It's a brand new Samsung Nu8500.
4K only works with no hdr, when I enable UHD color option the screen goes black (no signal)
Hdr only works on 1080p when I enable UHD color.
Here's what I tried:
1- disable hdcp (ps4 safe mode)
2- turn on hdcp only on 1.4 (ps4 safe mode)
3- turn on hdcp on automatic (ps4 safe mode)
4- turned on safe mode on ps4 pro and force 2160p yuv 420 resolution with hdcp on 1.4
5- turned on safe mode and force 2160p yuv 420 with hdcp on automatic
6- game mode on
7- game mode off
8- enabled UHD color on hdmi 1 to 4
9-tried a Belkin 2.1 hdmi cable (48gb)
10- tried on hdmi 1 to 4
I have no idea what else I could do.
