Preventing Image Retention

Your plasma TV illuminates phosphor to display images, much like a conventional tube-type television. Viewing stationary images for extended periods of time results in uneven aging of the phosphor, causing grayed-out images to permanently appear on the screen.

Permanent image retention can be avoided by taking some basic precautions. Following the recommendations listed below ensures your plasma TV will have longer life and offer better performance:

•Whenever possible, avoid frequently displaying stationary images, such as Web sites, computer graphics, or video games for extended periods of time.

•Display video and images in the widescreen 16:9 ratio format. Use the Aspect button on the remote control to change from 4:3 screen size (such as standard television) to fill the screen in 16:9 ratio. This will prevent potential image retention of sidebars. Refer to “Selecting the screen aspect” on page 27.

•Avoid viewing the onscreen display (OSD) menus from DVD players, VCRs, and other components for extended periods of time.

•When watching a movie from a DVD player or VCR, do not leave the same image paused continuously over a long period of time.

•Turn down the contrast and brightness of the screen. High brightness and contrast can accelerate image retention of stationary images.

•Your plasma TV has a special feature that illuminates the entire screen and can remove very minor instances of screen image retention. See “Using the screen washing feature” on page 44 for more information.

Image retention and uneven screen aging are not covered by your HP Warranty; refer to the Warranty and Support Guide that came with your TV.

Wall Mounting or Stand Replacement

A specified technician from the distributor or authorized agent should install the TV, including stand replacement or wall mounting. Wall mounting brackets are sold separately and are not included with the TV.

Wall mounting the TV requires:

•Removal of the transport handles on the back of the TV.

•Removal of the stand from the TV panel.

•Assembly of the wall mounting bracket and installation of the bracket onto the TV panel.

•Placement and installation of the TV panel with wall bracket onto the wall.

Due to the size and weight of the TV, it is recommended that a minimum of two people move it.
