We've just spent a few weeks looking at four of the most exciting digital projectors to hit the market in a long time. They all feature high resolution HD 1920x1080 light engines, and they all bring 1080p to the consumer at prices previously unheard of. Perhaps the most important observation we can make about them is this: no matter which one you buy, you will be thoroughly delighted with the results. Our task has been to evaluate them closely side by side, so that we can detect the differences between them. Many of those differences are quite subtle, and some are more apparent. In most cases, unless you have them sitting side by side, you'd never recognize the particular advantages and limitations to each of them since on their own -- they all look great.
Another important conclusion we came to is this: there is no single projector that could possibly "win" this shootout. Each projector does something better than the others. It is up to you to determine which of the features and image quality characteristics are most important to you, and which you can accept a little compromise on. These are matters of personal taste, and what is important to us may not be to you.
Here are how these four great projectors rank on various performance and feature characteristics.

<B>Sharpness/Clarity of High Definition 1080p Images
1. Mitsubishi​

2. Optoma​

3. Panasonic​

4. Sony</B>​

The Mitsubishi delivers the sharpest image of the four when the source is 1080p from HD DVD or Blu-ray. The Optoma ranks a very close second and has quite a sharp image as well. The Panasonic and Sony manifest a more apparent softness, with the Sony being the softer of the two.​

<B>Sharpness/Clarity of Standard Definition DVD Image
1. Panasonic​

2. Optoma, Mitsubishi, Sony</B>​

The Panasonic wins hands down in this category, delivering a DVD image that stands apart from the rest. It has less digital noise and ringing than the others. Meanwhile, the other three are essentially comparable.​

<B>Deinterlacing of Standard Definition sources
1. Mitsubishi​

2. Panasonic, Optoma​

3. Sony</B>​

There is some real nitpicking going on here. The Mitsubishi is the best of the group, and the Panasonic and Optoma are tied for a very close second. Sony comes in third, but even the Sony is extremely good.​

Lumen Output
These readings describe video optimized ANSI lumens in high lamp mode with zoom in wide angle position. Subtract zoom lens factor if lens is in maximum telephoto position (Note: The reason for the radical difference in zoom lens factors is that lumen variances on a given projector generally correlate to the zoom range of the lens, which differs greatly among these models): 1. Optoma: 655 lumens, -6% at max telephoto​

2. Mitsubishi: 532 lumens, -24% at max telephoto​

3. Panasonic: 500 lumens, -45% at max telephoto​

4. Sony: 404 lumens, -25% at max telephoto​


<B>Contrast
1. Sony​

2. Optoma​

3. Panasonic​

4. Mitsubishi</B>​

The Sony can achieve the highest contrast of the four at the expense of lumen output. The Optoma offers an excellent combination of high contrast and high lumen output. The Panasonic ranks third, and the Mitsubishi has the least contrast of the four. However, these are all high contrast projectors, and their performance is relative to one another. With HD sources, even the Mitsubishi shows excellent dynamic range and sparkle.​

<B>Black level:
1. Sony​

2. Optoma/Panasonic​

3. Mitsubishi</B>​

Sony takes first place honors with the deepest, richest black level of the four. Black levels will depend upon calibration, but in general the Optoma and the Panasonic are equal for most anticipated settings that people will opt for. Black level is still quite satisfying on the Mitsubishi, but the picture is a bit brighter and blacks are less deep in optimum calibrations.​

<B>Zoom lens:
1. Panasonic:</B> 2.0:1 powered​

2. Sony: 1.72:1 powered​

3. Mitsubishi: 1.60:1 powered​

4. Optoma: 1.20:1 manual​
<B>Lens shift:
1. Panasonic:</B> 3 picture heights, 45% horizontal, manual​

2. Mitsubishi: 2.5 picture heights, 10% horizontal, powered​

3. Sony: 2.0 picture heights, no horizontal, powered​

4. Optoma: none​
Connectivity:
1. Optoma 3 HDMI, 4 component, 1 VGA​

2. Panasonic: 2 HDMI, 2 component, 1 VGA​

3. Sony 2 HDMI, 1 component, 1 VGA​

3. Mitsubishi 1 HDMI, 1 DVI, 1 component, 1 VGA​
<B>Audible fan noise:
1. Mitsubishi​

3. Panasonic, Sony​

4. Optoma</B> The Mitsubishi is the quietest of the four, being almost silent. The Panasonic and Sony are very low in fan noise to where it is not a concern. The Optoma is the only one of the four that has enough fan noise to be concerned about. In high lamp mode, it could be a distraction unless steps were taken to isolate and baffle the noise. In low lamp mode it is a bit louder than the Panasonic and Sony, but it would not be a distraction if ceiling mounted behind the seating area.​

