[CentOS] CentOS 7 and 4K display

I installed C7 along with MATE desktop...

My monitor is a 4K unit but when I goto the
System -> preferences -> hardware -> Displays
there is selection for the 4K display. It stops at 1920x1080.

The var log x file shows the 4K resolutions in the file so that is good.

How do I get the selections for 4K to show up?

Thanks,

Jerry

[CentOS] CentOS 7 and 4K display

Hi Jerry,

I believe there is no support for 4K in MATE yet, a nice problem to have though.

I'd check Gnome or KDE.

My monitor runs at 2560x1440 with Centos 7 and Mate.  I have to use the
displayport connection between the computer and the monitor to make it work,
though.

What is your graphics card model?

Which driver are you using?

What connector are you using (DVI, Display Port, HDMI)?

Does it work at 4k with Gnome, or KDE?

I would suggest trying the NVIDIA proprietary driver from the ELRepo

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

yum install kmod-nvidia

reboot

[CentOS] CentOS 7 and 4K display

On Windows (completely different software I know)
I've never been able to get 4K monitors to work
using HDMI 1.2. They always max out at 1080. Simply
using DisplayPort, everything else being equal,
fixes the problem. Same on Macs.
