The 3D DLP projectors are one of the most affordable solutions to get a large screen with 3D support, whether it is for watching 3D movies at home or for playing games in stereo 3D with a better sense of immersion. There are a lots of models available on the market using various interfaces and having different resolutions and capabilities and all of these may cause a confusion and as a result you may end up with a 3D-capable projectors that does not work the way you wanted it. There are a few very important things that you should be aware of when considering buying a new 3D DLP projector or already have one, but you still haven’t used its 3D capabilities and you want to try them out. One of the most important advantages, besides the large projected screen of a 3D DLP projector is the fact that the technology does not suffer from issues with crosstalk, unlike 3D-capable monitors or 3D HDTVs. So let us see what is the most important information that you need to know.

When talking about a consumer level affordable 3D DLP projectors there are two main types of modes being used for providing support for stereo 3D, these are frame sequential input (can be over a VGA or HDMI interface) or HDMI 1.4 frame packaging. The interface and mode being used by a 3D DLP projector is very essential on what else will you need and how can you use the projector, so you must carefully choose the right interface based on what toy are going to be using the projector for and even depending on what other hardware you have in your PC. You should be well aware of the fact that there are still no affordable consumer level 3D DLP projectors capable of providing 1080p resolution in 3D mode with high-enough refresh rate for comfortable gaming. So regardless of the interface a 3D DLP projector uses and the native resolution it supports you can forget about being able to play games in stereo 3D mode at 1080p resolution for now, but you can still watch 3D movies at Full HD resolution if the projector is with 1080p native resolution. And this is just one of the examples of the limitations and features you should be well aware of when considering to use a 3D DLP projector, especially if you still haven’t purchased one. But there are a lot more specific things…


3D DLP Projector with frame sequential support:

– You can supply the frame sequential output over VGA or HDMI 1.3 interface.
– The projector is limited to 720p resolution in stereo 3D mode as maximum.
– In order to use the projector in stereo 3D mode it has to be in its native resolution (can be up to 720p).
– Besides being able to use stereo 3D mode at 60Hz per eye, you can also use 120Hz refresh rate in 2D mode.
– You can use any standard pair of DLP Link glasses with it, there is no need for any kind of emitter as the technology uses special kind of white light flashes embedded in the image being displayed.
– With DLP Link glasses you are good to watch 3D videos with the help of any software player capable of outputting 3D in frame sequential mode such as the Stereoscopic Player for example.
– With DLP Link glasses you are not able to directly play games in stereoscopic 3D mode or watch Blu-ray 3D movies without having to meet some additional hardware requirements and use extra software.
– You can use DLP Link glasses to play games in stereo 3D mode only if you have a compatible AMD-based graphics card supporting AMD’s HD3D technology (Radeon HD 5000 series and up) together with the TriDef 3D softare.
– You can use Nvidia’s 3D Vision active shutter glasses together with their specific IR emitter to play games in stereo 3D mode if you have a compatible Nvidia-based graphics card (GeForce 8×00 series and up), you can’t use DLP Link glasses with 3D Vision.
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– If you want to be able to play Blu-ray 3D movies then DLP Link glasses are not an option and if you have AMD-based graphics you are out of luck, all of the software players supporting Blu-ray 3D playback on PC such as PowerDVD have support only for 3D DLP projectors using Nvidia’s 3D Vision technology.


3D DLP Projector with HDMI 1.4 frame packaged support:

