I'm surprised that so many people don't have masking on a 2.35:1 screen. Even movie theatres have curtains that handle masking. I'm perhaps a-typical, but masking was part of the consideration when I was designing my home made 2.35:1 screen, not an after thought.
My screen frame is aluminum. I wish it had built in magnets. I already have the velvet.

If using an AT screen, then make a frame and cover with black AT fabric. In a light controlled room, it completely hides the un-used portion of the screen.

Seems easy enough to make the panels but how do you attach the panels if not using magnets?

You can use velcro tape squares if you have a frame that can accommodate it. I have velvet covering pink foam board which I attach to the bottom of a 16:9 for 2.35 films and use lens shift and zoom to move the image up. Makes a huge difference for complete immersion.

You could also use Gatorboard from a craft store covered in Protostar material, with Velcro.

So shortly I'll be getting away from high power to go acoustically transparent. I've always used the cheapy Samsung 3D glasses for $20 a pair. Will I need to get the $180 JVC glasses now, or is there a cheaper alternative?

The more things change, the more they stay the same.

I've wondered the answer to this for a long time. I use the cheap Samsung's too. I think I'd benefit from a larger, lighter lens and side light blocking.

I've tried the Samsungs and the Panasonics; personally, I prefer the Panasonics (despite the ridiculous price) because of the side light blocking.

One thing I have noticed, is that the flickering effect is dramatically reduced if areas aside from the image on screen are visible - since they are not flickering at all!

The effect is reduced if you block the sides of the glasses, just as Dreamliner said, but it is also reduced if you have no ambient light and black walls and ceiling. I think if you are viewing in a total bat cave, the flicker would be almost noticeable.

Personally... I love 3D on my RS46, and I suspect that my viewing environment has a lot to do with that. I've never watched a sequential 3D TV set in a typical lights on living room environment, but I'd have thought it would be a nauseating experience.

Quite why Samsung designed their glasses the way they did is beyond me. I guess it's just a classic case of form over function.

My room is total black but light from the screen still fills the room. Quality increases when I block the light on the sides. What Panasonic glasses work?

I thought about making side blockers that would slip over the frame. But I've read the JVC glasses are a bit different in their lens tech, so I think it might be a good idea to buy at least one pair.

I prefer the jvc glasses for the first 20-30mins, then they become too uncomfortable.


I've only watch 2movies in 3D all the way through, both times I switched to the samsungs that came with my f8500. they definitely lack in lens size and blocking your peripherals, but I watch in complete darkness anyway, so that's largely negated. I wouldn't want to use the Samsung glasses with my f8500 with the lights on though. ambient light viewing with them would probably drive me nuts.


never worn a pair of active glasses I didn't generally dislike though. you'd think for 20-200bux they could afford 30cents for some nose pads at least... I mean if I have comfortable sunglasses that cost 5bux, then it should cost more than an extra 5bux MAX to make 3d glasses comfortable too.

So... no alternatives to JVC glasses when not using a high power screen?

I don't know what screen you use. Last I'd heard you need the jvc glasses if you have just about any screen besides high power.

It's not the gain of the screen that matters, it's how much polarization it retains. Unfortunately this is not a number you'll typically find published with the screen specs.

If the screen retains most of the polarization, you need the JVC glasses. (Otherwise it will be very dim.) If it retains none of the polarization, any compatible glasses will work just as well.

I seem to recall someone had a line on some Xpand glasses with the appropriate polarization. (Xpand manufactures the JVC glasses, but most of the Xpand-branded glasses have the opposite polarization.)

Right polarization, couldn't remember the term. According to this thread the Seymour at XD material retains 0 polarization so I should be good!

Discussion - Screens for 3D Projection

It does not mention the uf material unfortunately. Trying to decide between the XD and UF materials. Polarization could tip the scale though.

I'll be happy with 4500 Lumens 4K 3D with passive glasses.

Should be enough juice to blow through any glasses dimming while retaining correct color etc.

3D looks great to me in IMAX, at home...its okay. Best is still Avatar. Though some of they day scenes in Amazing Spider-Man 2 look pretty great in 3D! (Fight scenes with Electro look great too).

neither is anything special. one came bundled with my first projector(I've actually painted over the brand name and can't remember it, something with 'screen' in it), and the second is a uber cheap screen made by 'visionhd'.


I'd heard about the issue with the jvc polarization, but thought it was rare that a screen caused an issue with it, not the norm. all I know, is I didn't think I needed to pay attention to it at the time I read it, so I could be wrong.

Anyone know how to remove/delete Lens Memories? There seems to be no way to do it as far as I can see within the menus. Thanks.
