Any deals going on additional 3d glasses?  I've googled around looking for the Panasonic 3d Avatar pack but no luck for any stock.
Thanks

got a feeling too late on the avatar packs, this thread here appears to be a chance to grab some glasses cheap,

If you can wait a few months for avatar the latest 3rd gen are listed here Nathan if you only need a pair;

or earlier ones that are not as bright but still compatible presumably;

unfortunately 3D is something I avoid watching due to how it effects me.

Just found out these latest 3d glasses have a slider to convert 3d back to 2d Crist ; may come in handy with family viewing ?

edit Als link also lists the 2 pair 3rd gen glasses ;good deal

I have the pana 3rd gen ones cwt, TY-EW3D3MW, unless mean some others. all the slider does can see is switch the glasses on/off ie switch on for 3D switch off for 2D. unless there is some other slider someplace ! or some newer glasses again with that feature !

Thats the ones referred to at avs Al afaik ;someone mentioned the sony ''simulview'' feature and it not working properly ;then the panasonic was mentioned. possible the dinky slider switch has another stop position   its there somewhere..

ah ok I understand now. had another look at my glasses. which are same as in the link there. bascially you slide them from off to ON. then if keep slidding the switch its spring loaded and every time you slide it to its extreme it swaps between 2D and 3D. its a good feature by the sound of it. I'll try it on some 3D material next time I watch. Crist I would say if works could be a handy solution to join the kids and watch in 2D while therye watching something in 3D anyways I'll confirm.

2D to 3D switching function
This switching function is convenient when, for example, a group of people are watching 3D images and one person decides to take a break. When the switch is set to 2D, the images that you see with both eyes through the 3D Eyewear consist of the data for only a single eye's image. To watch 3D images again, you just flip the switch, giving everyone more flexible viewing options.

Hi Mark
Did you get the convergence controls to work in the service menu?
Did it fix the mis-convergence issues?
I also have red out by one pixel vertical.

The ONLY way to adjust "convergence" in a digital projector is to physically adjust the position of the imaging chips in the light engine relative to one another. The electronic adjustment uses adjacent pixels to correct color fringing but this is nothing more than a blur effect not true convergence correction.
Convergence is either good from the factory or it isn't, the user can not adjust it.

...With a white screen in a normal room (not a black painted bat cave) reflactions are a serious limitation on performance, the projector cant do anything about that, a clever screen can.

Can you help with 110" pull down (maybe motorised) screen options that help reduce reflected light?

Thanks

suggest create another thread on the topic, am sure be plenty to make suggestions. especially those maybe actually seen any of these screens in action. otherwise a question like this not really related to the epson pjs will likely be lost a bit here. suggest if can head out try seek out these kind of screens to check out for yourself to, nothing beats seeing with your own eyes

The only "3D" I've tried so far is the Foxtel Side by Sid format in the 3-D HD sports channel but the projector does not recognise this when the 3-D mode is set to "Auto" but works fine when I set it manually to "Side by Side".  Any suggestions why Auto would not work?

FYI - both HN and Bing Lee said they could order in the Pana 3D Avatar Started pack so I orded one from Bing Lee ($239 so not a great price but better than buying the bits on their own)

Ticked me off too jmone;you would think it easy to read two 1/2 horizontal resolutions plastered together with the sources edid May contact epson and see if a firmware upgrade is coming now youve confirmed it

Thats one other thing I was going to mention munners I was expecting it to switch to side by side as it says in the manual for a 1/2 frame rip of piranha [when set to auto] .Dug into the menu instead..

That avatar price is pretty good considering the extortion disc price on ebay and the panasonic glasses on top .Avatar exclusivity is sposed to end soon

Hi All,

Just finished watching Hugo on 3D Blu-ray - it's the best yet and has surpassed my previous 3D favourite of Pirates of the Carribean 4.  It truly is reference material.  My advice is to grab it as soon as you can.  I still can't believe that just 10 years ago I was watching a 21" TV and now I'm able to sit at home and watch movies with picture quality this good and in 3D!  I love it.

Phil

interesting to hear phil, yeah pirates was stunning, cant wait for hugo to come out here to grab it. sounds like a stunner. yes amazing isnt it this level of PQ and 3D at that is possible in the home

Just watched the new tintin movie in 3d on the tw9000 brilliant! (disc from u.s. mate) . The motor bike chase scenes are very cool. The best 3d I have seen so far. Tron legacy is also very good.

