A 75-inch 4K panel for shared work

The Sharp PN-LB753 gives a room a 75-inch screen at 3840 x 2160 resolution, using an IPS panel with direct LED backlighting. Brightness is rated at 500 cd/m² and the typical contrast ratio is 1500:1, while 178-degree horizontal and vertical viewing angles keep slides readable for people seated at the sides of a long table. The 60 Hz refresh rate and 8 ms typical grey-to-grey response suit presentations, video calls and everyday interactive use.

The 3.2 mm tempered glass has an anti-glare coating and is zero-bonded with a gap under 1 mm, which reduces reflections from windows and ceiling lights. The glass is rated 9 H for hardness. The panel measures 1,708 x 987 x 87 mm, so check the wall space against those dimensions before ordering.

Touch, writing and sharing from one screen

Infrared touch supports up to 40 touch points, accepts finger, gloved hand and stylus input, and rejects a resting palm. Two passive pens are supplied with 2.6 mm and 6.8 mm tips, so one presenter can write fine notes while a colleague uses a broader stroke. Windows Ink support, a built-in whiteboard and annotation overlay mode let teams mark up slides and documents from any connected source.

EShare lets people share content wirelessly from their own devices. A single USB-C cable can carry video, touch data and up to 100 W of power to a laptop, which keeps the table clear of cables.

Where it fits across Qatar

Boardrooms in West Bay or Msheireb: a ministry or corporate team can present from the built-in apps and whiteboard, reducing dependence on a separate PC for routine meetings.
Classrooms in Al Wakrah or Education City: the Google Play Store, PDF viewer and voting kit support lessons, and the integrated 2 x 15 W speakers handle basic audio in smaller rooms.
Hotel meeting rooms and malls: portrait orientation suits agendas, wayfinding and event welcome screens, and the ambient light sensor can trigger programmed actions.

Planning power, climate and mounting

The panel weighs 48 kg and uses an 800 x 400 mm VESA pattern with M8 fixings. The SF680P wall mount and the EVER 350 Mobile Motor trolley are listed as options. A free site survey from SmartRooms Qatar lets our team check wall strength, cable routes and mounting height before delivery and installation.

Typical power draw is 170 W, and standby falls below 0.5 W in ECO mode. The power supply accepts 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Operating temperature is +5 to +35 °C at 20 to 80 % humidity, so install the panel in an air-conditioned room, away from direct sun and lobby doors where summer heat can rise above 45 °C.

Warranty and requesting a quote

The Sharp PN-LB753 carries a 3-year warranty that includes the backlight, with an optional fourth and fifth year extension. Ask SmartRooms Qatar for a quote that includes the panel, any mount or trolley you need, the USB-C cable length and a Wi-Fi dongle if required. Quotations are usually issued within one working day, and purchase orders and government tenders are welcome.

Questions about PN-LB753

Who is the Sharp PN-LB753 best suited for?

It suits organisations that hold regular meetings, lessons or presentations and need one large shared screen. In Qatar that could be a boardroom in West Bay, a seminar room in Education City or a classroom in Al Wakrah. The 75-inch panel suits medium to large rooms, so check seating distance with the SmartRooms Qatar team when you request a quote.

Does the PN-LB753 run apps without a connected PC?

Yes. It runs Android 14 on an octo-core processor with 8 GB RAM and 64 GB internal storage. Built-in applications include the Google Play Store, a web browser, a PDF viewer, a file manager and a whiteboard. The Android system carries Google EDLA certification. Whether a particular app works depends on that app's requirements, so test your key software before purchase.

How many touch points does it support, and does touch work with gloves?

The infrared touch system supports real multi-touch up to 40 touches and accepts finger, gloved hand and stylus input. Palm rejection is included, so a presenter can rest a hand on the glass while writing. Two passive pens with 2.6 mm and 6.8 mm tips are supplied, and Windows Ink is supported for handwriting. Touch accuracy is plus or minus 1 mm.

Which computers and operating systems work with the touch function?

Touch works with Android, Linux, Windows and Raspberry Pi, and with Mac OS for single touch only. It connects through a USB 2.0 full-speed HID interface that is powered over USB and works plug and play. If your Mac sources need multi-touch, plan for Windows or Android sources instead. Confirm your exact setup with SmartRooms Qatar before ordering.

Can a laptop show video, send touch and charge through one cable?

Yes, through the USB-C 1 port. It accepts video up to UHD at 60 Hz with DisplayPort alternate mode 1.4 and HDCP 2.3, carries the touch signal, and provides up to 100 W of power. This supports a bring-your-own-meeting setup where a visitor connects once and the laptop charges at the same time. USB-C cables of 5 m and 7 m are listed as options. Check that your laptop supports USB-C video output.

What inputs and outputs are available for multi-screen setups?

There are three HDMI inputs, with HDMI IN 3 also offering ARC. The HDMI output loops through the inputs, the USB-C port, the OPS slot and the internal Android system. USB-C also supports MST for multi-screen layouts. LAN, RS-232C and IR loop-through allow control within a larger network, and a recommended OPS Enterprise Pro or OPS Enterprise Ultra can be added to the slot.

Does it work on Qatar's 240 V mains supply?

Yes. The power supply is rated for 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical power consumption is 170 W, and standby drops below 0.5 W in ECO mode. For several panels on one circuit, ask SmartRooms Qatar to check the circuit and socket arrangement during the site survey, since the plug type should be confirmed for the installation.

Can it be placed in a hot room or a space without air conditioning?

No. The operating range is +5 to +35 °C with 20 to 80 % humidity, so the panel should sit in an air-conditioned room. Summer outdoor temperatures in Doha can exceed 45 °C, so keep the panel away from sun-facing windows and lobby entrances where heat builds. Storage range is -20 to 60 °C. Confirm room conditions with SmartRooms Qatar before installation.

Can it be used in portrait mode for signage or a kiosk-style display?

Yes. The panel supports portrait orientation, and the on-screen display can rotate for portrait use. It suits digital signage tasks such as a wayfinding screen in a shopping mall in Lusail or a welcome board at a hotel entrance. It is rated for 18 hours a day, seven days a week. Ask SmartRooms Qatar to review lighting and content playback before a public-facing installation.

What wall mount or trolley do I need?

The VESA pattern is 800 x 400 mm with M8 fixings. The panel weighs 48 kg, and the packaged weight is 59 kg, so plan delivery access and lifting equipment. Sharp lists the SF680P wall mount and the EVER 350 Mobile Motor trolley as options. A free site survey from SmartRooms Qatar checks wall strength, cable routes and mounting height before installation.

What does the warranty cover?

The panel carries a 3-year warranty that includes the backlight, with an optional fourth and fifth year extension from the manufacturer. Products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. Ask for the warranty details with your quotation so your procurement file records the exact coverage.

Can a school in Qatar order several units under one LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, and quotations are usually issued within one working day. A school fitting out several classrooms can request one quotation covering multiple PN-LB753 units, with mounts, USB-C cables and the optional Wi-Fi dongle listed separately. Payment by bank transfer, cheque or purchase order is available.
