Think about viewing comfort, glare and traffic flow. Ideally, the TV should face the main seating area so you’re not twisting your neck every time you watch. Sit on your sofa and imagine where your eyes naturally rest – that wall is often a good candidate.
Avoid placing the TV where strong daylight from windows hits it directly, either from behind you (causing screen glare) or behind the TV (creating eye strain). If that can’t be avoided, use curtains or blinds to control light.
Check walking paths too. You don’t want people constantly crossing in front of the screen or bumping into cables. Make sure there’s enough space for a media unit and ventilation around the TV. Mounting it slightly above eye level when seated works for most people; too high and you’ll feel like you’re in the front row of a cinema.
Lastly, think about whether the TV will be the main focal point or one of several elements. Arrange furniture so it fits your real life, not just the ideal Instagram setup.
