Samsung QN55S90HAEXZA VESA pattern and wall-mount specs
The Samsung QN55S90HAEXZA — the 55-inch OLED S90H — uses a 300 x 200 mm VESA pattern and weighs 32.2 lb (14.6 kg) without its stand, according to Samsung's product page. Any wall mount whose range covers 300 x 200 and is rated for at least 32.2 lb will hold it.
Mount checklist for the QN55S90HAEXZA
- Pattern: 300 mm wide by 200 mm high (11.8 x 7.9 in). On a mount's box, both numbers must sit inside its range — "up to 400 x 400" fits this TV.
- 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: 32.2 lb without the stand. Mounts are rated by maximum load; a mount rated 40 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
300 x 200 mm sits in the middle of the range most "medium to large" mounts cover — check that the mount's largest pattern is at least 300 wide and 200 tall, because some budget mounts stop at 300 x 300. At 32.2 lb it is a two-person lift onto the mount, and well inside the rating of mainstream fixed and tilting mounts; on a full-motion arm, check the rating at full extension.
Closest in weight among other brands' 55-inch TVs: Sony BRAVIA 6 OLED (30.2 lb, 300 x 200 mm); Sony BRAVIA 3 II (29.4 lb, 300 x 300 mm); TCL QM7K (29.3 lb, 300 x 300 mm). 1 of them shares this TV's pattern.
Same mount, different model: Samsung's MRN55R85HAFXZA (Micro RGB R85H, 2026) also uses 300 x 200 mm and weighs 32.2 lb. A mount that suits the QN55S90HAEXZA suits it too, which is handy if you are choosing between them.
Among Samsung's 78 models here, 9 use 300 x 200 mm (12%); Samsung's most common pattern is 400 x 300 mm. It is a 2026 model, so the specs above come from a current listing.
Other sizes in the Samsung OLED S90H line
