TH-55EQ3

What the TH-55EQ3 is and where it sits in the EQ3 Series

The Panasonic TH-55EQ3 is a 55-inch class commercial display from the EQ3 Series, with a 54.6-inch (1387.8 mm) 16:9 panel at 3840 x 2160 resolution. It targets entry-level professional installations: classrooms, conference rooms and indoor digital signage where a sharp 4K picture matters. The series runs from 43 to 86 inches across six models, so the 55-inch version suits mid-sized rooms rather than auditoriums.

Picture performance in rooms with windows and ceiling lights

The panel has a typical brightness of 500 cd/m², a typical contrast ratio of 5000:1 and a typical response time of 6.5 ms (G to G). Its anti-glare surface, with a 25% haze value, reduces reflections from ceiling lights and daylight. Viewing angles are rated at 178 degrees horizontally and vertically, so people seated at the sides of a room still see readable content. The 4K resolution carries roughly 8.29 million pixels, about four times Full HD, which helps with spreadsheets, timetables and small text.

Connections, control and playback without a PC

The rear panel provides three HDMI inputs with HDCP 2.2 support, a Mini D-sub 15-pin PC input, a USB Type-A port rated 5 V / 2 A for USB 2.0, a 10BASE-T/100BASE-TX LAN port and an RS-232C serial terminal. Network control follows the PJLink standard, so an external system can manage basic functions. Content can also play from a USB memory stick with no computer attached. Files must be numbered and stored in a folder named AUTO_PLAYBACK, and still images and video cannot be mixed on one stick.

Planning the installation in Qatar

• Size and weight: 1242 x 713 x 66 mm, about 15.6 kg, with a 13.9 mm bezel on all four sides.
• Wall mount: VESA 400 x 400 mm pattern with M6 screws and 18 mm screw depth.
• Orientation: landscape or portrait, with up to 20 degrees of tilt in landscape.
• Power: 110 to 240 V AC, 50/60 Hz; 142 W at shipping condition, 138 W average in on mode.
• Environment: 0 to 40 °C up to 1400 m altitude, 20 to 80% humidity without condensation.

Doha summer temperatures can exceed 45 °C, so install the display in an air-conditioned room and keep the surroundings within the rated range. A free site survey from SmartRooms Qatar lets the team check wall construction, cable routes and outlet positions before the unit goes up.

Where it fits across Qatar

In a private school classroom in Al Wakrah, a 55-inch panel on the front wall can show lessons from a teacher laptop over HDMI, with the built-in 20 W speakers (10 W + 10 W) suiting a classroom-sized space. In a West Bay meeting room, the PC input and LAN control let a team in Doha run presentations and join calls with colleagues abroad. In a shopping mall lobby at The Pearl, a looped USB playlist can run for long days, as the EQ3 Series is rated for 18 hours of daily operation. Avoid leaving a static slide on screen for long periods, since image retention can remain; alternate with moving content.

Larger halls usually need separate audio, so plan that alongside the display. To request a quote for one unit or a full rollout, send your room list and wall details to SmartRooms Qatar; quotations usually arrive within one working day.
