In Samsung's naming, "QB" marks the business-hours tier of its 4K signage. The QBR, QBB and the current QBC models all share the same idea: 4K panels at around 350 nits, rated for about 16 hours a day. They run Samsung's Tizen platform, so content plays without an external PC. Sizes typically run from 43 inches up to 85 inches, depending on the generation.
These are the screens to choose for meeting rooms, classrooms, staff areas, waiting rooms and restaurant menu boards. In these spaces, the lighting is under control and the display is off at night. Paying for 24/7 or high-brightness models in these places adds cost without a visible benefit. If you already have QB screens, Transit can match the model and mount when you expand. If not, we will point you to the current QBC. We handle supply, installation, screen sharing or content setup, and support. See our indoor display solutions page or the Samsung 4K UHD signage range. Contact Transit and we will check availability and send a quote.
