You need a screen that reads clearly from the back of a waiting room, runs your wayfinding content overnight, and doesn't need a tech call every time someone changes the playlist. This 55-inch Samsung QBC-N does exactly that. 350 nits under fluorescent lighting. 8 ms response keeps motion graphics smooth on a departure board or product demo. Three HDMI 2.0 ports, RJ45, and RS232 plug into the sign controller you already run. Tizen 7.0 with 8 GB flash handles scheduling without a separate PC. Even 11.5 mm bezel means no awkward gaps in a video wall. VESA 200×200 drops onto your existing bracket. 15.7 kg, 28.5 mm deep. Three-year hardware warranty on the panel
