Display Port Lag

[anthlover]

You have non M1 mac that natively supports multiple external Displays over its 4 Thunderbolt3/USB-C connections.

I would use USB-C to Display port adapter or a Native Thunderbolt dock.

I have and really like the Targus 180 and a Caldigit mini thunderbolt 3 dock.
I have both an M1 MacBook Air 16/1TB and MacBook Pro 15

Note that Displaylink chipset /drivers for most DisplayLink powered docks rely on USB 3.2 Gen1 at 5Gbs versus Thunderbolt 3/4 native 40GBs.

I have no lag with video on my two monitors on either dock but my needs may be more modest then yours.

I suspect the issue your having is with the TT dock you bought being sketchy.

Thunderbolt docks and USB-C to display port adapters have no issue with rotation and require no drivers.

Good Luck.
