Thought I'd share my experiences in using DisplayLink as an user that uses multiple monitors (4 currently)
So I used to own an intel 2019 MBP 16" running off an razor CoreX eGPU on 5 displays (Four 27" 4k, One 27" 2k) off one thunderbolt cable, until recently the logic board died (suspect constant overload off one thunderbolt port).
I've been resisting to upgrade to an apple silicon Mac despite major performance upgrades due to the fact that the GPU options are pretty much nonexistent. Since my old MBP died I decided to upgrade to the m2 max 16" MBP that technically allows up to 4 external displays, but also means I need to have the hassle of connecting every single port available on the laptop.
That's until I learned about DisplayLink on external docs, and doing some research I found a dock that supports up to four 4k monitors @ 60hz (
wavlink UG69PD10 ) and I believe that is one of the few docks that could support so many monitors at once.
I'm usually a bit skeptical when I see such features without the need for an external GPU (mostly relies on USB compression I read), I've decided to still take the plunge and got one because I really prefer having as little physical connections to the MBP as possible as I bring my laptop around a lot.
I was quite impressed by how it was able to actually support four 4k monitors running at 60hz, but after a few minutes of using it you will start to realise the graphics is not as smooth as had you natively use apple's gpu. It's advertised at 60hz but it feels like it runs a bit lower than that.
I don't do much gaming so this really isn't too big of a problem for me, until I start to realise my computer temperature starts to run unusually higher compared to before (usually around 69-78 degrees celisus; when all four computers were plugged into the dock off one single usb-c cable to my mbp, my computer temp ran between 80-93 degrees celsius). Quite evident that DisplayLink is putting a lot of strain onto my CPU (especially running four 4k displays) and although I haven't feel any forms of thermal throttling I have concerns about using this setup for prolong periods of time under such stress. I was able to keep the temperature back down when I disconnect three monitors off the dock (reconnecting back onto the MBP directly), however you still see the slight lag when using DisplayLink off 1 monitor.
I've been trying to find more user experiences with DisplayLink online but couldn't find much at all. I'm most likely thinking about switching back to a standard thunderbolt 4 dock that will just utilise apple's gpu to power my monitors.
