3D glasses & ghosting

I have the Samsung 5150 3D glasses, viewing with a Sony 4K 300ES. I find there is alot of ghosting in the image. Are some 3D glasses better at handling ghosting than others?

------------
The Samsung 3D glasses might not be compatible with the Sony projector. That's why I prefer to buy same brand 3D glasses. I use Sony Play Station 3 3D glasses with my Sony 40ES. Don't see any ghosting on the latest 3D movies I own. I saw some ghosting on "3D Ravities" blue ray disc, but those 3D clips are originally made in Years 1920's.
Play station 3 3D glasses are cheap and you can find from Amazon. It should be compatible with your 4K Sony. I paid $7 per glasses. You could try it. If not good, return for refund.

Active glasses tend to exhibit more crosstalk (ghosting) than passive glasses on non-DLP TV's & projectors.

The only way to really go crosstalk free is with DLP.

One feature that tends to help with my Samsung is turning on Cinemasmooth. There's less crosstalk than watching without it. I'm not sure if your Sammy has it or not.

Are passive glasses as effective? I'll try some motion flow settings on my Sony, thanks.

I think, it may be in this order, others may have different opinions, I haven't tested them all, just from what reviews I've read:

Active LCD - Passive LCD - Active Plasma - DLP. I agree that DLP is the best at little to no crosstalk. With the BenQ 1070, I hardly ever see any crosstalk anymore and I mean pretty much never.

This line intentionally left blank.

1) As long as you look at the passive 3-D TV at an even level (don't stare at the TV from above or below) passive glasses shouldn't give you any crosstalk.

Unfortunately, all passive TV's halve the vertical resolution to show passive 3-D. So if you have a 1920x1080p TV, watching passive 3-D means you'll be watching 3-D films at 1920x540 instead. This halving of vertical resolution is especially apparent on CGI 3-D titles that use a lot of diagonal lines. This shouldn't be an issue on 4K TV's though. Unfortunately, most 4K TV's that support 3-D still use active glasses instead of passive.

2) Motion-flow sounds like a frame interpolation feature.

Cinemasmooth simply repeats the frames. No interpolation is used. Cinemasmooth operates the Samsung TV at 96hz instead of 60hz. In 2-D, each frame of a 24fps movie is repeated 4 times a second. I'm not sure if Sony has a similar feature or not.

Generally, ghosting is your display's fault, and very rarely, the glasses fault. LCD TVs can't change the pixels fast enough, and plasma TVs pixels retain their previous image too long (so the previous eye's image bleeds over).

You don't need a 4K projector.
You could use 2 lesser 1080 projectors with Omega passive 3D set up.
No ghosting because each eye gets its own signal

$10k projector with ghosting and active glasses that cost $100.00 good luck having your 10 friends over.
It better be a great movie for the cost.
Does anyone know how much 4k content there is out there?? Sounds like some more research should be done.

The future of television and projectors is vast and wide open, hopefully a common thread develpos, so I can stop watching movies on my 4" cell phone.

I can watch whatever I want because mine can go in the dishwasher.

Just for safety purposes, considering all the greasy sausage fingers that inevitably smudge your 3D glasses.

ahem...DLP projector, no ghosting. The system uses two Optima DLP projectors...


DLPs are known to be ghost free. Passive or active, it won't matter.

That's great to know.
DLP is made by Texas Instrument.
Omega Optical is based in Vermont. But what do US states have to do with it ?

--------

Ghosting does not work in the same way with passive systems than active systems.
With passive systems you can use any type of projector you want, ghosting is tied to the filter system you use.

I have a dual projectors 3D setup. I have tried both polarized filters and the Omega filters.
Each has advantages and drawbacks.

The Omega filters do have an exceptionally low ghosting
When you put the glasses on, the ghosting is zero. (yes, no joke)

The issue with Omega is colour accuracy. The colour accuracy depends on the output light spectrum of the lamp and projector. Omega requires a projector with an light spectrum as wide and as smooth as possible.
There are 2 versions of the filters designed for Xenon lamp single chip DLP projectors or Xenon lamp LCOS projectors. The further from these configurations your projectors are, the less accurate the colours become. And then each individual projector make and model has some particularities that will affect the colour and are not documented by the manufacturer or reviewing sites (basically you have to try it to know whether if works well or not)
If you go to the Omega Optical thread you'll see people reporting on how well the system works for their particular projector.
My projectors are Epson 3LCD EH TW3500, the european version of the Home Cinema 8100, colour is not very good with Omega filters. So I switch back to polarized most of the time. (because I already have a polarized system and silverscreen)
From what we've learned so far : consumer DLPs have wider and more balanced light spectrums and usually work better with Omega.

Passive 3D, forever !
My Full-HD dual-projector passive polarised 3D setup. (really out of date ! I need to update it some day...)

I'm using a Epson 5020- active projector- on a 133" screen. I get virtually no crosstalk. However, once, I tried some non OEM glasses to replace a pair of more expensive OEM ones. I got terrible crosstalk. I paused it on a scene where this was happening and switched to an OEM pair, crosstalk completely vanished. Made a believer out of me about how much difference the glasses can make. I will now only use the Epson OEM glasses which are expensive, but excellent.

I've got an Epson 3100. Sadly, Epson brand glasses made no difference what-so-ever with crosstalk here versus two other brands I've tried. It sounds like MonsterVision glasses had adjustable timing that would get rid of crosstalk on just about any TV they worked with, but sadly, they do not work with Epson. I don't know why no other glasses have thought about having an adjustment for signal delays and shutter timing to help get rid of ghosting.
