Next on our tick list is how pleasingly little the HD20 is affected by a couple of traditional DLP problems: the rainbow effect, and motion fizzing.
Regarding the rainbow effect (which finds stripes of pure red, green and blue flitting about in your peripheral vision), while the HD20 certainly isn’t immune to it, it’s much less overt and distracting than it was on the Vivitek H1080FD we looked at recently.
Some people are, we know, more susceptible to seeing the rainbow effect than others. But I’d say that you’d have to be really very susceptible to it for it to become a real, regular problem on the HD20.
As for motion fizzing, where camera pans and objects – especially people – crossing the screen can cause some quite aggressive dot crawl noise, I only spotted this happening to any distracting extent four or five momentary times during the numerous hours I spent watching the HD20. Not bad when I’ve seen other budget DLP models suffer with this problem nearly continually.
The only definite performance weakness to report, in fact, is that the projector – hardly surprisingly, it has to be said – is very prone to judder when showing rapid motion or camera pans in a way more expensive projectors like Sony’s VPL-HW15 usually are not.
If you’ve read the main review carefully, you’ll have noticed that pretty much every time I’ve praised the HD20, it’s been along the lines of it being better than expected for its money, rather than suggesting that it represents the last word in projection excellence.
I want this to be totally clear, because I don’t want die-hard AV aficionados to think the HD20 is so good it makes redundant the idea of spending more money (if you’ve got it) to get something better.
Having cleared that up, though, there’s simply no denying that the HD20 shifts the goalposts of what I’d considered possible on a £900 DLP projector, and in doing so opens the quality big screen home cinema door to a whole new budget market. And that’s enough in itself to make the HD20 thoroughly deserving of a Recommended badge.
