Intel NUC - Fail

Meh. Maybe i gotta upgrade *again*.

Solved it. Yeah, it's something related to 4K output. By going into Settings | Appearance and setting separate GUI and output resolutions LiveTV now works without stuttering.

I've set it to 3840x2160 for the GUI but 1920x1080 for output. Interestingly, if I select 1920x1080 for the GUI, LiveTV gives a blank screen. So it works but the switch from GUI to playback is slower now.

Still solved it. The GUI/Video setting helped with Live TV and 1080p content. But I got a black screen with my lower res video.

So I just forced X into 1080p instead of the auto-configured 4K resolution. Always a PITA finding the right modeline (X found like 6 or 8 different modelines.) But now LiveTV works, 1080p content works and lower res video works.

To put this thread to bed. I solved my problems by forcing X into 1920x1080. It's working great now, playing LiveTV, recordings and external video beautifully.

To be honest, I don't feel like I'm missing anything. I did some subjective tests with my family, playing a 4K video clip with the frontend in 4K. Then playing the same clip downsampled to 1080P. None of us could tell the difference. And this was on a big 82" TV.

Thanks for the thread - Also had the problem with my i7 NUC but now OK with separate video/gui resolutions.
As a matter of interest - What was the syntax of your config file to force X into 1920x1080 and where did you put it?
Running ubuntu 18.04 here.
I have the Device config as above in /etc/X11/xorg.conf.d/20-intel.conf which is detected and works OK.

I'm probably not the one to give advice on configuring X. However...

I put everything in /etc/X11/xorg.conf. The modeline goes into the "monitor" section:

Code: Select all

Modeline "1920x1080-60.0-1"  148.50  1920 2008 2052 2200  1080 1084 1089 1125 +hsync +vsync

But this is specific to my TV. You'll have to figure out your own. I extracted this from xorg.0.log. So nice that X now talks to your display and calculates these lines for you! Then in the "screen" section:

Code: Select all

SubSection "Display"
        Viewport   0 0
        Depth     24
        Modes "1920x1080-60.0-1"
EndSubSection
