Hi I have a problem with my sapphire pulse rx 580 4gb. When I play Fortnite or any other game that is heavy at some point my pc just stops producing picture on my Tv (1080p 60hz) I cant move in the game but I can hear my friends talking and they can hear me back only thing I can do is reset my pc and it gets really annoying and gfx sound like its gonna fly. I tried increasing the power limit meter for 10 I tried adjusting fan speed but it doesnt work. The problem appears when I play Fortnite, Assassins creed Odyssey and CoD Warzone. Its connected with HDMI cable. Now is it because its overheating (it goes up to 78C) or because of cable because the pc was connected to a 75hz monitor with display port and I have latest drivers installed.
