Problem with the second screen not functioning.
Problem with the second screen not functioning.
Using your old RX 470 was fine, but after switching to an IGPU it stopped working. Now you're on an RX 570, though it doesn't cooperate—mirroring works in BIOS but Windows won't recognize the second screen. Could be driver issues or hardware mismatch.
The second screen supports DVI and VGA, while my 570 lacks VGA, leaving me with just DVI for use.
It seems like the problem might be related to the display driver or Windows itself.
