"A couple of months ago I bought a 17" LCD monitor (PolyView V17E). However, when I first powered it on, the thing that struck me was just how bright the blue power LED was! This power LED is just next to the power switch, immediately below the screen itself. The LED was bright enough to be very distracting, to the extent where it was just too bright to be able to look at the bottom part of the monitor without needing sunglasses.
Luckily, the LED was shining through a small plastic diffuser, mounted in the case, which had a flat surface on it. A couple of coats with a permanent marker dulled the brightness sufficiently to allow me to use the monitor without being blinded."
