There is no useful single TV height for every sofa, screen and room. A measurement that works in one living room can feel awkward in another. The best starting point is the seat you use most.
Test an outline before choosing holes
Sit naturally with the cushions and posture you normally use. Have someone mark an approximate screen outline with removable tape while you stay seated. Watch where your gaze falls and whether you feel the need to hold your head in an unusual position.
Repeat the check from other important seats. In a shared room, aim for a practical compromise rather than optimizing the view from the doorway. A photo from each seat can help communicate the issue when asking for advice.
Include the furniture and soundbar
Work the console, shelves and soundbar into the outline. Leave enough room for their intended use and required clearances, rather than pushing the TV upward just to create a perfectly symmetrical wall. Check whether decorative objects would block part of the screen.
Samsung’s wall-mounting guidance discusses seated eye level and furniture placement. Treat any example dimension as a starting reference, not a replacement for testing your own room.
Check daytime and nighttime use
Look at the proposed position with window coverings open and with evening lights on. Glare can change which wall works best. Moving a screen higher is not always the most effective answer; the seating arrangement, light placement or mount angle may deserve attention.
For an above-fireplace installation, evaluate comfort alongside the fireplace and TV requirements. If those constraints make the position unsuitable, a nearby wall can be a better solution. Bring the approximate screen outline and your concerns to the installation conversation before the final mounting points are chosen.
