Hi,
I am using an Lenovo 3000 V100 Laptop with intel i945 chipset, the 
build-in display has 12" and can display 1200x800 when I attach my LCD 
to the Laptop (22" using 1650x1050) I get to lines with faulty pixels. 
They seem to "belong to an other area of the screen since the change 
colors when I move windows on the desktop. This behaviour is 
semi-reproduceable since it happens on a regular basis but I seems to be 
completely random (sometimes there are no errors at all). It appears on 
screenshots as well, so I am quite sure it is not a hardware issue, I 
will attach a screenshot to better describe the error. Please let me 
know if you need further information.
Thanks,
Sebastian
