Changing the Display Size (Horizontal Amplitude and Ver- tical Amplitude)

The projector already stores the standard personal computer and work station resolutions in standard memory. When an RGB signal is input, the closest resolution is selected from among those stored and the signal is displayed. (When the information is stored in the user memory, it is searched from the user memory.) It is for this reason that when the scanning frequency differs from the value of the standard memory, the display area or aspect ratio will also differ. The horizontal magnification and vertical magnification are used to adjust this.

• Adjusting the Horizontal Amplitude

This function adjusts the horizontal display size to suit the screen. Select [Alignment] → [H Amplitude] from the main menu.

When the item to be adjusted is selected, the adjustment value of the selected item is displayed at the bottom edge of the display.

Adjust the horizontal amplitude with the cursor ◀ (–)/▶(+) button.

The adjustment range will differ depending on the input signal.

Holding down the button will result in a continuous change. Fine adjustments can be made by single presses of the button.
