My friend was using his Nikon DSLR and had his polarized lens on his camera and when he adjusts it the screen of both new MB and MBP goes black, even on full brightness. He says this means they are polarized, is this true.
 
Yep, that's how LCD displays work, they pass light through two polarizers ( and a colour filter 0 that are set to not pass anything, and inbetween have a layer of liquid crystal that twists light passing through it depending on voltage, allowing it to adjust how much light comes through each pixel, thus adjusting the colour level.
 
Thanks for the replys. I'll tell my friend this, you really do learn something new everyday :rolleyes:.
