Our Score:


One thing becomes apparent with the H1085’s pictures right away, and that’s that they suffer way less with the rainbow effect than those of the H1080 I tested.

My favourite test sequence for spotting 'rainbowing' is, as regular readers will know, the opening black and white sequence from Casino Royale. (Although any number of text-heavy game menu screens, like the player lists in the pre-game lobbies of Modern Warfare 2 online, also work well.)

And with the H1085 I found myself substantially less affected by the familiar stripes of pure red, green and blue flitting around over the bright parts of the picture than I’d expected to. The issue certainly isn’t completely invisible; flitting my eyes over the screen definitely reveals it. But crucially it’s now low-level enough to seldom be a real distraction to the majority of people.

As always, I should say that some people are more susceptible to the rainbow effect than others, so there may still be a few folk who can’t live with the H1085’s level of the problem, and should consider an LCD model like Epson’s impressive TW2900 instead. But I really don’t think this situation will apply to many people.

The H1085 also greatly outguns the H1080 with its black level response, as dark scenes suffer less with the slightly grey, crushed, detail-light look noted with the cheaper model. What’s more, as hoped the H1085’s greater brightness works in harmony with the enhanced contrast range to make images during dark and bright scenes alike look more punchy and engaging, even after calibration.

The H1085’s post-calibration colour palette looks more consistently accurate than that of the H1080 too, while detailing and sharpness are at least as acute. In fact, the extra ‘snap’ to the picture created by the boosted brightness and contrast performance arguably makes the H1085’s HD pictures look slightly crisper.

Aside from the residual rainbow effect mentioned earlier, the only other real problems I have with the H1085 are that it runs rather noisily if you make the mistake of leaving the lamp in its Boost mode; that there’s noticeable (though not unbearable) judder during 1080p/24 viewing; and that dark parts of the picture are slightly ‘alive’ with the greyish green dot crawl that’s still common with DLP projectors. Oddly, though, while this must certainly impact black level response to some extent, you only really become conscious of its existence if you get really close to your screen, or when a scene contains a lot of low-level green colouring.


These really are exciting times to be buying a budget projector. For as with a number of rival models we’ve seen recently, while the H1085 certainly doesn’t entirely shake off the inevitable shackles of its low price, it’s still astonishingly watchable and ambitious for its money. In fact, for me the way it manages to deliver brightness and contrast while still reining in DLP’s rainbow effect actually makes it the pick of the current sub-£1k projector crop.

Please be aware that this does not appear to be an LED projector, from the lamp life and reference to lamp this appears to be a standard DLP projector not an LED projector.

Must admit, the current crop of budget projectors are really starting to tempt me. They're now price competitve with, say, a good quality 42 or 46 inch plasma (the latest Panasonic sets spring to mind) so I guess it's a question of whether outright picture quality or screen size is more important. I suspect at the moment I'm more likely to come down on the TV side as there's still too many usability issues with projectors for my liking (noise, need to replace bulbs, cables running a LONG way round the room to reach the projector and of course the need to keep the room dark being the main ones) and once you've factored in a decent screen it's still up over a grand. But good lord it's getting tempting now...

@Gasper - deleted LED from the title. Cheers!

Yea the LED bit has me foxed too! I was wondering where the advantage of the 'LED' system was with a lamp life of 4000hrs..... Now it makes sense thanks to Gasper!


Don't forget you'll also need some audio - and for movies probably 5.1 surround plus an HTPC and tv card to drive it (the PJ) etc....
