I want a review after two weeks use, because there are not many for this device. However, the Acer H7530 D is almost identical from the technical details and my impressions broadly in line with the corresponding reviews. It should be a full HD projector at an affordable price and that's why I ordered the H 7531d through Amazon. In delivery included are a carrying case and cables for mobile use, but lacks HDMI cable. Commissioning is without any problems. But you should worry about these installation / mounting options, seat pitch and screen size in advance. The projector must be pretty much in the center of the canvas hanging because no horizontal keystone is present, the vertical keystone compensation works perfectly. By the 1.2x zoom, the distance projector screen can not be all that much varied. The geometric data can be found in detail the Acer website. The design including lighting is well done and by its white color and handy size makes it well below the ceiling. Connections including 2xHDMI are all common vorhanden.Ich used to connect the projector an affordable 15m HDMI cable. When directly connecting the cable more disturbances arrive as pictures, short cables are easy. After installation of a 4x2 HDMI splitter with integrated amplifier, I needed anyway, the problem was solved with the long cable. Now the most important thing: The picture for HD signals is just great (2.4m wide screen) and can be freely assigned to personal taste einstellen.DVD- and SD signals look good too, fall against HD but of course significantly. I like the default standard with activated BrilliantColor best. The room must be darkened in daylight. The difference between Eco and Normal mode is minimal, given the advantages (longer lamp life, lower possible power consumption, noise) I'll just use the Eco mode. It is still an aperture for better contrast available, whose meaning is not obvious to me. I see no effect, the shutter is slow and noisy, the function is not activated at the factory and I will not do that. The menu is concise, retained the settings. The speaker is only suitable for mobile use. The fan noise is clearly audible but for me, disturbing in quiet sequences. You have to pay particular attention to the extract side, good ventilation, the projector is very warm. Overall, the Acer H7531D exceeded my expectations, a great device. Addendum of 31/07/2011: Have now seen five months in use and quite a few films in the cinema and the projector device. I'm still very satisfied, only the contrast in dark scenes could better sein.Benutzt to the built-in panel it changes nothing, the picture is only darker overall. Addendum of 29/10/2012: Have now 600 operating hours on the clock. The device runs without any problems and is now one of the family. To take on other reviews regarding: I have never been able to discover any undesired effects in the picture. Occur only on DVDs poorer quality light flashes on, and when BluRays TV tuner not.
