Checking the Digital-Signal Strength
Unlike analog channels, which can vary in reception quality from “snowy” to clear, digital (HDTV) channels
have either perfect reception quality or you will not receive them at all. So, unlike analog channels, you cannot
fine tune a digital channel. You can, however, adjust your antenna to improve the reception of available digital
channels.
1 Press the MENU button to display the menu.
Press the ▲ or ▼ button to select Channel, then press the ENTER button.
2 Press the ▲ or ▼ button to select Signal Strength, then press the ENTER
button. If the signal strength meter indicates that the signal is weak, physically
adjust your antenna to increase the signal strength.
Continue to adjust the antenna until you find the best position with the strongest
signal.
Press the EXIT button to exit.
Display Modes
If the signal from the system equals the standard signal mode, the screen is adjusted automatically. If the signal
from the system doesn’t equal the standard signal mode, adjust the mode by referring to your videocard user
guide; otherwise there may be no video. For the display modes listed below, the screen image has been optimized
during manufacturing.

Setting Up Your PC Software (Based on Windows XP)
The Windows display-settings for a typical computer are shown below. The actual screens on your PC will probably be
different, depending upon your particular version of Windows and your particular video card. However, even if your actual
screens look different, the same basic set-up information will apply in almost all cases. (If not, contact your computer or
Video Card manufacturer.)
1 First, click on Control Panel on the Windows start menu.
2 When the control panel window appears, click on Appearance and Themes and a
display dialog-box will appear.
3 When the control panel window appears, click on Display and a display dialog-box
will appear.
4 Navigate to the Settings tab on the display dialog-box.
The correct size setting (resolution)
Optimum : 1920 X 1080 pixels
If a vertical-frequency option exists on your display settings dialog box, the correct
value is 60 or 60 Hz. Otherwise, just click OK and exit the dialog box.
