All three models incorporate advanced LED backlighting technology, contributing to enhanced energy efficiency and longer lifespan. They feature wide viewing angles, ensuring that images maintain their integrity from different perspectives, making interaction seamless in collaborative settings. Hyundai’s commitment to user-friendliness is evident in the inclusion of versatile connectivity options, accommodating HDMI, DisplayPort, and USB interfaces, allowing for simple integration with various devices.

Furthermore, the displays are designed with durability in mind. They come equipped with robust surfaces that are resistant to scratches and impacts, catering to the rigors of public use.
