Can you try unplugging the other output? Disconnecting the second monitor alone doesn't work, I was able to get it to work after disconnecting the second monitor and restarting then setting it to 240hz. I guess its as you say, a bandwidth limitation, i'm running an RX580 on the PCIE16X_3 slot on the asus x570 dark hero which for some odd reason defaults to x4 according to the bios. -- You are receiving this mail because: You are watching all bug changes.
