Wide screen monitor distortion Depending upon the screen resolution that has been set in Display, the image will be distorted on these large wide screen monitors. To correct this distortion. 1. Create a large circle image using a draw program such as Paint (hold down the Shift key as you create the circle as it will draw a perfect circle). 2. Open Control Panel - Display - Settings tab and adjust the Screen resolution slider, increase or decrease the screen resolution then bring the circle image to the front and check the image, if the circle is still distorted then change the screen resolution and check the circle again until you are satisfied with the image of the circle. 3. When you are satisfied then click apply.
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.
This is a common problem with wide screen format.
The way I overcome this distortion is to open a drawing program and draw a circle, some programs require you to hold down the shift key to produce a perfect circle.
I then go to the Display Settings and adjust the screen resolution to get the best display that fills the screen and that gives me the perfect circle.
If this does not work you may need to download the latest video driver for your graphics card and then adjust the screen resolution..
The distortion mostly is caused by a wrong screen resolution. Choose another (smaller or larger) resolution and once you've found the correct resolution for your display card tne distortion will be gone.
things can cause static.
If you have your speakers turned up to high it will give you feedback causing
distortion and static. I recommend using a headset when videoing.
reason is, if you are using a laptop and have added an external microphone
between the two it will cause distortion and static.
knowing the configuration of your computer makes it harder to analyze the
hope this is of some help. Bud
I am assuming that the reason you are using Excel is because of the gridlines. An "engineering drawing" done in Excel would break when rotated especially the angular lines. The reason is Excel does not have the necessary engine to display (render) such drawings. By Excel alone, there is no way out of this problem.
However, there is a workaround. After making the drawing, before rotating it, do a Print Preview. Open an image manipulation program, even a simple one such as PaintShop Pro. Capture the image on the Print Preview. Open another Excel sheet, copy and paste the image from the image manipulation program to the Excel sheet.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
Have you connected the laptop to another monitor and use the same refresh rates that cause the distortion? If the distortion appears on a different monitor, then I would have your laptop examined by a pc engineer, but, if the distortion only appears on the 997DF monitor, I suggest having the monitor checked at a repair shop, also, have you tried connecting the 997DF to a desktop PC, and use the same refresh rates?
