Is a 100" TV right for your room?
Sold both as LCD TVs and as projector screens for ultra-short-throw projectors, so check which a 100-inch listing is. At 13 ft 7 in or less from the sofa it suits home theaters and very large rooms. Its screen is 9.8× the area of a 32-inch TV.
Allow at least 88.7" of wall or cabinet width. With the screen centre at a seated eye height of about 42", the top edge sits near 67" from the floor.
