Mount checklist for the 55UA7700AUA
- 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: 25.4 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.
Body size: 48.7 x 28.3 x 2.7 in
LG lists the 55UA7700AUA at 48.7 in wide, 28.3 in tall and 2.7 in deep without its stand (124 x 72 cm), and 48.7 x 30.7 x 9.1 in on its stand — the stand adds 2.4 in of height and needs a surface 9.1 in deep. On the wall it stands out 2.7 in plus the mount's own profile. Compare it with every other 55-inch body on the above-a-fireplace and TV-cabinet pages.
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 25.4 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.
