Optimal TV height in a shallow living room nook aligns the bottom edge of the screen slightly above seated eye level, typically about 42 to 48 inches from the floor depending on seating height. This height ensures comfortable viewing without neck strain. Mounting the TV on a vertical panel within a media wall helps achieve this ergonomic placement. Avoid positioning the TV too high, like above tall mantels, as it leads to discomfort and a poor viewing experience.
