There’s consistently a little less vibrancy and dynamism than you get with the original Lumis, and also a fraction less shadow detail reproduction. But this says much more about the awesomeness of that projector than suggesting any real weakness in the Uno.
Since the Uno doesn’t have a dynamic iris, there’s no potential for the sort of distracting brightness 'jumping' that dynamic irises can cause. Though to be honest, we didn’t really see any evidence of this on the original Lumis either!
While the extreme dynamism of the Uno’s pictures might be the most instantly obvious stamp of its premium nature, it is the colour response of its pictures that you grow to love over the longer term. The combination of vibrancy and delicacy portrayed with a good Blu-ray is really quite exquisite - well beyond the abilities of the mainstream market.
So wrapped up will you be in the strengths already noted that it might take you a while to focus in on yet another good picture quality point: the Uno’s terrific sharpness. It reproduces every last nuance of a good HD signal with effortless accuracy, yet never pushes sharpness so hard that the picture starts to look noisy or 'digital'.
Motion looks completely natural too; fluid enough not to distract you with judder, yet not so fluid that it starts to look forced and processed. And it’s great to see the three-chip DLP engine rendering motion and camera pans with no sign at all of the fizzing noise seen with single-chip DLP models.
The three-chip configuration also naturally precludes the Uno from another dreaded phenomenon of single-chip DLP models: the rainbow effect, where stripes of red, green and blue appear over very high-contrast parts of the picture, or in your peripheral vision.
Aside from the minor and entirely understandable picture step-downs from the all-conquering original Lumis, the only 'complaint' (if you can really call it that) we might raise about the Uno is that it runs a touch noisily, especially using the top lamp output setting. But it’s not shockingly bad by any means for such a barnstormingly bright projector, and in any case the noise should be something a good installer should be able to sort out with a bit of thought/effort.
The C3X Lumis Uno is another triumphant projector from SIM2. We had our concerns that compromising the Lumis in any way might be a mistake, and feared what the removal of iris controls might do to the Uno’s flexibility and performance. But actually the Uno remains impressively flexible when it comes to perfecting your home cinema experience, and most important of all, it’s still a truly fearsome performer.
Sure, it’s not quite as good as the more expensive original Lumis, and however much we try to cook our accounts, we still can’t get close to being able to afford one ourselves.
Still, while it might not be cheap enough for us to afford personally, the Uno will undoubtedly open the SIM2 projector door to a potentially healthy number of well-heeled punters for whom the original Lumis’ £26,000 price tag is just a step too high. And any projector that spreads the gospel of awesome big-screen home entertainment is just fine by us.
