as part of a test program I could try the good thing time .. After the trial period I was this even for 700, - available, I have not slammed shut. The EIA is absolutely unrealistic, quite honestly, who believes that, please, to 2200 - EIA with the equipment and resolution. In general, the device with more than 30dB too loud. DLP typically occur many DLP Blitzer or the rainbow effect is for this class of devices to high pronounced, this is more in the 500, - expected range. The lamp life is given the light output in order. The optics can focus very well. Unfortunately, the short-throw projector is due to the optics quite strong image or optical errors, which manifests itself in the corners, which has residual light components affecting the square image. The black level is not particularly the dynamic range below average. The FB is rock solid and the price is also not equal, it is not even illuminated. The part is 3D Ready, completely useless, a direct connection to the BD player not possible, the video signal must first be polished by a software then it goes to the Sygnal in the device that was me frankly too cumbersome, the result is rather poor , well for he was not bought. The warranty conditions are silly, pickup in the first year, after which it must be Gschickt to Oberhausen and then send him to the Netherlands, Epson and Sony have a full service that is ever an indication of poor service and we are talking about a 2000 - Beamer in Lowbudgetklasse this is of course unacceptable. I can not recommend the device, who has no place of you should look absolutely. And not everyone uses it at the whiteboard, particularly schools, which use as a product that can wait for a warranty claim weeks!
