I have my computer connect to my roku tv(TCL). I've noticed sometimes when I'm just using the computer(most prominent in watching videos) that the roku tv's screen will just go black for 2-4 seconds and return to the computer. But it'll either strengthen the quality on the screen, or blur and slightly pixelate it. I've only changed a single setting since I got this TV, being turning on gaming mode. I recently added a monitor that's also connected to my pc but only the roku's screen goes black. And the monitor's quality remains the same, unlike the roku's. I haven't seen this happen on any other channel yet, but it's really concerning to me.
