75MR61DE-E

What the 75MR61DE-E is built to do

The 75MR61DE-E brings a large touch display, an Android 13 computer and an electronic whiteboard into one 75-inch unit, so a room does not need a separate PC, projector, screen and whiteboard. Its 3840 x 2160 panel has four times the pixel count of Full HD, which keeps small text and fine diagrams readable from the back of a classroom or boardroom.

Panel, touch and eye comfort

The D-LED backlit panel is rated at 400 nits, with a 1,200:1 typical contrast ratio, an 8 ms response time and a 60Hz refresh rate. Viewing angles reach 178 degrees horizontally and vertically, and the panel displays 1.07 billion colours using 10-bit processing across a stated 72% colour gamut. An ambient light sensor adjusts brightness to the room, and the anti-glare glass reduces reflections. The unit carries Energy Star certification and a TÜV Rheinland certification for reduced blue light, and its listed panel lifetime is 50,000 hours.

The infrared touch frame supports up to 20 touch points with 90% accuracy (±1 mm) and detects objects from 2 mm. The stated writing height is under 1.5 mm, so pen strokes start close to the glass. Teachers can write with a pen tip, erase with the pen cap, move objects with a finger and clear areas with the palm.

Android 13, connectivity and expansion

The system runs Android 13 on an ARM processor with four A73 cores at 2.2GHz and four A53 cores at 2.0GHz, with a Mali-G52 graphics processor, 8GB RAM and 128GB storage. The display carries Google Certification, and Google Education apps such as Classroom, Chrome, Drive, Docs and Gmail can be used for lessons and staff work. Wireless options include 802.11 a/b/g/n/ac/ax Wi-Fi, Bluetooth 5.1, NFC, Miracast, DLNA and Webcast, and dual Wi-Fi modules allow a screen-sharing hotspot and a network connection at the same time.

Inputs include three HDMI 2.0 ports, a Type-C port that supports 65W power delivery, three USB 3.0 ports, a LAN port, touch and audio inputs and an RS-232 input. Outputs cover HDMI, S/PDIF, audio and two RS-232 ports. An optional OPS slot takes a plug-in computer module with its own DC 12V/5A supply. The unit has no built-in camera, so video calls need an external camera or a conferencing device. Its built-in speakers are rated 2x15W+20W and the audio supports Dolby Atmos.

Where it fits across Qatar

• A classroom in Al Wakrah or Education City: teachers run lessons from Google Classroom, annotate slides on the glass and share content from tablets through wireless screen sharing.
• A boardroom in West Bay: the screen shows shared documents clearly to a group around a conference table during calls with teams abroad, once an external camera and microphone are added.
• A training room in the Industrial Area or Mesaieed: site inductions and operator briefings use the whiteboard tools, and the 350W maximum draw without OPS should be checked against the circuit serving the room.

Planning the installation

The panel measures 1709.9 x 1024.4 x 118.2 mm and weighs 45.5 kg net or 59.7 kg packed. Its VESA pattern is 600 x 600 mm with four M8 screws, and a wall mount bracket is included. A mobile cart is available as an optional accessory for rooms where a wall cannot carry the load. Because of the weight, a free site survey from SmartRooms Qatar can check wall structure, mounting height and power point position before installation day.

The source data does not give an operating temperature range, so ask the SmartRooms Qatar team to confirm room conditions before mounting near windows or in spaces without air conditioning. The language list in the data does not include Arabic, so confirm the interface languages you need before ordering.
