Project example: a 75-inch TV hung low on a tall wall in a vaulted great room — what it looks like and what it costs

The scenario

The room is an open great room of the kind found in the larger Corona del Mar homes: a ceiling that rises to a peak, a row of clerestory windows high on one wall, tall glass doors on the other, and one smooth painted wall of drywall, about fifteen feet high, facing a long linen sectional. The seating is far from the wall, and the afternoon sun reaches deep into the room.

The request is a 75-inch TV on the tall wall that does not look lost in it, with the screen at a comfortable height, the picture readable in daylight and no cords showing. A tall wall invites a high screen, and a high screen is hard on the neck, so the position is set from the seats instead of from the wall.

What the job involves

1. The installer sits in the sectional, marks the seated eye line on painter's tape and fixes the center of the screen close to it, which puts the TV much lower on the wall than its height suggests.
2. The same afternoon the sun position is noted on the wall, and a sheet of black paper held at the planned spot shows whether the glass doors reflect into the screen at viewing hours.
3. Studs are found and confirmed, and a tilting mount with a wide plate is lag-bolted into two of them at the planned height with a laser line as reference.
4. The TV, carried by two people from the entry, is hung and locked, then tilted a few degrees so the reflection moves off the seats.
5. An in-wall rated power kit and a CL3-rated HDMI cable are fished down the stud bay to a recessed plate behind the console, which sits across the room.
6. Every input is tested from the sectional and the floor is vacuumed.

Hardware and materials

• Tilting mount rated for 70–85 inch panels, with a plate wide enough to reach two studs
• Laser level, stud finder and painter's tape for the mock-up
• In-wall rated power kit and a CL3-rated HDMI cable long enough for the run
• Fish tape and low-voltage plates for the two openings
• Moving blankets and a second person for the carry

Add-ons often paired with this job

• Mount a soundbar as well — +$65–$100. A soundbar hangs under the screen on its own bracket; in a tall room a bar on the console is often used instead.
• Full-motion (articulating) mount — +$35–$60. A swing arm lets the screen turn out of a stubborn reflection, at the cost of a stronger anchor.
• I need the mount supplied — +$55–$165. A tilting mount sized to a 75-inch set can be supplied when none has been bought.

Why it is done this way

A very tall wall does not change the rule that the screen belongs near the seated eye line. Mounting low and adding a small tilt keeps the neck level, and the empty wall above becomes part of the design instead of a problem. Checking the sun before drilling matters because glare cannot be fixed afterwards without moving the mount.

The long in-wall run is the other half of the job. A rated kit and CL3 cable inside the stud bay leave the wall clean, while a plain cord would be both unsafe and visible. The 75-inch size falls in the 66–85 inch band, so the price comes straight from that range.

What would change the price

• Fire blocking or a window header interrupts the stud bay, so the cable takes a longer path or a painted raceway is used.
• An 86-inch set moves the base to the top size tier.
• The glare check calls for a swing arm instead of a tilting mount, which adds the arm line and a stronger anchor.
• A second visit to see the sun at another hour is rare but adds time to the planning.
• A new outlet behind the console is an electrician's job and is priced separately.
