MS-DOS-Based Programs Can Be Run Only on Primary Monitor

If you have multiple monitors connected to your computer and you run an MS- DOS-based program, it may be run only on the primary monitor.

This behavior can occur if you are running the MS-DOS-based program in full-screen mode.

To work around this behavior, run the MS-DOS-based program in a window. To do so, press ALT+ENTER.

This behavior is by design.

Windows 98 runs full-screen MS-DOS-based programs only on the primary monitor.
