Custom Home
Maintain meeting room settings without unintended changes
Designed to simplify conference room management, Custom Home allows admins to lock specific meeting room settings, preventing users from changing settings between meetings. Now, conference rooms can work throughout the day as intended, without errors, allowing IT to focus on other tasks.
Tizen Zero Config
Easier setups and updates for reduced workloads
Tizen Zero Config is essential for IT managers operating multiple units in different locations. Following display installation, IT professionals can register new apps through Tizen Business Manager and remotely install, eliminating needless travel and local installations.


Auto Level
Flexible installation for custom designs
Keep content clear and steady. Auto Level automatically adjusts content when the screen is rotated from vertical to horizontal for increased versatility in any space. Plus, it automatically recognizes incorrect pivot directions to keep the display always in the correct orientation.
Eco-conscious technologies
Eco-packaging and industry certification to greenify our world
QBB series uses recycled plastics for the rear side cover and packaging. Additionally, Samsung received certifications for energy savings and carbon footprint reduction and complies with restriction guidelines for hazardous substances such as RoHS, REACH and WEEE.
