I just had another private meeting with JVC and the main technical guy was there.
Regarding the lens on the N5 and N7, the reality is that the lens is the same lens but which has been improved. In other words, JVC took the existing lens design and have made some improvements. Therefore, it is neither the same lens nor completely new, but is definitely better as compared with the lens on the existing eshift range
Furthermore, with respect to the prevously reported mosquito video noise, yes there was some instances of mosquito video noise, however I have also seen instances where there is none. I also do not remember seeing any mosquito video noise whatsoever with respect to the native 4K content that I myself put on yesterday. And further to this during my private meeting with JVC today I confirmed this fact.
I also have confirmed that there is also absolutely ZERO additional noise added when turning eShift 8K on with respect to the NX9.
The only instance of mosquito video noise that I have witnessed today is with respect to HD content being upscaled by the projector, which it is not recommended that you do anyway; it is best to feed the projector HD that is pre-upscaled optimally to 4K. And with respect to yesterday, since there was not the ability to have proper handson we don't know what exactly was the situation regarding what was being actually sent to the projector in all instances, so it is possible that native 4K content was being outputted to the projector as HD 1080p. We therefore need to be careful regarding making statements that indicate that the projector is at fault and that specifically the fault relates to inability to playback native 4K content without 'incurable' mosquito video noise.
Also, with respect to the luminance, this certainly looks like what you'd expect a 2,200 lumens projector to look like.
