Hi all, recently got a asus pg278q 144hz gsync monitor from a friend and I plugged it in and enabled 144hz and it started to strobe (imgur: View: https://imgur.com/a/JImjjd2
) I currently have 3x 1.2 Display ports which I have tried on 3 different pc's and they had the flickering problem. Monitor works fine with 60hz, and does not seem to be gsync as when it is on or off it is still flashing. Do I need a display port 1.4?

Update: Monitor sometimes will flash its way to "no signal" and I will have to reconnect the DP cable. Does this confirm it is cable issue?
