I bought this RX 580 Red Devil, just hooked it onto my PC. So as I was looking for the driver online, the monitor switched to this weird green screen, but it did not freeze. I believe the GPU was still on low resolution, then I heard that "new device connected" sound like you know when you connect like a USB to your PC? That's when the GPU or monitor switches over to the higher resolution, then that's when it turned green. So is this kind of normal glitches sometime for detecting new GPU? I rebooted the PC and installed the GPU driver and everything's been great. Or the ultimate question is: defected GPU?
