Your lobby screen keeps going blank at 6am Monday, or the menu board is still showing last week's special because the old panel died and the replacement is 'back in three weeks.' This 50-inch Samsung QBC-N was built to run 16 hours a day, seven days a week without drama. 350 nits keeps content readable under fluorescent lighting. Three HDMI 2.0 inputs let you swap sources without hunting for adapters. RJ45 and RS232 are there for the sign controller you already have. Tizen 7.0 handles your playlist. VESA 200×200 mounts to your existing bracket. At 11.8 kg and 28.5 mm deep, it disappears into the wall. Three-year hardware warranty covers the panel
