Westlake Village (CA) - Only large screens can take advantage of the pixel horsepower of quad-SLI systems today. But those 24" or 30" monitors are everything but cheap and may not be an option for every user who already paid more than $5000 for a computer. An alternative could be ABS Computer Technologies' triple screen solution based on the Matrox TripleHead2Go.
By combining the screen area of three 19" monitors, TripleHead2Go opens a spanned screen area of 3840 by 1024 pixels (almost 4 Mpixel!), which requires massive graphics processing power to enable a smooth gameplay experience. We recently visited the offices of ABS Computer Technologies, where James Lee and Samuel Gao demonstrated a triple monitor setup to us and explained the challenges of building a quad-SLI system.
Interview with ABS Computer Technologies - Triple monitors with quad-SLI (4:29 minutes)
There are two versions of the video interview. The first is H.264/AVC, which requires either a very powerful processor or a video card that accelerates H.264 playback. The second version is a lower resolution Windows Media Video and should play fine on most machines.
