The Optoma 3753RK is a 75-inch 4K UHD interactive flat panel designed for education, business, and collaborative environments. Part of Optoma’s Creative Touch 3 Series, it blends high-resolution visuals with responsive touch technology, smart connectivity, and user-friendly software.

At its core, the 3753RK features a 75-inch LED display with a resolution of 3840 × 2160 (4K UHD). The panel delivers sharp, detailed images with a brightness level of around 450 nits, a 5,000:1 contrast ratio, and a wide 178° viewing angle, ensuring content remains clear and visible even in brightly lit classrooms or meeting spaces. The screen also incorporates anti-glare and anti-fingerprint coatings, reducing reflections and smudges, which is especially valuable in high-traffic collaborative settings.

Touch performance is one of its strongest aspects. The 3753RK supports up to 40 simultaneous touch points on Android and up to 50 touch points on Windows, enabling multiple users to interact at once. It offers sub-millimeter accuracy and a fast response time under 3.3 ms, making writing and drawing smooth and natural. The display includes two pens out of the box and supports both finger and stylus input. Thanks to zero bonding technology, the air gap between the glass and LCD is minimized, improving touch precision and reducing parallax.

In terms of computing power, the display runs on Android 14, with 8 GB RAM and 64 GB storage (specs may vary by region). This makes it capable of running built-in apps such as a whiteboard, file manager, and wireless sharing tools. Being Google EDLA certified, it integrates seamlessly with Google services, ensuring access to apps, updates, and security features. Users can also connect external devices like laptops, tablets, or PCs for more advanced workflows.

Connectivity is a highlight of this model. The 3753RK offers multiple HDMI 2.0 ports, DisplayPort, VGA, and USB-C (with support for video, touch, and data). It also includes several USB-A and USB-B ports, RJ-45 for networking, and RS-232 for control. Wireless options include WiFi 6 and Bluetooth 5.2 (depending on configuration), enabling screen sharing and device collaboration without cables. Audio is delivered through dual 20-watt built-in speakers, suitable for classrooms and meeting rooms without the need for external speakers in most cases.

Physically, the panel measures about 67 × 40 × 4.3 inches and weighs around 45 kg (99 lbs). It is compatible with standard VESA 800 × 400 mm mounts, making installation straightforward on walls or mobile stands. Power consumption peaks at roughly 400 W, with efficient standby power draw below 0.5 W.

Overall, the Optoma 3753RK is built for collaboration. Its large 4K display, responsive multi-touch performance, robust connectivity, and integrated software make it well-suited for classrooms, training centers, boardrooms, and hybrid learning environments. By combining premium touch interaction with flexible connectivity, it helps users present, annotate, brainstorm, and share ideas seamlessly.