– You need to use the HDMI 1.4 interface on the projector
– The projector should be either 720p or 1080p native resolution, you will be limited to respectively 720p or be able to use both 720p and 1080p resolutions for stereo 3D, but wit the limitation of using 720p resolution at only 50/60 Hz 3D mode or 1080p at 24Hz 3D mode.
– Even if the projector is with 1080p native resolution, the refresh rate supported at it in 3D mode is limited to 24Hz which is good on for 3D movies, for games you still have to resort back to 720p resolution where you can use either 50Hz or 60Hz in 3D mode.
– With HDMI 1.4 3D DLP projectors you are not able to use 120Hz refresh rate in 2D mode as you can with the frame sequential models.
– These projectors still rely mostly on the standard DLP Link glasses, though there are some models available offering RF glasses as well, but due to the specifics of the HDMI 1.4 3D support the type of glasses used is of not much concern as long as the projector is compatible with them.
– The 3D DLP Projector with HDMI 1.4 frame packaged support do not have support for frame sequential input.
– You cannot use the Nvidia 3D Vision active shutter glasses with these projectors, you either need a generic DLP Link glasses or any other specific model designed for the particular projector (RF glasses for example).
– You can play any kind of 3D videos and movies, including Blu-ray 3D movies as long as you have a software 3D video player and a video card capable of supporting HDMI 1.4 frame packaged output.
– All software players with support for Blu-ray 3D movie playback such as PowerDVD will be able to play 3D movies if you have at least an a second generation Intel Core processor (Sandy Bridge) in order to have support for Intel’s InTRU 3D technology, and this means Intel Core i3, Core i5 or Core i7 CPU, Pentium processors won’t do as they don’t feature InTRU 3D support. For owners of AMD-based video cards the minimum is Radeon HD 5000 series (all AMD HD3D capable video cards should work, though some may not support GPU acceleration for Blu-ray 3D) and for owners of Nvidia-based GPUs the minimum is GeForce GTX 260 or GeForce GT 320 according to Nvidia (some of supported GPUs might not have GPU acceleration).
– When talking about gaming in stereo 3D mode, using Intel’s integrated GPUs is out of the question as they are simply not powerful enough and regarding the AMD and Nvidia-based GPUs the limitation is the same as with Blu-ray 3D movie playback above – you need ca graphics card supporting either Nvidia’s 3DTV Play or AMD’s HD3D technology that can supply HDMI 1.4 frame packaged output.
– Owners of compatible AMD-based hardware with AMD HD3D technology supported need to use the TriDef 3D software (the same as frame sequential users would), owners of Nvidia-based graphics cards need to use Nvidia’s 3DTV Play software (instead of the 3D Vision for owners of frame sequential capable projectors).
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– Projectors relying on HDMI 1.4 frame packaged input do tech do have more input lag than models using frame sequential input for stereo 3D and while this isn’t an issue for watching 3D video on them it can be a bit of a problem for some (not all) gamers playing in stereo 3D mode.

You should note that the newer 3D DLP projectors using HDMI 1.4 for 3D support are not suitable for some owners of older Nvidia-based hardware that would work with frame sequential models for example such as the GeForce 8800 which although old is still quite popular and widely used product and quite capable for gaming in the not so demanding 720p resolution even in stereo 3D mode. And with regards to the increased input lag required for the processing of the frame packaged 3D input and the lack of support for 120Hz 2D mode the frame sequential models might still be more attractive for people that are going to be using them mostly for gaming. On the other hand 3D DLP projectors using frame sequential mode are more restrictive and hard to setup for users that are going to be using them mostly for watching movies in 3D whereas the HDMI 1.4 interface makes it much easier. For gaming in stereo 3D mode on a 3D DLP projector there is still not way to get 1080p resolution, so the far that some 3D DLP projectors with HDMI 1.4 interface are with native resolution of 1080p does not help at all as you’d still have to resort to 720p resolution when playing games in stereo 3D mode anyway due to the limited refresh rate at the higher resolution.

DDD is offering a trial version of their TriDef 3D software and Nvidia also does offer you to download a 14-day trial version of the 3DTV Play software from their website, so you can get these to try things out and if everything works then you can buy a license for the software. There is no trial version of the 3D Vision software as it is a part of the Nvidia graphics driver now and it includes only free anaglyph 3D mode, the 3D Vision functionality is tied to hardware requirements as well anyway. If you already have the IR emitter of a 3D Vision kit connected to a PC you get free 3DTV Play functionality, so there is no need to buy a separate license for that.

As you can see 3D DLP projector support overlaps quite a bit in the frame sequential models, though there are some models and brands covered by official support only by either AMD or Nvidia. Unlike Nvidia however AMD is much more open to support for projectors supporting HDMI 1.4 frame packaging as there is no official list of devices on their website. Now, if you already own a 3D-capable DLP projector that is not on the list don’t worry, there is still some chance that you might be able to make it work via a workaround solution, however you should be warned that things like IR emitter emulators, or EDID override drivers may or may not work in your case and even if they tend to work you might face different issues or problems and you never know if they won’t stop working soon. So resort to trying the different workarounds (some of which are also being discussed on this website) as a last resort if you already own a device that is not on the officially compatible list, if you are making the decision on what to buy now, better choose a compatible model fitting your needs and requirements, as this can save you a lot of trouble later on.

Optoma HD33 is a New Very Affordable Full HD 3D DLP Projector

August 21st, 2011 · 14 Comments · General 3D News


If you were waiting for a more affordable 3D-capable DLP projector that can provide you with native 1080p resolution, than Optoma might have just the right thing for you, their new Full HD 3D projector with model number HD33. Most certainly Optoma HD33 is not the first Full HD 3D projector out there, however it is the most affordable one that combines the high resolution with 3D support and that is actually the most interesting thing. The end user price of the Optoma HD33 should be about $1,499 USD, and that is something very attractive indeed considering that most other more-affordable alternatives with similar features are at least twice or even three times more expensive.

