I have a trinitron monitor that has suddenly become way too bright. Even when I set brightness at 0 it is still as bright as it used to be set at max brightness. (The brightness control does work -- it's just that minimum brightness is now still very high for some reason.) I can further reduce brightness by using the my video-card control-panel, which makes the monitor usable with my desktop machine, but if I switch to using the monitor with my laptop I do not have this option, and it is too bright to be usable. Also, there are very faint diagonal (almost horizontal) lines running across the monitor, about an inch apart.
Is there any way to fix this? My monitor has two input cables (for use with two separate machines), and both of them have this problem, so the problem does not seem to be the cable or the machine. The only constant is that I am using a vga-dvi adapter (since the monitor cable is vga). I did try using different adapters but the problem was the same.
