Question for 4K configuration according to Wiki

    Hi all,

    I have a two questions regarding the Wiki, specifically the 4K Configuration in LE as described here: https://wiki.libreelec.tv/configuration/4k-hdr

    I am currently configuring my LE 12.2.1 according to the points described on that page and noticed two things.

    1) For the 2nd point ("Mode Whitelist"), I noticed that some modes are listed twice. a) why is that? and b) shall I just select both in these cases?

    2) In the "Deinterlace" Section I want to remove the modes that are mentioned in that article. However, I cannot find the Deinterlace setting where I can do that. Can someone point me to the exact location for that setting?

    Many thanks!!

    I've no idea why those specific resolutions are duplicated in the selector on your system but there is presumably a difference other than the resolution that results in a different mode being listed. The display order in the GUI should be the same as the "Found resolution" data you can see in a kodi debug log (must be a debug log). You can also compare the output of "modetest" on the CLI to see what's listed there.

    NB: There is no separate deinterlace section. If there are 1080@25/29.97/30 modes in the whitelist deselect them. If none of those modes are selected .. don't select them.

    Thanks chewitt ! I still had a fairly recent debug log from a few days ago that was created with <setting id="debug.setextraloglevel">131072</setting> (due to a different issue that has been solved). This is the log.

    At the beginning of the log, I can see these resolutions (1920/1080 60Hz also shows twice):

    Not sure what I should make of that. I think I will simply select both values that are present in the selector...

    Thanks for the explaining the deinterlace topic - noted!

    The resolution list from kodi tends to be the list extracted from the edid, plus the mode kodi was launched in (internally denoted RES_DESKTOP). The latter of these shows as a duplicate.

    In some places (like setting the default resolution for the GUI) they behave differently. Consider choosing 1920x1080@60 vs RES_DESKTOP (which we'll assume was 1920x1080@60).

    e.g. if you connected to a different display that reported 1280x720@50 as it's preferred mode (but still supported 1920x1080@60) then choosing the former option would result in a 1920x1080@60 GUI resolution, whereas choosing the latter would result in 1280x720@50 GUI (this monitor's RES_DESKTOP).

    As kodi doesn't make it clear which is which in the GUI, this distinction is less useful.

    It would be better if in settings, RES_DESKTOP showed with a unique name (e.g. "DEFAULT").

    And it should probably be filtered out from whitelist.


    Your second duplicate resolution is probably the edid reporting two different modes with same refresh/timing, but some other differences (e.g. blanking period or aspect ratio).

    Code
    edid-decode /sys/devices/platform/axi/axi:gpu/drm/card?/card?-HDMI-A-1/edid

    may provide some clue.
