hi there, Below the monitor, on the center are option button, you can explore that in adjusting your screen display. You can widen the display, or tweak it depending on the angle that you need to. Just press the center button and choose from the menu.

Screen stretched out horizontally and distorting picture. None of the settings buttons appear to solve this. I can shift the image vertically or horizontally; but not squeeze it horizontally.


There are adjustments in the size of the items on a screen under the screen properties, settings. If you right click on the desktop screen and then properties you can get there. There is at least one size which causes a distortion of images being displayed. This may be your problem.

Distorted picture on my 32" Proscan TV...(about 15 years old)


The RCA GE sets have a problem with bad solder connections in the tuner unit which also causes numerous symptoms including poor regulation, no vertical deflection, low audio or dead set.

Pulling in from the sides is either poor regulation or a bad eeprom/solder join issue

Image problem


IF I understand the problem from the limited info in your question, the problem is a distorted picture on whatever surface [probably a wall, or screen] onto which the image is projected.

With all lenses, the axis [centerline of the lens projected] MUST be absolutely PERPENDICULAR [in both the vertical and horizontal planes] to the perfectly plane [flat] surface onto which the image is projected.

IF for example, the projector is mounted in a rear corner of the room, and the camera is aimed downward and to one side to project the image on the center of the opposite wall, or a screen located there, the image will be distorted. It will be larger on one edge [fartherist from the lens] and smaller on the opposite [nearest] edge.

If it is non-perpendicular in only one axis, then two opposite edges will be different lengths, and if out of perpendicular in two axis then no edges will be the same length.

The solution to this problem is that the center axis of the lens must be perpendicular to the surface projected on, in both vertical and horizontal axis.

The positioning of my desktop's imageis still distorted despite running the easy tune display wizard and my using the auto tune keys on the side of the monitor.


Use the manual methods on your monitor (horizontal and vertical size and position), not the auto tune and see if you can get it to improve.

Try using a different desktop picture as well.

Right click on the desktop where there are no icons, and change the picture. Also, play with Stretch/Center/Tile - stretch will distort a file if it doesn't exactly match your screen settings.

We have had similar issue w/ multiple LP70+ projectors. The units get to be 1-2 years old and suddenly the right vertical edge of the display is distorted. There is usually a shadowed vertical bar that clouds about 3-5% of the horizontal space from the right edge.
What's the cause?

Screen image display distortion


Hello.
What you are reporting is a problem in the pincushion circuit in the horizontal section of your CRT monitor. Usually this is from an electrolytic capacitor that is no longer willing to play nice with all the other components.
It is repairable, but get an estimate first. If the repair bill appears to be around $100, you would be better off to put a few more dollars with that and buy an LCD TFT monitor.
If you are quoted $25 or $30, it is probably worth having repaired. Just keep in mind that these older CRT monitors have age on their components, and once repaired, it will still be an old monitor.
Only you can decide which choice is right for you. At least now you have a few facts to help make the decision.
I hope this helps.

Distorted picture


The RCA P52960 uses the PTK195 series chassis. There are 2 main boards at the bottom of the set and above the board on the right (when viewed from behind) is the convergence power supply board. This board usually has a big black IC on it, labeled STK730-010 and bolted to a metal heat sink. Chances are, that IC has burned out and stopped working. Replacing that IC should restore your convergence. If you do not have experience replacing IC's in projection sets, allow a qualified tech to handle it for you.
