The Short Throw Projector CP-CX251n is obviously a very reliable machine with it being a Hitachi product. This model will be suitable for education and businesses. The LCD technology offers a stunningly clear image on the wall and at such a short distance too with it being a short throw projector. The short throw lens allows the CP CX251N to produce a 100" image from just 1.2m away. One of the downsides to LCD projectors is that you have the hassle of changing filters, but Hitachi have tackled that with the CP-CX251N giving it a Hybrid Filter so it lasts much longer than conventional filters, and with a lamp life of up to 10,000 hours in Eco mode, replacement lamps are few and far between too. The XGA (1024x768) resolution ensures a crisp image with sharp details to keep the class engaged. This projector comes with the modern HDMI connection to show your content in high definition and also has two VGA ports so you can connect to multiple devices at the same time without swapping cables around.
