BTW… it's worth mentioning for those who don't know but xPands are vertically polarized so they will have the same problem as all the other non-JVC glasses if your screen material maintains polarization. To my knowledge only JVC glasses are about the only horizontally polarized out there. My Seymour CenterStage XD material does not so it's of no issue for me (but I'm not a screen expert so you'll have to research this aspect of your screen to know which one's will work for you (i.e. - are you stuck with only being able to choose the JVC's for 3D… IDK)).
I've been interested in alternate glasses to compliment my existing pair of JVC glasses as well. I had been eyeing the Xpand X105-RF-X1 glasses myself and I emailed Xpand specifically regarding the polarization. Here is my request:
"I'm looking for some Xpand RF glasses that feature RF and horizontal polarization on the active shutter lenses to use with my new projector. The X105-RF-X1 glasses look like they may fit the bill although your site doesn't list compatibility with my projector band. Can you please confirm if they are horizontal polarization? I've heard they may be ordered with horizontal or vertical polarization so I want to ensure I get the ones with horizontal polarization.
BTW, My projector is the brand new JVC X500 projector. I've already bought the JVC RF emitter and two pairs of JVC branded glasses at >$140 per pair. I have x kids ages x to x that I'm seeking cheaper options for so the whole family can enjoy. FWIW, the X105-RF-X1 glasses look identical to the JVC glasses I bought minus the logo, which I'm hoping is the case."
"All our glasses have vertical polarization, because all TVs and projectors have vertical polarization. The only exception is JVC, because they use horizontal polarization.
So, while X105-RF-X1, and B104 models will work with your projector, because of polarization you will experience brightness loss which is less than 10%, so not noticeable for most human eyes.
I understand that you don’t want to pay that much for the original JVC glasses (which we make that’s why it looks identical but polarization is different), so I suggest the best way for you would be to buy for your kids B104 models. They will not notice brightness loss anyway, this is for professional eyes.
And also please note that B104 comes in different sizes including Kid (!) size! So, you can get for your kids B104SX1, or B104SX2 – difference between those two is in color, one is red, the other one dark blue. So for girls you can get red one, assuming that you have girls
It sure feels like JVC and Xpand struck a deal to just pull compatibility off their website...
I have read that it is possible to order them with horizontal polarization instead of vertical polarization--at least over in the UK; however, I haven't found a place to order them that way. I was reading in the screen polarization thread and realized that I, like Krichter1, am using a screen that doesn't retain any polarization anyway so I don't think it matters whether the glasses are horizontal or not for those of us that fall into that screen camp. As such, I ordered two pairs of Samsung SSG-5100GB glasses from the Jungle for less than the price of one pair of Xpand X105-RF-X1s to try out for the kids. On my Seymour screen I couldn't tell much difference between the Samsung's and the official JVC glasses. I my brief 20 minute comparison, I think the JVC glasses might have been ever so slightly brighter and richer on color, but that just be my mind telling me they should given I could have bought 7 pair of the Samsung for the price of one pair of JVC glasses.
For anyone considering the Samsung glasses, consider the following:
- They are not rechargeable. They take a CR2025 lithium button battery that is supposed to run for 100 hours or more per battery. The batteries are cheap but if you forget to turn the glasses off you're going to chew through them.
- The sides of the frame do not fold in. They are very flexible and very light but you can't just fold them up and put them in a case. I keep mine on an empty shelf in my rack.
- The actual height of the lenses are shorter than the JVC glasses. The image on my 142" diagonal 2.35 screen barely fit comfortably within my field of view at a distance of 13'. I preferred the additional real estate of the larger JVC lenses; however, for smaller heads/children I think they work out great. Half of my kids preferred the Samsungs and half preferred the JVC glasses for fit.
Unless I learn about some more compelling options from other users in this thread I will probably order up a couple of pairs of Xpand X105s for adult guests and a few more Samsung 5100GBs for the kids.
