I just purchased Radeon RX 550 4GB GDDR5 DVI-D Dual Link, HDMI, DisplayPort and put it in PC running Ubuntu Mate 20.04. Connected to Samsung UJ59 monitor. Unfortunately I experience a monitor blackout every minute or so: after a second or 2 it goes back to normal and then after another minute blackout again. Is there anything I can do to address that?
