CHAPTER 1: Using Your Gateway Flat-Panel Monitor
28
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.
How do I know if a component is HDCP compliant?
If the video source device does not have a DVI or HDMI connection, it is not HDCP compliant.
