Ive been have a issues with my pc loosing signal to my monitor. I brought it into geek squad at bestbuy and the problem didn’t occur when they tried it and recommended just exchanging it so i did. The problem is still occurring when i just got a new monitor , the new pc i got new hdmi cord and it still looses signal and says no signal after a bit of me being on it. I have no idea why it’s still doing this problem and only way i found to fix it is to unplug my pc and plug it back in and it fixes the problem
