I have a toshiba P30 mobile desktop. It's heavy but it serves its purpose.
Occasionally, when I restart it, the screen will partially echo information
horizontal of the true pixels in the form of dos-cursor sized underscore
shapes. - certainly, the symptoms are digital in fashion (uniform noise
particle shapes) and not analog.
So A nice clean line like this
will turn out looking like the following in a noisy animated fashion...
| - _- -
| -- _ -
| - -
with the intended pixels repeated.
So that I may research this problem, I'd like to know what it might be
called? Even better, if you know what causes this....
It would seem that the video memory is receiving a pixel map, but some logic
in the video card is randomizing the output - that the problem is after the
video memory, but before the monitor output. Perhaps an AD converter is
picking up some noise somewhere that modifies the pixel output.. *shrug*.
Thanks in advance.
