The extra calibration assistance offered by the Nero 3D-2‘s dimmable iris feature also played a part in the way the projector pulls out that bit more finesse and subtlety with dark material.
While the extra brightness and contrast of the Nero 3D-2 might be at their most obvious with 3D, though, they do also make their presence felt with HD 2D. There’s more pop to colours, white areas look slightly purer, and dark areas have a bit more depth and richness.
The extra brightness also seems to enhance the stunning sense of detail and texture in the image - something which reveals, too, the exceptional clarity and quality of the optical engine Sim2 uses in its Nero models. It’s this astounding sharpness and purity more than anything else that makes watching old favourite Blu-rays on the Nero 3D-2 feel like you’re watching them for the very first time.
There are a couple of issues with the projector's performance. The rainbow effect you can get with single-chip DLP projectors - where stripes of red, green and blue flit almost subliminally around bright parts of the picture - is if anything slightly more evident on the Nero 3D-2 than it was on the Nero 3D-1, presumably because of its extra brightness. But the phenomenon still only crops up very rarely, and there’s a good chance many people won’t see it at all.
The Nero 3D-2 also runs a bit noisily, especially in 3D mode - though a good installer should be able to mitigate this to some extent by where they position the projector.
Other than that, our only complaints would be that a) it's a shame you don't get any 3D glasses or the transmitter included free with the projector (a 4-glasses pack will cost you around £750) and b) it’s high time Sim2 improved the remote control it ships with its projectors, as the current item feels too plasticky and unergonomic to go with such a high-end projector.
We guess we’re duty bound to point out that the Nero 3D-2 doesn’t reach the same dizzying heights as the Lumis 3D-S when showing either 2D or 3D. But then it only costs half as much.
Rather more pertinent is the way that, aside from some marginally greater rainbow effect, the Nero 3D-2 delivers a marked improvement over the Nero 3D-1 - so much so that within the context of five-figure projectors, the extra £3,000 it costs really doesn’t seem much of a stretch at all for such a significant performance enhancement.
