Yes, and I'm probably the best to give advice on 3D due to the amount of various monitors I've owned, plus I never get emotionally attached. If I buy something and it's rubbish, I'll say it's rubbish and vice versa.
Just to put you in the picture
I've had....so far
Samsung 23" Gen 1 Active 3D Nvidia
Samsung 46" LED Gen 1 2010 Active 3D
BenQ XL2420T Gen 2 Active 3D Nvidia
LG 47" WL650T Gen 2 Passive 3D
LG 23" Gen 1 Passive 3D AMD TriDef
I'm a huge AV geek and spent many hours with all the new 3D monitors and TVs
My advice for PC 3D Gaming.............give up on the idea
Games are not ready, Active technology gives headaches and darkens the image even with Gen 2 Nvidia lightboost. Passive 3d (as of right now) requires extreme angles of viewing and suffers from terrible crosstalk.
Basically it's too much faffing about.
3D for movies on the other hand is awesome with the new passives.
If I was you, I'd wait a few months to see if the new Gen 2 Passive LG monitors gets released. If it's anything like their TV, it will be a winner.
