SIM2 Nero 3D-2 Projector Review
On this page we take a look at the Nero 3D-2 projector’s brightness, sharpness, and image noise. We’ll discuss brightness in conjunction with 3D usage, as well. Also considered here are the physical attributes of light leakage and audible noise.
Settings for measurements (default values are in parenthesis):
These setting were applied to each of the color temps, when measured
All other settings at default (untouched)
Measurements taken with lamp at 280 (max) power setting unless otherwise noted..
SIM2 Nero 3D-2 Brightness
|Lumen Output and Color Temp at 100 IRE (mid zoom)|
|Standard||666 @ 7223|
|High||675 @ 10601|
|Medium||772 @ 8702|
|Low||637 @ 7456|
|Native||825 @ 8437|
|D75||729 @ 8726|
|D65||669 @ 7134|
|D50||586 @ 5603|
|C||610 @ 7817|
|User||637 @ 7448|
We’ll start of with Mike’s results measuring each of the many “preset modes”. Also included was the measured color temp for white, for each mode.
I didn’t really view the 3D-2 projector before Mike calibrated it, although I’ve flipped through the various Color Temp modes.
There isn’t a huge difference between calibrated results, and the brightest mode (Native), about 35%. Native mode was not bad looking at all, but definitely cool, with reds definitely a bit thin.
SIM2 Nero 3D-2 Brightness: Calibrated (zoom at mid-point): 605
SIM2 Nero 3D-2 Brightness: ” Brightest” mode – Native mode: 825
It is important to note that which lens is chosen does affect brightness. The T-2 lens provided to me, is not their brightest.
|Effect of zoom on lumen output (Native)|
The lens does not drop significantly in brightness, between wide and tele.
|Lumen Output at each lamp power setting (Native)|
The projector can be run in any of these six brightness settings. The fan pitch changes and the projector gets quieter as you lower the brightness.
|Color Temp over IRE Range, Best mode (D65)|
Not surprising for a premium projector, even the default grayscale is exceptionally consistent, although the measurements all hover right around 7100K, rather than the ideal 6500K.
|Effect of iris on lumen output (Native mode)|
|Iris on 100 (fully open)||825|
|Iris on 50 (mid range)||750|
|Iris 0n 0 (smallest opening)||644|
I was unable to ascertain if the effect of the manual closing of the iris, maintains or reduces the dynamic range of the image.
SIM2 Nero 3D-2 Projector - Post Calibration Greyscale
|Color Temp over IRE Range (User mode)|
Average gamma = 2.27
Lumens at 100 IRE: 605
Mike’s Notes: Grayscale calibration affects the full IRE range, but the RGB balance is so consistent across the range that excellent results can be achieved. The color temperature choices and white point adjustments are listed as color management, but there is no true color management available, at least not in the menu. The Rec. 709 CIE chart shows accurate primary colors, while the secondaries are slightly off.
The Calibration page provides the settings we used. That includes basic settings as well as gain and offset.
