PRM-45 projectors benefit from a Dynamic ECO setting, designed to save energy and increase lamp life.

If you have enabled this setting, you may notice that the projector automatically adjusts its brightness depending on the content it is displaying.

Should you wish to disable this setting, press MENU on the projector remote control and use the arrow keys to select the Installation II tab. Use the down arrow key to move down to Lamp Mode and press the left and right arrow keys to adjust the brightness to your preference.
