LG 55UA7700PUB VESA pattern and wall-mount specs
The LG 55UA7700PUB — the 55-inch UHD UA77 — uses a 200 x 300 mm VESA pattern and weighs 22.7 lb (10.3 kg) without its stand, according to LG's product page. Any wall mount whose range covers 200 x 300 and is rated for at least 22.7 lb will hold it.
Mount checklist for the 55UA7700PUB
- 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: 22.7 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.
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 22.7 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.
