Greetings. I'm running the following, wired as such:
Intel NUC NUC5CPYH (4K but 1080p preferred, latest firmware)
Pioneer VSX-1022-K receiver (1080p, latest firmware)
Hisense 50H8C (4K, latest firmware)
LE 7.0.3 installer: no issue
LE 7.0.3 operation: no issue
LE 8.0.1 installer: only the top-left quarter of the installer is visible
LE 8.0.1 operation (after bypassing receiver for installation): max resolution is 576p/50Hz, and only a few other resolutions are available
I've been able to find two workarounds so far:
Connect the NUC directly to the TV (which works great), pull the EDID info, and follow the wiki for using a custom EDID (Custom EDID - LibreELEC) after bring the receiver back into the mix. This seems to work well enough, but I can only pass through very basic AC3 or DTS, and lose most of the capabilities of my receiver.
Grab all the details of a working modeline at 1080p, and with the receiver in the mix, use xrandr to add the known-good modeline and then activate it. One of many downsides here is that I need to both set up the modeline and then choose it from the UI after each boot.
Is workaround B preferred, and is the right way to go about using that with a custom xorg.conf? Is there a minimal xorg.conf file I can use for just a custom modeline?
I had to revert the system to 7.0.3 for family use, so I don't have 8.0.1 logs available at present. I do have the Hisense EDID file as obtained from 8.0.1, and I can pull any info from the running 7.0.3 installation.
