Wrong display resolution passed to hyperion.

I have hyperion installed on my libreelec@amd64. It worked for me correctly through years, including Libreelec updates.

Unfortunately - something failed now. Hyperion reads output resolution wrongly.

Kodi side shows correct resolution: 1360x768. Unfortunately hyperion reads it wrongly - 3280x1080. There is completely no relationship between this value and hardware or any software. How to fix presenting resolution from LE/Kodi to hyperion?

As the effect - part of my LEDs do nothing.

I've found it!

The issue is outside of hyperion, kodi and libreelec. It's closer to hardware, some kind of hung up.

I completely forgot about one thing: few month ago I've connected HDMI wireless transmitter (with converter of course) to the second DisplayPort. From time to time I use FullHD projector with it.

So starting from this July I had:

- DP1 with 1360x768 TV

- DP2 with 1920x1080 transmitter

This worked great till now and without any reason - failed. With completely no action performed, including any connections or turning projector on/off.

I've checked:

# xrandr

Screen 0: minimum 320 x 200, **current 3280 x 1080**, maximum 16384 x 16384

DisplayPort-0 connected **primary** **1360x768+0+0** (normal left inverted right x axis y axis) 1600mm x 900mm

1360x768 60.02*+

[...]

DisplayPort-1 connected **1920x1080+1360+0** (normal left inverted right x axis y axis) 708mm x 398mm

1920x1080 60.00*+ 50.00 59.94 30.00 24.00 29.97 23.98

[...]

Looks like Screen 0 changed its primary display.

Now just disconnected transmitter and connected back and looks that DP-1 does not determine final resolution. I can see:

Screen 0: minimum 320 x 200, current **1360 x 768**, maximum 16384 x 16384

DisplayPort-0 connected **primary** **1360x768+0+0** (normal left inverted right x axis y axis) 1600mm x 900mm

1360x768 60.02*+

720x480 60.00 59.94

640x480 60.00 59.94

None is marked by star "*".

Probably I could fix my issue using command:

xrandr --output DisplayPort-0 --primary

I'll check it next time...

Now LEDs work fine
