Samsung UN100M90HFXZA VESA pattern and wall-mount specs
The Samsung UN100M90HFXZA — the 100-inch Mini LED M90H — uses a 600 x 400 mm VESA pattern and weighs 121.2 lb (55 kg) without its stand, according to Samsung's product page. Any wall mount whose range covers 600 x 400 and is rated for at least 121.2 lb will hold it.
Mount checklist for the UN100M90HFXZA
- 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: 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 Samsung 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 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' 100-inch TVs: Sony BRAVIA 3 II (117 lb, 600 x 400 mm); LG QNED evo Mini LED QNED84B (145.3 lb, 600 x 400 mm). All share this TV's pattern, so a mount chosen for one would fit them too.
Samsung's other 100-inch models here — Micro RGB R85H (600 x 400 mm, 132.9 lb), Neo QLED QN80H (600 x 400 mm, 129.8 lb) — all share its pattern, so the mount question is only about weight.
Among Samsung's 78 models here, 14 use 600 x 400 mm (18%); Samsung's most common pattern is 400 x 300 mm. It is a 2026 model, so the specs above come from a current listing.

Samsung's current US listing shows only the 100-inch size of the Mini LED M90H, so there is no sibling to compare. Other Samsung TVs are on the Samsung page.

Where to sit
A 100-inch 16:9 screen is 87.2 in wide and 49 in tall. It fills the SMPTE 30° view from 13 ft 7 in and THX's 40° cinema view from 10 ft. At this size 4K looks sharper than 1080p only from 13 ft or closer; beyond that, 20/20 eyes cannot tell the two apart. The 100-inch size page has the full table and every model at this size.
