Samsung QN55LST7DAFXZA VESA pattern and wall-mount specs
The Samsung QN55LST7DAFXZA — the 55-inch The Terrace LST7D (Partial Sun) — uses a 200 x 200 mm VESA pattern and weighs 64.6 lb (29.3 kg) without its stand, according to Samsung's product page. Any wall mount whose range covers 200 x 200 and is rated for at least 64.6 lb will hold it.
Mount checklist for the QN55LST7DAFXZA
- Pattern: 200 mm wide by 200 mm high (7.9 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 square Part F pattern in the VESA MIS standard, which uses M6 or M8 screws.
- Weight: 64.6 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 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
A 200 x 200 mm pattern is at the small end for TVs: nearly every TV wall mount covers it, including compact fixed plates and single-stud swing arms, so the deciding number is weight, not holes. At 64.6 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' 55-inch TVs: LG Gallery TV LX7 Mini LED (41 lb, 400 x 300 mm); Sony BRAVIA 7 II (40.6 lb, 300 x 300 mm); Sony BRAVIA 5 (39 lb, 300 x 300 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.

Among Samsung's 78 models here, 18 use 200 x 200 mm (23%); Samsung's most common pattern is 400 x 300 mm. Samsung's page doesn't state the model year.
Other sizes in the Samsung The Terrace LST7D (Partial Sun) line
The pattern is not the same across the line: it changes from 200 x 200 mm on the 55" to 400 x 400 mm on the 65". A mount bought for one size is not automatically right for another.

Where to sit
A 55-inch 16:9 screen is 47.9 in wide and 27 in tall. It fills the SMPTE 30° view from 7 ft 5 in and THX's 40° cinema view from 5 ft 6 in. At this size 4K looks sharper than 1080p only from 7 ft 2 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 55-inch size page has the full table and every model at this size.
