TCL 85QM6K VESA pattern and wall-mount specs
The TCL 85QM6K — the 85-inch QM6K — uses a 600 x 400 mm VESA pattern and weighs 71.8 lb (32.6 kg) without its stand, according to TCL's product page. Any wall mount whose range covers 600 x 400 and is rated for at least 71.8 lb will hold it.
Mount checklist for the 85QM6K
- 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: 71.8 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 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.
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 71.8 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: Samsung Neo QLED QN80H (70.8 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). All share this TV's pattern, so a mount chosen for one would fit them too.
TCL's other 85-inch models here — QM7K (600 x 400 mm, 75.2 lb), QM8K (600 x 500 mm, 85.8 lb) — use a mix of patterns, so check the exact model before buying a mount.
Among TCL's 15 models here, 2 use 600 x 400 mm (13%); TCL's most common pattern is 300 x 300 mm. TCL's page doesn't state the model year.
Other sizes in the TCL QM6K line
The pattern is not the same across the line: it changes from 300 x 300 mm on the 75" to 600 x 400 mm on the 85", and it changes from 600 x 400 mm on the 85" to 600 x 500 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.
