150 iNCH TV Projector Viewing Distance and Screen Dimensions
For 150″ diagonal projection, a viewing distance (from screen surface to eyes) range of 15.0′ (or 180″) to 22.5′ (or 270″) is recommended for the best viewing experience.
Viewable rectangular screen dimensions for an exactly 150″ diagonal projection screen are 130.8″ wide by 73.5″ high. Actual screen width and height may vary by tenths of an iNCH either more or less, as screen size classes are rounded to the nearest whole iNCH. Bezel adds a bit more to overall screen size.
This 150 iNCH TV solution recommends a pairing of the new Hisense L9Q TriChroma RGB ultra short throw laser TV projector with a 150″ diagonal fixed-frame wall-mount ALR projection screen which requires assembly. The projector and screen are sold separately.
