If you guessed laser-LCD, you guessed right.
The new NEC 3LCD P525WL and P525UL projectors are WXGA (1280×800)and WUXGA (1920×1200), respectively, which are virtually silent at 22dB — this is like 10dB less than nearly every other projectors in their class. How quiet is that? Well, technically, a whisper is like 28dB. So, yes, these are quiet than a whisper. Oh, and they’re 5,000 ANSI lumens.
This matters. The secret sauce is a combination of using laser and very low power consumption.
As well as being near-noiseless, the P525 laser projectors can input signals up to 4K@30Hz (and obviously scales them), lasting over 20,000 hours of maintenance-free operation thanks to their laser light source. Furthermore, the optical laser LCD engine is completely sealed, meaning there is no need to change bulbs or filters over the projectors’ lifetime.
NEC’s latest projectors include connectivity via Wi-Fi with an embedded MultiPresenter function enables wireless presentation and screen-sharing for up to 16 devices simultaneously. They have an HDBaseT input, two HDMI ports and a VGA port.
Power consumption is just 330 watts in normal mode and 240 watts in eco-mode.
