Where things get REALLY interesting with the Lumis 3D-S is when you start looking into what’s tucked inside that almost obscenely curvaceous bodywork. For starters, you’ve got all the key, uncompromising optical elements that have served Sim2 so well for so long in the 2D world. We’ve already touched on the projector’s use of three large-form DarkChip 4 DLP chipsets, but there’s also the matter of Sim2’s patented ALPHAPATH compact die-cast light engine, complete phenomenal light efficiency and precision glass optics throughout.
Sim2 has additionally re-designed the assembly of the 3D-S electronics to enhance its 3D performance, and has – slightly surprisingly – introduced some ‘PureMotion’ video processing. This includes modes designed to optimize motion reproduction with the various demands of movie and sports footage, but also includes a system designed to improve motion with 3D.
Perhaps the single most important trick of the 3D-S versus other Sim2 projectors is its ‘3D Triple Flash’ technology. Previously only found in commercial 3D cinema installations, Triple Flash ensures that each eye gets three ‘flashes’ of a 1080p/24Hz 3D Blu-ray image frame, resulting in an overall frame rate of 144fps. Three-chip DLP projection is currently the only projection technology capable of delivering such a huge frame rate, with most rival technologies being limited to 120fps.
This is massively important for two reasons. First and foremost, the Lumis 3D-S’ extreme refresh rate per eye should eliminate that most dreaded of domestic 3D phenomena, crosstalk. But also it should kick into touch another massive objection to active 3D technology: flickering.
When it comes to setting the Lumis 3D-S up, meanwhile, your installer has an almost infinite amount of flexibility to work with. This begins with the availability of three different lens throw options, but reaches its true high-end zenith with Sim2’s advanced Live Colours Calibration 2 software – a system so comprehensive that it’s possible to achieve what’s effectively colour tone perfection in even the most difficult of installation environments.
While we’re on the subject of colour calibration, we should add, too, that unlike an alarming number of 3D displays, the 3D-S automatically switches its colour settings to suit 3D when operating in 3D mode. What’s more, your installer doesn’t even need to manually configure 3D settings themselves; instead Sim2 has measured the impact of its 3D glasses (two pairs of which are included with the projector) on the colours of its projector’s pictures, so that the 3D-S can automatically calibrate its 3D settings by applying the necessary ‘shift’ values to the settings established for 2D by your installer. Neat.
The net result of all the Lumis 3D-S’ extreme efforts is, as we couldn’t help but reveal right at the top of this review, extraordinary. The thing that hit us the hardest right away, like a 3D lightning bolt, was the complete absence of any crosstalk from 3D pictures. Seriously, there just isn’t ANY of the telltale ghosting at all, even during infamous crosstalk-inspiring scenes like the lantern sequence in Tangled or the bike fight in Tron.
Even Panasonic’s VT30 plasma TVs can’t claim total immunity to crosstalk during such scenes, so the 3D-S can fairly claim to be the first genuinely crosstalk-free domestic 3D display. And there really is no overstating the positive impact this has on 3D pictures – especially when you’re talking about 3D images plastered across screens hundreds of inches across.
