75" Multi-touch Interactive UHD LED 400 nits

The Vivitek NovoTouch BK752i is a 75-inch interactive flat panel built around 4K Ultra-HD resolution and responsive multi-touch operation. Its Backlit D-LED panel uses IPS-ADS technology and pairs a 3840 × 2160 image with Android™ 13, NovoConnect Wireless Collaboration, a digital whiteboard, and built-in digital signage. These integrated capabilities support shared presentations, interactive instruction, and managed visual communication from one display.

Ideal Use Cases

The BK752i is designed for educational and business environments where participants need to view, present, and annotate content together. In classrooms and training rooms, instructors can use the digital whiteboard and multi-touch surface for interactive lessons. Conference rooms can use NovoConnect for easy wireless screen sharing during meetings, reviews, and presentations. The built-in digital signage solution also allows the panel to serve as a communication display when it is not being used for an interactive session.

Why Choose This Model

A combination of screen size, touch flexibility, and onboard collaboration tools distinguishes the BK752i. Infrared touch supports up to 20 finger-touch points, while annotation supports 10 points. The panel works with fingers, styluses, gloves, and opaque objects, giving users several ways to interact without relying on one input method. Touch resolution is 32,768 × 32,768, and specified accuracy for a finger or passive pen is ±2.0 mm across more than 90% of the area.

The interactive surface is protected by 3 mm toughened glass rated at Level 7H on the Mohs hardness scale. This protection is paired with two included styluses, making the panel ready for writing and annotation sessions.

Installation and Integration

The BK752i is intended for landscape installation and supports an 800 × 400 mm VESA mounting pattern using four M8 × 25 mm mounting points. A wall mount kit is included. Power compatibility is AC 100–240V at 50/60Hz, with a specified 4.5A rating.

Connection options include four HDMI inputs, one HDMI output, HDMI 2.0, four USB-A 3.0 ports, two USB-B ports, and one USB-C 3.1 port with 15W power. Two RJ45 LAN ports and Wi-Fi 6 provide wired and wireless networking options. Additional integration connections include RS232 input, SPDIF output, and 3.5 mm audio input and output. The supplied Wi-Fi 6 USB module, HDMI cable, USB cable, audio cable, AC power cord, remote controller, and documentation kit help support initial setup.

Performance Highlights

The 75-inch panel presents content at a native 4K Ultra-HD resolution of 3840 × 2160 with a 60 Hz refresh rate. A specified 178-degree horizontal and vertical viewing angle supports visibility from a broad range of positions. The display produces 1.07 billion colors and has an estimated lifetime of 50,000 hours. Its stated daily operating schedule is 16 hours per day, seven days per week.

Android 13 and 32GB of eMMC storage provide the onboard platform and storage capacity for the panel’s integrated functions. The silver finish and large-format design suit permanent installations in instructional, meeting, and presentation spaces.

What Makes It Different

The BK752i combines three functions that are often central to shared spaces: wireless collaboration, interactive whiteboarding, and digital signage. NovoConnect simplifies screen sharing, while the multi-touch layer enables direct participation at the display. When an interactive session is not required, the built-in signage solution provides another use for the same installed panel.

Its extensive physical connectivity also supports a variety of source and control arrangements. Multiple HDMI inputs accommodate several connected sources, HDMI output expands routing options, and the selection of USB, network, audio, and control ports provides flexibility for room integration.

Final Assessment

The Vivitek BK752i is a strong match for organizations seeking a 75-inch 4K interactive display with 20-point finger touch, Android 13, Wi-Fi 6, and integrated collaboration tools. Its combination of toughened glass, broad connectivity, included mounting hardware, and a 50,000-hour estimated display lifetime makes it suited to recurring classroom, meeting-room, and signage use. Standard panel warranty coverage is three years; registered education installations receive five-year panel coverage, with accessories excluded in both cases.
