The design of the W6000 chassis is definitely a 'love it or hate it', 'Marmite' statement. Its all plastic body is black in colour with a large silver BenQ logo on the rear top plate. The lens is positioned in a central mount on the front face plate and is silver plastic, looking rather cheap, in my opinion. This is an all manual implementation of lens focus and zoom, with a black joystick to the right hand side for lens shift adjustments. Should you lose the remote control, there are access keys to the top of the unit, which I was forced to use for the first few days of testing due to there being no remote control in the sample box. The keys on the unit are easy to use and responsive. Finally there is an air intake to the right hand side of the chassis, and to the front left is the exhaust port. Overall, the design of the W6000 is imposing and industrial which some will love and others will want to hide away in a dark projection room.
Moving to the rear of the chassis and we find a plethora of connections available. Here you will find two HDMI 1.3 slots, one component, one PC RGB connector along with legacy composite and S-video slots. For automated systems you have one 12v trigger and an RS232C control port. Also present is a mini USB connector which is used for servicing and is not for consumer use. Finally the power connector rounds up the back panel. For a mid priced projector, the connections available will be enough for the most demanding of installations, and the inclusion of a 12v trigger at this price point is welcomed.
Looking at the optical light path next, and this DLP projector has a six-segment colour wheel which also takes advantage of Texas Instruments BrilliantColour technology, along with control over the 280w UHP lamp from Philips Vidi lamp technology. The Philips technology is designed to boost the Red and Blue light spectrum to offer a brighter and more colour consistent image. Usually, with UHP lamps, the red energy is lower than that of Green and Blue wavelengths, which can mean that when calibrating, the light output is reduced as you dial down the Blue and Green elements to meet up with Red wavelengths. We will test this and measure the spectrum later in the review.
Some of the more advanced users will have picked up on the fact that the W6000 uses a 280W UHP lamp. This is quite a powerful and rare thing to find is such a budget model, the usual lamp ratings for home cinema projectors are around a maximum of 200w. The lamp life is quoted at 3,000 hours in eco mode and 2,000 hours in normal settings. The lens system used in the W6000 is not specified but close inspection reveals that it is a high enough quality of glass at this price point and it certainly produces a sharp and easy to focus image, with a throw ratio of around 1.5:1, we managed to produce a 96 inch 16:9 image easily from around 12ft back. The unit also has a dedicated picture stretch mode for use with an external anamorphic lens for a constant image height set up.
Picture processing on the W6000 is provided by a Hollywood Quality Video (HQV) processor for scaling and de-interlacing of all the common source resolutions. This is also complemented with a 10 bit colour processor which helps assist 8 bit images to produce finer gradation of colours with less noticeable banding. We will fully assess the video performance later in the review.
Measured Results Out of the Box
As you can see from the resulting scan the results are fairly good with a dip in the green wavelength being the only real issue. This will come back again when we measure the actual gamut on offer. Blue brightness and wavelength results, along with a stronger than normal Red wavelength, point to the Philips Vidi technology helping with these areas. So moving on to measuring the best picture preset (cinema) out of the box which has had just a basic set up of the front controls produces the following results.
Looking at the greyscale results first (RGB Level tracking, RGB Color Balance and the delta E boxes) we can see that the cinema preset with colour temperature warm produces the closest possible results to the standards. What we are looking at is the mixture of red, green and blue colours which if mixed equally at a given point, they make up the colour white. The greyscale is the colour white with luminance (brightness) removed in 10% steps from 100% to 0%. This should provide a table where the mixture of the colours are correct and there is no colour shift in the greyscale points.
As we can see with the results highlighted above, blue is quite high in the mix, with green and red around 5% under in the mix. This means that the greyscale has a very blue look and colour shift, which produces a bright image on screen, but one which is going to have a blue cast to it. Ideally the tracking lines should merge and delta E errors should be under 2 for a perfect greyscale performance. With these results the brightness factor has been pushed by the manufacturer over an accurate greyscale. We also check the gamma performance at this stage and can see that across the range of the greyscale it is mirroring the greyscale dominance of blue being too bright and we don’t quite have an accurate gamma curve to our desired 2.2 point.
Moving to the colour gamut and we see that the projector is not quite capable of producing the Rec.709 standard we need for accurate colours with Pal and HD material. Looking at the CIE chart you can see the solid lined triangle which represents the colour gamut of Rec.709 and where the colours should land within that. Plus we can see what the luminance (brightness) of these colours should also be. The dotted line and black dots represent the native colour gamut of the projector and as we can see it is not capable of reaching the desired points, especially on green. This also points back to our spectral scan where green energy was cut.
