WXGA resolution can be used for most things such as presentations, images and videos/movies. It will give you a clear and sharp image all day. Also, with widescreen you get 30% more viewing area than the standard XGA resolution; most modern devices are widescreen so you will match the aspect ratio.
The high contrast ratio will give your presentation more depth and will really show off the darker areas. It has a wide throw ratio so you have quite a bit of flexibility when mounting the unit. The long lamp life will sure keep you going with 15,000 hours! There is the modern HDMI connection so you will be able to connect to most sources and show your content in high definition. There is also the older VGA connection.
Overall, this is a great little projector that has the basics you will need.
