Is a 45" TV right for your room?
Rare as a TV. The size is better known for 21:9 ultrawide monitors, which are much shorter than a 16:9 TV with the same diagonal. At 6 ft 1 in or less from the sofa it suits typical bedrooms and smaller living rooms. A 45-inch 21:9 ultrawide is 41.4" × 17.7", so 4.3" shorter than this 16:9 screen.
Allow at least 40.7" of wall or cabinet width. With the screen centre at a seated eye height of about 42", the top edge sits near 53" from the floor.
