Hi, I just want to know whether my XFX RX 550 4GB GPU supports 4K 60fps on Ubuntu 19.04. Right now the maximum refresh rate I can set is 30hz (on 4K resolution), and if I go beyond that (to 60hz), the screen goes blank with no countdown to reverse the setting, then I have to force restart my PC.
I'm using built-in driver from the OS as official AMD driver only supports Ubuntu 18.04.
Please help, thanks in advance.
