LG 22SM3G 22-inch Full HD Standard Signage Display

Overview

The LG 22SM3G is a 21.5-inch Full HD signage display with an IPS panel, 250 nit typical brightness and built-in webOS 4.1, so it plays content without an external media player. Two HDMI inputs, a LAN port and built-in Wi-Fi make it suitable for reception desks, retail counters and corridors in Doha, Lusail and Al Wakrah.

What the 22SM3G is built for

The LG 22SM3G is a Full HD signage display built around a 21.5-inch IPS panel with a 1920 x 1080 native resolution. LG markets it as a 22-inch model, so the panel measurement is the figure to use when checking wall space against the monitor dimensions of 510.3 x 302.1 x 53.8 mm. It suits shops, reception areas and offices that need one screen running menus, schedules or information loops for long daily hours, with the panel rated for 16 hours a day, 7 days a week.

Playback without an external media player

Content runs on the built-in webOS 4.1 platform, powered by a quad-core SoC that handles several tasks at once. Local content scheduling, Group Manager and USB Plug and Play let staff load and manage playlists without a separate media box. If a source fails, the fail over function switches to a backup source prepared in advance. The display also supports PIP and 2PBP split-screen layouts and can rotate between portrait and landscape orientation.

Key specifications that matter for planning

Panel: 21.5-inch IPS, edge backlight, 250 nit typical brightness, 1,000:1 contrast, 178º x 178º viewing angle
Colour: 16.7 million colours with BT709 95% colour gamut
Connectivity: two HDMI inputs with HDCP 2.2, audio in, RS232C in, one RJ45 LAN port, IR in and one USB 2.0 Type A port
Wireless: built-in Wi-Fi and Bluetooth, with Beacon and BLE support
Power: AC 100-240V, 50/60Hz, typical 30W and maximum 33W
Environment: operating temperature 0 °C to 40 °C and humidity 10% to 80%

Where it fits in Qatar

A clinic reception area in Al Sadd can use the screen to show queue information and health messages, with the 16.3 mm even bezel keeping the display neat on a counter wall. A retail unit in a Lusail mall can run promotions and use Beacon and BLE support to push coupons and information to shoppers in real time. A government office in Doha working in Arabic and English can set on-screen menus to Arabic, as the display's language list includes it.

What to plan before installation

Check the source devices first. The 22SM3G has two HDMI inputs but no DisplayPort, DVI or RGB input, and no HDMI output or daisy chain, so each display needs its own HDMI source. Plan the mount around the 100 x 100 mm VESA interface and a head weight of 3.34 kg. Summer temperatures in Doha can pass 45°C, but the rated maximum is 40°C, so install the screen inside an air-conditioned space and confirm the environment before you order. Confirm that the supplied power cord suits BS 1363 sockets. The manufacturer lists five years of security updates from the product launch date.

Questions about 22SM3G

What is the LG 22SM3G best used for in Qatar?

It suits single-screen messaging where content must run daily without a separate media player. Typical sites include clinic waiting areas in Al Sadd, retail counters in Lusail malls and office reception desks in Doha. Its 21.5-inch IPS panel and 250 nit typical brightness suit indoor spaces, and it is rated for 16 hours a day, 7 days a week.

Is the 22SM3G a 22-inch or a 21.5-inch screen?

LG markets the model as a 22-inch display, but the panel's measured screen size is 21.5 inches. When planning wall space or ordering frames, use the 21.5-inch panel size together with the monitor dimensions of 510.3 x 302.1 x 53.8 mm. SmartRooms Qatar can confirm the exact fit during your quotation.

Do I need a media player to run content on the 22SM3G?

No. The display runs content on its built-in webOS 4.1 platform with a quad-core SoC, so an external media player is not required for playback. Staff can schedule content locally, manage groups of displays and load content from a USB drive using USB Plug and Play, which is useful for updating menus in a shop.

Which inputs does the 22SM3G have?

It has two HDMI inputs with HDCP 2.2, audio in, RS232C in, one RJ45 LAN port, IR in and one USB 2.0 Type A port. It has no DisplayPort, DVI or RGB input and no HDMI output. A source with only VGA or DisplayPort output will not connect directly, so confirm your laptop or media device outputs before ordering.

Can the 22SM3G be installed in an unshaded lobby or near a window in summer?

The stated operating range is 0 °C to 40 °C with 10% to 80% humidity. Summer temperatures in Doha can exceed 45°C, so install it inside an air-conditioned space, away from direct sunlight and dust-prone entrances. The source data does not list outdoor or sunlight ratings, so confirm the exact location with the SmartRooms Qatar team before installation.

Does the on-screen menu support Arabic?

Yes. The on-screen display language list includes Arabic alongside English, French and many other languages. This suits Qatari government offices, schools and businesses that work in Arabic and English side by side. Staff can switch the menu language on the display itself, so one screen can serve both language groups without a separate setup.

How do I mount the 22SM3G on a wall or counter?

The display uses a 100 x 100 mm VESA mount interface, and the head weighs 3.34 kg without packaging. Choose a bracket rated for that weight and check the wall or counter structure first. SmartRooms Qatar offers free site surveys before wall-mounting, and the team can advise on bracket type and cable routing for your location.

Can I manage several 22SM3G displays across different sites?

Yes. Control Manager is an embedded web monitoring solution that lets you check and control multiple displays in different locations in real time from internet-connected devices. The model also supports SNMP, Wake on LAN, status mailing, SuperSign CMS, SuperSign Control+ and SuperSign WB, and Connected Care is listed as compatible. SuperSign Cloud is not supported.

Does the 22SM3G have sensors for environmental monitoring?

It has a built-in temperature sensor and supports external sensors such as GPIO, NFC/RFID and temperature sensors connected via USB. It does not include a built-in auto brightness, proximity or humidity sensor. This suits sites that need to log conditions beside the screen, such as a storage room, but external sensor models and drivers should be confirmed before purchase.

How much power does the 22SM3G use, and what does it add to cooling load?

Typical consumption is 30W and maximum is 33W, with Smart Energy Saving listed at 15W plus or minus 5%, and power-off draw at 0.5W. Heat output is listed at 103 BTU/hr typical and 113 BTU/hr maximum. This is a small load per screen, but it should be included when sizing air conditioning for a reception area with several displays.

Does the 22SM3G carry Energy Star or ERP certification for government tenders?

No. The source data lists no ERP or Energy Star certification, and no ePEAT rating. It holds CB/NRTL safety certification and carries FCC Class A and CE EMC marks. If your Monaqasat tender or ministry specification requires specific certificates, tell the SmartRooms Qatar team when you request a quote so the correct product can be confirmed.

What comes in the box with the 22SM3G?

The basic package includes a remote controller with two batteries, a power cord, a quick start guide, an HDMI cable, a phone-to-RS232C gender adapter, an external IR receiver and an IR sheet. No optional accessories are listed for this model. Confirm any additional brackets or cables you need when you request a quote from SmartRooms Qatar.

Can a school or ministry order several 22SM3G units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and supports payment by bank transfer, cheque or purchase order. For a school fitting out several corridors or classrooms, send the room list, mounting positions and source devices together so the quotation covers all units and any mounting work at once.
