Thanks for all the advice. Unfortunately I was not able fix it today, but did get somewhere. Apparently the monitor on the left side works. I like having the comp window on my right side monitor for preference but this does not work. I physically moved the Ultrasharp to the left side and it started to work, and now the right side monitor wont work, plays at 16-17 fps ram preview. I have tried also changing the display arrangement in system preferences but that doesn’t work.
If I physically move the ultra sharp back to the right side it stops playing back in realtime after a couple minutes.
This is the weirdest bug I have ever seen, and I doubt it could be a signal/cable issue. Maybe my computer just doesn’t like the right side monitor? I really don’t like having the comp view on my left side.
I’m very disappointed I can’t find a fix to this and what’s worse is that I fear this such a specific problem that there will never be a fix or solution.
