Criticisms are that the projector is sensitive to what sources it depends. So he has automatically detected only right on Blu-ray player, the signal as a 3D - if the signal via the Denon AVR-X1100W was sanded no 3D device on 3D Blu-ray player has been detected. However, that was the Denon - according to a recent firmware update that was ok.
The projector shows me a sufficiently sharp image - as you can see on the test pattern, which is shown if no input signal. The optics is unfortunately very smoothly, and adjusted after some time - apparently after heating of the device - easy. It is therefore good image even clean einzujustieren - and some time to wait.
It is important also that you can measure times his room before buying. After the projector has a rather Schmallen setting, at a distance of about 3m a screen with 100-inch diagonal with me was just right. Please make the else can you experience surprises.
What was interesting was the fact that the CSL - ULTRA HD (4k) HDMI Splitter - I have hanging on the Denon divide the signal between the old Panasonic HDTV and projector em - only so did not want to go with the device. Only after moving it to the MHL port has the thing works suddenly, even in 3D at the same time on both units.
One should at all be aware that the recognition of the projector is required as a 3D device through the 3D Blu-ray Player - and between Switched devices can be a source of error always and looking for hours of errors and switching options force. But that's the price you pay for your home theater - together with the mounting of the canvas on the ceiling.
