Synergy improved its interface in recent releases, but if you’ve tried Synergy on Windows and just couldn’t get it working the way you wanted, Multiplicity is a viable, if expensive, alternative. For $US30 it can control three PCs. For a whopping $US50, it works on up to six computers and can copy files and folders between PCs.
The takeaway: If Synergy isn’t working for you after following our guide, you’re only using Windows computers, and you don’t mind dropping a wad of cash, Multiplicity is a good option. For our part—we’ll stick with Synergy.

Saturday, June 18, 2011 at 8:25 PMlogmein is a rather different solution, aimed at remote access rather than treating multiple machines as a single display. I’m unaware of any features they offer that match, and I’m a paying customer.
Synergy is still the most flexible and reliable option, and you can do a surprising amount once you’ve worked out how to use their config files. a few years ago I had multiple laptops, and managed to get my desktop to recognise whichever one was on the network as the third screen on synergy.

Sunday, June 19, 2011 at 5:17 PMDoes anyone know if you can ‘sync’ or ‘gang’ multiple PC’s together. Essentially i want to run a Powerpoint presentation in 3 different cities, with the ability to show full res media (HD Clips etc), without the need to stream etc. By having the content local on each machine, all i need to do is control those PC’s in sync. Thanks!
