Jetson TK1 Android HDMI to DVI issue

Gopinath · April 6, 2016, 9:58am

Hi,

I am using Jetson TK1 for Android. I am facing an issue display resolution mismatch issue for HDMI to DVI. The below is the link for snapshot of the issue.

https://drive.google.com/open?id=0B4bn5jgyjOp6RFpyblFzVTAya00

Below are my observation on this issue.

It seems that 480P resolution is set by Android even though my monitor supports 1600 X 900
This issue occurring for all the same type of Monitor. (Here I am using Dell )
When I tested with another monitor (Acer) this issue is not occurring.
This issue is not happening in HDIM monitor. Only happening when using HDMI to DVI that too for certain monitors alone.
When I look into the log message using logcat it seems hwcomposer is setting the wrong resolution. See below for the log messsge.

So can you please explain me, why this issue is occurring and how to solve this issue?

Thanks

I’m not sure how to debug under Android, but the log obviously shows that EDID is being read…apparently the monitor is responding with modes it is capable of, but most of the modes are being rejected. This tends to validate that EDID is reading ok.

Sometimes cables have issues with causing EDID read failure for whatever reason…perhaps the monitor is newer and the DVI-HDMI adapter is older and the standards end up being insufficient for proper passing of EDID, but in general DVI is not an issue (cables do turn up as an issue at times, which includes DVI adapters). Because EDID was indirectly showing through the log that it was read, I doubt this is the problem.

In many cases the monitor itself will indicate compatibility with some modes which do not fit nicely onto the screen. When that happens the monitor works but some portion of an edge is clipped. I suspect that the mode you are looking at has that issue and that the monitor just does not work as an exact fit to that mode.

As to all of the other modes which were shown available but rejected I don’t know where to work on that. Possibly the kernel driver…I do not know much about Android.

Hi,

Thanks for the suggestion. Here are few other observations and updates.

We are using same kernel for both android and Linux Jetson TK1. The same monitor is working fine in Linux Jetson TK1. Its means kernel driver is supporting that monitor and resolution.
Also no issues with cable. Same cable working fine in other monitors.
The log messages are from hwcomposer (hwcomposer.tegra.so) it seems.
Also I am able set the kernel driver resolution manually to any value ( here 1600 X 900 @ 60P ). But even though the hwcomposer still in 640 x 480 @ 60.00 Hz. So output is not good.
Below are the different monitors working fine in Android.

Dell

Dell ST2420L
Dell E2214H

Acer
acer S220HQL
acer V203H
acer S240HL

So far Dell IN2030M is not working.

Does it means, hwcomposer.tegra.so is not supporting for this monitor? Also we don’t have source code for hwcomposer.tegra.so.

May be issues with hwcomposer.tegra.so ?

Regards,

Gopinath

hwcomposer.tegra.so is part of Android, and does not exist in L4T. So I assume source code for that is available via Android, and is consistent with the idea that this file is the issue since the monitor works outside of Android (e.g., L4T). It seems as though what you need is a debug version of that library, or at least a version with logging in which you can add logging statements to. I have no knowledge of how Android deals with graphics, e.g., compared to ordinary X11 on Linux, but I have to wonder about this as well because it is generally the graphics software which looks for and sets up for different video modes.

I am facing the same issue.

I have a HDMI monitor with 1920x1920 resolution and plug into Jetson TK1,
but when I run Android on Jetson TK1 the screen is output with 1920x1080 resolution.

I type adb logcat and see the hwcomposer log with edid info:

The log shows the monitor supports 1920x1920 resolution, but there is a “unmatched” log but I don’t understand what it means.

And there is another problem that the Android SurfaceFlinger only render the 1920x1080 buffer:

After I google this problem in the internet, I found a system property called “persist.sys.display.resolution” can adjust the SurfaceFlinger buffer size.

I set this property to 1920x1920 and rebuild and run Android. The logcat shows:

There still a problem is that hwcomposer still use 1920x1080 resolution output and the “unmatched” log still exist.

Does anyone know how to solve this problem ?
Is there have any system property I can set or any method I can try to adjust hwcomposer to output with right resolution ?

I saw this in another thread…but basically I wonder if 1920x1920 even exists…1920x1080 is valid, but to get 1920x1920 you need a custom monitor and custom edited EDID. Are you sure 1920x1920 is really the monitor’s resolution? Is this a special monitor of some sort?

Yes, it’s a special monitor and I can see the 1920x1920 option in the /sys/graphic/fbx/modes.

After I force change sysfs mode setting to 1920x1920 resolution, the monitor is change to 1920x1920 resolution but hwcomposer still render the buffer with 1920x1080 resolution.

Unfortunately I know far less about Android. One thing I’m wondering is if some of the modes are in software framebuffer only? Does the Android support installing of or query with the equivalent of “glxinfo”?
