If Video Plug and Play is in Setup, and a DDC monitor is detected,
enabled
Setup will automatically configure the best refresh rate. For non DDC
monitors, or when video Plug and Play is , refresh rates can be
disabled
changed in Setup.
The number of colors supported is limited by the graphics card and the
video RAM. The resolution/refresh-rate combination is limited by a
combination of the display, the graphics card, and the video RAM.

Connectors

The layout of the pins for the DB15 VGA socket are depicted on page 62.
The Video Electronics Standards Association (VESA) defines a standard
video connector, variously known as the VESA feature connector,
auxiliary connector, or pass-through connector. This connector (whose
pin names are listed in a table on page 58) is integrated on the system board,
and is connected directly to the pixel data bus and the synchronization
signals.
The graphics controller supports an output-only VESA feature connector in
VGA mode. It is disabled by default and must be enabled in the Setup
program. Use of the VESA feature connector will disable the 1 MB video
memory upgrade, if one is installed. Only the standard 1 MB of video
memory will be used.

Troubleshooting

To get the hardware configuration information, click on the "Control Panel/
Display/Settings/Advanced Properties" menu in Windows 95. This gives
information of the form: Manufacturer=S3, Chip Type=775 Rev E, DAC
Type=Internal, Memory=1 MB, Features=DirectDraw, Software Version=4.0.
The "Software Version" is the version number of the driver builder. To obtain
the driver version, you need to click on the "System/Device Manager/Display
Adapter/S3 Trio 64V2 Hewlett-Packard VL5" menu. To obtain the version
number of Microsoft DirectDraw, find the file, and click on
Ddraw.dll
Properties with the right mouse button.
