"Well after the external video jack (which is analog video), it
gets converted to digital and fed to the LCD display."

This is a driver issue, but that explanation of how things work is
wrong (although irrelevant to the issue). The digital video is
produced natively. The analog video is then produced from that. Not
the other way around.

But Pete (the OP), also stated on the 23rd that he booted up with :
"TuffTest Pro (http://www.tufftest.com/ttp01.htm) that is self-booting,
operating system independent and never goes anywhere near Windows". So
how can it be a Windows driver issue if the problem still exists without
Windows?

And it is converted to digital, to analog, and back partially into
digital (a mix of the two). Same thing happens when you plug into an
external LCD monitor as well. As the pixels live in a digital matrix,
while the contrast is controlled by analog means.
