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®:

When I connect the monitor’s USB hub to my computer, I see an error message saying that 
my USB hub may not be running at full speed. 
This can happen if you connected the monitor’s high-speed USB 2.0 hub to a low-speed USB 1.1 
hub or a USB 1.1 port on your computer. To use the monitor’s high-speed USB 2.0 capabilities, 
you must connect the monitor to a USB 2.0 port on your computer.
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:

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. 
Technical
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.
For example, while watching a movie on a HDCP-enabled DVD player, you change the receiving 
device (DTV, monitor, or projector) input to watch broadcast TV, then change the input back to 
watch the DVD movie. However, you are unable to watch the movie. This is because when the 
input was changed, the receiver lost the HDCP signal. Restart the HDCP-enabled DVD player to 
allow renegotiation. 
What is the cause if a movie starts and then slowly fades to static? 
The receiving device is not HDCP compatible or it is not negotiating correctly. Restart the video 
source and re-plug all video cables from the source to the TV.
