Partial flickering on external monitor
I'm using an external monitor with my 2016 MacBook Pro 15" and have noticed that a specific section of the screen will occasionally flicker and be darker than the rest of the screen for a moment. I've determined that it's not an issue with the monitor, as I've tried it on 4 different monitors and all have the same effect. I've been sending a signal to each of these monitors through USB C (not Thunderbolt 3) and have tried different ports and cables. I'm fairly certain that this is an issue with my MBP, but I have no idea what it could be.
These are photos I took of the flickers on two different monitors. The shape and location of the flickers appear to be the exact same.
