Pleasantly the fan noise, which is as good as not to be heard in the Lamp Setting Eco. Eco is sufficient in most cases only in a bright environment it is helpful to full lamp power to switch.
With so much light there a downside? Yes and that is the black level - put on so many others here value - surprisingly well despite the high light output.
The 3-D effect is blameless, since the image is perceived darker by the shutter glasses are also here the 3500 Ansi lumens very reasonable.
Forget big LCD - TV, Beamer this combined with a 4m screen in the diagonal, produced a true big-screen and real home theater.
In addition there was the projector here in the Christmas special sale for a mere 499 .-- Euro, which would be the merchant again separately.
So I can really recommend this beamer, he gets along well with wireless HDMI transmitter, which the Benq Th681 does not. I had two weeks earlier also bought him here for 499 .-- and had to return it because it is incompatible with Wireless HDMI him.
There is nothing bad without is something good here, because then there was the Acer in the special sale with whom I made a real leap forward in terms of light output, because I came of 2000 ANSI lumens with my old projector and the specified 3000 ANSI lumens of Benq were not convincing.
In Acer H6520 now puts a much More powerful lamp and that is clearly visible. However, with around 300Watt power consumption can be expected.
