Technical information

To avoid future problems the display adapter must be set for modes supported by the monitor. The manual

for the monitor should provide a list of compatible resolutions and refresh rates (note that all refresh rates

will not work at all resolutions). The safest resolution is 640x480 with a refresh rate of 60Hz (most multi-

syncing monitors support this mode). When using any other settings, make sure that the user always tests

any resolution or refresh rate before setting it.

Another common problem is installing software not designed for Windows NT 4.0 (ie. Windows 95/98

software). Many of these programs can corrupt the video drivers in Windows NT, if not the operating system

itself. Never install software which does not specifically support Windows NT 4.0.

Supported resolutions and frequencies

Any monitor will support only specific resolutions at specific frequencies. The owners manual for the mon-

itor should list all of these video modes. Below are listings for common monitors shipped from PCComplete.

This information is from the manufacturer’s technical support departments and may have errors. It is always

important to test the settings before accepting them.
