3D Vision 2 glasses contrast ratio?
What contrast ratio have 3D vision v2 glasses? I plan to buy for 3DTV Active 3D glasses and want something with similar contrast ratio.

It's my understanding that you typically can't use 3D Vision glasses with 3DTVs, you'd have to use 3DTV Play and whatever glasses the 3DTV uses... there are some older 3DTVs, like my Mitsubishi DLP, that were 3D Vision capable and can use the 3D Vision glasses but I can't remember reading about any others, except possibly DLP projectors.

I know, that's why I ask what contrast ratio they have and then I can buy similar universal bluetooth 3D TV glasses.

How bad/good are glasses with 750:1 contrast?

If the specs of the 3d vision glasses are published, I can't find them. But I only googled for a minute or two. 750:1 [i]sounds[/i] good, but I don't know enough to say for sure.

I googled too and didn't find any info. But I found some Philips 3D glasses even have 4000:1 contrast ratio glasses, but seems like they only work with active Philips TV. http://www.supportforum.philips.com/en/showthread.php?6143-Question-What-contrast-ratio-do-the-active-3D-%283D-Max%29-glasses-have Seems like 750:1 is weak, but most of glasses what I have found have 750:1 or 1000:1.

Open a support ticket, ask NVidia directly

Seems like I can't open support ticket, because I don't have some kind nVidia product membership code registred. I only can subscribe.

Do the glasses really have contrast? Aren't they just like a greenish filter (compensating the slight purple tint of Lightboost that some sites reported)? I would have thought that contrast just depended on the monitor. Unless the flickering that reduces brightness somehow darkens bright colors and keeps dark colors mostly the same, making the max brightness / min brightness a worse result. (I think I've just answered myself, lol).

I hope you are right. Because there isn't many active 3D side closed glasses(something similar desing like 3d vision kit glasses) with rechargable battery on market anymore. But that's weird why many 3D glasses have marked contrast ratio? http://www.ebay.com/itm/Active-Shutter-3D-Glasses-HDTV-Blu-ray-Players-Bluetooth-Signal-For-Samsung-P22M-/401050676415?hash=item5d607bacbf:g:jrEAAOSwKtlWi3tz I like this desing but it only have 750:1 contrast. What you guys think about that? Bad because cheap china? How much affect glasses 3D quality? Does TV is more importand for good ghost free 3D or bad glasses can make ghosting too?

I think you should first get a display and then worry about what works with it. You mention Blue Tooth glasses, but those will not work if the emitter uses RF or IR. There is certainly such a thing as bad glasses, the Viewsonics PGD-250 DLP Link glasses were garbage. But most of the glasses work as intended.

Today all active TV-s use RF(bluetooth) glasses and because that all 3D bluetooth glasses are universal only old TV-s and 3D vision kits use IR(infared) glasses.

Hmm that's good to know, they should have done that from the start. Of the displays that I have, only my Samsung S23A700D uses Bluetooth. I'll have to see if I can find some universal rechargeable glasses to use, I don't care for the button batteries and haven't used it since my last battery died.
