I have an Odroid N2 connected via high speed HDMI to a 4k HDMI port on my Vizio P702ui-B3.
One of the sample files I am using is (UHD Samsung - Dubai File): https://www.demolandia.net/downloads.html?id=60876578
I have adjust refresh rate on start/stop enabled. Is there something I am missing?
This is the output from dispinfo: http://ix.io/2pqJ
Sounds to me like a misconfigured whitelist. Can you clear it?
Can you also give more info about the demo ypu are playing?
So looking at Settings>System>Display, there are various resolutions and refresh rates but the max resolution is 1080p. None of the resolutions are selected - is that what you mean by clearing it, or is there a file I can actually edit to remove the values?

I have also ordered the following HDMI cable:
You delete everything in whitelist.
@cdu13a Some of those Vizio TVs were tricky. I think this is a 2014 model, not HDMI 2.0, but it should support 4K @ 60Hz @ 4:2:0.
Can you take a look?
I tried loading the edid from that model vizio tv, and ended up with 4k playback when I tried to play that sample.
Do all 4k files end up playing back at 1080p or just certain ones?
Also you may need to enable the
Use 4:2:2 colour subsampling option in
Settings > System > CoreELEC
Otherwise the TVs 300mhz bandwidth limit could cause issues with playback of some files.
Ok, enabling 4:2:2 color sampling causes no signal when I try to play the video.
I only have this one mkv sample and a ts sample. Are there any particular containers or samples i should try?
Well, after two weeks the cable finally arrived and I am now getting 4K playback! Thanks for the help
