Matrox Electronic Systems LE G450, LX G450 Solution Disable the display, Windows* 98/Me/2000/XP

Cause If you’re using multi-display mode, the program window or dialog box may be in a display or on a monitor that’s unusable.

Solution Make sure all the displays and monitors you want to use are usable. For more information, see other troubleshooting items in this guide.

Cause The software may be using a display you didn’t intend to use or the software may be configured to use more displays than the actual number of monitors you have. (For example, you may be in DualHead Multi-Display mode but you only have one monitor.)

Cause The program window or dialog box may be somewhere off-screen.

Solution If the program window you want to see is named on the Windows taskbar, right-click on it and select Maximize. (If you click Restore the program window goes back to its previous position. To fix this problem, see the other solutions.)
