Question about Sony VAIO VGN-A790 Notebook
HELP notebook screen went blank after installing a Samsung 245bw (dual display - XP) on a Sony VGN-A790, 17”, 1920x1200, ATI 600x (256MB) graphics card. Samsung 245bw (bad mistake) was replacing ViewSonic 21' (1600x1200) as dual monitor after the ViewSonic primary screen went out after 2 years.
I notice a difference in the setup of the two monitors, have you installed the correct driver for the new screen?
Try F8 on startup to get into safe mode, this should allow you to use the default VGA screen, and to reset the correct monitor drivers.
