Design and connections
Given that the W1000 is built to a price point we can perhaps also forgive the fact that everything bar the lens is made from moulded plastic and that the main controls for lens zoom and focus are manual affairs. Plus, don’t expect any kind of lens shift capabilities either, as the W1000 follows other budget DLP models in offering a fixed image offset. This means that placement in relation to the screen (either from a coffee table or ceiling mount) is vital to avoid unwanted use of the keystone adjustments. Using any kind of keystone adjustment with a projector is not recommended as it will add in artefacts to the image projected, so take your time by following the suggested positioning points in the manual, to get the projector installed correctly. However, if you are planning on using the projector for the occasional film and TV football game and putting it away afterwards, you will be able to do that easily, but again, unless you take some care in placement you will end up with some image issues. A possible advantage here is the short throw lens which means that even in small rooms; you should be able to get a decent size of image from your mounting position.
Moving around the back of the chassis we find the usual array of connections for your sources. We have two HDMI slots along with one set of component RCA, s-video, composite and a PC RGB connector. Also included are an RS232C port along with 3.5mm Audio and RCA audio input/output connections. Some of you will also have noticed a USB port on the back panel but this is purely for service use and does not allow any USB playback devices to be connected to the projector. What is odd, and perhaps harks back to this projectors business roots, is the inclusion of a 3W speaker on the back of the chassis. Of course as a home cinema projector this is completely redundant (as are the audio input connections) but I guess if you wanted to use it for both applications, the W1000 could easily fulfil your business presentations as well as the home movie watching role.
Out of the Box Measurements
First lets start with the Greyscale and I suppose if I am honest I can admit to giving a sigh of relief when the results popped up on screen. It could have been a disaster if the white balance was not tracking anywhere near the D65 white point we want for the playback standards. That’s because if it was off in any serious way there are no manual controls provided by the W1000 to correct the values back to where they should be. However, as you can see from the RGB Balance and tracking windows the W1000 has an excellent result with greyscale tracking close to what we need and with detaE errors under 2 for the most part.
This is a very welcome result and will give us an accurate level of white on screen with errors almost invisible to the human eye. I must however point out that the results obtained here may vary from other W1000 projectors by some degree depending on lamp life or the quality of BenQ factory calibration of the white balance points. We have no data that would suggest that there would be a massive difference from unit to unit, but it is worth pointing out anyway. Moving on to the colour gamut and this is where things are a little more disappointing, but certainly not a disaster for such a cheap projector. First of all let's look at what a native gamut is.
The native colour gamut of a projector or TV is what that display is capable of resolving in terms of colours. If you look at the CIE chart the solid lines are the Rec709 HDTV colour standard points. The broken lines with black dots are the colour points that the W1000 is natively capable of displaying. In the case of the W1000 this will have a lot to do with the colour wheel and the lamp used as to what we see on screen and in the chart. If the points are inside the solid triangle and towards the white point square, this indicates that the colour point is under saturated when compared to the desired colour box.
Also if the black points are to the side of the colour box in a semi-circular fashion this points to the hue of the colour also being off target. We also look at the Luminance chart on the right and the Luminance DeltaE box second from top on the left. What this tells us is that the majority of the primary and secondary colours are low in brightness to what they should be for correct playback of HD and Pal material. The other DeltaE boxes also show us the error levels for colour, hue and overall at the top left box. What we are looking for here are errors to be at least lower than 4 for an excellent performance and under 2 for reference.
So, as you can see looking at the CIE chart the native colour gamut of the projector is for the most part under saturated for Green, oversaturated for Red and within a smidge of being correct for blue. The secondary colours are for the most part slightly under saturated but with larger hue errors. As all the errors are quite large they will be seen by the eye. So can we correct any of these issues? One important thing to point out here is that because the native gamut is under saturated for Green by some margin, we cannot add back what is not there. So, we will have to accept that Green is going to remain an issue. We can however look at the other points and in particular the luminance issues and if the 3D Colour Management tool works as it should, we might be able to get the errors for the majority of the other colour points correct.
Greyscale controls for a manual calibration are not available on the W1000, so the only thing we have been able to do is use the contrast and brightness controls to get a slightly more accurate feel to the Greyscale, but that is all we could do. It is just fortunate that the out of the box settings used above gave us a good result. There is nothing else we could do to correct this further but with errors under 2dE it shouldn’t be a visible issue.
Moving to the colour gamut we do have a very basic colour management system to try and dial in some improvements. As explained above regarding the native colour gamut there is not a lot we could do with the green under saturation, but with some careful set up with what is a poor CMS (but it is a cheap projector), we managed to at least balance the gamut a little closer to the standards with some slight compromises. The most important part we could correct was the colour luminance and bring that back to where it should be, however, we did have to compromise slightly with colour and hue errors. Given that the CMS included with the projector is more of a marketing ploy than an actual useful tool, I was happy with the final results which shouldn’t cause any major issues with picture quality on playback.
For example areas of Chapter 48 on the King Kong BD brought up the limitations of the W1000 with areas of dark buildings on the New York street melding into one shade of black, rather than offering distinctive gradations of the lower black levels. When you add in some ambient light to the equation (with obvious results) the contrast ratio reduces by some margin. If you have a bright living room and don’t want absolute critical film watching performance, I doubt you would complain with the black detailing issues and lack of overall contrast performance. One area where the W1000 doesn’t offend is its colour reproduction given the reduced nature of its native gamut. In calibrated mode skin tones were extremely natural and detailed with primary colours handled without any issues that would stand out as being wrong.
Indeed apart from subdued greens on grass fields the overall colour performance was very acceptable and offered good gradation between various hues of colour. There was some signs of posterisation and banding from time to time, but no more than expected and certainly nothing that detracts from the overall performance at the price level. Watching a variety of formats and material from disc to TV signals, the overall performance of the W1000 stands up with its rivals such as the Mitsubishi HC3800. However, it does miss out some features such as anamorphic stretch.
- Compact enough to use as an occasional display
- Excellent value for money
- Good greyscale performance out of the box
- Good black levels at the price point
- Good colour performance, if a little limited gamut wise
- Noisy fan
- 3D CMS has limited use
- No manual greyscale controls
- Rainbow effect is quite noticeable
- Lack of lens shift, means limited placement options
