Mount checklist for the OLED77B5PUA
- 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: 50.5 lb without the stand. Mounts are rated by maximum load; a mount rated 60 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: 67.7 x 38.9 x 2 in
LG lists the OLED77B5PUA at 67.7 in wide, 38.9 in tall and 2 in deep without its stand (172 x 99 cm), and 67.7 x 41.6 x 12.6 in on its stand — the stand adds 2.7 in of height and needs a surface 12.6 in deep. On the wall it stands out 2 in plus the mount's own profile. Compare it with every other 77-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 50.5 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' 77-inch TVs: Sony BRAVIA 6 OLED (55.3 lb, 400 x 300 mm); Samsung OLED S85H (62 lb, 400 x 300 mm); Samsung OLED S95H (69.9 lb, 400 x 400 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 OLED77B6GUA (OLED B6, 2026) also uses 300 x 200 mm and weighs 50.5 lb; LG's OLED77C3AUA (OLED evo C3) also uses 300 x 200 mm and weighs 51.8 lb; LG's OLED77C5PUA (OLED evo C5, 2025) also uses 300 x 200 mm and weighs 51.8 lb; LG's OLED77C6HUA (OLED evo C6, 2026) also uses 300 x 200 mm and weighs 51.8 lb. A mount that suits the OLED77B5PUA suits them too, which is handy if you are choosing between them.
Among LG's 158 models here, 56 use 300 x 200 mm (37%), the most common LG pattern. It is a 2025 model still listed by LG.
Other sizes in the LG OLED B5 line
The pattern is not the same across the line: it changes from 300 x 200 mm on the 77" to 400 x 400 mm on the 83". A mount bought for one size is not automatically right for another.

Where to sit
A 77-inch 16:9 screen is 67.1 in wide and 37.8 in tall. It fills the SMPTE 30° view from 10 ft 5 in and THX's 40° cinema view from 7 ft 8 in. At this size 4K looks sharper than 1080p only from 10 ft or closer; beyond that, 20/20 eyes cannot tell the two apart. The 77-inch size page has the full table and every model at this size.
