Other adjustments

If you are not satisfied with the picture quality made by the preset modes, you can manually adjust some of the settings through the On-Screen Display (OSD) menus.

Adjusting brightness

Press MENU on the projector or remote control. Go to Display > Brightness and adjust the values by pressing Left/ Right on the projector or remote control.

The higher the value, the brighter the image. And lower the setting, darker the image. Adjust this control so the black areas of the image appear just as black and that detail in the dark areas is visible.

Selecting a color temperature

The higher the value, the more bluish white the image becomes. The lower the value, the more reddish white the image becomes.

About color temperatures:

There are many different shades that are considered to be “white” for various purposes. One of the common methods of representing white color is known as the “color temperature”. A white color with a low color temperature appears to be reddish white. A white color with a high color temperature appears to have more blue in it.
