Hi,
I recently bought this monitor and I also bought displayport cable to connect it to my PC and use free sync (g sync) option. I have GTX 1660Ti.
My problem is that when I connected monitor to my PC(graphics card) with displayport and I run a game with higher fps in full screen mode after few seconds monitor starts to lose signal. I'm not sure if it's losing signal but that's my guess. It acts like I would plug and unplug it every few seconds. It stops displaying anything, goes black and after few seconds it comes back for few seconds and then again black. For example I started League of Legends, it has around 200fps and it has this problem. In CS:GO there is no problem and it does not disconnect as I described above. In Escape from Tarkov it did not let me go in the menu as it started shutting down right away on the loading screen. In League of Legends when I switched to borderless instead of full screen problem disappeared. Red Dead Online works just fine, no disconnects. But it happened that it also disconnected like this while browsing the internet or on desktop. I also capped fps rate to max 144 in nvidia settings so it does not go above but problem is still there. I switched to HDMI cable and everything works fine, no disconnects but of course I am not able to use free sync option. What could be the problem and can I fix it with some monitor settings or graphics settings? Displayport cable is new, I plugged it in both displayports in graphics card but it does not change anything. Can anybody support me with this? Sorry for long question but I wanted to describe the issue the best I could so maybe somebody will help me find the fix for it. Thank you.
