Mount checklist for the 50UA7700PUB
- Pattern: 200 mm wide by 300 mm high (7.9 x 11.8 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: 18.3 lb without the stand. Mounts are rated by maximum load; a mount rated 20 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.
Body size: 43.7 x 25.4 x 2.4 in
LG lists the 50UA7700PUB at 43.7 in wide, 25.4 in tall and 2.4 in deep without its stand (111 x 65 cm), and 43.7 x 27.6 x 10.8 in on its stand — the stand adds 2.2 in of height and needs a surface 10.8 in deep. On the wall it stands out 2.4 in plus the mount's own profile. Compare it with every other 50-inch body on the above-a-fireplace and TV-cabinet pages.
What that means when you shop
200 x 300 mm sits in the middle of the range most "medium to large" mounts cover — check that the mount's largest pattern is at least 200 wide and 300 tall, because some budget mounts stop at 300 x 300. At 18.3 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: Samsung Smart UHD (18.6 lb, 200 x 200 mm); Samsung Mini LED M70H (18.7 lb, 200 x 200 mm); Vizio Quantum 4K (19.36 lb, 200 x 200 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.
Same mount, different model: LG's 50UT7550AUA (UT7550 UHD) also uses 200 x 300 mm and weighs 19.2 lb. A mount that suits the 50UA7700PUB suits it too, which is handy if you are choosing between them.
Among LG's 158 models here, 5 use 200 x 300 mm (3%); LG's most common pattern is 300 x 200 mm. It is a 2025 model still listed by LG.
