Solutions: Super VGA Info Sheet Video Memory Requirements: CGA 640x200 2-color requires 16K EGA 640x350 16-color requires 109K Super VGA 800x600 16-color requires 234K Higher memory does not enhance the performance of the video card, but does allow for more colors to be displayed. A 256K VGA card is capable of 640x400 256-color or 800x600 16-color or 1024x768 4-color A 512K VGA card is capable of 640x480 256-color or 800x600 256-color or 1024x768 16-color The 800x600 Super VGA mode requires a monitor that is capable of a 35 kHz horizontal scan rate. A 1024x768 VGA mode requires a monitor capable of 49 kHz horizontal scan rate. High-end MultiSync monitors provide this capability. Some MultiSync monitors do not. Many video cards are capable of higher resolution or more colors than monitor hardware or software supports. The high resolution modes can only be used with special software drivers. Many video card manufacturers provide video drivers for several software products. 16-bit VGA cards for 286 or 386 machines perform approximately twice as fast as their 8-bit counterparts, according to PC Magazine benchmark tests. |
