monitor display is getting blurry...what could be the problem?
is the video card that is sending faulty signals? or is it the monitor. The monitor is a Mag MXP17F about 6 years old. Any thoughts? Is there someway I can definitely confirm that the monitor is faulty or the videocard. Can I focus the monitor? -walter ps. No it is not by eyes. The monitors I use at work are much clearer and no it is not the Vert refresh rate, it is 100Hz.

Can I focus the monitor? 6 years old ... that's pretty old. I read once that TV manufacturers only expect an average lifetime of 5-7 years. The monitor may be getting dusty, or the electron guns may be misaligned. I know someone who had a large TV that had a mirror at the bottom so it was much shallower than a regular TV. It started to get quite dim after some time. When he opened it up there was a lot of dust on the mirror. Cleaning the dust off solved the problem. (might not be relevant, but ...) If you can try replacing the monitor _or_ video card. By changing only 1 of them you can determine which is causing the problem. Changing the monitor is probably the easiest to do, if you have a spare monitor you can try. -D

That is to say, components subjected to heat and aging. For example, the cathode of the CRT could be losing emission. One thing is did you change monitor cables for any reason recently? Perhaps a longer one? The sharpness of pixels is related to the signal loss in the video cable, which goes up with length. This increases (slows) the risetime of the video pulses and causes pixel smearing. And these are only two of the possible causes! The best way would be to borrow one of the monitors from work for a night and check it against your video card. Conversely you could bring your monitor into work. Cheers, -rick

FWIW - If your monitor has an alternate set of BNC connections (RGB) it may pay to switch to using a BNC cable. I found with my Iiyama monitor that I got a much better signal with BNC cables. See if jiggling the cable end (both ends) changes the blurryness. That could be a clue that it's either the cable or the connector. You could try a contact cleaner spray (Radio Shack) on the connectors. That also made a difference for me. Cheers, Steve
