I'm not sure how to decode it because it's not publicly documented, but just by looking at it, it seems to be the same format as the TV resolutions data block. If that's the case, it has 3840x2160 @ 50/60 Hz and 4096x2160 @ 50/60 Hz. If that's the only way to add 3840x2160 @ 60 Hz with HDMI 2.0, then I don't know how to mark it as recommended. -- Edit: I just found some information that suggests the data block is for YCbCr 4:2:0 resolutions. If that's the case, then the TV does not actually support HDMI 2.0 data rates. What you can try instead is setting the first detailed resolution to 3840x2160 @ 30 Hz. Then hopefully GPU scaling will work with all the other refresh rates. |
