The BenQ also shares a trio of negatives with the HD20, though. The first of these is judder with 1080p/24 feeds. This really can be quite distracting at times, almost looking like a twitch, with the result that we actually preferred watching films on the W1000 with our Blu-ray player set to output 1080i.
The second shared flaw is the rainbow effect. As with the HD20, this is really quite low level for such a cheap DLP projector, and shows up barely at all if the footage you’re watching is predominantly bright and colourful. But it was definitely evident over the tried and trusted black and white sequence at the start of Casino Royale, wherever a really bright point, such as a desk lamp, sits against a predominantly black background.
Our W1000 had one further flaw all of its own, however - a slight colour inconsistency, which finds a marginal pinkish tone creeping into play down the right hand side. This is only obvious with nearly totally black images, though, and could even be a problem specific to our test sample. If you buy a W1000 and don’t see this colour inconsistency, feel free to say so in the Comments section.
Finally, I guess I’d better at least mention the W1000’s audio, seeing as it’s there. And actually, you know, it’s not as shockingly bad as I’d expected! There’s enough volume available to make the audio legible in even a pretty large room, vocals - male and female - sound surprisingly clean, and amazingly even a couple of explosions we threw the speaker’s way came out with a little punch and without causing total audio meltdown! It helps, too, that the speaker doesn’t have to compete with too much in the way of running noise.
When all’s said and done, the W1000 is pretty much equivalent in basic performance quality to the Optoma HD20. But it distinguishes itself to aficionados courtesy of its impressive fine-tuning flexibility.
So the choice is simple. If you’re not into tinkering, save yourself £100 and get the Optoma HD20. But if you can be bothered to go the extra mile with its extra calibration options, earning an incremental boost in picture quality for your trouble, fork out a bit extra for the W1000.
