How To

Setup

Why does the image looks stretched or fuzzy when I connect the monitor to my computer?

You must adjust the operating system’s display settings to match the monitor’s optimal (native) 1680 × 1050 setting. For information on adjusting settings in Windows Vista, see “Changing color depth and screen resolution” on page 8.

I do not see 1680 × 1050 available in the Windows display control panel.

•Make sure that your video card can display at 1680 × 1050 resolution.

•This may be caused by older video drivers on your computer. See the Gateway support Web site (support.gateway.com) for updated video drivers for your computer. You can also go directly to your video card’s support Web site for the most up-to-date video drivers. The Web sites for the major video card manufacturers are:

ATI®: http://ati.amd.com

Intel®: http://www.intel.com

Nvidia®: http://www.nvidia.com

When I run my games, I do not see support for widescreen displays. What can I do?

Newer games are adding support for widescreen displays as the widescreen format becomes more popular. Check the game’s Web site for updates. You can also consult the following Web site for specific settings and options to configure older games to support widescreen: http://www.widescreengamingforum.com.

Some adjustments may require you to make changes to the Windows System Registry. We recommend making a complete system backup before changing the System Registry.

Why do I see “noise” or “trash” on the screen?

When your display’s digital capabilities exceed a digital broadcast signal, the signal is increased (up-converted) to match the display capabilities. Up-converting can cause “noise” or “trash.” The signal on DVI-D is HDCP encoded. Stop and restart the source to allow renegotiation.

What is HDCP and how do I troubleshoot it?

High-bandwidth Digital Content Protection (HDCP) is a specification developed by the Intel® Corporation to protect digital entertainment content that uses a digital visual interface (DVI).

HDCP encrypts the transmission of digital content (signal) between the video source (computer, DVD player, or set-top box) and the digital display (monitor, digital television/DTV, or projector). HDCP is not designed to prevent copying or recording of digital content, but only to protect the integrity of the content as transmitted.

How does HDCP work?

Implementation of HDCP requires a license obtainable from the Digital Content Protection, LLC, which then issues a set of unique secret device keys to all authorized devices. During authentication, the receiving device only accepts content after it acknowledges the keys. To further prevent stealing of the data or line tapping, the transmitter and receiver generate a shared secret value that is constantly checked throughout the transmission. After authentication is established, the transmitter encrypts the data and sends it to the receiver for decryption.

What happens if I lose signal to the display while watching a movie on a HDCP-equipped component?

The component must be restarted to establish renegotiation.
