my friends monitor screen goes blank after 1-2 hours of use. I traded monitors with him and they both work perfectly, his monitor with my system and my monitor with his system. it only happens when he is using his monitor with his system. both systems run windows 10 and were built by me. my system is beefier than his. his drivers for his GPU and monitor are up to date.
