Where are you guys buying these glasses from and are these the best/cheapest? Having owned LG 3D Tv for years, I'm not use to paying $100+ for 3D glasses
Check Dr Horribles article linked above. You have to email xpand directly.

It’s sort of random, where they show up.

Of course I went with the older IR emitter even though my jvc is designed for the RF emitter because the correctly polarized jvc glasses for IR were 1/5th the price of properly polarized RF glasses. So it was older stock, and even more likely to be overstock or b-stock from a liquidator. I found them on eBay and Amazon.

Do you happen to have model numbers for the IR emitter and the IR glasses? What projector are you using them with? Thanks!

I have an RS500.

I use "XPAND JVC X103 3D Active Shutter Glasses - a 2 X Pack of 3D Glasses" and now that I look it up, they were $10 a pair, from "SurplusGizmos.com, LLC (503) 439-1249" via eBay, two years ago.

I think I am using it with a "JVC PK-EM1 PK-EM1U 3D SYNCHRO EMITTER" which I also found on eBay for $60.

My notes are unclear so if you decide to go down this path with the older IR models, be sure you have the option to return them if they don't work for you.

(And of course IR is not as foolproof as RF. Need line of sight between glasses and emitter to get excellent sync.)

You really want to go with the RF emitter.

True. It is much less finicky. But since we only watch 3d on special occasions, the price delta made the tradeoff okay. Outfitted the whole theater for under $100 including glasses and emitter. But if we watched a lot of 3d, I would spend the $500 to go RF, for sure.

Yes, with need for 5 pairs of glasses if just my family is watching, the cost is pretty up there. Also, putting $150 glasses on kids (and especially their friends) seems a bit folly.

But getting IR line of site to a projector that is behind the seating position seems folly as well!

Will keep exploring the options. I know there are a few outlined in this thread.

FYI you don’t need line of sight to the projector. There is a wire that goes from the projector to the emitter.

I place the emitter above the screen pointed back at the audience. It likes line of sight between the emitter and the glasses.

Again it is finicky. But >90% of what we watch is 2d especially with uhd sources being common nowadays. So for us the hiccups are okay.

$500? The rf emitter is about $100. I guess if you want a lot of glasses the price would add up.

But if I had nothing, and was deciding, I'd go RF emitter, and for the JVC, pay the extra for the X3s.

Depends on how many glasses you need. We ended up with six plus an emitter.

If you need the polarized for JVC glasses like I do, that’s a choice between hundred dollar per pair glasses in RF and ten dollars for two pairs of IR glasses on close out. Since we don’t use them a lot, I could spend that money better elsewhere in the theater. Ymmv.

How did you get the emitter from back to the front? How long is the cable that comes with it?

Not sure. More than six less than 12 maybe. Enough to get in front of the seats and point back at the audience from the ceiling.

I just received the RF receiver with glasses bundle (from Amazon) and I cannot get them to sync. Is there a special way to do it?

I connected the receiver to the projector, turned on the glass then pressed and held the button until it was slowly blinking. After few seconds the glasses turn off and I don't sync.

Is there anything else to do to ensure sync and confirm that they are connected?

You possibly need the projector detecting a 3D signal so in 3D mode. So play a 3D blu ray. Just a suggestion. I've always had a source in to register.

I admit a lot of the glasses are so annoying to register or even turn on, especially in the dark when you are fumbling about.... The xpand button is so hard to use. The HiShock had the nicest. The Sony's are OK.

Thanks for the suggestion. I think I tried that as well but no luck. Will check again.

It isn't an issue with transmission? Eg the signal from behind the projector not getting to the glasses?

With a 3D BD playing and the red light on the transmitter, have the Xpand RF105 glasses near the transmitter and hold the power button for 10 seconds. Then tap it once quick and it should engage the initial sync. Once that is done, all it takes is a quick tap to sync the glasses for future viewings.

Thank you for the suggestion. It worked!

Several months ago I purchased an X5900 (uk) and found the 3D to be pretty good, I already had Xpand X105 lite glasses along with Samsung SSG3100 so just purchased an oe jvc emitter. This works perfectly on my non retaking basic white screen but tilting my head 90 degrees I could see a very small increase in brightness so I bought a pair of the horizontal polarising jvc glasses to compare.
Interesting results, as expected there was around 5-10% brightness increase so I was initially very happy as any small increase in 3D brightness is welcome.
However I noticed right away that there is a colour temperature difference between the xpand and jvc glasses.
As a background I suffer from neck pain and my preferred position is looking straight ahead or slightly down with my eyes looking slightly up at my screen, in this position the Xpands vertical polarisation give an accurate warmer colour temp. The jvc glasses with the horizontal polarisation in this same position give a colder colour temp which is not accurate but if I tilt my head back then the warmer colour tone returns but this is uncomfortable for my neck.

So the xpand 105 X1 have warm tone when looking down and cooler tone when looking up. The jvc has the opposite, I'm quite curious why this should happen and if you DIY calibrate you need to take this into consideration when fixing the glasses over the coloromiter otherwise greyscale will not be accurate if the glasses are at a differnt angle when wearing them.

Anyone else notice this ?.

Check Dr Horribles article linked earlier in the thread. You really need the rare expensive re versions, from xpand direct. JVC have some odd polarization and the standard 105s have polarization in the opposite direction.

It's not the darkening issue I'm meaning, I have the official jvc glasses with the horizontal polarisation, it's the fact that to keep the accurate warm colour tone with them you need to tilt your head back. Very odd.

Perhaps that’s why calibrators calibrate a separate 3d mode with the probe reading through the glasses on 3d content.

Other than line of sight being needed, are there other differences between the JVC IR glasses and the RF ones? I'm looking to pick up a few pairs of glasses and an emitter, and I'm leaning towards the IRs because they are so much cheaper and because I really won't use 3d all that much.

No, both the IR and RF JVC glasses have the same unique polarizer. With that said unless your screen really retains polarization your best option might be to find a cheap xPand RF solution. IR glasses are a pain with losing sync with any head movement with relation to the location of the transmitter.

Thanks for the reply. I'm getting a screen the retains the polarization really well, so my options are limited :-/

Do you happen to know how bad/finicky the IR glasses are? I was planning to wall mount the IR emitter, pointing down on the seating area from behind it (or does the emitter need to be in front). Would I still likely get syncing errors with light head movements in that setup?

Got it working sometime ago. Turns out the emitter was bad.

Also, you are correct the movie needs to be playing for it to sync.

I found it necessary to place the emitter in the front of the rom facing the audience.