<B>Current estimated street prices as of this writing:
1. Panasonic:</B> $4,000​

2. Mitsubishi: $4,500​

3. Sony: $4,800​

4. Optoma: $6,800​
<B>Warranty:
1. Optoma:</B> 3 years​

2. Mitsubishi, Sony: 2 years​

3. Panasonic: 1 year​

Extended warranties are often optional at extra cost. Check with dealers for price and availability.​




Summaries and Conclusions



Mitsubishi HC5000

Advantages:
  • Maximum image sharpness and detail with 1080p sources
  • Relatively bright in video optimized mode
  • Excellent versatility for installation
  • Virtually silent fan noise
  • Aggressively priced at $4,495, a great value
Limitations:
  • Contrast and black level are good, but not quite as good as the competition
  • Digital noise is average with standard definition sources
For us, the overriding advantage of the Mitsubishi HC5000 is extreme image sharpness with HD DVD and Blu-ray sources. The reason we want to spend premium dollars for a 1080p projector is to get that pristine clarity and fine detail. The Optoma comes very close, but the Panasonic and Sony fall somewhat short of the HC5000 in their ability to resolve fine detail in HD. While the HC5000 does not match the black level and contrast of the competing units, its superior razor sharp image gives it the appearance of having more three dimensionality in HD. It is clearly our choice among the four for viewing high resolution materials from HD DVD and Blu-ray.



Optoma HD81
Advantages:
  • Brightest projector in the group—great for larger screen theaters
  • Excellent sharpness and detail with HD sources
  • Great black level and contrast
  • Extensive connectivity
  • No air filter to maintain—the only one in the group that is filter-free
  • Three year warranty – the longest in the group
Limitations:
  • Lensing places restrictions on installation options
  • Added cost and effort to ceiling mount
  • Fan noise is above average
  • Most expensive model of the four
The Optoma HD81 is the ideal solution for a larger scale home theater. It comes very close to matching the Mitsubishi HC5000 in sharpness of an HD image, but it has superior black level and contrast. Even in low power mode it pumps out about 500 ANSI lumens, so it is capable of lighting up a 150" diagonal screen or larger in a way that none of the competition can. In larger viewing rooms the fan noise becomes much less relevant. It is more expensive than the others, but if you are going for a large scale theater with an image size of 150" or more, you've already putting more money into the room and screen, and going for a larger budget solution. For this type of theater, ceiling mounting is preferred, and the cost and effort to ceiling mount are non-issues. If we were building a big theater room, the Optoma HD81 is the first 1080p projector we'd be considering.



Panasonic PT-AE1000U
Advantages:
  • Spectacular picture quality with DVD
  • Reasonably bright if installed properly
  • Superb black level and contrast
  • Excellent versatility with zoom and lens shift
  • Low fan noise
  • Low price
Limitations:
  • Subtle softness with HD DVD and Blu-ray sources
  • Short one-year warranty—extensions may offset price advantage
  • Some calibrations and lens settings seriously curtail brightness
We were overwhelmed by the superior image quality that the AE1000 produces with DVD. If there were no softness in the HD image it would be our favorite projector of the group. However, if you are planning to view a lot of DVD and broadcast HDTV, and don't mind a slight touch of softness in pictures from HD DVD and Blu-ray, then the softness we've mentioned is no big deal, and the AE1000 would be the best solution overall for you.



Sony VPL-VW50
Advantages:
  • Deep black level and very high contrast
  • Excellent color saturation
  • Long zoom range for ease of installation
  • Beautiful casework design
  • Low fan noise
Limitations:
  • Least bright of the four units
  • HD & SD images are the softest of the four
  • Average digital noise in standard definition
If the Sony VPL-VW50 is the only 1080p projector you've seen, then you will love its bold, rich picture with its very deep blacks and great color saturation. On its own it is a pleasure to watch and we certainly understand the enthusiastic accolades it is receiving from users.
One of the anticipated hot features of the reflective SXRD technology is the lack of pixelation. In this shootout, only the Panasonic AE1000 had zero pixel structure when viewed up close, while the other three models each had some degree of visible pixel structure. Of those, the Sony had the softest pixel grid. The Optoma HD81 (DLP) and Mitsubishi HC5000 (LCD w/ Microlens) had pixel grids that were more distinct, with the Mitsubishi being just a bit more distinct than the Optoma. But in 1080p resolution, none of the technologies are producing any pixelation that is visible from normal viewing distances, so it is not as much of a competitive issue as it once was. It is noteworthy that the two projectors with the softest images were also those with the least well defined pixel structure. Once the Sony was set up against the competition, we found its softness to be distracting to the point that it outweighed its black level and saturation advantages. The Mitsubishi and Optoma both produce much sharper images in HD, and the Panasonic delivers a much superior image in SD.
