The Acer S1283E is a short throw projector which is suitable for the office and classroom. Short throws are particularly suited for rooms which have limited space so you can still project a large image from a short distance away. It will also eliminate shadows on the screen. You will be also impressed with the high 3100 lumens brightness which means that you can project with the lights on and blinds open. The S1283E offers an XGA resolution of 1024 x 768 pixels in a 4:3 format. This will be suitable for Power Point, spreadsheets, images and short video clips. If you want to show movies, WXGA (widescreen) resolution is recommended as movies are widescreen so you will get good quality without compression. However, XGA will still give you a sharp image. The Acer S1283E has VGA connection so you can connect to laptops. Older video devices can be connected via S-Video and composite video. However, it doesn’t’ have the modern HDMI connection which newer devices have so you cannot show your content in high definition which is a disadvantage. There is also a 10W built in speaker which is suitable for a medium sized audience and you won’t have to attach any additional audio. Overall, this is an OK projector but missing some connections and also only comes with a 1 year warranty whereas other manufacturers have at least 2 or 3 years.
