LH5581UHSG-1AG

A 55-inch 4K panel with a removable frame

The LH5581UHSG-1AG is a 54.6-inch display with a native 3840 x 2160 resolution, giving 8.3 million pixels and a pixel pitch of 0.315 mm. Its VA panel has anti-glare coated glass, a brightness of 500 cd/m² and a static contrast of 5000:1. Viewing angles are rated at 178 degrees horizontally and vertically, so people standing to the side of a lobby can still read the same message.

The frame sets this model apart from a standard screen. It is white, matte and magnetically attached, so it can be removed and replaced with a custom wrap that matches a brand, a season or a room. The bezel measures 14.5 mm on the sides and 14.3 mm at the top and bottom, a narrow border that matters when several panels sit side by side.

Android 14, iiSignage² and connectivity

The display runs Android 14 with a quad-core processor, 4GB of RAM and 32GB of storage, so applications can be installed directly on the unit. The bundled software covers content management through iiSignage², device management through iiControl and wireless presentation through iiShare, along with a PDF and media player and a browser. Built-in WiFi on 2.4 GHz and 5 GHz, an RJ45 LAN port, two HDMI 2.0 inputs and a USB-C 3.2 input with DisplayPort Alt mode and 15W power delivery give IT teams several ways to connect content and control.

For control, the unit provides RS-232c and IR, with an RS-232c output and an IR loop-through for chaining units. Its two 10W speakers and 3.5 mm audio output suit short announcements, though a dedicated sound system is better for a large venue.

Where it fits in Qatar

A boutique in Msheireb or The Pearl can mount the panel on an interior wall away from direct sunlight and change the frame with each campaign. A hotel lobby in West Bay can show wayfinding or event schedules in portrait orientation, which the display supports. A government office in Doha or Al Sadd can use it as a visitor information board whose content changes through the day, with scheduling and an off timer controlled remotely.

Waiting areas in clinics, banks and service centres are another good fit. The unit is rated for 24/7 operation and has anti image retention and a fanless design, so an information loop in a waiting area in Al Rayyan or Lusail can run through the working day.

What to plan before you order

• Check the 0°C to 40°C operating range against the room. Summer temperatures in Qatar can exceed 45°C, so install in an air-conditioned space away from outdoor entrances.
• Plan the wall for 18.4 kg without its box. Use the included VESA 300 x 400 mm bracket and book a free site survey before mounting, especially for a row of units.
• Confirm the power connection. The internal supply accepts 100 to 240V at 50/60 Hz, typical draw is 104W and a 1.8m power cable is included, but the plug type is not listed in the data, so confirm it with the team.
• Decide how content reaches each unit, over wired RJ45 or built-in WiFi, and check your network rules before installation.

Schools, government entities and companies buying several units can order against a purchase order (LPO) or a government tender, including Monaqasat. SmartRooms Qatar accepts bank transfer, cheque or purchase order payment. Send the number of units, the room conditions and your network details, and request a quote. Quotations are usually returned within one working day.
