Small correction; it’s DisplayLink, not DisplayPort. You have to use DisplayLink because they do some part in software as a part of their driver (which you must download and install) whereas the native Apple stuff has some internal hardware limitation.

I run three 1080p monitors off of my M1Pro, and I don’t notice any heavy CPU load from whatever software load the driver may be adding.

Displaylink is lossy software compression of your video stream, and when I last explored using it with Macs in a professional setting ~3 years ago the software was borderline unsupported by the vendor on the Mac platform and absolutely unreliable.

Thanks, staticfloat and ksala_!

DisplayLink*

I don't have any personal preference (I'm fine with a big single monitor/ultrawide) but from reading around and listening to other experience you're likely to hit performance/compatibility issues with that since it's a software solution.

Displaylink doesn't support hidpi monitors on macOS with fractional scaling (unless they fixed it in last month or so). For me this is a deal breaker since I have 27" 4k monitors which IMO work best at 125%-150% scaling
