The video cards for MS-DOS computers have different timing than the Apple monitors. With the exception of Multiple Scan displays, Apple monitors are locked into a specific scan rate, which matches the Apple video cards, and cannot be changed.
However, many modern PC graphics cards can be made to run with Apple compatible timing, usually through software drivers. You would need to check with the card vendor to ensure compatibility with Apple monitors. Also, check the monitor user's manual for additional information like cable pinouts.
Many third-party monitors adapt to a variety of scan rates, just like Apple's Multiple Scan displays. We do not have a reference list of third-party monitors that are Macintosh and MS-DOS compatible. Contact the monitor manufacturer to determine a monitor's ability to work in both environments. Generally, monitors used with MS-DOS computers are known as EGA-, VGA-, CGA- (or similar "xGA-") compatible.
