VESA patterns / 400 x 300

VESA 400 x 300 mm

A 400 x 300 pattern means four mounting holes 400 mm apart side to side and 300 mm apart top to bottom (15.7 x 11.8 in, wider than it is tall). 28 TVs on this site use it, from 55 to 85 inches, weighing 37.9 to 82.9 lb without stand.

Where it sits in the VESA standard

400 x 300 is a rectangular pattern. The standard's large-display table (Part F) lists square patterns from 200 to 1000 mm, but TV makers commonly use rectangles like this one, and wall mounts are sold by the range of patterns they accept, so it mounts like any other pattern of its size. At this size the screws are usually M6 or M8 — the TV's manual is the authority. It is the number 2 of 12 patterns among the TVs listed here.

What kind of TV uses 400 x 300

400 x 300 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 82.9 lb.

Which mounts fit 400 x 300

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 300 tall, and its smallest no bigger than 400 x 300. A mount sold as "up to 600 x 400" covers it; one listed "up to 300 x 300" does not. Weight matters as much as the holes: the heaviest TV here with this pattern weighs 82.9 lb, so a mount rated below that will not do for it.

A mount that fits 400 x 300 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 — as long as its minimum allows.
