Me, borned & raised in KK..
For 2d desktop use, or 3d app/movie watching
Matrox TH2Go supports only 3 monitors, DH2Go only 2
You have many options (Expensive to cheap) ..assuming 1 display is 1280x1024;1. 2x2 display or one 2560x2048 display in Windows....2 Matrox DH2Go and one Nvidia/ATI ..Quadro FX/FireGL with Genlock&FrameLock function... ...no problem with movie/2d/3d in all monitors. All analog solution(or mostly)
2. 4x1 displays...or one 5120x1024 display.. One TH2Go and one Nvidia/ATI ..Quadro FX/FireGL with Genlock&FrameLock function ...no problems with movie/2d/3d in all monitors. All analog solution
3....cheapest... 2x2 display or two 2560x1024 stacked or 4 individual 1280x1024 display in Windows.... Any 2 pci-e/agp/pci graphic cards. (but some graphic card dont play nice with each other).. (no problems in 2d.. movie only with selected players..like Apple quick time player) in all monitors...3d app only in the primary monitor. Best quality if you have 4 dvi output.
Ultramon software for desktop/wallpaper setting
Many other combinations.. for preview..please see my workstation setup (you tube) in Hardware Q&A
And for 10.8Mpixels displays
What model of nvidia card would you guys recommend, and also thanks for the info BeastX. Those were all the stuff I manage to get from the net from the past 1 week lol. It helped me confirm the stuff I found can be used, and including I could do it currently with my geforce 7300 LE for testing on two monitor.
