Sony K100XR30M2 VESA pattern and wall-mount specs
The Sony K100XR30M2 — the 100-inch BRAVIA 3 II — uses a 600 x 400 mm VESA pattern and weighs 117 lb (53.1 kg) without its stand, according to Sony's product page. Any wall mount whose range covers 600 x 400 and is rated for at least 117 lb will hold it.
Mount checklist for the K100XR30M2
- Pattern: 600 mm wide by 400 mm high (23.6 x 15.7 in). On a mount's box, both numbers must sit inside its range — "up to 400 x 400" fits smaller TVs, but not this one.
- Standard: a rectangular pattern outside the square Part F table, which is normal for current TVs; screws are usually M6 or M8 at this size, but the manual is the authority.
- Weight: 117 lb without the stand. Mounts are rated by maximum load; a mount rated 120 lb or more leaves no doubt, and full-motion arms should have more margin than fixed plates because the load sits further from the wall.
- Screws: use the screw length and any spacers the Sony manual specifies. Too long can damage the panel; too short strips the insert.
- Wall: fix the mount to studs or masonry with the hardware the mount maker supplies for that wall type.
What that means when you shop
600 x 400 mm needs a mount sold for large TVs; compact and "up to 400 x 400" mounts will not reach the holes. Large fixed and tilting mounts usually cover it, and most heavy-duty full-motion arms do. At 117 lb this is a very heavy set: it needs a heavy-duty mount, fixings into studs or masonry, and three people or a professional installer to lift it safely.
Closest in weight among other brands' 100-inch TVs: Samsung Mini LED M90H (121.2 lb, 600 x 400 mm); Samsung Neo QLED QN80H (129.8 lb, 600 x 400 mm); Samsung Micro RGB R85H (132.9 lb, 600 x 400 mm). All share this TV's pattern, so a mount chosen for one would fit them too.
Among Sony's 46 models here, 3 use 600 x 400 mm (8%); Sony's most common pattern is 300 x 300 mm. It is a 2026 model, so the specs above come from a current listing.
Other sizes in the Sony BRAVIA 3 II line
The pattern is not the same across the line: it changes from 200 x 200 mm on the 43" to 300 x 300 mm on the 50", and it changes from 300 x 300 mm on the 65" to 400 x 400 mm on the 75", and it changes from 400 x 400 mm on the 85" to 600 x 400 mm on the 100". A mount bought for one size is not automatically right for another.

Where to sit
A 100-inch 16:9 screen is 87.2 in wide and 49 in tall. It fills the SMPTE 30° view from 13 ft 7 in and THX's 40° cinema view from 10 ft. At this size 4K looks sharper than 1080p only from 13 ft or closer; beyond that, 20/20 eyes cannot tell the two apart. The 100-inch size page has the full table and every model at this size.
