original player when all was fine, software encoding, I get no sound when using hardware encoding) Moboplayer, stock movie player, "video player" that was in the Calk/Clem removed apps folder. Not one of them will play the videos properly on the TV, yet they look wonderful on the tablet itself.
Anyone have any ideas why my dock has started to transfer in a lower resolution than it had previously? I've changed no settings on my TV, and everything else plays fine through it (PC, WII, DVDs, Fios)

A few questions come to mind! Are you sure it's not the movies? Are you using anything different to encode the movies? At what resolution are you encoding the them?

---

I thought of that too. I don't actually encode any of them. I just ehem, <find> them online. Most are AVI movies. I still had one that I watched prior to the resolution messing up. It looked fine before, and doesn't now. Additionally, it's not just the videos, it's the home screen, the lock screen...everything is pixelated.
I was planning on editing the OP as well. I tried starting simple, and switched out the HDMI cable...It's not that, both cables lead to same results.
Could something have gone wacky with the dock itself, perhaps?

---

Does the TV detect the input (output from the dock) as 1080p? Have you tried manualy checking/switching display modes on the TV to see if any make a difference or maybe connecting to another TV.
Also. it is the Tegra2 that does the hardware upconvert from the native 1024x600 resolution to the 1080p (1920x1080) output. There are a couple of entries in build.prop that shouldn't change but you can take a look just to make sure...they are persist.tegra.dpy5.mode.width=1920 & persist.tegra.dpy5.mode.height=1080.

This happens to me using the HDMI cable for the gTablet. The homescreen is pixelated, movies are also but they are stil watchable. I've tried 2 tvs and same results on both.

just checked build.prop, and both of those lines exist...
edit: oh yeah, and I'm poor...only 1 TV available...I have tried changing TV settings with the same results, pixellation...I'm so confused. I wouldn't be surprised if it had been happening all along, but this is a new development, it's weird.

Try this, TJ:
Edit /system/lib/egl/egl.cfg to have these lines:
Code:
0 0 android
0 1 tegra

Use Android's software renderer then:
Code:
0 1 android
0 0 tegra
Then, try switching between the Tegra renderer and Android rendered for display 1 (display 0, I believe, is the tablet screen--display 1 might be the HDMI output):
Code:
1 0 android
1 1 tegra
and
Code:
1 1 android
1 0 tegra

Code:
0 1 android
0 0 tegra
didn't change anything
Code:
1 0 android
1 1 tegra
Lost visual at 3rd splash screen when rebooting...had to reflash rom to get it back
Code:
1 1 android
1 0 tegra
didn't attempt becuase of what happened above, lol
edit: Is there a chance that something is wrong within the dock itself? Just curious, as it seems that the tablet is functioning properly,as is the TV, and the HDMI cable...the only variable not questioned so far has been the dock itself...

Yeah, that was my screw-up. I was in a hurry yesterday and I didn't check. Try these settings:
Code:
0 0 android
0 1 tegra
1 0 android
1 1 tegra
It enables the tegra HW renderer (which is the only one available going by the libs in /system/lib/egl) for both the LCD and the dock.
And, you don't need to reflash the ROM, just create a file with "0 0 tegra" in it (the GtabComb default egl.cfg file) and adb push the file into /system/lib/egl/egl.cfg. That will stop the boot loop.

yeah, I've never done the ADB thing before, and I've honestly NEVER had any experience with anything Linux...so, trust me, reflashing was probably the easiest thing that I could do, lol
Edit:
so, in your previous post, should all 4 lines be in the file?

Yeah, give it a try. And, if that doesn't work, I give up and you'll have to seek a higher power.

I am an Elder at my church, you'd think that would give me some "pull," right?
edit: nope, it's a no go, and the big guy wasn't any help either....
thanks for trying, man. one of these days, I'l probably just end up seeing it work...

Also running Calk+Celmv6. Just got my dock in today. I believe that is just the way it is. Home screen & all non hardware accelerated video are very grainy. Viewed mine on a 42". May look better on a smaller TV but probably not a whole lot better. Colors are very overdriven compared to what shows on the gTab.
Watching Netflix was kind of like watching an old VHS that you had recorded from the TV.
Played a converted DVD through Rockplayer in both soft decode & hardware decode. Soft decode was grainy as well. Hardware decode looks MUCH better.
No problem with sound.
Didn't try Moboplayer since on my gTab doesn't play well with it...automatically reduces the volume to 50% and won't go any higher (even though it says it at 100%). I can verify this by exiting Moboplayer & turning up the volume which is at the 50% levelo

I get the same thing with mobo player and sound. With rockplayer, if I choose hardware decoding, I get no sound whatsoever, not just through the dock, but when run undocked, I don't get any sound at all.

I had some problems with the intial version of Rockplayer that was on v6, especially after I installed Remote Media Center (RMC). RMC said it only works with Mobo & Rock Lite so I downloaded Rockplayer Lite & it worked. The version of Lite was newer so I looked for newer version. Downloaded v1.7.2 and now no problems with rockplayer, even with RMC so uninstalled Lite.
