Is there a future for 3D Vision? (the hardware version)
7 / 9
It's bizarre how little imagination all these manufacturers have. They could have made a 1080p projector at 120Hz years ago for gaming, even in 2D, but the only thing they can see is blu-ray movies. Such tiny withered imaginations. Look at what a crazy result came from the old WRT54G router with open-source. They sold 10x more than they otherwise would have.
Makes me think that it might be interesting to try something weird like a Kickstarter to rebuild the guts of a standard 1080p projector. The light path and bulb and cooling are all good, it's the communication and motherboard that are pathetic. Building a board to run linux and drive an output chip like a DLP is not exactly rocket science here in Silicon Valley. I personally know four people who could do this.
The point of something like a Kickstarter would be to gauge demand. Doing one-offs is pricey, but if you can get into the 100s board prices get pretty cheap. Dunno. Too many projects, not enough time.

Well I suppose incoming 4k projectors will be free of those wierd limitations. And "affordable" DLP chip supporting 4k probably will be inside projectors in a less than a year time. So probably no point in starting kickstarter campaigns just to get 1080p@120hz dlp :)

Here's a link to Acer's control codes for one of their projectors, thought you might find it interesting.

Teaxas Instruments has lots of documentation and whitepapers available. http://www.ti.com/
From what I looked at previously, each of their chips has it own accompanying devopment kit.
The Acer H5360BD reportedly uses the 0.65 DarkChip 3 DMD
Here's a link to the 0.65 1080P documentation

I had a hard time finding this post, but I know that there are a few of us using LED projectors that may the information on this page useful in the event of failure. I had originally thought that he also had a picture of his DMD under a microscope, but unfortunately, that's was someone else.

Well, that's not going to happen. I'm more patient than most people, but there is no way we are getting 4K projectors at decent cost in the next year.
Here is the absolute best DMD chip you can buy today, found by D-Man11's links:
http://www.ti.com/product/DLP9000/samplebuy
This is a 2560x1600 DMD, which would make for a fantastic projector. Unfortunately, in quantity 100, the chip alone goes for $2700. So, decent price 4K? Not happening for a loooong time.
Doesn't matter that much for 3D, although that would allow us to sit closer to the screen, or use it in 2D. Right now, my only real problem is that in 2D, I can see the pixels, and 720p is a small screen to use a computer. Bigger would be an advantage in 2D. Probably not worth the effort however, since I just found that 720p projectors are still viable and as good as ever.
Before you object that 4K projectors already exist- those are a different technology using LCDs, and are going to suck for 3D. DLP projectors are the only way to get ghost free images.

Yes, you are completely right that currently only DLP options for 4k are made of multiple DLP chips and cost a fortune. And other 4k options are actully LCD's and they are really bad for 3d. I myself have 1080p 3LCD and DLP projectors and ghosting on LCD projector is terrible, while DLP is essentially ghosting-free.
But what makes me hope for a affordable single chip 4k DLP - is this demonstration of a small 4k DLP chip by TI: http://www.displaydaily.com/display-daily/31418-ti-to-bring-4k-dlp-to-the-masses

So they are going back to what they were using in the Mitsibishi and Samsung rear projection DLP 3D HDTVs.
It took them long enough.

[quote="bo3b"][quote="bo3b"]Pretty sure that this H5380BD would work with an EDID override. The menu setup is identical to my H5360, just a slightly different look. It actually has a 3D Vision option in the menu, which I've never understood on the H5360, as I never needed it, and turning it on makes it miscommunicate. If the default mode is DLP however, this might make more sense to put it into 3D Vision mode, and be able to use 3D Vision glasses directly.
Not fully clear, but there is menu choice for "3D Vision", and as you know 3D TV Play is just DLP mode as far as the projector is concerned.

Got this projector and hooked it up. The short story is that it works just fine, for either 3D Vision, or 3D TV Play.
The answer to the question about the manual is that things are even more lame now than they were. The manual has not been updated for the new projector, which is why it's confusing. The on screen UI looks completely different, and is not documented at all. Gotta love that no one even bothers to have it make sense nowadays.
It only works as 3D TV Play out of the box, it's not a certified projector. You can't get into the menus to switch it, even though the manual says you should be able to, they are greyed out. 3D TV Play for both HDMI and VGA connections works.
If I set an EDID override for an H5360 projector, it goes back to working normally as 3D Vision, using 3D Vision glasses. No visual difference between this H5380BD and an older H5360, although this one is brighter because the bulb is newer. 120Hz works like you'd expect, and does not dim as much, or get slightly blurry like the H5360.
So... the answer to the thread is that, yes, there is a future for even the hardware. It's not labeled properly, but this projector is on the shelves today, brand new, and works exactly like an H5360. So, we are fine on the projector front for at least a few more years.[/quote]
Follow up on this projector.
The projector works OK using the H5360 override, but the blacks are washed out. Near as I can tell, this is the DLP flash, and it also gives a feeling of retinal rivalry, so I don't think this projector is viable for use with 3D Vision glasses. Should be OK with DLP glasses, but I don't have those, and would prefer to continue to use my 3D Vision glasses.
Anybody know of a way to disable the DLP flash? The on-screen menu in the projector doesn't do anything for this case.
If I leave 3D 'disabled' in the menu, then the projector works correctly for no DLP flash, but the eyes are reversed for 3D Vision glasses. I can't switch eyes, because it's greyed out. If I enable 3D in the menu, it works, but even when choosing frame-sequential mode, I still get DLP flash.

@bo3b
There could be something in the service menu. I have no idea how to get there with that model though. I believe h5360 is to press "power -> left -> left -> menu" on the remote while its on. Could be the same for your H5380BD.

The problem with using the H5360 EDID override is, that in most instances the eyes are reversed causing flat 3D and eye rivalry.
Did you try the glasses upside down or swap the sync in the PJ menu?
If you turn 3D Vision to "on" in the projectors menu, that should disable the DLP Link flash.
Also, Nvidia has always had an issue with supplying the correct Dynamic Range to Displays. If the incorrect Dynamic range is used, it will "crush" blacks. (wash them out)

H5380BD only has dlp link mode so you cannot turn 3d vision "on" in the projectors menu. Its either dlp link with flash that destoys the image, or off in which case eye sync is reversed with no option to swap the sync. I also understood that in that mode it worked fine as long as you kept glasses upside down.
So there are two options. Either find a way to disable dlp flash while 3d is "on" in the projector(no option in the pj menu), or find a way to correct the sync issue when 3d is "off" in the projector(sync option greyed out in the pj menu, driver level hack maybe required?).

Thanks for the info Sammy123.
I temporarily hooked up my Acer H6510BD and can confirm that it has the same behavior.
I've always just used the glasses upside down with any of my Projectors using the EDID hack, a driver hack would be nice.
Thanks for the info.
I tried the service mode, and it's the same key sequence for this projector, but nothing related to 3D in there. All very frustrating and stupid limitations. If either NVidia or Acer could just freakin' relax and let me do what I want, instead of locking out things to dumb them down, we would be able to solve all sorts of problems. NVidia locking the eyes and not respecting their own image setup (hex and triangles) is just stupid. If it's 'certified', you shouldn't have to worry your pretty little head about it.
I'm going to look into a driver level call that suggests it can swap the left and right backbuffers. Low probability, but I've wanted to look at that for awhile, and this is incentive.
