Acer Travelmate lcd shows all pixels twice in 2px distance

I have a rather tricky issue with my Acer Travelmate 5620 lcd.
The screen appears to be printing every pixel twice at a horizontal distance of 2 pixels. Image taken with a digital camera
I have already done the following troubleshooting:
- replaced lcd and lcd cable
The result is the same except for a black vertical 2 pixels thick line that used to show on the old lcd.
If I take a printScreen picture the error doesn't show. As far as I understand, this would mean the video card is correctly rendering the image.
However the error shows exactly the same way on the bios screen.
Where else should I look for errors? What would be the next steps in troubleshooting?
Thank you for your help in advance!
