In other words, they take 2 displays and make them looks like 1 giant display to the operating system. So 2 1920x1200 displays would appear to be a single 3840x1200 display. This will give you the number of pixels that you expect, but your desktop environment is unlikely to play all that well with such a configuration. (If anyone knows of a device that doesn't operate this way, please let me know. I'll almost certainly buy a couple.) -- ======================================================================== Ian Pilcher arequipeno@gmail.com Sometimes there's nothing left to do but crash and burn...or die trying. ========================================================================
