TCL 98QM8K VESA pattern and wall-mount specs
The TCL 98QM8K — the 98-inch QM8K — uses a 600 x 500 mm VESA pattern and weighs 121.2 lb (55 kg) without its stand, according to TCL's product page. Any wall mount whose range covers 600 x 500 and is rated for at least 121.2 lb will hold it.
Mount checklist for the 98QM8K
- Pattern: 600 mm wide by 500 mm high (23.6 x 19.7 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: 121.2 lb without the stand. Mounts are rated by maximum load; a mount rated 130 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 500 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 121.2 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' 98-inch TVs: Samsung The Frame LS03HE (124.3 lb, 600 x 400 mm); LG Nano NU850 (110.2 lb, Not published); Sony BRAVIA 7 II (137.1 lb, 600 x 400 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.
Same mount, different model: TCL's 98QM7K (QM7K) also uses 600 x 500 mm and weighs 119.7 lb. A mount that suits the 98QM8K suits it too, which is handy if you are choosing between them.
Among TCL's 15 models here, 4 use 600 x 500 mm (27%); 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 98-inch 16:9 screen is 85.4 in wide and 48 in tall. It fills the SMPTE 30° view from 13 ft 3 in and THX's 40° cinema view from 9 ft 9 in. At this size 4K looks sharper than 1080p only from 12 ft 9 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 98-inch size page has the full table and every model at this size.
