Sounds almost unbelievable. I can't VNC into my Mac on my LAN without considerable lag. How are you doing that with 4k?

We have a dummy hdmi plug connected to each Mac. That will make macOS think that there’s a screen connected which enables GPU hardware acceleration.

But that’s what I was saying originally —- I’ve heard about this trick of connecting a monitor to improve performance but I’ve never seen it make a difference. Is there something else you have to do?

[rootdevelop]

I personally use Remotix for VNC, Remotix has integrated the Apple specific VNC protocol which allows for more performance, file transfers, etc.

Never heard of that client or Apple's proprietary VNC protocol (sounds like something they'd do). Thanks.

Ahh, I have been using Remmina. Thanks.

What bandwidth/latency are required for responsive interface?

[rootdevelop]

Anything above 20mbit should be fine

Thank you!

Are you using the built-in macOS client? macOS screen sharing has some VNC extensions that make it usable on both wireless and WAN networks. I've been VNC'ing to my 2560x1080 work machine from home for years through a layer 2 UDP OpenVPN tunnel over WAN to great effect (connect to OpenVPN, cmd+K in Finder then vnc://10.20.30.40/). Using the now defunct Back to my Mac always was a crapshoot though (probably due to lack of port opening, therefore an intermediary has to be used)

[copperx]

Is there any Linux client that implements these extensions?
