The brightest mode, called Bright, measured at 4,806 lumens. The next brightest mode – Blending – came in at 4,361 lumens. If you recall from the previous page, Bright Mode had better color than the less-bright Blending Mode, which works in your favor if you’ve got a lot of ambient light to deal with, such as may be the case in either a museum exhibit or a small entertainment venue (stage lighting).
A quick note if you’re using this projector for an entertainment venue – if you mount the lights behind the projector, and do your best to keep the lights from directly hitting your screen surface, you’ll have a better time with your projections.
Presentation Mode and DICOM SIM. measured rather close to one another, with Presentation coming in at 3,889 lumens, while DICOM SIM. (x-ray films) measured at 3,833 lumens. Presentation will likely be the most used of the brightest modes, as it has the best color of these higher measurements. Still, in a pinch, even Bright has pretty good color compared to some other projectors’ brightest modes, and with the Color Management System, I’m sure you could get even better color out of any of the modes on the ZU660.
The final two modes are Movie and sRGB. These two modes have generally the same color, with minor differences, but a huge difference in brightness. Movie Mode measured at 2,750, and sRGB only measured at 1,694. I would choose Movie Mode over sRGB for that alone, but 1,694 lumens can handle some moderate ambient light on my 92” screen. The large the screen, though, the less bright the projector will seem. Keep that in mind when choosing your modes.
