What the TH-55SQ1 delivers in a 55-inch frame

The Panasonic TH-55SQ1 is a 55-inch class 4K UHD LCD display from the SQ1 Series, built for digital signage, meeting rooms and public information points. Its 3840 x 2160 panel delivers about 8.3 million pixels across an active area of 1209 x 680 mm, so text, spreadsheets and fine graphics stay sharp at close viewing distances. Panasonic has discontinued the TH-55SQ1. Organisations that already run this model, and buyers comparing it with newer displays, can request a quote for a current equivalent or a compatible replacement from SmartRooms Qatar.

Picture and content controls that matter on site

The panel has a typical brightness of 500 cd/m², a typical contrast ratio of 1100:1 and an 8 ms response time (G to G). It plays HDR content in PQ and HLG formats and includes an emulation mode for the BT.2020 colour gamut. Twelve-axis colour management lets an installer adjust colour temperature, shade and brightness for red, green, blue, cyan, magenta and yellow, which helps a brand's artwork match across several screens. The display menu offers modes including Vivid signage, Natural signage, Standard, Surveillance and Graphic, so one panel can suit different content and rooms.

Where it fits in Qatar

Meeting rooms in West Bay or Lusail: a 55-inch panel suits a small or medium boardroom where participants sit close. Its 178 degree viewing angle keeps the picture readable from the side of the table.
Schools in Education City or Al Sadd: Screen Transfer software can push announcements to up to 64 displays over wired LAN, with a priority function for urgent messages.
Retail and lobbies in The Pearl or Msheireb: the built-in USB media player starts playback from a memory stick without a PC, so promotions can loop on a simple setup.
Control rooms in Mesaieed or Ras Laffan: failover and failback switch to alternative signals when the main feed drops, although the usable main and backup combinations are limited.

What to plan before installation

Check the wall and bracket first. The display measures 1240 x 714 x 74 mm including handles, weighs approximately 25.5 kg and uses a 400 x 400 mm VESA pattern. The 55-inch model tilts from 0 to 45 degrees forward or backward in both landscape and portrait. Its operating environment is rated at 0 to 40 °C and 20% to 80% humidity, non-condensing. Qatar summers can exceed 45 °C, so the room needs dependable air conditioning, and the mounting position should be confirmed with the SmartRooms Qatar team. Power input is 110–240 V AC at 50/60 Hz with a power consumption of 300 W. For 4K video over DIGITAL LINK, plan cable runs up to 50 m of CAT5e or higher STP cable.

Ordering and next steps

Questions about TH-55SQ1

Is the Panasonic TH-55SQ1 still available from SmartRooms Qatar?

Panasonic has discontinued the TH-55SQ1, so it may not be available as new. SmartRooms Qatar can quote for a current equivalent or a compatible replacement. Send the room size, mounting wall and content sources, and the team will respond with a quotation, usually within one working day. Stock levels and lead times are confirmed with the quotation.

Is a 55-inch SQ1 panel the right size for a meeting room in West Bay?

A 55-inch panel suits a small or medium boardroom where participants sit within a few metres of the screen. Its active area of 1209 x 680 mm gives a clear view of slides and spreadsheets without dominating the wall. Larger SQ1 sizes such as the 65-inch and 86-inch models suit lecture halls or large boardrooms, so measure the seating distance before choosing.

How bright is the screen, and will it work in a room with strong sunlight?

The panel has a typical brightness of 500 cd/m² and a typical contrast ratio of 1100:1, with an anti-glare surface (haze 28%). Its operating environment is rated at 0 to 40 °C and 20% to 80% non-condensing humidity. Rooms with windows facing the sun need shading and dependable air conditioning, and the SmartRooms Qatar team can confirm the position before installation.

Does the TH-55SQ1 support HDR content?

Yes. The SQ1 Series supports HDR in PQ and HLG formats, so highlights and shadows in compatible footage show more detail. The display also includes an emulation mode for the BT.2020 wide colour gamut. This is useful for a retail brand in Msheireb or a media team in Doha that needs its artwork to look consistent on screen.

Can a retail store in The Pearl run promotions from a USB stick without a PC?

Yes. Inserting a USB memory stick with saved content starts playback automatically, and the display supports still image formats including JPG and BMP as well as video formats including MP4, MOV and AVI. Some files may not play even when the format is supported, so test the files on the display before a campaign goes live.

Which inputs and outputs does the TH-55SQ1 provide for a PC or video source?

The display has two HDMI inputs with HDCP 2.2, a DVI-D input, a Mini D-sub 15-pin PC input, a DisplayPort input and a DisplayPort output. The DisplayPort output allows daisy-chaining for 4K images across several units. DVI-D does not support 4K signals, so use HDMI or DisplayPort for 4K sources such as a presentation PC in a boardroom.

How far can a cable run from the source to the display?

DIGITAL LINK carries video, audio and control over a single CAT5e or higher STP cable. The source data gives 50 m for 4K video. Full HD transmission reaches 150 m only with the optional ET-YFB200G DIGITAL LINK Switcher in Long Reach Mode. A school campus in Education City with long corridors should plan cable routes and switchers during the site survey.

Can a school in Qatar push announcements to all of its classrooms at once?

Yes, with the free Screen Transfer software, version 2.0 or later, which shows a PC screen on up to 64 displays over wired LAN. Staff can confirm distribution status from a PC, and the priority function can switch displays on and show urgent messages. The software needs the Software Main Version 4.40 or later on the display, so confirm firmware before purchase.

Is the TH-55SQ1 suitable for a control room at an industrial site such as Mesaieed?

The SQ1 Series includes failover and failback, which switches to alternative video and audio signals when the main feed is interrupted and returns to the original image once it is restored. The usable combinations of main and backup signals are limited, so confirm the input pairing with the SmartRooms Qatar team before specifying the control room layout.

Can the display run 24 hours a day in a busy public area such as an airport or hotel lobby?

The data rates the display for 24 hours a day operation and describes use in public spaces such as airports and shopping malls. To reduce image retention, show moving content where possible, because a still picture left on screen for a long time may leave a ghost image. Confirm the lobby climate and the content schedule when you request a quote.

How heavy is the panel, and what wall mount does it need?

The display weighs approximately 25.5 kg and measures 1240 x 714 x 74 mm including handles. It uses a 400 x 400 mm VESA mounting pattern and tilts from 0 to 45 degrees in landscape and portrait. SmartRooms Qatar offers a free site survey before wall-mounting, so the wall structure and bracket can be checked before the panel is fitted.

Does the power input suit Qatar's electrical supply?

The power input is 110–240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains supply. Power consumption is listed as 300 W, with approximately 0.5 W in standby and 0.3 W when powered off. Ask the team to confirm the power outlet and cable arrangement for your room when you request a quote.
