Video Memory Modes
This multi-synchronous auto-scanning monitor can automatically detect and display several video modes falling within the monitor's scanning range of 30-85KHz Horizontal and 50-120Hz Vertical. In the PC area, this relates to a maximum flicker-free usable resolution of 1280x1024 at a non-interlaced refresh rate of 75Hz Vertical. For convenience, the monitor has a 40 mode memory, of which 8 modes come from the factory preset to popular video modes as described below.

Modes 17-40 are empty and can accept new video data.

If the monitor detects one of the above signals from your computer's video card, it will recall that mode and any stored image adjustments you may have made before. If the monitor detects a new video mode that had not been present before or is not one of the above listed factory presets, it will store a new mode automatically in one of the blank (empty) memory modes (in this example, mode 17). When you now adjust the OSD controls to your preference, these image settings will also be stored in mode 17. Whenever your video card or PC switches to the mode that the monitor recognizes as mode 17, your personal image settings will also be recalled.
