Choose “Tracking” item to synchronize the signal timing of the display to that of the graphic card. When you experience an unstable or flickering image, use this function to correct it.

“Frequency” is for changing the display data frequency to match the frequency of your computer’s graphic card. When you experience a vertical flickering bar, use this function to make an adjustment.

This function enables you to save your current settings for the computer source. To use this function, first choose “Custom Memory” from OSD menus, and go to the custom group you need (such as “Custom 3”), then select “Save” and press “Enter” to save your current settings; or choose “Open” and press “Enter” to load your preset settings. There are six groups of custom memories for your use.

If you want to come back to RGB standard source, go to the “RGB Standard” mode located before “Custom 1” in Custom Memory OSD menus.

*When opening your preset custom setting, you may experience a “Invalid” message appearing on the screen. This means the computer you connected or the current setting is the wrong one, not what you preset in the projection display.

*The “Reset” function of this projection display only works in RGB Standard mode.

Choose “Auto Image” from OSD menus to obtain an optimum quality for your projected image.

*“Auto Image” function will not support 1024 x 768 resolution.

*This feature could not perform well in case of input weak signal from VGA cable.
