LE11 don't recognize all possible monitor (TV) resolutions

I'm wondering if there's a restriction on switching to something lower than the GUI resolution (1080p). The logs will show more I think.

Question Kodi GUI settings:

Kodi GUI Resolution

"The ideal setting is the highest resolution your hardware supports and/or what the TV/Monitor is capable of.

Be aware that reducing the resolution will pixelate the interface but it will not reduce the display size as the TV will always zoom the image to fill the screen."

My setting is 1080/50 but the WIKI recommendation is 4096x2160 @ 60Hz (highest supported resolution of my TV) or not?

1080@60 (and whitelists for 4K modes, as you've done) would be our recommendation. The skin is 720p or 1080p (not sure which) so the TV does a better job of scaling an already rendered image to 4K than Kodi does using CPU to scale the content to render. Few people have HTPC devices with the CPU to handle 4K GUI smoothly.

I have found the cause.

Whitelist function, here the function "Allow double refresh rates" was not activated.

Kodi will play at DVD 576/25 now 576/50.

Thanks a lot.

That's odd - you'd expect DVD native 576i25 MPEG2 video to be deinterlaced to 576p50 (as i25 = 50i and will have 50Hz motion if the source has native interlaced motion) and not need the double refresh-rate option (as DVD is MPEG2 576i25 which is a 50Hz not a 25Hz format).

You'd only expect that double refresh rate option to be needed for Handbrake or similar rips from DVD where the 576i25 MPEG2 has been converted with a deinterlace 576p25 h.264 or similar (which is fine for film-sourced content that is native p25, or p23.976/24 sped-up to p25 for 50Hz DVD), particularly as 576p25 isn't a valid output format for HDMI (HDMI only supports 576i25 and 576p50 - the two different 576 line 50Hz refresh rates)

Does LE default to a i25->p50 deinterlacing for interlaced i25 MPEG2 and h264 sources (like DVD, DVB 576i25 / 1080i25 etc.), or do you have to manually switch to a '2x' deinterlacer - I can't remember - but I thought it usually defaulted to a frame per field deinterlace?
