I will probably get a VW90 instead of a JVC. I made a table with pros and cons, and after removing ties and taking the winner of each feature, I ended up with this summary in the end.JVC Winning features:
Great On/Off Contrast without iris artifacts
Can take advantage of the polarization with a special screen
RS50 has much better CMS
RS40 (+2 glasses, emitter) cost 3k$ less than either RS50 or VW90
No degradation of contrast over years based on anecdotes ??VW90 Winning features:
Better ANSI contrast
Better on/off contrast with iris ??
No lag caused by the Video Processor (required for gaming)
High 3D refresh rate (no 96Hz flickering)
No motion color fringing, banding, dithering, noise ??
Sub-pixel zone convergence
3D Pupil Distance adjustment
Sharper lens ??
3rd party glasses compatibility
Available next week
No handshake issues with the latest nvidia cards ??
No lamp out-gassing problem every 100h ??
Many assumptions denoted by "??"
