Strange Monitor Issue
I have a large Mitsubishi CRT monitor which appears to have a fractal
like defect in the screens outer glaze. This appears as a clear series
of 'fractal' like marks specifically to the left hand side of the
screen. From what I can see there would appear to be a very faint dark
coating to the overall screen. Within that coating there are lines and
scratch dots over a good area of the surface making the image look as
though there are defects within the picture. It is most noticeable with
a white image. There are also defects in the surface appearing as bubble
like areas to the perimeter.
I have Googled the problem but cannot find any reference to it. It is
not on the monitor tube itself as that appears to be a quarter of an
inch behind this outer flat glass screen. The image itself is crystal
clear, bright and very sharp and deep in black which is a good sign. The
image is not dim. There has been no abrasion to the surface and only use
of a proper monitor screen cleaner. The monitor has been in store a good
while though. I have two more of these large monitors and they do not
demonstrate any of these problems. In simple terms if you say steamed up
a piece of glass and then scratched your fingers clearing the
condensation in a random way that is how I would describe the affect.
More like fractals that grow out is more like it.
I have swapped the monitor out as it really was annoying me. There are
no surface abrasions and there is no reaction to them from touching the
screen. I also note a faint pinkish small vertical line at time as you
cast your eyes over the imperfection.
I do have a similar problem with an actual flat screen monitor where to
the edges on one side there has been a general degrading of the surface
appearing as faint bubbles which are growing steadily. Difficult to
explain as it is a transparent issue that is in the surface coating I
fear to the monitor screen to provide some kind of anti glare surfacing.
If you have ever heard of the issue it would be great to find out. I
cannot see there being any repair to the problem. However if there is a
cause which could be avoided I would like to know as CRTs are becoming
rare as they age and become dimmer. Difficult to replace and I do like them.
All help appreciated.
