Do you have to use that displaylink software with terrible framerate and latency compared to native?

I tried to get 3 monitors working on a work Mac with a new triple DisplayPort dock and had a terrible time, I went back to my Linux desktop since I can easily get smooth 165hz native performance on three monitors

I use a dual DisplayPort doc then connect one monitor directly. I'm running 2x 1440p and 1x 1440p ultrawide this way. This is a work setup, so I don't really need massive performance. It's all 60hz and no noticeable latency.

I don't believe that triple DisplayPort works well with mac. I believe two is the limit.

I have a 4K monitor connected via usb3 displaylink and it gets 60fps.

Yeah, the key here is you must use a DisplayLink adapter. Most laptops other than Apple MacBook Airs don’t need this to have more than one extra monitor.

But they cannot last 20h on a battery, win some, lose some

i find the latency is pretty bad even though it’s 60fps
