Actually, the vertical resolution will be the same: the horizontal resolution is divided by 3 (for stripe configuration) or 2 (for delta configuration). Many of the high-resolution screens are delta configuration. That claim of 480 pixels vertically is intriguing: wonder what displays they're using?. A much better measure is the total display field of view (horizonatally and vertically) and the pixels-per-degree at the display center. These numbers actually reflect the resolution and immersiveness of the display. -------------------------------------------------------------------------- | My life is Hardware, | | | my destiny is Software, | Dave Stampe | | my CPU is Wetware... | | | Anybody got a SDB I can borrow? | dstamp@watserv1.uwaterloo.ca | __________________________________________________________________________