The results here show that Red is oversaturated and also has hue errors. Luminance for Red is also a little higher than we would want. This points to red on screen being over saturated and brighter than we want. Blue is also pushed for hue errors and although saturation appears to have fewer errors, the luminance of blue is high. Again these errors will be seen on screen. The major issue with our gamut is the green colour point which cannot match the desired co-ordinates and there is nothing we can do to fix this; as you cannot add in what is not there natively. With both these results we can see that there will be a blue cast to the image overall, with primary colours of red and blue oversaturated and the wrong hue and green lacking. So, what can we fix within the image given we have full ISFccc controls?
Looking at the greyscale first you can see that we have now fixed the mix of red, green and blue towards the correct amounts and that our errors (Delta E) are now under 1.2 across the board. This means that what small errors are there, we will not be able to see with the eye. Our Gamma performance is also now well balanced and hits the 2.2 points across the majority of the scale. The slight dips are caused by the brightness and contrast settings we have decided on. This means that the images on screen should now be without any colour shifting or casts and produce an image that now has some added detail in the white and black areas.
Moving to the colour gamut and we were able to correct the red oversaturation and hue errors as well as fix the luminance of the colour points to produce smaller errors that will be visible. This is more important than getting just the colour saturation and hue bang on. The colour performance is now more balanced and although there are things we just cannot fix, like a blue oversaturation and the lacking green point, on screen performance should be improved over the out of the box results. However, even though the projector has full ISFccc controls we cannot get the W6000 performance as accurate as we would like, which is a shame.
The other point that is the most striking with the W6000 is the brightness of the image, even when calibrated. This projector would certainly suit users who wanted to go for large screen sizes over 110” or to use the projector in a less than perfect light controlled room (with appropriate screen selection for the environment). While this brightness on offer is a positive in most respects, the resulting black level is not as ideal. Whilst the image is bright and when calibrated it can have a good amount of depth in bright scenes, the actual black level and shadow detail available is not comparable with the class leaders in this price range. Using the dynamic iris doesn’t really improve matters either as it is not the fastest we have seen, and it robs the image of a consistent luminance level. In mixed content scenes where we have blacks against brighter objects the W6000 lacks the kind of image depth across the range that we are used to seeing with units like the PT-AE4000. However, the competition would also struggle to match the W6000 for its brightness and depth with daylight scenes or animation content. So, we get a mixed performance from the projector in both out of the box and calibrated settings.
Out of the box, care must be taken in image set up as the presets on offer are not the best we have seen, with a strong blue cast to images and colours that can look too oversaturated. Indeed one surprise I found was the amount of image noise visible in most presets using out of the box settings. This is somewhat curtailed when correctly calibrated to the standards but even then, colour performance is best described as abstract! Gradation and banding are not issues thanks to the projector's 10 bit processing, but no matter how hard I tried, colour accuracy was just a tad over the top, especially with some skin tones. Overall, the W6000 offered just too many negatives within its on screen images to satisfy those looking for image accuracy and strong black levels.
- Excellent brightness levels for large screens
- ISFccc control added as standardEasy to use remote control and features
- Excellent greyscale when calibrated correctly
- Vivid colours and image brightness for those looking at a gaming projector
- Good quality scaling and de-interlacing
- Good quality 10 bit colour processing eliminates banding
- Colour inaccuracies on screen and inaccurate skin tones out of the box
- Black levels are lacking against the competition
- Lack of dynamic range in the lower reaches, with a lack of shadow detail
- Noisy fan and iris
- Not the most cinematic or accurate of images even after calibration
BenQ W6000 Full HD DLP Projector Review
The W6000 is also not the quietest projector out there either with a running noise floor that is at least 10db louder than most projectors we have tested recently. Plus the colour wheel and iris are also not quiet in their operation with an occasional metallic grinding noise heard now and again.
Overall, I think that film and TV fans looking for the best cinematic and accurate images available can look elsewhere, such as the Panasonic or Epson ranges at this price point. I didn't feel it was necessary to add any comparison to our reference HD950 as the price difference alone makes that a moot point. So, it’s a very mixed bag in the end for the BenQ. That’s not to say that this projector doesn’t have any merits in image quality and of course brightness. Rather it struggles to offer an image that has the type of subtle colour tones and black depth that the very best in it's class manage to produce.
