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 3D DLP Projector Adapter 3D-XL is Coming in January

October 31st, 2010 · 23 Comments · General 3D News


It seems that Optoma is almost ready to to release the much hyped 3D DLP Projector Adapter 3D-XL that will add support for HDMI 1.4a input for stereo 3D content to 14 of the company’s 3D-capable DLP projectors as well as 3D DLP projectors from other brands. Optoma has officially announced more details about the adapter as well that the 3D-XL projector adapter will be available in January 2011 and although the official price is not yet announced, Amazon has already listed the 3D-XL adapter for pre-order with a price of $499 USD. It certainly won’t come cheap, but in the price there will be one pair of Optoma’s BG-ZD101 3D active shutter glasses sold for $99 USD and based on the DLP Link technology. And if you compare the price of a 3D DLP projector plus the 3D-XL adapter to a 3D HDTV or some of the high-end 3D-capable projectors that were already announced to feature HDMI 1.4(a) S3D support, you might still be saving quite a lot of money.

But why would you need to have HDMI 1.4a compatibility for stereoscopic 3D support, when your 3D DLP projector already can receive 3D data and display it? Well, actually you might not, unless you want to be able to lets say connect your PlayStation 3 console to the projector and play stereo 3D games on it, or connect a 3D-capable set-top-box, or a standalone Blu-ray 3D player. Of course that also includes other 3D-capable devices that support 3D video output over HDMI like the Fujifilm Real 3D W3 camera, Sony’s 3D Sweep Panorama-capable digital cameras and probably a lot other that are yet to come. If you need it or not is something for you to decide, but if you already have a 3D-capable DLP projector this adapter can prove to be a good way to ensure big-screen 3D viewing…



On the front side of the adapter there are just three buttons, one for turning on and off the adapter, one for switching between 2D and 3D mode and one for using one of the two available input ports. By activating the 2D mode you are practically doing a pass through of the signal to the projector and in this mode you can send 1080p data, but in 3D mode you are limited to 720p only. And considering the fact that there are still no 3D DLP projectors with native resolution of over 1080p this is actually not such a big problem, and when the first 1080p 3D-capable ones start hitting the market probably early next year they will most likely also come with built-in HDMI 1.4a support anyway.



You should be aware of the fact that your 3D DLP projector should have an HDMI input in order to work with this adapter as the output is only in the form of an HDMI. You can see that there are two independent inputs, meaning that you can connect two different 3D devices and switch between them without having to change cables. The adapter is designed to be used with DLP Link glasses, so there is no need for an external IR emitter, although the adapter has a 3-PIN mini DIN (VESA Sync) output available.

It seems that Acer won’t be the only company offering an affordable 720p projector with 3D support, as Optoma has just announced their own 720p 3D Ready home theater projector. Optoma HD66 offers a wide aspect 16:9 ratio and native resolution of 1280×720 pixels, the maximum brightness is 2500 ANSI lumens and the maximum contrast ratio is 4000:1. The new projector weights just about 2,3 kilograms (5 pounds). The projector can be used for either front or rear projection, it can be ceiling or tabletop mounted and will project images from 23″ to 300″ diagonal. There is a built-in two-watt speaker for audio playback, but you’d probably prefer to use something with better sound quality and power when playing games or watching movies.

The HD66 is using Texas Instruments’ 0.65 DMD DLP chipset and has HDMI, DSUB15 (Analogue VGA), S-Video and Composite Video inputs, but as with the Acer there is no clarification what input you can use with 120Hz for Stereoscopic 3D mode. Optoma HD66 can project in stereoscopic 3D in 720p HD (1280×720), XGA (1024×768) and SVGA (800×600) resolution according to the manufacturer and of course requires you to use active shutter glasses, but is not yet officially supported by 3D Vision! Optoma HD66 has an a recommended end user price of $699. Now lets see who will be the first one with a Full HD 1080p 3D-capable projector… ;)
