The LG CineBeam HU715Q 4K Ultra Short Throw projector makes use of a laser projection system to throw images as large as 120-inches onto your walls or projection screen.
Thanks to its short throw design, it can do this relatively discreetly too – it needs just about a 22cm distance from your wall to create an image 100-inches in size.
