Smudgy image on monitor

By jardinier ·
About three years ago I gave an old computer to a woman who had been kind enough to let me store some of my "suff" in her shed.

She spent hours playing Windows solitaire and then moved on to Tetris. After a period of many months enjoying Tetris, she telephoned me to say there were smudgy images all over the screen.

Before I got around to calling on her, someone else had fixed the problem. I ascertained that this person had eliminated the problem by altering the display from 256 colours to 16 colours.

This is something that would never have occurred to me. I would have just done a full reinstal. Can someone please explain why changing the display eliminated the symptom?

Jules,

The most likely explanation is that the Monitor is going bad and with the lower color display it's not as noticeable with the problem. Or the Video Drivers could have become corrupted and the machine is now running on the Windows Default Video Settings without the correct Video Drivers installed.

If the image is going fuzzy or looks like a Ghost image that you used to see on some TV Sets the Focus control of the monitor had drifted out and needs readjusting which may not be an easy thing to do particularly with some of the older monitors as there is no external Focus Control Knob to adjust on and you have to open the monitor case and adjust a Potentiometer with a Plastic Screw Driver or run the risk of getting a massive electric shock as the thing is mostly metal and at the very least the side that you adjust on carries part of the charge. Of course when you get a hit your hand jerks off the adjuster and most times into something else with a much higher charge. :^0

Sometimes depending on the make of the monitor you need to replace the monitor as just dropping the color setting back is at best a Stop Gap Measure.

It sounds like the monitor may be loosing its
focus. This can be adjusted, but I don't
recommend that any unskilled person attempt
to adjust it. The voltages are high and could
cause a real jolt, even deadly to some. At the
price of displays these days, replacement would
be the quickest and easiest solution.

Probably not the correct answer but thanks for trying.

I would go with this answer: "the Video Drivers could have become corrupted and the machine is now running on the Windows Default Video Settings without the correct Video Drivers installed."

The monitor has totally sharp, clear, rich colours on the setting of 16 colours.

Hence what I would have done -- if this other person hadn't changed the display as a temporary fix -- would have been to do a complete reinstal, and so I guess my own diagnosis is correct.

I have oodles of spare monitors so no problem with replacing the monitor.

Perhaps I have confused the issue by using the word "smudgy" which probably could be interpreted at "blurry."

A more precise description would be some drunken spiders wandering around the screen, gathering friends as they went.

As I have noted, I will go along with Hal's suggestion that the video drivers in the OS have become corrupted, but it had also occurred to me that the video card or chip might be the culprit.

I would appreciate comments as to whether this could conceivably be the cause of the problem.
