OK..
So nobody likes to wear sunglasses while wathcing movies but...
Rip out one polarizer form the LCD to allow double the light on the screen. Wear polaroids so that you can see the screen (Light back to standard level) BUT at the same time reduce ambient rom light by over 2x..

Sorry if its been covered already.

Cheers,
Kirk

I think that you might need a special screen to maintain the polarization of the light reflecting off of it. If polarization is maintained, it would definitely work.

How about removing the front polarizer from your monitor and putting it back together? Then only you, wearing polarized lenses, could see what is on the monitor screen.

The ultimate in computing privacy.

That would fix that idiot that is always looking over your shoulder. laugh.gif

Don't think so. Reflection from a viewing screen is at a very normal angle so its well below the Brewster limit. Polarization should be maintained I would think. This is similar technology as 3D movies and they seem to work fine. the difference being we need both eye lenses oriented the same instead of at 90 degrees to each other. It would be kind of cool because everyone else would just see a white screen. Very private! You would have to keep a level head though wink.gif

I think you’ll find that the polarization will become random after reflecting off a plain white screen. You can do a simple test if you have a pair of Polaroid sunglasses and an LCD monitor. Most of the light leaving a monitor is polarized so looking at it though the sunglasses while you rotate them you can block the image. If you place a sheet of white printer paper against the LCD the polarization is lost. I think the light reflecting off a white screen will suffer the same thing.
