UHD 620, 4K, 60Hz, RGB over HDMI

MartinT — Wed, 26 Aug 2020 15:28:59 GMT

Hey,

Is this combination possible? Lenovo T480s connected to a Samsung QB55R (only has DVI and HDMI). I can get 4k@60Hz using a USB-C to HDMI cable, but it's 4:2:2 (8 bit). I can also select 4k@30Hz and it's at 4:4:4 (8 bit).

I've been trying to get 4k@60Hz 4:4:4 but at this time wondering if that's even possible.

Slight bump. If someone could confirm if this chip can or cannot run 4K, 60Hz, RGB using a USB C to HDMI I would appreciate it.

One more bump to see if I can get confirmation about this chips capabilities.
