To achieve the recommended viewing distances when viewing 300-inch (diag.) HD video image you'll need a room that is absolutely no less than 45 to 50 feet long, which would also readily accommodate the range of projectors and lenses needed to properly display a 300-inch (diag.) video image. You would need absolute control over all light in the room to guarantee that you can display a sufficiently bright image with good contrast. You will also need a fairly powerful lamp power to throw an image that size and still maintain a reasonable minimum SMPTE screen illuminance of 14 fL (preferably without using a screen with a gain greater than 1.3.) No matter how well-controlled a viewing environment, in order to properly display a 300-inch image with the requirements above will almost always put you in the upper price range of HD (home theater) projectors.
Speaking of upper price range, where price is truly no object, another option are the "2K"* and "4K"* digital cinema projectors [1] [2] [3] or large venue projectors that are capable of projecting video images on screens just shy of 1000 inches wide (≈ 1147 inches diagonally; PH ≈ 563 inches!)
*("2K" and "4K" refer to images with 2048 and 4096 horizontal pixel resolution, respectively.)

HI.There are a few Projectors that can project a 300 inch diagonal image if you have a large enough room to view it.
Which one did you have in mind ?

yes its true but.....
u hav to play around checking at which image size the projected image looks clear and bright.
at full 300 inch image will not be as clear as 270 for example
( im talkin about $200 home theather projectors)
for relly high quality n bright images u need $1k+ projectors who use powerful lamps.
