Using the VGA Utilities

Your computer has a Video Graphics Array (VGA) adapter built into the main system board which is 100% compatible with IBM VGA. This adapter allows you to use the computer with Epson VGA monitors, other brands of VGA monitors, and VGA compatible, multi-frequency monitors that use analog input (in non-interlaced mode only). The internal VGA is supported by the Chips and Technologies® SuperVGA 82C452 controller.

In addition to its VGA support, the controller offers a large set of extended functions and higher resolutions, which you can use if you have a multi-frequency monitor capable of displaying these resolutions. The built-in adapter’s capabilities include:

High-speed video memory interface

16-bit datapath to video memory and hardware registers

Resolutions of 800 x 600 or 1024 x 768 in graphics modes with 16 colors

Resolutions up to 640 x 480 in graphics modes with 256 colors

132-column text mode in 16 colors

Graphics cursor movements performed by the video adapter controller.

The Epson standard VGA monitor uses VGA modes in resolutions up to 640 x 480 and does not need any software drivers to operate properly. You need to install software drivers only if you want to use extended VGA modes (in resolutions up to 800 x 600) or super-extended VGA modes (in resolutions up to 1024 x 768) on a multi-frequency monitor.
