Hi I have a 2020 Macbook Pro 13" 2.0 Ghz Quad Core running Big Sur and hooked up, through a dock, to an HDMI input into a monitor. I have a gaming PC that I have hooked into the same monitor through a display port connection. The monitor has two HDMI inputs and one DisplayPort input. Anyway, when I switch inputs on the monitor from my MacBook to the PC, and then back, the MacBook always acts up--it either is no longer sending a signal to the display, or the display gets highly pixelated or otherwise messed up visually. I usually have to restart the MacBook to get the MacBook and display back in sync.
I never had this problem with my mid-2012 MacBook Pro 13" when I had it hooked into the display via HDMI, had my work PC hooked in through the DVI or whatever input, and then switched back and forth between screens.
Anyone know what could be going wrong? The MacBook has a thunderbolt 3 cable going from the MacBook to a dock, and the dock has a an HDMI output that is running to the display. Would it make any difference if I got a Thunderbolt 3 to HDMI cable and ran it to the monitor without a dock? Thanks--I don't imagine this is an issue a lot of people will enounter. I'm sort of spoiled that I have a killer gaming PC and a MacBook. First world problem, I know.
