LG Gallery TV LX7B 55-inch wall mount: VESA 400 × 300 mm, 41 lb
The LG LX7B 55-inch (55LX7BPUA) uses a VESA 400 × 300 mm pattern and weighs 41 lb without its stand. Any mount that lists 400 × 300 mm, is rated above 41 lb and covers 55-inch screens fits it. LG includes its flush wall mount with it and also lists the 400 × 300 mm holes.
| VESA pattern | 400 × 300 mm (15.75 × 11.81 in) |
|---|---|
| Weight without stand | 41 lb (43 lb with stand) |
| Screws | M6 |
| US model number | 55LX7BPUA |
| Maker's mount | LG flush wall mount (in the box) |
| Model year | 2026, QNED Mini LED LCD |
VESA and weight from LG's product page, checked Sep 23, 2026. Measure your own TV's holes if the model number on its sticker differs.
The LX7B comes with its own mount
LG puts its flush wall mount in the box. A flush mount leaves no room behind the TV for a power strip or a loop of cable, so the part most installs still need is an in-wall power and cable kit.
Power and HDMI run inside the wall
Legrand
For the flush install: power and HDMI through the wall.
Legrand's UL-listed power bridge is the code-correct way to get an outlet behind the TV without running an extension cord inside the wall.

See it on AmazonThe LX7B 55-inch against its lineup
LG lists the 2026 LX7B (QNED Mini LED LCD) in 55 and 65 inches. 1 of the 27 LG 55-inch models from 2024 to 2026 in this research use 400 × 300 mm; the others use 300 × 200 (22) or 300 × 300 (4). This is the heaviest of them. 41 lb is about 24% over the 33 lb typical of 55-inch panels, so read the weight rating before the size range.
Screws, studs and height
LG lists M6 screws for the four holes. Use the screws that match that thread from the bracket's kit, and stop if one bottoms out before the plate is tight: a spacer fixes that, force does not.
The holes are 15.7 in apart side to side, close to 16-inch stud spacing, so the mount's arms and the studs line up easily.
With the center at 42 in for sofa seating, a 55-inch screen runs from about 29 in to 55 in off the floor. In a bedroom the center goes 42 to 50 in. The height calculator works it out for your own seat.
Other sizes of the LX7B
The LX7B changes pattern with size: 55" 400 × 300, 65" 400 × 400. Buy for the size you own.
| Size | VESA | Weight without stand |

Frequently asked questions
What VESA pattern does the LX7B 55" use?
VESA 400 × 300 mm: 400 mm between the holes side to side and 300 mm top to bottom (15.75 × 11.81 in), with M6 screws. That is from LG's product page, checked Sep 23, 2026.
How much does the LX7B 55" weigh?
41 lb without the stand and 43 lb with it. Bracket ratings are for the panel alone, so 41 lb is the number to shop against.
Does the LX7B come with a wall mount?
Yes. LG lists its flush wall mount in the box. The 400 × 300 mm VESA holes are listed as well, which is what a tilting or full-motion bracket would use.
Can the LX7B 55" hang on drywall without studs?
No. Drywall alone is for TVs up to about 32 in and 30 lb on rated toggle anchors. At 55 in and 41 lb it needs the bolts in studs, or masonry anchors in brick or concrete.
Want the LX7B mounted for you?
Mounting a 55-inch TV is $159 flat in all 13 metros we serve. The bracket is separate: bring your own, or add a flat mount for $69 or a full-motion mount for $79. Every install carries our 3-year workmanship warranty.
