Ubuntu 20.04.2 does not recognize 4k resolution on Samsung 28″ 4K UE590 monitor.
The monitor has the HDMI1 and HDMI2 input, the HDMI1 input ubuntu works 4k but with only 30fps, standard, as the manufacturer itself informs that it is a maximum of 30fps. On HDMI2 the manufacturer says it’s 60fps, but when I connect to the monitor on HDMI2 with a rx570 4gb, ubuntu does not recognize and only has a resolution of 720×480.
- Updated AMD drivers
- I configured it on xranr, without success
On Windows 4K works perfectly fine on HDMI2 which supports 60fps, but on ubuntu it doesn’t work!!!
Can someone help me?
