Sony K85XR30M2 VESA pattern and wall-mount specs
The Sony K85XR30M2 — the 85-inch BRAVIA 3 II — uses a 400 x 400 mm VESA pattern and weighs 78.8 lb (35.7 kg) without its stand, according to Sony's product page. Any wall mount whose range covers 400 x 400 and is rated for at least 78.8 lb will hold it.
Mount checklist for the K85XR30M2
- Pattern: 400 mm wide by 400 mm high (15.7 x 15.7 in). On a mount's box, both numbers must sit inside its range — "up to 400 x 400" fits this TV.
- Standard: a square Part F pattern in the VESA MIS standard, which uses M6 or M8 screws.
- Weight: 78.8 lb without the stand. Mounts are rated by maximum load; a mount rated 80 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
400 x 400 mm sits in the middle of the range most "medium to large" mounts cover — check that the mount's largest pattern is at least 400 wide and 400 tall, because some budget mounts stop at 300 x 300. At 78.8 lb it is a heavy set: plan a two-person lift, fix the mount into at least two studs or into masonry, and pick a mount whose rating leaves clear margin.
Closest in weight among other brands' 85-inch TVs: TCL QM7K (75.2 lb, 600 x 400 mm); LG QNED evo QNED92A (75 lb, 600 x 400 mm); Samsung Micro RGB R85H (75 lb, 600 x 400 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.
Sony's other 85-inch models here — BRAVIA 5 (400 x 400 mm, 102 lb), BRAVIA 7 II (400 x 400 mm, 101.2 lb), BRAVIA 9 II (400 x 400 mm, 106.2 lb) — all share its pattern, so the mount question is only about weight.
Among Sony's 46 models here, 6 use 400 x 400 mm (15%); 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 85-inch 16:9 screen is 74.1 in wide and 41.7 in tall. It fills the SMPTE 30° view from 11 ft 6 in and THX's 40° cinema view from 8 ft 6 in. At this size 4K looks sharper than 1080p only from 11 ft 1 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 85-inch size page has the full table and every model at this size.
