Problem

Symptoms: A user with a graphics card that supports 1024x768 16 color display manually selected the graphics driver that came with the card in WP 5.1. When the user went into View Document, the computer locked. The problem did not occur when the user auto-selected the graphics card (640x480 16 color) in WP. Solutions: The user rebooted the machine and discovered that the VGA card had only 256K of video memory. With 256K video memory, the highest 16 color resolution that a graphics card can display is 800x600 (which requires 234.4K). The 800x600 16 color driver worked fine. To display 1024x600 resolution at 16 colors, the graphics card must contain at least 384K video memory.

The following chart shows the relationships between resolution, colors, and memory for graphics cards.
