I need a projector especially for business presentations. So I was more than happy when I could replace my 10 year old beamer by this new projector. First, the design is wonderfully elegant with the white, no comparison to my old silvery part. Then: he is nice and light, which is a good idea if you have high wear several flights of stairs a projector and a laptop, may still be in a hurry. Included is a VGA cable, a CD and a manual. The first disappointment comes immediately: The device has an impressive mini-USB port, but unfortunately the manual says is not working. Adios operation with iPod or other mobile, unless you have complicated interconnection cable, which I do not possess. Well, what I was able to test the connection between my laptop and the Acer was with an HDMI cable and it worked perfectly and are really, really beautiful pictures. One can easily correct the slant. The lamp time is displayed, there is a very good menu to colors, backgrounds, etc. display. You can even freeze the picture with a Freeze button. And what has made me with my old (not of Acer) almost ver Beamer --- was the lamp. If you accidentally ausschaltete the lamp, she took 10 minutes until the picture was back. Oh what a joy to be allowed to wait in a loud impatient people out. There are two to three minutes. What a relief. The unit has just only optional Wi-Fi or USB, and therefore the options on the remote control are available, but do not function. This is solved a bit unfortunate, but understandable, that one does not build x different remote controls for different device types. I have certainly tried my Tablet 10 minutes if it is not yet going via USB, no, it does not. So I'll probably buy the corresponding intermediate pieces, so you can also play USB parts. 3D I have wg. lack of equipment can not test, but I do not need anyway. The processing is dibasic. One can thus really be seen everywhere. Very good. Overall, a great part. Will I be a real relief when working. Therefore, five stars.
