How i adjust horizontal size and vertical size


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.

Toshiba m50-mx2 powers up okay but no display


when you have the memory in and you boot up does it look like the hard drive LED is flashing? If so then its booting up into windows and that would mean a bad Display. If nothing happens then try a different stick of good RAM and see if it boots up then, if still nothing then it sounds like a bad motherboard.

Toshiba 43H70 convergence


You will have to contact toshiba at 1-800-457-7777 and get a service manual to adjust the on board menu and adjustment.. I do not or ever ever recomend that an unexperienced person mess with the sets alighnments unless they have the service manual and understand all of the teminology as I've seen several sets that cost the customer 4 times what it would have if they didnt mess with the service menu and knock all the alighnments as this is not the time to adjust someting just to see what happens.
