I have an ATI RAdion 9600 graphics card with the VGA o/p feeding my computer monitor and the DVI o/p feeding a Sharp LC26GA4E LCD display. The following comments refer to running the Sharp display at 1360 X 768 and 1280 X 768. When I select the DVI output as the primary display, my Nebula PCI card and DVD playback using PowerDVD work perfectly, both in window and full screen modes. If, however, I select the DVI output as the secondary display, the display is still good in a, say, half size window, but at maximised full screen I get a horizontally squashed 4:3, left justified picture. I am running Powerstrip, but I saw the effect before I installed that. Any clues?
