Problem

Symptoms: When a customer using a NEC Multisync 4D monitor with a Video 7 VRAM card tries to select colors for the document screen, there are 16 choices for the foreground color, but only 8 choices for the background color. The customer would like to have 16 color background choices in text mode. Solutions: This is a limitation of the graphics card. IBM PCs have 16-bit graphics cards. Eight of the bits on the card are used for the letter, 4 bits for the foreground colors, 1 bit for the attribute (underline, italics, bold, etc.), with only 3 bits remaining. The 3 bits that can be used for the background color only allows for a choice of 8 color shades.
