I have a 75in hisense tv for my main monitor and a 55in onn as my side monitor for mt computer. Lately I have been having problems when I stream shows from my computer watching them on my TV. With out fail, the first time after startup that I start a show, regardless of the streaming service, my screen will go black for a few seconds and then come back. When it comes back, sometimes nothing changes, sometimes display settings are changed, sometimes it causes my computer to bluescreen! It has changed which monitor is main, the scaling percent, even sound output settings!
I used to have a 65in tcl roku tv as my main and I had to remove it because the screen would repeatedly go black for a few seconds, flash the desktop for a moment, and then go back to black. I thought it was my graphics card for the longest time and has pulled it out to send in, so I had my laptop hooked up the the tv instead, and it still did it!
I am at my wits end. Does anyone have any advice?
