I forgot there are other commercial vnc products. TigerVNC is free and also cross-platform. For that matter RDP is more performant than vnc (ime) and viewable on open source vnc clients -- is that still free on Win 10/11?

Remote Desktop is free in Pro and server editions of Windows. That's what we used at work. 

It's quite something to see an ancient Dell C2D business SFF pc with Intel graphics driving Win10 to a 27" iMac display via RDP. Amazingly responsive.

I upgraded my home PC to from normal Win 10 to Win 10 Pro specifically so I can use RDP to log in to it from work to make it look as if I'm working when, actually, I'm pissing about on my home PC*.

I think it cost about £7 with an upgrade key acquired from eBay.


*in my defence, we've had fuck all work for months and, in fact, have now emptied our order book and are shutting up shop. It's been so long doing naff-all it's going to be a major shock to the system in three weeks when I start my new job!
