I have a 2407 rev4 and it does the same thing. I'm using the DVI output from an ATI Radeon 9600 graphic card. The blue dots and lines and the yellow splodges clear if I switch off the monitor and switch back on. They also go if I press the input source select button to toggle through the various source options and back to DVI. I'm just trying to figure out if this is a fault with the monitor or the graphics card (I don't have access to another monitor with DVI connection to try).

Does this occur on both the video card DVI and VGA ports?

Do they ever appear in the bios setup or safemode? If not, the issue is with either the video card driver or the video card.
