Question display problems

Dec 27, 2020
hi i just recently built my 1st gaming pc and it works great its quiete puts out great frames but the only problem i have is sometimes my monitor turns off and on randomly only in game never outside if one.
i have already tried uninstalling and re-installing my drivers i have tried unplugging the monitor and plugging it back in i tried turning on v-sync and matching it to my fps aaaaand nothing works so i dont really know what to do anymore, there is also some screen tearing (with v-sync on) but i think i can fix that by getting a dvi display port.
The conclusion, or guess that ive came to is my monitor is bottle necking my pc’s fps so it turns off from some sort of over working but i dont know please try to answer me before i go buy a 240hz monitor..

monitor: asus 144hz 27” 1080p
