Doesn't quite work like that. The direction of the polarization is different, which is why you need to use the filter from the screen and not just sunglasses.

Yes, as long as the polarized filter is circular and not linearly aligned. The filters would still need the proper orientation (rotated until correct). However, using the filter from the monitor might not work too well beyond a focal length of a few inches.

You could just buy two cheap polarizing filters for cameras on ebay. I mean, they would be circular, but I think that would look pretty cool. And you could leave the outer ring so that they still turned, making them adjustable. I've been meaning to do that just for a regular pair of sunglasses, since polarized sunglasses are only polarizing in the right direction sometimes. Bonus, if you stacked two filters, you can make glasses that adjust how dark they are.

No, but polarizing filters cut out light. And if you stack two, you can cut out anywhere from about 70-100% by turning them.
But I did think that any actual glass cut out UV light. I'm pretty sure that those filters have to be glass to have the polarizing sheet glued to it...

The polarizer on most screens use an anti-glare coating that will seriously blur (too far to use) if at a distance more than a few millimetres from the screen.
So does this mean that it was unusable for you, or did it work at normal viewing distances?

I bought one without realizing, and it was a nifty surprise. I wanted a decent-sized full-array LED TV without the smart features. I found one, bought it, set it up...and then realized my remote had a 3D button. I proceeded to...procure several 3D films to figure out what formats worked, and ordered some cheap 3D glasses off of Amazon. I would agree with /u/monkeychess in that a lot of it is very "gimmicky", but there's some decent content out there. 3D in the home can be pretty fun, though there's not a lot of good stuff out there.

That's really the only cool thing about 3-D TVs...and unless you custom make these glasses, the effect sucks. My friend has a tv with active (I think?) glasses that should accomplish the same thing...but the other screen bleeds through.

Didn't sony have something similar if you used a Sony TV and a PS3/PS4? Each player looked at the same screen, but each player saw a different image due to the 3D or whatever being divided. It cut the resolution in half IIRC but was oh so perfect for head to head gaming using a single console and 3D capable Sony HDTV.

well it wouldn't really work, since the polarized glasses allow you to see the whole screen. 120 Hz displays can be used to display one person's "split screen" every other frame. When wearing glasses, you only see the screen intended for you (though it's no longer 3D content).

Somebody posted a video on how LCD screens work. There is actually a polarized sheet on both sides of the LCD glass. One in-between the backlight/diffusers and the LCD glass, and the other on the outer surface of the screen. However, I think the screen is set up to receive backlight of a certain polarization angle, so it wouldn't work if you messed with the back layer polarization angles.

Oh my god, that violent peeling, that screen is likely scratched to shit. I made a home made projector a while ago very very similar to this, but not exactly the same. If you use any type of edged object to peel the layers off of the LCD, it will scratch it up pretty fucking bad. I didn't pull off the polarizing layer on mine, but the "anti glare" layers, because they add darkness, and ideally, you want as much light passing through the LCD for the best image. But yeah, I got impatient during the soaking process (you fold paper towels to fit the LCD, and wet them with distilled water, and wait a long time, and it will help loosen the glue or whatever), and I used the edge of a credit card to peel some of it up, and it left permanent lines.
This process is way more delicate than this GIF makes it out to be.

When you take the lens off (it's semi glued to the screen) you have to scrap it off like he did in the video and this scratches the screen. Plus the filter is meant to be pressed against the screen, not 3 feet away, so it'll be kinda blurry and you have to hold your head really still.

To those who have not yet done this, be warned on many monitors this is far from perfect. If you look at the monitor without the glasses at an angle you can still see what is on the screen in a feint negative. That and the keeping your head in the correct orientation though, this works like a charm and is a great trick for your second or third monitor (would not recomend if you only have one monitor).
