55SH7DD

What the LG 55SH7DD is and why it is discontinued

The LG 55SH7DD is a 55-inch Full HD signage display from the SH7D series, built for content that must stay readable in bright public spaces. The manufacturer has discontinued this model, so this page is written for three groups: organisations that already run one, buyers comparing it with newer displays, and anyone who needs a like-for-like replacement in Qatar. Our quotation will confirm which current equivalent or compatible replacement we can supply.

Brightness and picture quality on an IPS panel

The panel delivers a 1,920 x 1,080 resolution and a typical brightness of 700 cd/m². That output lets moving content hold its impact in lobbies, corridors and shopfronts where a dimmer screen would be hard to read. IPS technology keeps colours clear when people view the screen from the side, so a display in a mall concourse or a bank hall stays readable from several positions.

Content playback, control and network management

Staff can load a playlist onto a USB drive, set timings and run the schedule without a separate media player or server. If the input signal drops, the screen can show a preset image from USB instead of the standard no-signal message. Connections include two HDMI inputs, a DVI input, an RGB input, an audio input, a USB 2.0 port, RS232C input and output, an RJ45 port and an IR receiver input. SNMP support helps network managers, and a time zone set at installation lets the display sync with an NTP server. Several units can be grouped over RS232C to adjust local time together when no network is connected. The unit is not OPS compatible, so an external media player such as the MP500 or MP700 is the route for a separate player.

Where it fits in Qatar

• Shopping mall concourse in Doha: a 55-inch unit above a store entrance that changes promotions on a timed schedule, with the detachable logo set for portrait or landscape to suit the shopfront.
• Hotel lobby in West Bay: arrival information and event listings where the built-in speakers add audio to a short message.
• Government service hall in Msheireb: queue information and notices, with a preset image shown when the feed is interrupted.

Planning the installation and power

The monitor measures 1,238 x 714.9 x 54 mm and weighs 17.5 kg as a head unit. It uses a 300 x 300 VESA pattern, so the optional LSW350B wall bracket or AM-B330S VESA adapter can be fitted, and the ST-492T stand is available for freestanding use. Bezels are 11.9 mm on the sides and top and 18 mm at the bottom. The built-in power supply accepts 100-240V at 50/60Hz and draws a typical 95 W, falling to 75 W in smart energy saving mode, which the manufacturer rates at roughly 32% below a conventional model at equal luminance. The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summers regularly pass 45°C, so the display should sit in an air-conditioned indoor area within that range. For any window-facing or semi-outdoor position, confirm conditions with the SmartRooms Qatar team before ordering. We offer a free site survey before wall mounting and professional installation.
