The HD66 is a 720p projector, with a native resolution of 1280 by 720 pixels. However, it can accept and scale signals at other resolutions, ranging from VGA and standard definition right up to 1080p. To test how well it does with these, we use a number of test screens to examine how well it scales these images.
1080i & 1080pThe HD66 can't show every pixel of a 1080 video signal because it has a lower resolution. So, it downscales the image to the same size as a 720p image, reducing the 1920 by 1080 pixels of the image to fit the 1200 by 760 pixels of the display. This downscaling gives images a somewhat soft appearance and looses some details. We also did not see any difference between feeding the projector a 1080i (with 30 interlaced frames a second) image or a 1080p one, which contains 60 full frames a second.

The HD66 is a 720p projector, which means that it has a resolution of 1200 by 800 pixels. This means that it can display video signals at up to 720p resolution at their full resolution, but anything higher than that is scaled down to fit the resolution the projector works at. We found that it did an effective job of this, though: signals like the 1080i and 1080p ones produced by devices such as Blu-ray players and HD cable boxes looked sharp and clear.

The 3D-XL couldn't be much easier to set up. You plug in the power adapter, connect your sources (up to two) to the unit via HDMI cables, and then plug the 3D-XL's HDMI output into your 3D-compatible DLP projector. We used Optoma's HD-66, a 720p 3D-capable projector which sells for under $700. You then flip the toggle switch on the back of the 3D-XL to its 720p output mode. In this mode, the 3D-XL takes any compatible incoming 3D signal and scales/processes that 3D signal to a 720p/120 Hz 3D output which is compatible with most (if not all) 3D-capable DLP front projectors. As a 3D source device, we used Panasonic's SC-BTT350 Blu-ray 3D Home Theater System set to its 1080p 3D output. We also did some 3D testing from YouTube using Side by Side 3D content.
Watching Avatar on Blu-ray 3D Disc plus a number of additional Blu-ray 3D titles, including Step Up 3D, Cloudy with a Chance of Meatballs, Grand Canyon: A River at Risk, Tron:Legacy and Coraline, we can say that the 3D-XL does exactly what it is advertised to do. It takes the output of a 3D source component (namely a Blu-ray 3D player) and creates a 3D signal that is fully compatible with the current crop of 3D-capable DLP projectors. Sure, the resolution is scaled from 1080p down to 720p so there isn't quite as much detail as you would see from a full HD 1080p 3D system, but the quality is still quite acceptable on a 92-inch screen from less than 10 feet away. And the total price of our review system -- projector, screen, Blu-ray 3D home theater system, 3D-XL box, 3D glasses and cables -- comes in at under $1500. Try that with a flat panel 3D TV. You can read more about the complete system in our article, "Big Screen 3D Home Theater Under $1500."
The 3D-XL has an alternate "1080p" output mode which can be used with a dual projection system, thereby enabling the use of passive 3D glasses and full HD 1080p resolution in 3D mode. In this implementation, you'd actually need two 3D-XL boxes, with one set to 1080p/Left and the other set to 1080p/Right and you'd feed these outputs to two separate projectors.
For those who are excited by the possibility of a 3D home theater with a nice big screen, the 3D-XL, combined with a 3D-capable DLP projector from Optoma or other manufacturers represents a compelling, affordable alternative to expensive full HD 1080p projection systems or puny flat panel 3D TVs. Although a remote control would have come in handy, particularly when viewing SBS 3D content on YouTube, the 3D-XL does exactly what it is advertised to do and does it well. It enables big screen high definition 3D home theater at a price that won't break the bank.
