Oversized screen
If the picture edges are not visible, the image is overscanned. This condition is common when connecting a
computer to a TV. Overscan is when the video image size is greater than the TV/Display screen. In an overscan
condition, the edges of the video image that are not visible on the TV/Display screen are cropped.
Panning allows you to see the edges of the video image and can be a corrective action for overscan. See
“Aspect ratio” on page 33 for additional information. See the following for overscan problems and solutions:
Left: Video image is cropped.
Right: Video image is full screen, not cropped.
Problem: Desktop video image edges are not visible. Your TV/Display might show only the center of the video
image, not the edges. This problem may occur if you change video formats or TV/Displays.
Solution: If you want to see a full image, or cannot move the cursor off the screen to see hidden areas of the
video image, optimize the HP Digital Entertainment Center video image so it fits your TV screen:
Do one of the following:
• If your TV connects to the HP Digital Entertainment Center using a component video connection, use the
TV/Display Setup Wizard. See “TV/Display Setup Wizard” on page 5. Follow the onscreen instructions.
Or
• Perform the HDTV Overscan Compensation procedure and Set underscan. See “HDTV Overscan
Compensation” on page 12.
Or
• If your TV connects to the HP Digital Entertainment Center using a composite or S-video connection, see
“Adjust Composite Video and S-video Screen Size” on page 13.
To increase or decrease the size of your HDTV desktop, do the following:
1 Press Media Center on the remote control or keyboard.
2 Click More Programs, HP Settings, and then Video Settings.
3 Click Resize Desktop and Resize Desktop.
4 Adjust the screen size to fit your display. If your display shows a larger image than the screen and the edges
are missing, click the “in” arrow button to make the screen smaller. Click Save Settings to apply the settings.
5 Click Back to return to Media Center.
NOTE: To access hidden buttons if the edge areas of your desktop video image are not visible, move the mouse
pointer in the direction of the missing area, the whole desktop moves, or pans, to follow your mouse pointer
movement.

HP Digital Entertainment Center TV/Display Setup Guide
Display resolution/format
Display resolution refers to the number of pixels on your TV/Display screen. The following table shows pixels that
correspond to standard Video Out formats:
Format
4:3 aspect ratio
16:9 aspect ratio
480i, 480p
640 by 480 pixels
853 by 480 pixels
720p
960 by 720 pixels
1280 by 720 pixels
1080i
1440 by 1080 pixels
1920 by 1080 pixels
For example, 640 by 480 pixels refers to the size of the screen. 640 is the width of the screen, and 480 is the
height of the screen, in pixels.
The HP Digital Entertainment Center does not support 1080p, but most 1080p TV/Displays support 1080i.
Many TV/Displays specify a native resolution which is recommended by the display manufacturer. You may have
to adjust the HP Digital Entertainment Center to use the native resolution. Your display resolution setup may vary
by TV/Display type.
To optimize the HP Digital Entertainment Center video image so it fits your TV screen with component video
connections:
• Use the TV/Display Setup Wizard. See “TV/Display Setup Wizard” on page 5.
Or
• “HDTV Overscan Compensation” on page 12.
Or
• To adjust your display, see “Desktop Video Adjustments” on page 14.
Scanning system
Interlaced or progressive refers to the scanning system. Interlaced scan formats are 30 Hz. Progressive scan
formats are 60 Hz. 30 Hz or 60 Hz is the screen refresh rate. The screen refresh rate is the rate at which a
monitor or television can redraw the screen from top to bottom.
NOTE: NTSC Component Video Out refreshes the screen approximately 30 times per second (30 Hz) when
using interlaced formats, and 60 times per second (60 Hz) when using progressive scan formats.
In an interlaced format, the TV/Display screen shows every odd line at one scan of the screen and then follows
that up with the even lines in a second scan. Since there are 30 frames shown per second, the screen shows one
half of the frame every 60th of a second. For smaller TV/Display screens, this is less noticeable. As TV/Display
screens get larger, the problem with interlacing is the potential for a flickering display. Progressive scan formats
eliminate flicker.
Aspect ratio
The aspect ratio refers to the ratio of the width to the height of the display screen. 720p and 1080i are typically
16 x 9 widescreen aspect ratios. 480i and 480p are typically 4 x 3 aspect ratios, the standard TV screen.

Display Image Size
Your screen may show a larger image (Overscan), which may Pan when you move the cursor past the edge of
the screen. The large screen size may Crop the video image so the edges appear to be missing. This condition is
common when connecting a computer to a TV because most TVs introduce an overscan of five to fifteen percent.
To optimize the HP Digital Entertainment Center video image so it fits your TV screen, use the TV/Display Setup
Wizard. See “TV/Display Setup Wizard” on page 5. Follow the onscreen instructions.
Overscan
In this illustration, “2” shows the (light blue) edges of the
Media Center video image that are not visible on the
TV/Display screen. The text above the screen is cropped.
1 TV viewing area
2 Full video image
Cropping
Cropping is the condition when the edges of the video image
are not visible on the TV/Display screen. The screen cursor
disappears when moved past the edge of the screen, if
panning is not enabled.
The drawback of the 640 x 480 (Low) resolution setting is that
desktop pop-up windows may be cropped in 480i and 480p
resolutions. Pop-up windows may not be able to display the
bottom portion of the window, depending on the height of the
window, where the OK, Cancel, and Apply buttons are
located.
Pop-up window showing lower buttons
Panning
Panning allows you to see hidden areas of the video image by moving the cursor to the edges of the screen.
Move the cursor to the edges of the screen to reveal the hidden areas. When you move the cursor, the screen
image moves. Media Center may not allow panning to access the hidden screen areas. The Windows desktop
allows panning. The screen cursor disappears when moved past the edge of the screen, if panning is not
enabled.

A stationary image on your plasma TV/Display may retain the image on the screen if left on for prolonged
periods. To avoid image retention, follow these guidelines:
• Always use a screen saver from your HP Digital Entertainment Center display settings.
• Avoid keeping a stationary (unmoving) image on the screen for extended periods. Stationary images include
but are not limited to:
• The Media Center user interface or PC desktop
• Still image/photo or video paused for prolonged periods
• Use low-contrast colors for desktop background images.
• Reduce brightness to around 50 percent.
• After displaying any still image, play back a video in the Wide or Full screen setting for over three times
longer than the previous still image.
