Image is not centered?

To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.

Here is my suggested way to procede:


1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2.
2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen.
3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.

4. Adjust HIT with volume up/down control for the image height to 22.5 inches.

6. Adjust WID for image width of 30 inches, (22.5*4/3)
7. Adjust HPOS to center the image.
8. Adjust PARA and TRAP to minimize geometric distortion.
9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines.
10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid.
11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines.
12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches.
13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen.
14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction.
15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details.
16. Enjoy 1080i.

Other Comments:
I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.

Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.

I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.

Another mistake I made was not realizing that the cursor color determines which grid gets moved.

Solution : Perform an Automatic Gradation Adjustment (Color Calibration) Automatic Gradation Adjustment compensates for tones when the color tones shift in color copies / prints. Compensating for color tones maintains the quality of color copies / prints made by the machine at a fixed level.

NOTE: Output of the Automatic Gradation Adjustment chart is added to the metered copy count.

NOTE: When Gradation Adjustment is selected, the following changes will be made to default copy settings set in System Settings mode:

• Copy Density = Normal or Auto
• Color Shift =Normal
• Saturation = Normal
• Color Balance = 0
• Sharpness = 0

1. Press the [Access] button (key symbol) on the Control Panel. The Access button is located above the number "3" on the numeric keypad.
   
   
2. Using the numeric keypad, enter your administrator password and select [Confirm] on the Touch Screen. The System Administration Menu screen will be displayed.
   
   NOTE: If you do not know the password, contact your administrator. The initial password at machine install is 11111. If the administrator encounters a problem with changing the password, or forgets the password, a service call must be placed.
   
   
3. Select [System Settings]. The System Settings screen will be displayed.
4. Select [System Settings] again.
5. Select [Common Settings].
6. Select [Image Quality]. The Image Quality Adjustment screen displays.
7. Select [Automatic Gradation Adjustment].
8. Load 8.5 x 11 inch (216 mm x 279 mm) or A4 (210 mm x 297 mm / 8.3 x 11.7 inch) paper in Tray 5 (Bypass Tray). Adjust the paper tray edge guide so that the guide gently touches the edge of the paper stack.
9. Select the desired gradation adjustment screen.
10. Press [Start]. The Adjustment Chart is output.
    
    NOTE: When printing the color chart for Auto Gradation and you get the message,'Auto Graduation Procedure has completed with an error' make sure that 8.5 x 11 inch (216 mm x 279 mm) paper is loaded into Tray 5 Long Edge Feed (LEF).
    
    
11. Place the Adjustment Chart face-down on the Document Glass with both the Magenta color patches against the left side of the glass.
12. Place 5 sheets of white paper on top of the Adjustment Chart and close the Document Glass Cover.
13. Press [Start].
14. To continue Automatic Gradation Adjustment with other screens, repeat steps 6 to 10. When you are finished, select [Close] until the System Settings screen is displayed.
15. Select [Exit] to exit the System Settings mode.

Hope it helps!

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.
