We have a client who has a machine using an extremely high resolution output setup (3 30" monitors in portrait mode for a total resolution of 4800×2560.)
He routinely remotes into this machine but the performance is lousy – we're looking for the highest fidelity remote desktop solution available for this. TeamViewer, GoToMeeting, and LogMeIn have proved inadequate.
Should we be looking into Citrix or something like that (none of us have any experience with it)? Basically what we need is the lowest-latency, highest performance app we can get. (The client realizes remote connections will never be up to speed but at the very least a reasonable amount of color fidelity would be nice.)
Bandwidth isn't currently a consideration here – we'll end up testing any solutions for real world performance but we really need to know where to look. I'm sure we can manage SOME kind of improvement.

RDP (Remote Desktop) is going to be significantly better than anything VNC-based, simply because of its architecture. RDP sends drawing commands instead of bitmaps, so it's much more efficient and responsive than just about anything except for Citrix.
Any remote desktop solution is extremely latency sensitive as well. Whatever you can do on that front can only help.
The only VNC variant I've seen that has much better performance than the rest of the pack is UltraVNC with the mirror driver installed. Once that's installed and configured correctly you'll get a good experience, but it still pales compared to RDP.
