Trying to force HDMI to mode 97 in config.txt with hdmi_group=1 hdmi_mode=97 doesn't work:

Code

tvservice -s
state 0xa [HDMI CUSTOM RGB lim unknown AR], 4096x2160 @ 30.00Hz, progressive

I've no idea what the issue is, but it's best to run the GUI at 1080p with 4K modes (23.976/24/50/59.94/60) in the whitelist for playback. RPi4 may be a leap forwards in terms of Pi hardware and processing but it's still a low-power ARM board.

Hi,

Im no expert but I manage to get 4K60fps on my RPI4 by :

- (obviously) Enabling the 4k60fps feature in config.txt : hdmi_enable_4kp60=1

- Using a HDMI 2.1 cable

- Enable HDMI UHD Color feature on my TV

The UHD Color feature was the last thing I did that finally resolve my problem.

Hope that helps.

"....GUI at 1080p with 4K modes (23.976/24/50/59.94/60) in the whitelist for playback...."

Do I need to touch "Resolution" or just go with the default and only change GUI and whitelist?

Thanks

**chewitt** · February 5, 2020 at 5:59 AM Official Post

"GUI at 1080p" means leave (or set) the default resolution to 1080p.

RPI4 only 4k@30hz: EDID shows 4k@60hz support but tvservice does not?
