1- when playing surround with three 4:3 screens is it important which monitor u get to minimize the size of the edges as to have a nicer view of the game ?
Not really. Obviously smaller bezels are better, but your brain does a nice job of ignoring them. I game on three 21" CRTs with gigantic bezels; there are almost three inches between each screen and I don't have a problem with it. Simply put, the immersion of a wide image that fills your peripheral vision is enough to make the bezels not matter.
2- I have a 5 year old dell 2001fp (http://reviews.cnet.com/lcd-monitors/dell-ultrasharp-2001fp/4505-3174_7-30588561.html ) can that work if i buy 2 more of the same ?
Yes. However, that is a 1600x1200 monitor and the TripleHead
2Go can only output a max of 1280x1024 to each screen. Not only does that mean you might get a fuzzt image from pixel interpolation, but the aspect ratios of the monitor and the input res don't match (4:3 vs. 5:4) so there will be a slightly stretched image.
If you use SoftTH you can game at 4800x1200 and use three 1600x1200 monitors at their native resolution.
2- should the 4:3 screens be a specific size. In other words are 19" better than 20" or vis versa for what ever reason?
19" monitors with a native resolution of 1280x1024 are generally the best for use with the TripleHead
2Go because you get the highest resolution output while still using monitors at their native resolution.
3- can u do triplehead with 3 x 24 " widescreen ?
Yes. The Digital TripleHead
2Go offers a 3840x800 resolution. Note that this uses the proper 16:10 aspect ratio per screen, but is only a resolution of 1280x800 per screen versus the 1920x1200 native to a 24" monitor. There will be a lot of pixel interpolation.
4- when we see pics of surround games on this forum they are the " copy and paste " of the three screens put together, right ?
Nope. They are screenshots taken while games are running in triplehead resolutions.
5- is there a program that can run those 3 screen on one single large wide screen, for ex. a 37 in monitor like this

You don't need any program to do that. You can simply add a triplehead resolution as a custom resolution in Windows. For that "monitor" (that's not a monitor, it's a TV) the highest resolution you could use would be 1920x480, since the monitor's native res is 1920x1080. There would be black bars at the bottom and top of your screen. You wouldn't want to do this for any purpose other than testing.
On a real high-resolution large monitor, such as 30" LCDs with a native res of 2560x1600, you could try 2560x640, which is still not very good.
6- there is a new mod for crysis in the works called BFG ( or something like that ) which is a WWII game. If crysis can be played online with 3 screens, is it safe to presume that so will BFG ?
Yes. It is the game engine and its parameters that determine if a good triplehead experience is possible.
