Mount checklist for the 86UA7700PUA
- 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: 74.1 lb without the stand. Mounts are rated by maximum load; a mount rated 80 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: 75.6 x 43.4 x 2.4 in
LG lists the 86UA7700PUA at 75.6 in wide, 43.4 in tall and 2.4 in deep without its stand (192 x 110 cm), and 75.6 x 46.5 x 16.3 in on its stand — the stand adds 3.1 in of height and needs a surface 16.3 in deep. On the wall it stands out 2.4 in plus the mount's own profile. Compare it with every other 86-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 74.1 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.
Same mount, different model: LG's 86UA7500ZUA (UHD UA75, 2025) also uses 400 x 400 mm and weighs 74.1 lb. A mount that suits the 86UA7700PUA suits it 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.
