Resolution change?

OK. I see no change, but the kernel seems more recent:

osmc@osmc:~$ uname -a
Linux osmc 3.14.29-30-osmc #1 SMP Sun Aug 13 13:09:05 UTC 2017 aarch64 GNU/Linux

It still says “Wrong signal frequency” when booting and no 1360x768 available under system settings.

osmc@osmc:~$ cat /sys/devices/virtual/amhdmitx/amhdmitx0/disp_cap
480p60hz
576p50hz
720p60hz
1080i60hz
720p50hz
1080i50hz

Yes – that’s correct. I didn’t bump the kernel version so that you will be on the latest kernel when the next update is released.

That can be fixed easily enough by forcing a default mode.
But first I would like to get 1360x768p working so that we can
force it to that.

Can you post your EDID for me? You can get this by running this
command:

cat /sys/class/amhdmitx/amhdmitx0/rawedid

Hello Anders,

Thanks for your patience while I looked in this.

I’ve reworked the patch and now added support for:

  • 640x480p60
  • 800x600p60
  • 800x480p60
  • 1024x600p60
  • 1024x768p60
  • 1280x1024p60
  • 1360x768p60
  • 1366x768p60
  • 1440x900p60
  • 1600x900p60
  • 1680x1050p60
  • 1920x1200p60

I’m not quit sure is 1366x768p60 will work; but 1360x768p60 should.

I can now set 1360x768p60hz by doing:

echo 1360x768p60hz > /sys/class/display/mode

But I think some Kodi changes are necessary for the new mode to be detected.

You can upgrade your kernel to this version by following the instructions above again.

Sam

Thanks. Will test over the weekend.

Thanks. We plan to release the next update on Sunday, so any improvements needed to Kodi to support this resolution will need to wait until the next update.

OK. I prefer this without the reboot, just so that you see any errors.

Tested echo 1360x768p60hz > /sys/class/display/mode and got a “Wrong signal frequency”

You need to reboot after installing the new kernel. I put && reboot, so reboot would only occur if the return code for apt-get dist-upgrade was not an error

I rebooted manually.

You forgot 1280x768

I’ve yet to find a display that actually handles this without scaling tricks
For such a display, set 720p, it will look fine.

Sam

But for mine, 1360x768p60hz should work, right? But it does not.

It should. I only get a green screen on my projector when I try this video mode; and I’m starting to suspect that this is why AMLogic removed support for these video modes from the kernel. It all seems a little hacky; as the VIC mode is internally set to 0 when a VESA mode is active. This might confuse Kodi.

I will revisit this after Sunday’s update.

Sam

1280x720 will 100% not work on my TV. I have tried with every device I own. The maximum supported resolution is 1280x768.

I used to have access to native panel resolution of 1024x768 this is now missing, but I am seeing other TV modes including 1080@24p which is nice. But native mode always looks a bit nicer… please re-add this. Thanks

It’s being worked on. So far the results have not been as promising as we would have liked but I will keep you posted.

Sam

Thanks! Waiting with bated breath :slight_smile:

Any updates on this? Family has sortof gotten used to menus being halfway off screen, but I dread the day when I will have to act on a message whilst updating and I cannot see it…

AML added support for more VESA modes. So when we sync the kernel, we will have support for a lot more video modes in the near future

OK. Sounds promising. What is the timeframe?
