MY MONITOR SCREEN IS FUZZY. UNSURE THE CAUSE OF THIS, PLEASE HELP; COMPAQ MV730I MONITOR MAY BE JUST OLD ALREADY AND I NEED TO REPLACE IT.
Difficult to say as there are several possibilities. First would be to narrow them down. You may have already tried this, but wipe all dust off of the screen to see if that helps.(Do Not spray liquids on you monitor, if a cleaning agent is necessary, use a damp wipe to remove debris. If a single drop gets past the monitor's bezel in the wrong place, it will cook the monitor or worse, cook you.) If that didn't work, then, if possible, run the monitor on another computer. If that clears things up, I would suspect either a driver or hardware issue with the computer. If the screen is still fuzzy on another computer, then it is definitely the monitor. As CRT's age, many things happen. One is that the phosphor wears out from being shot at by the electron gun and start to go dim and then fuzzy as the intensity is increased by the user to make things brighter. Another thing that ages is the high voltage transformer. As the transformer weakens, it is no longer able to shoot a sharp beam of energy and begins to splatter a bit of energy on the surrounding pixels which would make the screen appear fuzzy. If the CRT has controls for adjusting intensity, contrast, saturation (those are sometimes hidden behind a small panel) tweak them one at a time remembering where the original setting was to see if that clears things any. ***DISCLAIMER*** (Note: Some monitors have the controls inside. If you are not experienced with adjusting high voltage devices DO NOT DO IT!!! A monitor is not worth your life, and if you disrespect high voltage even by accident, the potential is there to kill you!) Above all things, BE SAFE, and then choose what is best for you to do. Best of luck.
