“The N7 is pleasingly quiet in operation, measuring at just 20dB in low lamp mode and 28dB in high lamp mode. Since this is a native 4K projector there’s also no e-Shift device and thus no noise being caused by the device physically moving incredibly fast in front of the lens.
The N7 uses a 265W lamp and has a claimed brightness of 1,900 lumens, which is the same as our previous X7500 reference projector. The brightness appears comparable, but the contrast performance isn’t as good as the earlier generation. The N7 has a claimed contrast performance of 80,000:1, while the X7500 has a claimed contrast ratio of 130,000:1. The best we measured the N7 at is about 70,000:1, which is fairly close to JVC’s claimed numbers, but we immediately noticed that the contrast wasn’t quite as good as the X7500. ”
