Question Display shuts off when gaming, but not in stress tests ?

[Goga16]

Hello, i have this problem here... My display shuts off after 5-7 minutes of gaming. I ran a few stress tests (furmark, superposition benchmark); it ran for like 30 mins and nothing. Also stressed cpu and gpu both at same time, still didn't shut off the display. So, can yall help me? Any suggestions?
