No signal pop up after turning off for a while and trying to move my mouse

I recently bought a Samsung G6 G60Sf, it works great up until I leave for a while (maybe 30 minutes) and when I come back it won't turn back on. If I move my mouse it says no signal and turns back to black. The monitor is still on since I can use the OSD and other monitors don't have this issue with my PC. It only started happening recently after a few weeks with the monitor. Restarting my PC with the power button makes it work again, but I'm tired of restarting constantly whenever I leave to do something else. I'm connected with Displayport 1.4 since the monitor doesn't support 2.1.

Anyone have any solutions?
