I have a HP P1100 21" monitor that just started scrambling the whole screen. I can see the desktop and all the color is there but it is just all over the place. I plugged the box into my wifes monitor and it was fine.
I assume it's cheaper to buy a new one overall than get a repair done. Anyone heard of this problem though? Be nice if it was a cable but I don't have an extra to swap in.
