I have an Iiyama Prolite E435S monitor which gives a pinkish colour unless I press the Auto/Exit button on the monitor. It then reverts back to normal colour for as long as the Auto Set-up message appears on the screen, then goes back to the pink hue again as soon as the message disappears. I told Iiyama about this problem and they replaced the monitor. The new one seemed ok, if not perfect, for a few weeks then started to behave exactly the same as the one it replaced. It's connected to the pc via D-sub. The pc is based on an Asus 400 board and AMD processor. Any ideas??