Now, before getting too excited about being able to play games in Full HD resolution in stereo 3D mode on your PC, I should make it clear that this projector (like most other such) relies on HDMI 1.4a interface, something that is both good new for some users and not so good for others. Since the Optoma HD33 projector does not feature a Dual-Link DVI interface you can forget about being able to use it with 3D Vision for gaming in stereo 3D mode at 1080p resolution. The projector might however get added as a supported product in the 3DTV Play software, however it will not be compatible with the 3D Vision active shutter glasses. You’ll need to use a pair of DLP Link active shutter glasses or Optoma’s new BG-3DRFGLASSES 3D-RF glasses (actually looking exactly like Monster Vision Max 3D made by BitCauldron). Apparently the projector has been developed for entertainment purposes, Blu-ray 3D movie watching or for console gamers willing to play in stereo 3D mode for example and not with PC gamers in mind.



The HD33 should support all the HDMI 1.4a mandatory 3D formats, including of course the most commonly used Side-by-Side and Top & Bottom formats, and to further enhance 3D compatibility, Side-by-Side and Top & Bottom formats can be manually enabled to allow other non-HDMI 1.4a compatible devices, such as older set top boxes, Xbox 360, or PCs to display 3D via the VGA or HDMI ports. The HD33 projector offers two HDMI 1.4a ports, one VGA port, as well as connections for component video, composite video, RS-232, a +12V trigger, and a VESA 3D Port. The maximum brightness offered by Optoma HD33 is 1800 ANSI lumens and the contrast ratio is 4000:1, the projection lamp is rated to last up to 4000 hours in standard mode or 3000 hours in bright mode.

The Optoma HD33 1080p 3D-capable DLP projector is now available at Amazon…

VIP 3D-Gamer is an HDMI 1.4 to 3D DLP Projectors Video Converter

January 19th, 2011 · 5 Comments · Other S3D Tech


It seems that the Optoma 3D-XL adapter may have a cheaper alternative that can be available on the market earlier, but with a bit more limited functionality. There is a new company called Video Innovation Products (VIP) that should soon start shipping their VIP 3D-Gamer conversion adapter that can have HDMI 1.4(a) stereo 3D input and output frame sequential stereo 3D that can be understood by 3D DLP projector. This means that you should be able to connect your PlayStation 3 console via this adapter to a 3D DLP projector and play games in stereo 3D mode. The adapter is just converting between the formats, so for the projector you would still be using a pair of traditional DLP Link glasses. The adapter might also be able to turn your 3D DLP projector into a compatible with 3DTV Play for gaming as well, although that needs to be verified if it will work when the converter becomes available in the beginning of February. The price announced for the VIP 3D-Gamer video conversion adapter is $199 USD and you can buy it also bundled with a pair of DLP Link glasses for $259 USD (the glasses do look very much like 3D Vision) or a separate pair of glasses for $79 USD each.



The VIP 3D-Gamer product is designed only for gamers and supports only the 720p 50Hz/60Hz 3D modes as input over HDMI 1.4(a), it is however not compatible with the 1080p 24Hz 3D resolution used for movies. This simply means that you will not be able to use this adapter together with a standalone Blu-ray 3D player to watch on your 3D DLP projector, but the company apparently has another more flexible solution for 3D movie lovers. They should also soon start offering a 3D-Displayer and 3D-Theater products that will offer more features and support both the gaming and movie playing in stereo 3D coming from all kinds of 3D-ready devices using HDMI 1.4(a) and being played back on a big screen supplied by a 3D DLP projector, as well as some other ore advanced features. But these products will probably be more expensive and will probably compete with the Optoma 3D-XL adapter both in terms of features and price and they will most likely be released at the same time too.

But back to the coming very soon VIP 3D-gamer product. Aside from only supporting 720p 50/60Hz 3D input you will also need to have a 3D DLP projector that has and HDMI input and that is with native resolution of 720p (able to output 720p in stereo 3D mode) like for example the Acer H5360 or Optoma HD66. The adapter itself is apparently powered over a mini-USB port, so you will probably need to have a device to plug it in or an USB power adapter, but the USB port might as well be usable for lets say firmware upgrades. You should also have in mind that that Side by Side or Above/Below inputs are not being supported as of this moment as only the HDMI 1.4(a) frame packaging format can be translated into frame sequential stereo 3D. And as will all image processing devices you should be aware of the fact that adding the VIP 3D-Gamer adapter may introduce slight additional lag on top of any possible lag that the projector may already have. Now let us wait a bit more and see what the first people that get the device will report about it…
