Corner TV Mount Planning Checklist

Use this checklist before ordering a corner TV mount. It catches the problems that product photos tend to hide.

1. Draw the top view

Sketch both walls, the corner, the TV width, and the wall plate. Add the screen in its viewing position. This quickly shows whether the television will hit the adjacent wall before it reaches the desired angle.

2. Verify extension and swivel together

More swivel usually requires more extension. Compare the mount's dimensions with the actual TV width. A published angle is not useful if the screen cabinet collides first.

3. Confirm the structural wall

The mount generally attaches to one wall. Identify its framing and verify a load path for the display plus the extended arm. Peerless-AV recommends evaluating the structure for both the display and mount weight.^[1]

4. Place the center for the viewing position

Judge height and angle with the TV swung into normal use, not folded against the wall. THX's viewing guidance keeps the screen center close to the seated sightline.^[2]

5. Leave a controlled cable loop

Power, HDMI, and soundbar cables need enough slack for the complete motion without hanging below the screen or becoming pinched. Move the mount slowly during the final test and watch every cable.

Before ordering hardware

Record the exact TV model, cabinet width, weight, VESA pattern, and connection locations. Measure both walls from the corner to any window trim, outlet, shelf, or doorway. Note the seating position and desired screen-center height. Then compare those measurements with the mount's wall-plate width, folded depth, extension, and rated swivel. This is faster and cheaper than discovering after installation that the screen edge hits the wall or the HDMI plugs face the wrong direction. Photograph the measurements for later reference.

If the drawing cannot produce a clear motion path, use a different wall or a floor stand rather than forcing the corner.
