VESA patterns / 400 x 400
VESA 400 x 400 mm
A 400 x 400 pattern means four mounting holes 400 mm apart side to side and 400 mm apart top to bottom (15.7 x 15.7 in, a square). 23 TVs on this site use it, from 65 to 85 inches, weighing 57.1 to 110.9 lb without stand.
Where it sits in the VESA standard
400 x 400 is one of the square patterns in Part F of the VESA Mounting Interface Standard, the part for large displays, which specifies M6 or M8 machine screws. It is the number 6 of 12 patterns among the TVs listed here.
What kind of TV uses 400 x 400
400 x 400 is where mid-size mounts start to run out: a mount that stops at 300 x 300 won't reach these holes. Look for "up to 400 x 400" or "up to 600 x 400" on the box, and check the weight rating, since TVs with this pattern here run up to 110.9 lb.

Which mounts fit 400 x 400
A mount fits when the TV's pattern width and height both fall inside the mount's published range. For this pattern, the mount's largest pattern must be at least 400 wide and 400 tall, and its smallest no bigger than 400 x 400. A mount sold as "up to 600 x 400" covers it; one listed "up to 300 x 400" does not. Weight matters as much as the holes: the heaviest TV here with this pattern weighs 110.9 lb, so a mount rated below that will not do for it.
A mount that fits 400 x 400 usually also fits the smaller patterns inside it: 100 x 100, 200 x 200, 200 x 300, 300 x 200, 400 x 200, 300 x 300, 400 x 300 — as long as its minimum allows.
