A:Answer Since the U7900 doesn’t have an outdoor‐use rating, it likely lacks the rugged design, sealed enclosure, and weather‐proofing that outdoor-specific TVs have.
If you mount it outside, you risk exposure to moisture, dust, heat, direct sunlight, humidity, and temperature swings which could lead to shortened lifespan, display problems, or failure.
For a patio, backyard, or fully exposed outdoor area, the safer route is to use a TV specifically built for outdoor use, like Samsung The Terrace.
