Okay, Teeming Millions. I own an ordinary laptop with an Intel 915 GM/GMS screen. I also own a pair of sunglasses. When I am at my computer and wearing my shades, should my head tilt to the left (my right ear above left ear), the screen will start to darken, and as I tilt my head it will get darker, and then start to get lighter again as my head reaches a painful 90 degree angle. If I tilt my head left, this doesn’t happen - in fact, it gets lighter to a point.
Now here’s the wierd part. I also own a flatscreen LCD TV, and as I tilt my head right while wearing my shades (my left ear above right ear), it gets dark! What gives? Why do LCDs do this?
