as far as i know 3d monitors don't require glasses (correct me if im wrong) but instead rely on two signals to transmit 3d-style picture. it modifies them and combines then on-the-fly, so the quality is less than an HD screen, but that should change soon. they might also have built-in graphics accelerators and they might require special cards. make sure that your 3d monitor/TV has both VGA and standard TV cable inputs!
I'm afriad your wrong
There are three different ways of doing 3d (There are more but not mainstream) and they all require glasses. There are 3d that don't require glasses but it's shite.
Anyway first 3d is what you get in cinema (in the UK anyway). It phases two pictures at once slightly out of phase on the screen. the glasses look seethru. It's gernally pretty good quality 3d but huge screens in cinema make it look even better ^^ It works with polarised glasses and the glasses are only a few quid. Far as I know it's only for cinema, being it's good quality and cheap but harder to do than red and blue 3d.
This replaced the horrible (imo) blue and red glasses. There are other colours used but blue and red are the most common. It works in a simular way as previously except differating the pictures by colour so only one eye can see the red picture and the other eye the blue picture. It is is generally the WORST 3d and is what you can do on ANY computer with 90% of all games!!! Yes I have tried it and playing uT3 or batman or tf2 in 3d is pretty cool. Sadly it is very limited, things aren't going to jump out of screen and touch you ^^
Then we come to the uber expencive completly amazing 3d that nvidia have brought out. And is also comming to TV soonish.
Basically you need a monitor with 120hz speed, allowing 60hz per eye. The monitors don't generally cost too much more than a normal monitor. You then need a £120 (Roughly) pair of glasses per person. The glasses are basically two shutters, that close and open EXTREMLY quickly, faster than the eye can see. They basically open and close so only the eye it wants can see the picture on the screen. And the TV is flipping between the picture for the right eye and the picture for the left eye in sync with the glasses. This costs the most, but will give you outstanding 3d pictures that once again can be used on about 90% of all games.
You just need to download a really small file and ta da, instant 3d all games. However I don't know if you can do this for ATI cards.
From FPS, I didn't notice a huge drop, but it does tax your graphic card slightly more.
If you are going to buy a new monitor and you can afford a 3d one, I would buy it ^^ 3d is the future and it's awsome.
*Edit* I was in a rush, just wanted to add, doing 3d does not effect your res on your monitor. You run the game just like you would normally, except nvida witch craft drivers suddenly makes it all 3d. So if you run games at 1900x1200, thats what it will be in 3d too. You don't need special cables at all, the 3d monitor are literally just a monitor with 120hz refresh rate. And for red and blue 3d, you just need any screen + the downloaded drivers. It literally takes 30secs to do.
On a side note, if you do try, you will have to go into the graphic control panel each time you want to disable or enable 3d. Otherwise every game you run is 3d or 2d. Kinda annoying but no big deal
