Core Highlights & Key Features

• 8-Core Performance Unleashed: Power through data-heavy educational videos and intensive application multitasking with a cutting-edge 8nm process chip. This architecture features an 8-Core CPU (A76x4 + A55x4 at 2.4GHz) and a dedicated 6 TOPS NPU. It delivers 6X the performance of standard quad-core chips to amplify speed and productivity.

• Colossal Memory & Storage Capacity: Maintain glass-smooth performance while executing screen recordings, hybrid teaching streams, and digital course navigation all at once with a robust 16GB of ultra-large RAM. Paired with 256GB of local storage (expandable up to 1TB), it easily holds up to 60,000 lecture slides or 400 hours of educational video.

• Stunning 86" Visual Precision: The massive 86-inch panel brings content to life using a 98% sRGB wide color gamut and 1.07 billion colors (10-bit). Production-level manual calibration yields a pro-grade color accuracy of $\Delta E < 1$. Combined with 500 nits maximum brightness, your presentations remain brilliantly sharp and legible from the back of the room.

• Advanced DC Dimming Eye Protection: Protect your audience's eyes during prolonged presentations. Moving away from traditional PWM dimming screens that use rapid on/off light cycles, the U8640 uses DC Dimming to adjust brightness directly, entirely eliminating screen flicker. It is fully certified by TÜV for Flicker-Free and Low Blue Light performance.

• 50MP Ultra-HD AI Camera: Capturing the entire room effortlessly, the built-in 50MP camera utilizes a 115° wide-angle lens (115° DFOV). It comes fully optimized with AI features including Auto Framing, Speaker Tracking, Person Counting, and Random Selection.

• SkyWave Sound System: Fill deep room environments with exceptional audio clarity through a 2.2 channel setup powered by four integrated speakers (up to 2x12W + 2x25W maximum power). The onboard 8-microphone array features a 180° pick-up angle and an impressive 0-12m reach, supercharged by AI Spatial Sound, Auto Echo Cancellation (AEC), and an Intelligent Audio Fence.

• MAXHUB Think & Ink Technology: Brainstorm effortlessly on a premium 9H scratch-resistant glass surface engineered to reduce friction by 40%. The infrared touch matrix logs up to 50 touch points with an industry-leading ±0.5mm accuracy and a 2.5ms response time. It natively supports Perceptive Palm Rejection, Direct Annotation, Sharp Erase, and pressure sensing.
