SONY VPL-CH375 PROJECTOR:  Hardware Tour - Menus


The VPL-CH375 has a rather straight forward menu structure.  When you press the Menu button on either the projector's control panel or the remote control, the Picture Menu is displayed as shown in the photo below.

A series of icons appear down the left side that are used to select the desired menu with the top icon representing the Picture Menu.  The first item on the Picture Menu is to select the Picture Mode.  Unlike most business/classroom projectors, this projector only offers three picture modes:  Dynamic, Standard and Presentation. When the second Picture Menu item is selected it Resets the picture adjustments to the factory default values. The Picture menu items for Contrast, Brightness, Color, and Hue perform the typical functions for these common picture adjustments. The color temperature item on the Picture Menu allows the user to select from Low, Middle and High, where a low setting will produce a "warmer" image and a middle and high settings will produce increasingly "cooler" images. The Sharpness adjustment provides the typical edge enhancement to the image. The final item on the Picture Menu is for Expert Setting.   When selected, this displays a menu for selecting different Gamma presets, as shown in the photo below.
