What the ST7502S is built to do

The BenQ ST7502S is a 75-inch display with a 3840 × 2160 UHD panel, made for signage, announcements and lesson content on campus. It runs its own Android 8.0 system, so much of the content can play without a separate media player. The landscape panel uses 8-bit colour depth and a 72% NTSC colour gamut, and it is rated for 18 hours of operation per day, seven days a week.

Connections for classrooms and offices

Three HDMI 2.0 inputs let you link laptops, document cameras or media players. The panel also offers VGA, two USB-A 2.0 ports, a micro SD reader, a PC audio input, an earphone output and a 10/100 Mbps Ethernet port for the Android system. One RS-232 port with an input and an output allows control integration. The display has no HDMI output, so it cannot pass its picture to a second screen. It is also a non-touch model, which suits viewing, presentations and signage rather than hands-on writing.

Running a PC and sharing screens

A single OPS slot accepts a slot-in PC, so Windows applications can run on the display without an extra notebook or tablet. Wireless screen sharing runs through the InstaShare 1 app from the BenQ App Store, while X-Sign Broadcast and DMS device management handle content and alerts across a site. The panel has no built-in Wi-Fi or Bluetooth, so settle the network design before installation.

Where it fits in Qatar

Lecture rooms in Education City: a 75-inch screen suits a large room where students sit well back from the front. The built-in 2 × 10 W speakers serve small teaching spaces, while larger halls may still need external audio.
Campus corridors in Al Sadd or Msheireb: a looping playlist from a USB stick or micro SD card can show timetables, exam dates and event posters, and X-Sign Broadcast can push an urgent notice to screens across the building.
Reception areas in West Bay or The Pearl: an air-conditioned lobby suits advertising, wayfinding and visitor information. With 400 nits typical brightness, the panel works best where lighting is controlled.

What to plan before installation

The product weighs 35.9 kg and ships at 46.1 kg, with dimensions of 1683.5 × 961.7 × 82.9 mm. It mounts to a VESA 600 × 400 mm pattern with four M8 screws, but no wall mount is included, so the wall or structure and the bracket must carry the load. Its operating range is 0°C to 40°C, well below outdoor summer heat in Qatar, so install it indoors in air-conditioned space away from direct sun. Power is AC 100-240V at 50/60Hz, with typical consumption of 177 W and standby below 0.5 W. ENERGY STAR is listed for this model. A free site survey from SmartRooms Qatar can confirm wall type, cable routes and power points before the units arrive.

Questions about ST7502S

Who is the BenQ ST7502S designed for in Qatar?

It suits schools, universities and corporate offices in Qatar that want a large 4K screen for signage, announcements or lessons. A university in Education City could place one in a busy corridor to show timetables and event updates, then use the same panel in a teaching space. Its Android system and HDMI inputs let it serve both roles without a separate media player.

How does the 75-inch model compare with other sizes in the ST02S series?

The ST02S series is offered in 43, 55, 65, 75 and 86 inches, and the ST7502S sits in the upper part of that range. A 75-inch panel suits a large classroom or lecture room where students sit several rows back, while a smaller size may suit a compact meeting room. Measure the viewing distance and wall width before choosing, and ask our team if you want to compare a sibling size.

Can the ST7502S run all day in a campus lobby?

It is rated for 18 hours of operation per day, seven days a week, so it should not run around the clock. A campus lobby or a West Bay reception area that opens early and closes late should schedule power-off periods in its content plan. Confirm your daily hours with the SmartRooms Qatar team during the quotation so the operating rating matches your schedule.

Does the ST7502S have a touchscreen?

No. The panel lists no touch technology, no touch points and no pen tray, so it is a display for viewing rather than hands-on work. It suits signage, lessons delivered from a connected laptop and presentations. If your classroom needs writing or touch interaction on the screen, ask SmartRooms Qatar for a quote on an interactive display instead.

How do staff play content from a USB stick without a media player?

Plug a USB stick into one of the two USB-A 2.0 ports, and the built-in media player can loop the multimedia files stored on it. A micro SD card reader is also fitted. A facilities team in Msheireb updating a lobby loop each week can swap files on a stick rather than maintain a separate PC. Check the file formats your content team uses before the first install.

Can I run Windows applications on the ST7502S?

Yes, through its single OPS slot. A slot-in PC fitted into that slot lets you run Windows applications on the display without an extra notebook or tablet. BenQ lists the TEY21-i7 OPS slot-in PC as a related product, so confirm the exact model and compatibility with SmartRooms Qatar before ordering. The slot-in PC is not listed as included with the display.

What do I connect to show a laptop presentation in a meeting room?

Use one of the three HDMI 2.0 inputs for the laptop, and the PC audio line-in to carry sound. The panel also has a VGA input and two USB-A ports for peripherals. It has no HDMI output, so it cannot feed a second screen. Plan cable routes to the input ports during the site survey, particularly where a boardroom table sits far from the wall.

Is it suitable for a sunlit lobby or hall in Qatar's summer?

Not without climate control. The operating temperature is 0°C to 40°C, and storage ranges from -20°C to 60°C. Summer temperatures in Qatar often exceed 45°C, and a government service hall in Al Khor with windows facing the afternoon sun can get much hotter. Install the ST7502S indoors in air-conditioned rooms, away from direct sunlight and dust-prone entrances, and confirm the room conditions during the survey.

How heavy is it, and what must a wall mount support?

The product weighs 35.9 kg, and the shipping weight is 46.1 kg. It mounts to a VESA 600 × 400 mm pattern using four M8 screws, and no wall mount is included. Check that the wall or structure can carry the load, and plan for at least two people to lift the panel. A rolling stand can move it between rooms, but confirm the stand's load rating against the 35.9 kg weight first.

What power supply and energy rating does it need?

It accepts AC 100-240V at 50/60Hz, which covers Qatar's 240 V, 50 Hz supply. Typical power consumption is 177 W, and standby draw is below 0.5 W. ENERGY STAR is listed for this model, which helps facilities teams track running costs. Ask your electrician to confirm the outlet and socket type at each mounting point before installation.

Can a school order several units for its classrooms under an LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and quotations are usually issued within one working day. For a school fitting out several classrooms with 75-inch units, send the room list, mounting heights and quantities so the quotation covers each room. Payment can be made by bank transfer, cheque or purchase order, and delivery covers all 8 municipalities of Qatar.