Well my new epson Tw9000 failed with blinking red lights today. The manual says it is an internal error. Has any one had any luck with Epson Warranty?

Q on the "Convergence".  I used the test pattern from here http://www.pbase.com.../image/77579988 and find on my PC that the Top Left looks OK but all four are out by a pixel by the Bottom Right.  The only thing I can think of is that the Lense Shift impacts this due to my PJ location which (relative to the centre of the screen) is High by about 25cm and Right about 50cm (as you look at the screen).  Other ideas?

yes as suggested, worth powering down completely, unplugging from power socket leave for a while and then power back on again. worth a shot prior to ringing epson support or taking to service centre. service can be pretty good, if just a small known issue the local melbourne centre depending on workload might even fix on the spot while you wait. otherwise pretty quick turnaround next day or so. if something more indepth having to go to epson etc can be weeks theye pretty slow. so good luck.

yeah not clear really. why is your pj up one side 25 mm more than the other. why not just level it out ? it does have level adjusters otherwise pack up and make sure with spirit level. or if using a mount adjust from there. Id make sure projector is perpendicular to screen and level in both directions, I wouldnt be using any projector controls to try to make up for projector misalignment to the screen

[Owen]

Remember a "pixel" is made up of three sub pixels, Red, Green and Blue. On a flat panel or CRT TV these three sub pixels are placed side by side in rows on the screen surface, therefore they can never line up and will be out by as much as two thirds of a pixel depending on the colour being displayed . Fill factor (the illuminated pixel area compared to the unilluminated black area surround the pixels or sub pixels also varies with colour. With a single pure primary colour (say red) displayed less than 30% of the screen area will be illuminated the rest will be black for a "fill factor" of 30%. The ideal fill factor is 100%

With projection the three sub pixels are projected on top of each other, this is obviously a much better situation than with a flat panel as fill factor is constant with displayed colour and is very high, 80 to 95% depending on the technology, with LCoS being the best and LCD typically the worst.
Chromatic aberration looks very similar to miss convergence but is a lens issue. It will vary with lens model, zoom and shift settings and be inconsistent over the screen.

Convergence also varies over the screen area and can change as the projector warms up. The pixels on the three imaging chips are tiny so even a miss alignment of 1000th of a mm is significant once the image is projected on a large screen viewed up close. If the imaging chips are misaligned (converged) from the factory it can’t be corrected other than by replacement of optical engine or projector.
Even with perfect alignment chromatic aberration is still an issue.

Video has no useful detail at the pixel level, everything is very very blurred (or should be in an ideal digital system) so don’t get too worked up about convergence errors or CA. As long as there is no visible colour fringing at your normal viewing distance don’t worry about it.

Thanks Owen - for the deatils and it was along the lines of what I thought.  I did try the service menu for the pixel calibration and it sort of works but appears to just "blur" it together.  It is worth noting that these issues really only appear in a test pattern when you are up close (that said I do get an impression of these areas of the screen to be much more "soft" in it's focus).

Applogies if I was not clear in my setup.  I'm trying to convey that my PJ is not in the "Perfect" position pointing directly at the the middle of the screen but while it is perpendicular to the screen is off set vertically by 25cm and horisontally by 50cm.  This is not an issue as it is well within the spec of the Zens Shift to still delivery the image in a proper rectangle but as indicated by owen I'm sure it leads to some convergence issues.

Lens shift won't affect convergence, but can have an impact on chromatic aberration (the internal lenses acting like a prism to split different wavelengths).  CA will often show up as a violet fringe and will often be worse on one side (and usually worse closer to the edge).  Use of horizontal lens shift is often a factor in CA.

If the convergence is out one (or if bad, two) of the primary colours (red, green, blue) will be out of alignment and create a fringing affect.  Convergence can often be uniform across a screen but may be variable across different areas.

When you say "all four are out" what do you mean??

[jmone]

I've packed it away for now, but the bottom right of the screen is where it is the most noticable on a test pattern.  There is both a Purple fringe + the four lines of the test pattern forming the square don't quite meet up cleanly like it does on the Top Left where the lines are neat and white.  I'll reset the pixel shift and see if I can take a photo (easier than trying to describe it).
