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 are two HDMI ports so you can connect to multiple HD sources at the same time without swapping your cables around. There is also the older VGA connection. There is also a 10W built in speaker which will be suitable for a medium audience. With the P1350W having 3700 lumens, you will not have to clos the blinds whilst using the projector, you will be able to present with them open and even with the lights on.
The long lamp life will keep you from buying a replacement lamp anytime soon with its 15,000 hours. The keystone correction is a great feature becuase if you cannot install the projector directly centre of the screen, this feature will help you to still project in the middle.
