3.3.1 Selecting the Picture
Selecting the source (picture) manually is usually quicker than using the SETUP button.
Selecting the picture is really selecting the input con-
nector. There are three of these connectors:
• Analog/Digital Computer
•Composite Video
•S-Video
Computer sources
Use Computer connector for either analog inputs,
the type we’ve used for years with computers, or digi-
tal inputs, the newer DVI standard. Either of these
accepts pictures of the following common standards
as well as many, many others:
Component video sources
Analog sources that are YPbPr instead of RGB are
selected in the Picture menu with “Analog,” but the
Colorspace must be changed to YPbPr Component
Video.
DVD sources
DVD players have composite video and S-Video
outputs, and they sometimes have component video
outputs from three RCA connectors. The component
output is in YPbPr form. You must select YPbPr for
the Colorspace item in the Picture menu. See “YPbPr
sources” on page 18.
Composite Video and S-Video
These two inputs accept NTSC, NTSC at 4.43/60,
PAL, PAL at SECAM video pictures.
To s e l e c t t h e s o u r c e
1. After the display is on, press
MENU on the remote.
This opens the Main Menu.
2. With Picture highlighted, press
ENTER.
3. Use the left-right arrow keys on the remote to
select the type of source, and press
ENTER.
a) Analog RGB
b) Digital RGB
c) Comp Video (composite video)
d) S-Video (Y/C video)
4. Close the menu by pressing
ENTER, or let it time
out.
The resolution or type of source picture currently
coming in is displayed on the line just below Source.
This is grayed out because you can’t adjust it.
Analog sources
With the Analog RGB sources you can adjust Fre-
quency, Phase, Brightness and Contrast and choose
the amount of Sharpness you want the displayed pic-
ture to have.
The fastest, easiest way to adjust Frequency and
Phase is to press the
SETUP button. If Do Frequency
and Do Phase are checked, both these adjustments
are completed in one second.
Manually adjusting Frequency and Phase can be
accomplished if you have a checkerboard pattern on
your computer. A checkerboard is a pattern in which
alternate pixels are black and white. It is the most dif-
ficult picture for the electronics to handle.
Making a checkerboard in Windows
1. Start the Paint program.
2. In the menu bar, select Image > Attributes.
3. Choose the Width and Height of the resolution in
pixels. In Colors, choose Black and White.
4. Click OK and answer Yes in the next box.
5. Near the bottom, find the row of gray shades that
starts with white. Counting the white chip is “1”,
click chip number “9”.
6. Click the spilling paint jar from the tools at the
left.
7. Click in the picture area. This picture now has
black and white pixels alternating.
Manual adjusting Frequency and Phase
1. Display a checkerboard pattern from the com-
puter that will be used for program material.
2. Press
MENU, select Picture, and press ENTER.
3. Select Frequency. Use the right-left buttons to
change the frequency up and down to eliminate
vertical banding in the picture.
