So i just bought this monitor as I wanted to try 240hz gaming on my 2080 Ti. It ran good for a few games of Apex Legends and then just went full white. It flickered a few times and then stayed white. The game was still working however and my character in game was moving and I could hear the game and discord etc. Turning the monitor on and off didn't solve the issue but turning it off and then unplugging and plugging in the power cable worked. However after a few more seconds it happened again. After it happened the 3rd time I turned off G-sync and it stopped working. I obviously bought this monitor as 240fps is quite difficult to keep in most games at all times and I wanted the g-sync to avoid tearing so I can't just have it off.
What's causing this? I used DDU to clean install the latest drivers and am using a certified DP cable.
