I am using RX 570. The image is sometimes black. Sometimes lines appear. Sometimes it breaks down completely
I uninstalled the driver with DDU but it didn't work. I installed different drivers, still didn't work
Does it happens only inside Windows or even during boot or at BIOS screen?Hook your pc to a TV or other monitor, it looks like a monitor problem or even try another cable.
If its not, then you could have a faulty card. Good Luck
