When I play The Forest which I bought 2 days ago my monitor loses signal within 30 minutes of gameplay usually much faster maybe 5-10 mins. The sound still works just the screen is blank. If I turn off and on the monitor it displays ACER, but then it says again "no signal" and it's blank again. I have to hard restart the PC. Sometimes the fans speed up too, but not always. The temperature of GPU while playing is not more than 70C, CPU is even less. I cleaned the dust in PC, updated Windows 10 and drivers. I also tried playing Insurgency and Unturned, in these 2 games I havent had this problem, strange. I was playing on same resolution and good graphics and monitor didn't lose signal, but when I play The Forest it does. Some weeks ago I played ARK survival evolved and I think the monitor did turn off. I don't understand, some games work, some don't, I will try playing few other games to see if they work. Cpu i5, gpu nvidia 1060, 8gb ram, win10.
