I just upgraded my aged gpu ( gtx 660 ) to ( rx 5600 xt ) to preform better with my 1080p monitor, the problem is that some games when i launch them my montior Enters power save mode cant do anything then but with restarting my pc . i noticed that all the games that didnt work were small n light games such as fall guys or among us only, other games works fine. And they worked fine with my old gpu and i dont really know what is the problem. sorry for bad English also idk much about hardware and thx .
