When you connect your LV-7575 to different sources with different content, the projector gives you optimum image quality through an array of image modes:
Standard (PC, video) for normal viewing.
High Contrast (PC) for projecting sharper graphs and photographs.
Cinema (video) for watching movies in a darkened room.
Custom (PC/video) lets you adjust several factors, including gamma. Gamma adjustment affects the overall brightness of an image, making it useful for images that are too dark or too bright. Up to 10 custom profiles can be stored.
