Re: Nvidia + Matrox TripleHead2Go with resolution 5040x1050!
i seem to have the same issue with Vista 64, triplehead2go and three samsung monitors.
Everything works fine on Win xp using Nvidia 9600. Built a new machine using Vista 64, Core i7, MSI Nvidia 260, etc, and all monitors are showing 50 Hz and 48 Hz refresh rates. Samsung 226 BW and 225 BW sync ok (even with 48 Hz refresh rate). Samsung SyncMaster 2253BW sync's for about 60 seconds and then reverts to "Not Optimal Mode".
