I have recently purchased an Acer AL2671W and have a problem. When viewing anything through a SCART or composite input (ps2,freeview) there are two pixels stuck on bright green in the centre of the screen. When viewing through the VGA input or aerial input the effect is a lot less severe. On light backgrounds it looks like one pixel stuck on red. On dark backgrounds it looks like one pixel stuck on green. Sometimes the pixel disappears altogether. To my understanding, I thought that when a pixel was stuck it remained one colour regardless of the input. Can anyone clarify this?
