Hi!
I just upgraded from 8.2.5 to 9.0.0 but I lost the option of 4K@60Hz resolution. 30Hz is the top now. It's a J4205-based HTPC with HDMI 2.0 and a proper cable, 4K@60Hz was working well with 8.2.5.
Also, my previously user 3D LUT color preferences files are not working, the screen goes blank when the 3D LUT is active.
Thank you for your help!
