Review on 👓 Hi-SHOCK 3D Active Glasses Scarlet Heaven Compatibility Guide - Sony & JVC 3D Projectors VPL-HW65ES, 45ES, VW365, VW350, VW500, TDG-BT500A, X105-RF-X1, JVC RS 400 - PK-AG3, PK-EM2 by Ben Barrington

Although listed as for newer JVC projectors, these glasses do not have the horizontal polarization required for true compatibility. They are vertically polarized like most 3D glasses on the market. They sync perfectly and otherwise work well. If your screen does not retain polarization, these glasses are for you. If your screen manufacturer does not publish polarization attenuation values, you can determine if your screen is polarized: Use standard polarized sunglasses. Look through the lens of your glasses at the light coming from the projector (several meters away, don't burn your eyes!). Rotate the sunglasses, you should see a sharp change in the brightness of the projector light. If you do this, now use the same pair of sunglasses to view the JVC's projected image on the screen and rotate it 90 degrees again. If you see a change in brightness and color your screen is polarized and these glasses will not work for you. If you can't see the difference on the screen, these glasses will do. My screen retains very little polarization so I leave them on, the brightness is acceptable. How these glasses compare to other third-party 3D glasses: * Pros: These glasses are stronger and more comfortable than flat plastic glasses. They have dual color LED indicators and are conveniently placed to make them easier to use. They sync quickly and work great. They are compatible with 3rd party BT/RF transmitters. * Neutral: Once synced, these glasses work just as well as the brand I compared them to. No better, no worse. Same brightness, almost identical colors, same amount of flicker and crosstalk (very little with my JVC RS500 for example). *Cons: Slightly more expensive than the el-cheapo brand. If there was a horizontally polarized version of these glasses I would give them 5 stars.
