[quote]But can't you get around the scaling in windows and for other text-heavy applications rather easily by using just two 24" screens via the TH2Go and the third 24" connected to the secondary output of your graphics card?
Obviously this wouldn't work for games or higher resolutions than (2+1)*1920*1200, but then again in games the scaling isn't really an issue.
The way DirectX and OpenGL work, it can't be done like that. The operating system needs to see the whole area as one virtual display, not multiple displays for 3D fullscreen hardware accelerated gaming to work. There would be no need for any TH2G or DH2G product if it worked across multiple displays natively.
You can do 4 1920x1200 displays in 3D, but it requires 2 DH2G Digital and XP span mode. There is a thread about my experience with this in the surround-screen sub-forums here. Can't do 3 1920x1200 unless you use SoftTH though.
I think there might have been a misunderstanding.
I meant to suggest (and cleverly package this suggestion as a question), that one might be able to switch between 2*1920*1200 (via TH2Go and DVI Port 1 of the graphics card) + 1920*1200 (DVI Port 2 of the graphics card) for windows/work and 3*1680*1050@57hz (or lower) for gaming.
In theory I would think that this should work, by connecting all 3 screens via DVI Ports to the TH2G, and one of the three monitors additionally via either a secondary dvi port on the screen or via dvi->vga or just vga (if the graphics cards offers dvi & vga ports) directly to the graphics card.
If my theory holds ground you would just have to switch around in the Matrox Powerdesk and the input signal on one of the monitors.
So you could use windows on the native resolution of all three screens and games could be upscaled by the screens.
That post certainly exceeded my weekly quota of using the word "screen". ;)
