MAXHUB Education U4 Series U8640 86" Interactive Touch Display

MAXHUB U4 Series

Unleash Learning, Redefined Possibilities.

Brilliant Hues, Healthy Eyes

Experience the difference between ordinary screens and truly exceptional displays. We redefine comfort and clarity with a 98% sRGB wide color gamut and 1.07 billion colors(10-bit). A Delta E of less than 1 and meticulous hardware calibration ensure stunning precision and minimize eye strain, transforming how you see and interact with digital content.

Clarity That Shines in Every Classroom

The MAXHUB U4 Series redefines visibility in bright environments with its advanced Non-Glare Screen technology, minimizing reflections for optimal clarity. With 500 nits peak brightness, it delivers vivid details and an immersive viewing experience, even in sunlit classrooms, ensuring comfort and engagement anytime, anywhere.

Unleashing Advanced Eye Care Solution

Prioritize eye health without compromising visual brilliance. Our displays feature hardware-level low blue light technology, TÜV-certified for superior eye protection. Combined with flicker-free DC dimming, you can enjoy long hours of comfortable viewing without the strain and fatigue associated with traditional screens. Learn more, see more, and protect your vision.

Outsmart Blue Light

Low Blue Light - Engineered for eye comfort, this display takes a multi-faced approach to reducing eye strain. TÜV-certified for low blue light, it effectively filters harmful blue light (400-450nm). The ultra-low blue light irradiance ratio of 11.25% further minimizes eye strain.

DC Dimming Technology

Flicker-Free, Future-Proof - Tired of flickering screens causing eye strain and headaches? Unlike PWM dimming, which uses rapid on/off cycles, DC dimming adjusts brightness directly, eliminating flicker and reducing eye strain. TÜV Flicker-Free certified for superior performance.

Auto Framing

By leveraging auto-framing, the display adapts to the number of participants and their location, delivering an optimal angle for a face-to-face interaction experience.

Speaker Tracking

Speaker-tracking technology locates the sound source in real time, ensuring the speaker is always the center of attention.

Facial Recognition

Make every classroom session more engaging and efficient with smart facial recognition. The camera captures the classroom in real-time, identifies students, calculates attendance, and even randomly selects participants to add an element of surprise and fun to lessons. Whether it’s tracking attendance, answering questions, or participating in interactive activities, this feature keeps students attentive while simplifying classroom management for teachers.

BYOD

With BYOD (Bring-Your-Own-Device), you can seamlessly connect your personal device to the display using a Wireless Dongle, MAXHUB Connect software, or a USB-C cable. Leverage the display’s advanced camera, microphone, and speakers for an unparalleled collaboration experience.

AI Spatial Sound

Our system dynamically adapts to your space, providing optimal EQ modes to customize sound isolation angles, ensuring unparalleled audio quality. Guarantee clear communication for remote participants, free from external distractions.

Automatic Gain Control

Automatic Gain Control (AGC) ensures there’s no need to adjust the volume during meetings — the system does it for you. Everyone’s voice is heard perfectly, making communication effortless.

Auto Echo Cancellation

Echo cancellation eliminates reflected sounds—even in enclosed spaces—ensuring your voice always comes through crisp and clear. Every word stays distinct, making conversations flow smoothly and naturally.

AI Noise Reduction

With 8 array microphones spanning a 180° and boasting an 12-meter voice pickup range, coupled with its AI Noise Cancellation technology, the MAXHUB U4 Series ensures crystal-clear voice transmission for all participants.

Audio Fence

Where clarity meets intelligence. Adaptive EQ modes and AI noise cancellation craft a virtual sound barrier, filtering out external distractions. Experience conversations where every word matters—free from the disruptions of the outside world.

Unleashing Touch Innovation

Revolutionize your brainstorming sessions with MAXHUB Think & Ink, the ultimate "pick up and write" technology. Designed for seamless idea capture, it distinguishes between pen tip, pen tail, finger, and palm with precision, supports 50 touch points, and delivers an industry-leading ±0.5mm touch accuracy. Combined with a re-engineered glass surface that reduces friction by 40%, every touch and stroke feels smoother than ever—empowering teams to collaborate effortlessly and elevate meeting productivity.
