Color The first and foremost thing is when you’re buying a projector for educational purpose for your school, consider the picture – it should give images that attractive to the learners.

Contrast ratio A high-contrast ration makes the image rich, and clear in detail. LCD technology can provide contrast ration up to 200000:1 How easy it is Make sure to check it has a feature of getting on/off as soon as it is triggered. Easy connection to audio is important. Resolution Resolution is the number of dots in an image. Higher resolution gives better quality image and lower resolution gives low quality image. Resolution comes in two types: XGA, SVGA, WXGA and HD in one set. The other set is the number of vertical and horizontal pixel lines that the projector is making. SVGA corresponds to 800 x 600, XGA to 1024 x 768. Thus, if you opt for SVGA projector, it will bring you great images of 800 pixel wide and 600pixel height. Connectivity Check whether the projector is compatible with USB device, and has display port which is important for connecting computers, televisions, and DVD players. Interaction In the classroom, interaction is important to make learning engaging. Interactive ability of the projector help you show and explain the content from diverse sources and create big or small interactive areas using interactive devices (interactive pens). Distance and positioning The throw distance of a projector is the distance between the projector and image. Choose short throw, long throw or ultra short throw depending on the size of the room where the projector is played. Image adjusting Check if automatic adjustment is available. You need not go to the menu to change the setting and adjust. When the projector is not placed centrally it may result in images tilted to one side. The lens, image quality correction etc. should be there. Easy to use and maintenance Check the ease and convenience of operation maintenance. Further, check the post sales service is available. Find how often they do it. Also, check if warranty for the product is offered.
