TCL 75QM8K VESA pattern and wall-mount specs
The TCL 75QM8K — the 75-inch QM8K — uses a 400 x 400 mm VESA pattern and weighs 62.6 lb (28.4 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 62.6 lb will hold it.
Mount checklist for the 75QM8K
- 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: 62.6 lb without the stand. Mounts are rated by maximum load; a mount rated 70 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
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 62.6 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' 75-inch TVs: Sony BRAVIA 2 II (61.7 lb, 300 x 300 mm); Samsung Neo QLED QN1EH (64.4 lb, 400 x 400 mm); Samsung Neo QLED QN70H (64.4 lb, 400 x 400 mm). 2 of them share this TV's pattern.
TCL's other 75-inch models here — QM6K (300 x 300 mm, 50.7 lb), QM7K (300 x 300 mm, 54.2 lb) — all use a different pattern, so check the exact model before buying a mount.
Among TCL's 15 models here, 1 uses 400 x 400 mm (7%); TCL's most common pattern is 300 x 300 mm. TCL's page doesn't state the model year.
Other sizes in the TCL QM8K line
The pattern is not the same across the line: 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 75" to 600 x 500 mm on the 85". A mount bought for one size is not automatically right for another.

Where to sit
A 75-inch 16:9 screen is 65.4 in wide and 36.8 in tall. It fills the SMPTE 30° view from 10 ft 2 in and THX's 40° cinema view from 7 ft 6 in. At this size 4K looks sharper than 1080p only from 9 ft 9 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 75-inch size page has the full table and every model at this size.
