85" LG OLED TV installed on a full-motion bracket above a floor-to-ceiling white quartz fireplace — stud location verified by calculation and endoscope in a luxury Cary home.
This Cary home features a dramatic floor-to-ceiling white quartz fireplace wall — one of the most striking architectural elements in the room. The homeowner wanted an 85" LG OLED TV mounted above the linear fireplace on a full-motion bracket, giving full flexibility to adjust the viewing angle from different positions in the open-plan living space.
The quartz surface is visually seamless — no visible seams, no exposed framing. Clean, modern, and completely unforgiving of mistakes. A full-motion mount carrying an 85" display puts significant dynamic load on the wall anchor points, which means structural framing is not optional — it's the only way to do this safely.
Standard stud finders don't work through quartz. The stone surface and its backing material interfere with the magnetic and electronic sensors in conventional stud finders, producing unreliable or completely false readings. Attempting to drill based on those readings would mean either missing the framing entirely or hitting it off-center — neither acceptable on a surface like this.
Full-motion load requirements. A fixed mount distributes weight vertically. A full-motion arm extends the TV outward from the wall, creating leverage that multiplies the effective load on the anchor points. With an 85" panel, that load needs to go directly into structural framing — no exceptions.
We located the framing using a combination of precise mathematical calculation and endoscope inspection. By measuring from known reference points — corners, seams, structural features — and cross-referencing with standard framing intervals, we calculated the probable stud locations before touching the wall. The endoscope confirmed the exact position.
The result: we drilled on the first attempt, hit the framing dead center, and the mount anchors seated perfectly in solid structural wood. No exploratory holes, no adjustments, no damage to the quartz surface.
The 85" LG OLED sits centered on the quartz wall, perfectly level, with the full-motion arm fully operational. The bracket extends and retracts smoothly, holds position at any angle, and carries the panel's weight without any flex or movement in the mount itself. The quartz surface is intact — the only visible evidence of the installation is the TV and its mount, exactly as intended.
The finished space is exactly what the homeowner envisioned: a large-format display integrated into a luxury fireplace wall, with the flexibility to watch comfortably from anywhere in the room.
