TopAV buying advice
Is the SMART GX175G-V4-5A right for your classroom?
For classrooms that want a walk-up-and-teach board without a trolley PC.
Shortlist the GX Plus where a teacher should be able to walk up, sign in and start the lesson from the board itself rather than from a wheeled computer. The embedded Android 14 system carries the Google Play Store, so a school installs the apps it already licenses, and the front USB-C, HDMI and USB-A ports mean a visiting laptop still connects in one move. The panel is rated at 400 cd/m2, which suits a room where blinds or lighting can be controlled rather than a glazed atrium. Check the furthest seat before settling on 75 inches: a long hall or a large upper-school room may read better on the 86-inch model.
Reasons to shortlist it
- The embedded Android 14 system is Google Play Protect Certified and carries the Google Play Store, so a school installs the apps it already licenses and runs lessons without adding an external PC.
- Advanced infrared touch tracks up to 50 touch points, depending on the operating system in use, with a typical touch response of 5 ms or less, 1 mm accuracy and a 2 mm minimum object size, so several pupils can write on the glass at once.
- One front USB-C cable carries 4K at 60Hz video, touch, digital audio and up to 65W of power delivery to a teacher's laptop, and a second USB-C at the rear supplies up to 15W for a camera or other accessory.
- Two integrated 20W speakers, three HDMI 2.1 inputs (one front, two rear) and a rear OPS slot rated at 90W cover lesson audio, several sources and an optional Windows module without extra boxes on the wall.
- We are a SMART Platinum partner, so warranty claims and replacements go through us rather than a queue.
Check before you choose
- 75 inches suits a standard classroom. For a long room, a hall or the back rows of a large upper-school space, compare viewing distances against the 86-inch GX186G-V4 before ordering.
- The box holds the display, two pens, a remote control, Wi-Fi and Bluetooth antennas and cables, not a PC. Budget separately for the mount, installation, any OPS Windows module and a camera. SMART lists no built-in microphone on this series, so video calls need a separate microphone or room system.
- Object Awareness and simultaneous tool differentiation require a connected computer running SMART Product Drivers, and SMART supports them in SMART Notebook and SMART Ink. Confirm with your IT team which machines will carry the drivers, and agree Google account policies and app licences, before rollout.
See the 75" on your wall, to scale
On a phone, point your camera at the wall and see the 75" there at its real size. On a computer, upload a photo of the wall (or scan the QR code to take one with your phone and it will appear here) and drag the display around it to scale.
Not sure 75" is the right size for the room? The screen size calculator shows how far a 75" display carries for presentations, touch work and video.
What to plan before installing the GX175G-V4-5A
01
Size & sightlines
Measure the longest viewing distance and the smallest text pupils need to read, and allow space for them to reach the lower part of the glass.
02
Mount & connections
The 75-inch panel weighs about 52 kg, so check wall construction, mounting height, a 100V to 240V supply and data. Leave room around the display for ventilation, and consider a height-adjustable mount so younger pupils can reach the writing area. SMART lists a 800 x 400 mm (M8) VESA pattern.
03
Software & accounts
Decide whether lessons run on the embedded Android system or a connected laptop, and confirm SMART Notebook, SMART Product Drivers and Google account sign-in with your IT team. Tell us if you need mounting, cabling or a camera.
Display price is for the panel. Installation and optional equipment are quoted separately. Purchase-order terms are available to approved education customers.
Build a quote you can compare
Include these details in your project enquiry so the quote covers the room as well as the screen.
- Number of displays, site postcode and required date.
- Furthest viewing distance and available wall space.
- Wall type, fixed mount or adjustable trolley, and cable routes.
- Laptop model, teaching apps, and any camera or Windows PC needs.
Ask for separate equipment, delivery, installation and licence costs, with a total including VAT. Confirm warranty coverage and any registration requirements before placing the order.

SMART GX175G-V4-5A questions answered
Who is the SMART Board GX075-V4 Plus best suited to?
Consider it for a primary or secondary classroom that wants a board a teacher can use straight away without a separate computer, at a lower cost than SMART's flagship ranges. Check that text is readable from the furthest seat before choosing 75 inches; a larger room may need the 86-inch model.
Does the GX Plus need a computer to work?
No. The Android system is embedded in the display, with a digital whiteboard, web browser, screen sharing, an app library and the Google Play Store, so it runs lessons on its own. A laptop connects over USB-C or HDMI when a teacher wants their own files, and a SMART OPS PC module can be fitted in the rear slot for a fixed Windows machine.
Which version of Android does it run?
Android 14.0, listed by SMART as forward compatible, on an octa-core 64-bit processor with over-the-air updates. Confirm the version installed on your delivery with us if a particular app or management policy depends on it.
Does it include the Google Play Store?
Yes. SMART lists the embedded operating system as Google Play Protect Certified with the Google Play Store, and the order description for this model reads 'interactive display with embedded OS (GMS)', meaning Google Mobile Services are included. That lets a school install and sign in to the Google apps it already uses.
Can I connect a laptop with a single USB-C cable?
Yes. The front USB-C port carries 4K at 60Hz video over DisplayPort alternate mode, touch data, digital audio and up to 65W of power delivery, so one cable connects and charges most laptops. Your laptop and cable must support DisplayPort over USB-C, and a laptop needing more than 65W may still need its own charger. A 1.8 m USB-C cable is supplied.
How many people can use the GX075-V4 Plus at once?
SMART lists up to 50 touch points, depending on the operating system in use, on an advanced infrared touch system. Two pens are supplied with magnetic frame-mounted holders, so several pupils can write and move objects together along the width of a 75-inch panel.
Does it have a built-in microphone or camera?
No. SMART's specification for this series lists two integrated 20W speakers but no microphone and no camera, so a room used for video calls needs a separate microphone, camera or all-in-one bar. The rear USB-C port supplies up to 15W and the USB-A ports can carry a camera you add.
How much memory and storage does it have?
8 GB of DDR4 memory and 64 GB of storage, expandable to 576 GB with a microSD card in the rear slot, as listed on SMART's specification sheet.
What is in the box?
A country-specific power cable, a 5 m USB 2.0 A to B cable, a 1.8 m USB-C cable, two pens, two external Wi-Fi and Bluetooth antennas, a remote control with two AAA batteries, illustrated installation instructions and an important information document. The mount, any OPS module and any camera are ordered separately.
Should I choose the 75-inch GX075-V4 Plus or the 86-inch GX086-V4 Plus?
Choose by viewing distance and the smallest text people need to read, not by room capacity alone. Both share the same 4K resolution, 400 cd/m2 brightness, touch system and ports, so the 86-inch panel adds size rather than detail, and draws more power. Use the screen-size calculator and check the wall space before deciding.
