DLP vs Projector vs Plasma Which one is best for 3D
Hi Guys,

Will be taking the plunge to go 3D, but I'm reading so much stuff, its hard to come up with a conclusion which one is superior for 3D.

The criteria:

- Going to be sat around 8 feet away from screen
- I really want a big screen. Constantly reading on these forums that bigger is better.
- Best for pop out, very little ghosting.
- and the most important, I just want it to be simple plug n play and it works. (This rules out Dual projection because after reading so much stuff about how to configure it, lens shift, type of screen etc...I honestly dont have the patience!)

Just to throw a few suggestions in there...

Mitsubishi DLPs- Heard alot of good things about it, no ghosting, cheap to maintain, and can get it in large screen size....However I'm not sure what resolution games will be in 3D when i play, anyone clear that up for me?

is this going to be better than the......

Acer H5360 Projector - alot of people are praising here however there are some issues about pop out not as good as a crt or lcd, which kinda ruins the experience.

The new contenders are these Panasonic Plasma TVs - Very high refresh rates (600hz), really high contrast....I've read an article saying that Plasma is the best experience for viewing 3D.

So guys, you all know its alot of money so thats why i really want to try and get this experience right first time. Anyone who has experience with these types of screens and products, would love to hear some advice on which one I should get that would fit the criteria.


Thank you for any input :)

It's a pity you ruled out dual projection since it indeed gives the far best experience of all homeachievable solutions today. It's true you need some patience to set it up but's no worse than everybody can do it. Since nvidia only supports their own solution nowadays, dual projection is of course no option for those who sets nvidiastereo first hand.
No matter what: Dual projectors is supported by just everything written for stereo except 3d-vision. For movies i use peter wimmers stereoscopic player (same as the nvidiastereoplayer but enhanced). For gameplaying you can use both iz3d and tridef drivers. If you have an old computer (winxp, 7900card) a very high percentage of old games is supported by old school nvidiadrivers. I play tombraider 2, alienvspredator2 with excellent results for instance + a few openglgames like doom3 and prey.
So: If you're curious about dual projection it's not really as difficult as it seems. Lenseshift is good to have since it enables you to use full resolution without digital keystoning reducing it. Myself i use digital keystone and rack up the resolution one step ahead the projectors native res. This effectively gets rid of eventual scaling artifacts but on cost of a little performance. Lcd's also works fine with it and in cases when using stereopol filters really kicks dual dlp's way behind. Such rig is also 4-5 times brighter than a dlp+shutterglasses rig...

Projectors are sweet, but their downside is you need a dark room, and they take a bit more setup that any of the other options. LCD are known to have ghosting and you will end up with a much smaller overall screen size.

As for the plasmas, the 600hz part is really just marketing mumbo-jumbo: if it has hdmi 1.4 the the tv will have a 120hz input and display at 120hz (60hz per each eye), or if it uses hdmi 1.3 it will have a 60hz input and display at 120hz using the checkerboard format. As for the price of these tvs, well basicly expect to pay for size.

For me DLP is the best way to go. They have the best $ per inch ratio of any 3d option on the market, except possibly a few budget projectors, they're bright, easy to setup, and have no ghosting. The only possible downside to DLP 3d is that the checkboard 3d format that they use is not the new official 3d format that was established (framepacking w/hdmi 1.4) so it will not be comatible with 3d ps3, or any other future device that will only adhear to the new 3d format, but as long as you have a powerfull pc you can add a blu-ray player for 3d movies.

I am personally running on a 67" Samsung LED DLP and I wouldn't trade it for anything...Well maybe for a full theater room with projection and a 120" screen, but um yea thats not going to happen unless I win the lottery.

Likay: I am very grateful you have replies to my post as I have seen your expertise on most forums now and you seem to know vast amounts for a Dual Projector Set Up. I am wondering if you be so kind to answer a few questions below for me regarding this set-up.

1) If I buy these two projectors [url="http://www.google.co.uk/products/catalog?hl=en&q=1080p+projectors&cid=5173971552999169703&ei=2osWTNB8g8TDBYvT7JwF&sa=title&ved=0CCEQ8wIwBTgA#p"]Acer H7530D[/url], it would mean it offers 4000 lumens in brightness in total. I know 3D reduces this, however this is surely sufficient enough?

2) This projector has no lens shift, but does have keystone correction. Reading your post, your telling me that there will not be a problem to align the two images?

3) Can you please direct me where I can buy a silver screen for this set up? One that doesn't show signs of crosstalk or ghosting, no hotspot etc. Basically a decent one. I really don't want to paint if I dont have to. Also filters will be needed that can withstand the heat, so can you please show me where I can get these linear filters?

4) I will be sitting 6-8 feet away from the screen. Realistically how big a screen can i get? 100inch?

I apologise for bombarding you with all these questions, but as you know, getting a dual projector setup is expensive so I would be very reassured knowing I have consulted you.

Redcubelilj: Thank you so much for your information on the plasma and dlp. I must admit the 600hz thing did sucker me in and I thought that was a very cool feature. I am really disappointed that DLP's wont be compatible with the new format, as I have a PS3. However maybe PC 3D gaming is all i need :) Fingers crossed for winning that lottery lol :P

i would go dlp projector or mits dlp tv, if you want to use 3d vision. check out iz3d or tri depth if you want more open ended software. but be aware its not as mature as nvidia. Nvidia has disadvantages- like limited display technology support- it has to be certified by nvidia to work. Hopefully with more mainstream 3d adoption nvidia will be forced to support more displays that can do 3d but dont want to pay for the certification. a single gpu 3d computer will do fine on iz3d drivers- but sli will not work yet nor will dx 10 or 11 games.

lots of info on how to brighten up the projector with custom screens. search is your friend.

the new plasmas lack 1080p gaming. not worth the price considering the lack of features.

there will be 1080p projectors someday soon buy only god knows when- im guessing by xmas- but thats just a educated guess.

the mits dlp displays in 1080p checkerboard. which is better than 720p but not full hd. your computer will be outputting a 1080p signal.

has the advantage of 1080p 2d.

with an ultra high gain screen you dont need to cover the walls in black, it works in broad daylight just as good as a lazy attempt with matte white screen in the dark.

