TCL QM8 QD-Mini LED QM851G 85-inch wall mount: VESA 600 × 500 mm, 102.5 lb
The TCL QM851G 85-inch (85QM851G) uses a VESA 600 × 500 mm pattern and weighs 102.5 lb without its stand. 600 × 500 mm is outside the standard VESA sizes, so it needs a mount that names this spacing or a large-format plate rated above 102.5 lb.

| Weight without stand | 102.5 lb (106 lb with stand) |

See it on AmazonThe QM851G 85-inch against its lineup
TCL lists the 2024 QM851G (QD-Mini LED) in 65, 75, 85 and 98 inches. 4 of the 15 TCL 85-inch models from 2024 to 2026 in this research use 600 × 500 mm; the others use 600 × 400 (9) or 400 × 400 (1). 3 of them weigh more than this one. 102.5 lb is about 11% over the 92 lb typical of 85-inch panels, so read the weight rating before the size range.
What changed from the 2023 TCL QM850G
- Pattern: 600 × 600 mm on the QM850G, 600 × 500 mm on the QM851G. An older bracket fits only if its VESA range also covers 600 × 500 mm.
- Weight: 105.6 lb then, 102.5 lb now (3.1 lb lighter).
- Screws: M8 on both.
- Plan on a new bracket unless the old one's range reaches 600 × 500 mm.

Screws, studs and height
TCL lists M8 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 23.6 in apart side to side, wider than 16-inch stud spacing, so a standard wall plate reaches a stud on each side.
With the center at 42 in for sofa seating, an 85-inch screen runs from about 21 in to 63 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 QM851G

Frequently asked questions
What VESA pattern does the QM851G 85" use?
VESA 600 × 500 mm: 600 mm between the holes side to side and 500 mm top to bottom (23.62 × 19.69 in), with M8 screws. That is from TCL's product page, checked Sep 22, 2026.
How much does the QM851G 85" weigh?
102.5 lb without the stand and 106 lb with it. Bracket ratings are for the panel alone, so 102.5 lb is the number to shop against, and it is a two-person lift.
Will a mount from the 2023 QM850G 85" fit?
Only if its VESA range covers 600 × 500 mm: the QM850G used 600 × 600 mm.
Can the QM851G 85" hang on drywall without studs?
No. Drywall alone is for TVs up to about 32 in and 30 lb on rated toggle anchors. At 85 in and 102.5 lb it needs the bolts in studs, or masonry anchors in brick or concrete.
Want the QM851G mounted for you?
Mounting an 85-inch TV is $299 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.
