TCL 85X11K VESA pattern and wall-mount specs
The TCL 85X11K — the 85-inch X11K — uses a 400 x 400 mm VESA pattern and weighs 104.5 lb (47.4 kg) without its stand, according to TCL's product page. Any wall mount whose range covers 400 x 400 and is rated for at least 104.5 lb will hold it.

Mount checklist for the 85X11K
- 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: 104.5 lb without the stand. Mounts are rated by maximum load; a mount rated 110 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 TCL 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.
Body size: 74.3 x 42.6 x 1 in
TCL lists the 85X11K at 74.3 in wide, 42.6 in tall and 1 in deep without its stand (189 x 108 cm), and 74.3 x 44.2 x 16.5 in on its stand — the stand adds 1.6 in of height and needs a surface 16.5 in deep. On the wall it stands out 1 in plus the mount's own profile. Compare it with every other 85-inch body on the above-a-fireplace and TV-cabinet pages.
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 104.5 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' 85-inch TVs: Sony BRAVIA 9 II (106.2 lb, 400 x 400 mm); Sony BRAVIA 5 (102 lb, 400 x 400 mm); Sony BRAVIA 7 II (101.2 lb, 400 x 400 mm). All share this TV's pattern, so a mount chosen for one would fit them too.
TCL's other 85-inch models here — QM6K (600 x 400 mm, 71.8 lb), QM7K (600 x 400 mm, 75.2 lb), QM8K (600 x 500 mm, 85.8 lb), QM7L (600 x 400 mm, 72 lb) — all use a different pattern, so check the exact model before buying a mount.
Among TCL's 46 models here, 5 use 400 x 400 mm (12%); TCL's most common pattern is 300 x 300 mm. It is a 2025 model still listed by TCL.
Other sizes in the TCL X11K line
The pattern is not the same across the line: it changes from 400 x 400 mm on the 85" to 600 x 400 mm on the 98". 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.
