Video Memory Modes

The monitor has 20 memory locations for display modes, 10 of which are factory preset to popular video modes.

User Modes

Modes 11-20 are empty and can accept new video data. If the monitor detects a new video mode that has not been present before or is not one of the preset modes, it stores the new mode automatically in one of the empty modes starting with mode 11.

If you use up the 10 blank modes and still have more new video modes, the monitor replaces the information in the user modes starting with mode 11.

Recalling Display Modes

When your monitor detects a mode it has seen before, it automatically recalls the image settings you may have made the last time you used that mode.

You may, however, manually force a recall of each of the 10 preset modes by pressing the Recall button. All preset modes are automatically recalled as the monitor senses the incoming signal.

The ability to recall the preset modes is dependent on the signal coming from your PC’s video card or system. If this signal does not match any of the factory modes, the monitor automatically sets itself to display the image.
