I recently got upgraded to a RX570 and everything worked finebut now my zowie XL2411P monitor gives a no signal message when i use a DP cable but when i plug in a HDMI it works again.
I've tried updating all the drivers uninstalling and reinstalling them. I tried different ports on the card and a different DP cable but nothing seems to work.
best would be to try HDMI or DP
DVI-D or DVI-I? also check your cable
