External Monitor with M1 MBP Degrades Performance
Mac OS Montery 12.3.1
MacBook Pro 14inch 2021
Apple m1 Pro with 16GB
When connecting to external ASUS PA278CV monitor, performance in all versions of premiere pro suffers greatly. I have tested with another 27inch Dell monitor and seen the same degradation in performance. Lag and stutters on the most basic timeline with single 4k clips.
If you disconnect the usb-c connection, and run premiere pro then everything works fine.

Same here with the M1 Max 64gb

Same here with a Mac Studio. 64 gigs of ram 32 gig gpu. Premier runs flawlessly with hdmi monitor. Thunderbolt to display port result in the program being laggy. Clicking between project panels would take up to 2 seconds. Dragging clips in timeline is choppy and delayed.
