Looking for a screen that retains polarization to pair with my JVS RS500, which utilizes horizontally polarization for its 3D. Brightest and cleanest 3D image is seen with using the JVC glasses and a screen that retains polarization.
Probably looking for something around 1-1.3 gain.. hopefully under $800
In the last few years, I have tried the following screens with high polarisation retention capability :
- XtremScreen Daylight 0.9
- XtremScreen Daylight 1.1 Reference (original version and the current version)
- XtremScreen Daylight 2.0
- Drapper React 3.0 (it's version 3.0, gain is actually 1.0)
All of them can be considered to have very high polarisation retention for active 3D.
Passive 3D is an other story.
All of them can be used for passive 3D but they behave very differently : they all have a very similar polarisation retention in absolute terms (same brightness of the crosstalk for the same source) but the visual result changes dramatically due to the gain difference. The extinction ratio works like a contrast : the brighter the signal image is displayed (due to gain), the lesser the impact of the same amount of crosstalk.
The higher Xtremscreen with 2.0 Gain looks just as good as any good silverscreen with low enough crosstalk for any movie to be perfectly enjoyable. I bought one for my passive 3D setup.
The lower gain screens are barely acceptable for passive 3D. They work... but there are lots of scenes in most movies where crosstalk is very visible and annoys me.
I used the XtremScreen 1.1 for a while, and I'd say this is my tolerance limit for passive crosstalk (it's an amazing screen for 2D or active 3D though).
I would not use the Draper React or Xtremscreen 0.9 for passive 3D.
I can't say about prices. You'll need to ask each manufacturer/reseller for a quote. They tend to be expensive (especially the XtremScreens since they have an excellent reputation and are a market leader in my country)
