why not 4k/60Hz on Mint 20 with Nvidia?
by Janus84 from LinuxQuestions.org on (#577HS)
I'm unable to output 4k/60 on new Mint machine with Nvidia Quadro P400
The best that I can set via GUI is 4k/30 and this works once out of 20 attempts (plugging / unplugging / rebooting)
I'd like to know if I'm wasting my time with this or should 4k/60 be achievable?
I've set the desired output manually via xrandr with no result..

I have ordered MiniDP to HDMI adapter just in case, currently using Belkin branded MiniDP to HDMI cable. The Quadro has only MiniDP ports, what are the best ways to hook up panel with HDMI?