1) If I buy these two projectors Acer H7530D, it would mean it offers 4000 lumens in brightness in total. I know 3D reduces this, however this is surely sufficient enough?
Yes it will be. The polarization of the filters will cut away 55% which leaves you with 900 lumens for each eye and screensize. My projectors are 2000 lumens in ecomode and even when using standard polarizers any shutterrig is left behind simply because of the more light. You may wish to dim the room using rollercurtains though.
If using shutterglasses plus an equal dlp you'll get less than 450 lumens/each eye because you get both polarizationlosses and the eyes needs to share the remains. Most people don't know that using shutters result in a 55% lightloss due to the polarization. Human eyes adapts pretty well but shutterglasses usually gives a very dark experience. Exceptions are lcd-displays which already are polarized but they're plagued with other issues (too slow to handle 3d properly).

2) This projector has no lens shift, but does have keystone correction. Reading your post, your telling me that there will not be a problem to align the two images?
No problem aligning but you'll get a slight resolutionloss: Lenseshift is a mechanical adjustment of the lense in the projector. This will enable full resolution when adjusting keystoning. As said i use digital keystone correction (the resolution regressively decreases to compensate for the keystoning) with my beamers and honestly i can say i would wish for lenseshift to have full native resolution. When running in native resolution of the projectors i get slight visible scalingartifacts because of the keystonecorrection. By jacking up resolution from 1024x768 (projectors native) to 1280x960 every scaling+keystone artifacts are completely gone. It of course means that the graphics needs to "struggle" with 1280x960 instead of 1024x768. It's usually no big issue.

3) Can you please direct me where I can buy a silver screen for this set up? One that doesn't show signs of crosstalk or ghosting, no hotspot etc. Basically a decent one. I really don't want to paint if I dont have to. Also filters will be needed that can withstand the heat, so can you please show me where I can get these linear filters?
For silverscreens (i have only personal experience with silverfabric and painted screens with very good result) i refer to this thread: [url="http://www.mtbs3d.com/phpBB/viewtopic.php?f=3&t=2719"]http://www.mtbs3d.com/phpBB/viewtopic.php?f=3&t=2719[/url]
Since you're planning to sit as close to the screen i recommend getting one with a gain between 1.5 and 2.0. I have a little hotspotting as is now (gain 2.4 and sitting 9 feets from the screen) but it's no big issue.
Plastic polarizers will do fine, at least in the beginning (polarization.com etc). You may need to have a distance of a few centimetres from the projectorlenses. I successfully tested my projector with plastic polarizers from polarization.com and they survived 50 hours of gaming before i switched to my spar-filters again. The plastic polarizers are still intact. The distance needed between the projectorlenses and the filters depends on how the focus of the beam behaves. At 7 centimeters i had a "shining area" of ~50x40 mm's (which is where the plastic filters survived 50+ hours with 2500 lumens).
For site selling glassespolarizers there are: [url="http://www.advisol.co.il/quickselectionguide.html"]http://www.advisol.co.il/quickselectionguide.html[/url], [url="http://www.awater3d.com/en/3d-stereo-polarizers/"]http://www.awater3d.com/en/3d-stereo-polarizers/[/url] plus more.
Extranote: Some filters works only for lcd-projectors to give very high transmissionrates (spar-filters for example). When attached to dlp-projector they actually works worse than standard linear filters. Feel free to ask more if you're confused.

4) I will be sitting 6-8 feet away from the screen. Realistically how big a screen can i get? 100inch?
I have 100" and sitting ~9 feets from it. It's perfect for games (i'd like one size bigger though) but almost too big for movies. I can move a bit backwards though.
Be sure that the projectors give such a big image. How much space do you have? Of the manual it seems like an Acer H7530D throwlength of 10-11 feets will give an image of 100".

Great thread for over all additional info: [url="http://www.mtbs3d.com/phpBB/viewtopic.php?f=26&t=509"]http://www.mtbs3d.com/phpBB/viewtopic.php?f=26&t=509[/url]
Link to a vid on how good selfpainted screens can be: [url="http://www.mtbs3d.com/phpBB/viewtopic.php?f=26&t=2719&start=41"]http://www.mtbs3d.com/phpBB/viewtopic.php?...19&start=41[/url]. The upper image is the silverfabric silverscreen and the lower the homesprayed.
This example is only sprayed unevenly but gives imo amazing results. Priming before painting will probably give the perfect image. The worst part with painting your own screen is actually finding the space to do it...

I wrote a lot here that seems complicated but generally a dual projection rig is very easy to setup and the successrate is very high.

Link to a vid on how good selfpainted screens can be: http://www.mtbs3d.com/phpBB/viewtopic.php?...19&start=41. The upper image is the silverfabric silverscreen and the lower the homesprayed.

This example is only sprayed unevenly but gives imo amazing results. Priming before painting will probably give the perfect image. The worst part with painting your own screen is actually finding the space to do it...



I wrote a lot here that seems complicated but generally a dual projection rig is very easy to setup and the successrate is very high.
