| laptop screen noise terminology? 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. -JB |
