A:AnswerThe dimension is diagonal; I was not aware of this when I purchased and was shocked to discover it was too small for the projector image, which runs off the edges. But live and learn... The height and length of the actual viewable screen is 96" x 72". Overall width of the unit is 102".
A:AnswerThe current models that are available on Best Buy.com are both 4:3 aspect ratio. The difference between the two models is the color of the case. M120UWV2 and the M120XWV2. (Black and White case color options)
A:AnswerAs far as what projector it depends on preference you can get a good projector from $200.00on up in the thousands all you need for this screen is a projector that can do up to 120" I have a 3000 lumens HD projector but also you need to consider the distance you need from the projector to the screen so depending on your budget and preference any projector that can project 120" will work.
