Mount checklist for the 50UA7700AUA
- 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: 20.7 lb without the stand. Mounts are rated by maximum load; a mount rated 30 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 LG 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.
LG's page prints 44.2 x 28.3 x 2.7 in without the stand and 29.9 in tall with it, a body 3 in taller than the other 50-inch LG sets and a stand only 1.6 in taller, so no body size is shown.
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 20.7 lb this is a light TV — one person can hold it while another hooks it on, and almost any mount for its pattern is rated well above it.
Closest in weight among other brands' 50-inch TVs: Vizio Mini LED Quantum 4K (20.06 lb, 400 x 300 mm); Sony BRAVIA 2 II (21.6 lb, 200 x 200 mm); TCL Q651G (19.6 lb, 300 x 300 mm). 1 of them shares this TV's pattern.
Same mount, different model: LG's 50QNED70AUA (QNED70A, 2025) also uses 200 x 200 mm and weighs 21.6 lb; LG's 50UA7000PUB (UHD UA7000, 2025) also uses 200 x 200 mm and weighs 20.7 lb. A mount that suits the 50UA7700AUA suits them too, which is handy if you are choosing between them.
Among LG's 158 models here, 16 use 200 x 200 mm (11%); LG's most common pattern is 300 x 200 mm. It is a 2025 model still listed by LG.

Where to sit
A 50-inch 16:9 screen is 43.6 in wide and 24.5 in tall. It fills the SMPTE 30° view from 6 ft 9 in and THX's 40° cinema view from 5 ft. At this size 4K looks sharper than 1080p only from 6 ft 6 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 50-inch size page has the full table and every model at this size.
