Overview

The Panasonic TH-55SQ3 is a 55-inch class 4K UHD professional display with a 3840 x 2160 panel, 500 cd/m² typical brightness and an anti-glare surface with 25% haze. It has three HDMI inputs, a PC input, RS-232C and LAN control, and built-in 20 W speakers. It suits meeting rooms, classrooms and retail areas in Qatar that need a display running around the clock.

What the TH-55SQ3 is built to do

The Panasonic TH-55SQ3 is a 55-inch class professional display from the SQ3 Series, with a measured screen of 54.63 inches (1387.8 mm). Its 16:9 panel renders 3840 x 2160 pixels, about four times the pixel count of a Full HD screen, so slide text, spreadsheets and fine graphics stay sharp at close range. It suits organisations that need a dependable screen for meetings, teaching or information display rather than a home television.

Brightness, glare control and power use

Typical brightness is 500 cd/m², typical contrast is 5000:1 and response time is 6.5 ms grey to grey. The anti-glare panel with 25% haze reduces reflections from windows and ceiling lights, and the 178° horizontal and vertical viewing angle keeps the picture readable from the side of the room. Average on-mode consumption is 138 W and standby is approximately 0.5 W. The power supply is rated AC 110 to 240 V at 50/60 Hz.

Connections for rooms with several sources

Three HDMI inputs with HDCP 2.2 support for laptops and media players
PC input on a Mini D-sub 15-pin connector, plus a stereo mini-jack audio input
USB Type-A port that plays 4K content from a memory stick
RS-232C serial control and an RJ45 LAN port compatible with PJLink
HDMI-CEC support for basic power operations on compatible connected devices

Where it fits across Qatar

At a private school in Al Wakrah fitting out new classrooms, the 55-inch size works as a teaching screen for a room where students sit at a comfortable distance. In a corporate office in West Bay, the display can serve as the main screen of a meeting room where teams in Doha connect with colleagues abroad, with a laptop, a conferencing system and a room PC each on its own input. In a clinic reception in Msheireb, the USB playback feature lets staff refresh a looping information screen by swapping a memory stick, without a computer beside the display.

What to plan before ordering

The unit measures 1242 x 713 x 66 mm and weighs approximately 15.6 kg, so the wall and bracket must be checked for that load. It mounts on a VESA-compliant 400 x 400 mm pattern with M6 screws and an 18 mm screw hole depth. It can be installed in landscape or portrait with a 0 to 20 degree forward or backward tilt, and the 55-inch model supports tilt up to 45 degrees for some mounting situations. The operating range is 0°C to 40°C at 20% to 80% humidity without condensation, up to 1400 m altitude; between 1400 m and 2800 m the limit is 35°C. Qatar summers regularly pass 45°C, so install the display in an air-conditioned room rather than a sun-exposed or unconditioned area, and confirm your room conditions during the free site survey.

SmartRooms Qatar supplies the TH-55SQ3 with delivery to all eight municipalities, professional installation and a free site survey before any wall fixing. Purchase orders and government tenders are accepted, and quotations are usually issued within one working day. Request a quote with your room size, wall type and planned content, and we will confirm the configuration for your site.

Questions about TH-55SQ3

What is the Panasonic TH-55SQ3 built for?

The TH-55SQ3 is a 55-inch class professional display for meeting rooms, classrooms, reception areas and retail floors. Its 3840 x 2160 panel and 500 cd/m² typical brightness suit organisations that show presentations, teaching content or information to groups in Qatar. It is a commercial display rather than a home television, so it suits offices, schools and public-facing sites that need a dependable screen for daily use.

What resolution and brightness does it offer?

The panel resolution is 3840 x 2160 (4K UHD), with approximately 8,290,000 pixels, and typical brightness is 500 cd/m². Typical contrast is rated at 5000:1 and response time at 6.5 ms grey to grey. These figures give sharp text for spreadsheets and clear video under ceiling lighting, though direct sunlight through a window will still reduce contrast, so the position of the screen matters.

Will the screen be readable in a classroom with windows?

The panel has an anti-glare surface with 25% haze, which reduces reflections from bright light such as ceiling lamps and windows. Its 500 cd/m² typical brightness helps in lit rooms. For a classroom or boardroom in Doha where direct sun falls on the screen, a site survey can check the angle of the glare so the display and blinds can be positioned to limit it.

Can it play announcements from a USB stick without a computer?

Yes. Insert a USB memory stick with numbered files stored in a folder named AUTO_PLAYBACK and playback starts automatically. The display is 4K compatible, so no PC or set-top box is needed. Still images and videos cannot be mixed on the same stick, and some files may not play even in supported formats. A clinic reception in Msheireb can use this to update a looping information screen; check the operation manual for file restrictions.

Which inputs does it have for laptops and room PCs?

The TH-55SQ3 has three HDMI inputs with HDCP 2.2 support, one PC input on a Mini D-sub 15-pin connector, one stereo mini-jack audio input, and a USB Type-A port rated at DC 5 V and 2 A with USB 2.0 support. Audio outputs are two RCA pin jacks. A meeting room in West Bay can keep a laptop on one HDMI input, a room PC on a second and a conferencing system on the third.

Can it be controlled by a room system or building management software?

Yes, through the RS-232C serial terminal, a 9-pin D-sub external control connector, or the RJ45 LAN port, which is compatible with PJLink and runs at 10BASE-T or 100BASE-TX. This suits a boardroom where a central control panel manages the display, or a school IT team that wants to check several screens over the network. Confirm the command details with SmartRooms Qatar before integration work begins.

Is it rated for continuous operation?

The manufacturer rates the SQ3 Series for constant 24/7 operation and positions it for public spaces such as train stations, airports and shopping malls, as well as control rooms. Daily operating time is listed as 24 hours a day. To limit image retention, the manufacturer advises showing moving content rather than leaving a still picture on screen for long periods. A hotel lobby in Lusail would plan a rotating playlist for this reason.

Can it be mounted in portrait orientation?

Yes. The display supports landscape and portrait orientation, and it tilts 0 to 20 degrees forward or backward in either orientation. The 55-inch model also supports a tilt up to 45 degrees in certain mounting situations. Portrait suits wayfinding or a corridor screen in an office or school, where tall content reads better. Confirm the orientation and tilt before the wall is prepared, because the bracket plan depends on it.

What wall mount and weight should I plan for?

The unit measures 1242 x 713 x 66 mm and weighs approximately 15.6 kg. It uses a VESA-compliant 400 x 400 mm wall-hanging pattern with M6 screws and an 18 mm screw hole depth. The bezel is 13.9 mm on all four sides, which keeps the frame slim in a room. A site survey should check the wall structure, especially lightweight partitions in offices and schools, before any bracket is fixed.

Can it run in Qatar's summer heat?

The rated operating temperature is 0°C to 40°C at altitudes up to 1400 m, with humidity from 20% to 80% and no condensation. Qatar summers often go above 45°C, so the display should sit in an air-conditioned room, not a sunny or unconditioned hall or outdoor area. Ask SmartRooms Qatar to confirm your room conditions during the site survey before ordering.

Does the power supply work with Qatar's 240 V mains?

The power supply is rated AC 110 to 240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical on-mode consumption is 138 W, standby is approximately 0.5 W and apparent power is 193 VA. The energy efficiency class for Europe is G. Your quotation will confirm the power cable and socket arrangement for your site.

Can a school order several units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. A private school in Al Wakrah fitting out several classrooms can send a quantity and room list and receive a quotation, usually within one working day. Products are covered by the manufacturer's warranty. Request a quote with your room sizes and mounting walls.
