Mount checklist for the 75UA7700AUA
- Pattern: 400 mm wide by 400 mm high (15.7 x 15.7 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: 60.2 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 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: 66.1 x 38 x 2.4 in
LG lists the 75UA7700AUA at 66.1 in wide, 38 in tall and 2.4 in deep without its stand (168 x 97 cm), and 66.1 x 40.4 x 14.2 in on its stand — the stand adds 2.4 in of height and needs a surface 14.2 in deep. On the wall it stands out 2.4 in plus the mount's own profile. Compare it with every other 75-inch body on the above-a-fireplace and TV-cabinet pages.
What that means when you shop
400 x 400 mm sits in the middle of the range most "medium to large" mounts cover — check that the mount's largest pattern is at least 400 wide and 400 tall, because some budget mounts stop at 300 x 300. At 60.2 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' 75-inch TVs: Sony BRAVIA 2 II (61.7 lb, 300 x 300 mm); TCL QM8K (62.6 lb, 400 x 400 mm); TCL QM8L (62.6 lb, 400 x 400 mm). 2 of them share this TV's pattern.
Same mount, different model: LG's 75UA7000PUB (UHD UA7000, 2025) also uses 400 x 400 mm and weighs 60.2 lb; LG's 75UA7100AUB (UHD UA7100, 2025) also uses 400 x 400 mm and weighs 60.2 lb. A mount that suits the 75UA7700AUA suits them too, which is handy if you are choosing between them.
Among LG's 158 models here, 24 use 400 x 400 mm (16%); LG's most common pattern is 300 x 200 mm. It is a 2025 model still listed by LG.
