Signage apps for LG almost all need an LG webOS Signage display, LG's commercial line, not a consumer LG smart TV. A consumer LG TV cannot open an app by itself when it powers on, so the only options there are signage pages in the TV's web browser. The cheapest reliable setups are a webOS Signage display with a free one-screen plan, or any LG TV plus a small player on its HDMI port.
Can a consumer LG smart TV run digital signage?
Not reliably. Consumer LG TVs and LG's signage displays both run webOS, but they are different products:
- No signage apps. Yodeck, OptiSigns, Play Digital Signage, ScreenCloud and NoviSign all support only LG's commercial signage displays. Fugo's consumer app is still in development.
- No auto-start. webOS for TVs has no way to open an app when the TV turns on. After every power cut, someone opens it again with the remote. Play Digital Signage gives this, and no crash recovery, as its reason for not supporting consumer LG TVs.
- Browser only. Some services run in the TV's web browser instead: Screenly Anywhere and Juuno, for example. The same restart problem applies, and Juuno warns of lag on older TVs.
- Auto Power Off. The TV switches off if no button is pressed for a set time. Turn it off under Settings > General > Energy Saving.
- Screensaver ads. LG can show full-screen ads on the screensaver. Turn off "Screen Saver Promotion" and "Home Promotions" in the TV's Additional Settings menu.
- Warranty. LG's US TV warranty excludes commercial use, including offices (LG warranty).
A browser page on a consumer LG TV works for a staff room where someone switches the TV on each day. Not for a menu board or a shop window.

Sources: each vendor's LG setup page, read October 2026 (Yodeck, Play, OptiSigns, ScreenCloud, NoviSign, Fugo).
Check the display's webOS version first: it decides which apps fit. Yodeck skips webOS 3, 5 and 7. ScreenCloud limits webOS 4.1 displays to images, documents and video because their built-in browser no longer gets security updates.
The free and cheap options
Free:
- The display's own player. webOS Signage displays have a built-in Contents Manager and Local Contents Scheduling: copy images and video onto the display (by USB or over the network) and set a schedule. No cloud, no fee. Fine for one screen you rarely change.
- LG Simple Editor: LG's free tool for making simple layouts for its signage displays (LG SuperSign).
- LG SuperSign Control+: the basic version is free for up to 100 displays. It monitors and controls displays (power, input, settings), not content.
- Yodeck Free: one screen, no time limit, on a webOS Signage display. Limits on webOS: 1080p video at most, no YouTube live streams.
- Play Digital Signage: the first screen is free, on webOS 6 Signage displays.
- Xibo self-hosted: the CMS is free and open source, but the webOS player licence costs £60 per display, once, and you run the server.
LG's own content tools, SuperSign CMS and SuperSign Cloud, are paid, with no free tier.
Cheapest paid, per screen per month:
- Play Digital Signage Essential: $7.20 billed annually (at 4 screens), $8 monthly.
- Yodeck Basic: $8, billed annually or monthly.
- OptiSigns Standard: $9 billed annually, $10 monthly.
- Rise Vision Basic: $11 billed annually, $12 monthly.
- Xibo hosted: £3.50 per display, webOS player included.
LG webOS Signage or a consumer LG TV?
A webOS Signage display costs more than a consumer TV of the same size. What the extra pays for:
- Hours. Models are rated for 16 hours a day (for example the UL3J series and the UR640S) or 24/7 (the UH5N series). Pick 24/7 for a screen that never goes off.
- Apps that start by themselves. You install a vendor's player through SI Server Settings (a web address) or a USB stick, and the display opens it at every start.
- Power On Status. Set it to turn on, stay in standby or return to its last state after a power cut.
- Failover. If the main source fails, the display switches to a backup input or to content stored on it, instead of a blank screen.
- Business warranty. LG's signage displays carry a 3-year warranty for commercial use.
LG's UR640S "Signage TV" sits between the two: a TV tuner plus a 16/7 rating, the built-in Contents Manager, scheduling and failover.
How to install a signage app on a webOS Signage display
- On the display's remote, open the settings menu and find SI Server Settings. Where it sits varies by webOS version; your vendor's LG setup page shows the path.
- Turn on SI Server and enter the address from your signage vendor's LG page (for example, Yodeck's is
yodeck.link/webos). - Restart the display. It downloads and opens the vendor's app, which shows a pairing code.
- Enter the code in your signage account and assign content.
- Set Power On Status to last state, so the screen comes back after a power cut.
No network access to the settings menu? Most vendors also offer a USB install file.
Where Brix fits
Brix has no app for LG TVs or displays. It runs on a player plugged into the HDMI port: the Amazon Signage Stick ($99.99), Fire TV, an Android box or a Windows PC. That works on any LG, consumer TV or webOS Signage display, whatever its webOS version.
- Price: $6 per screen per month billed annually, or $8 billed monthly, every feature on one plan. Plus $99.99 once per Stick.
- Remote control on the Stick: restart it, take a screenshot and turn the TV on and off over HDMI-CEC from the CMS. This fixes a consumer LG TV's weak point: the Stick opens Brix by itself after a power cut, and it switches the TV on each morning.
- Setup: about 10 minutes per Stick. Across the Signage Sticks running Brix, pairing takes a median of 2.6 minutes.
- Moving from another CMS: we move your content, playlists and screens for you, free, usually in a day.
Brix is not the right choice if you want no box behind the screen. On webOS Signage displays, Yodeck, Play or the display's own Contents Manager run with nothing added. On an LG TV, turn on SIMPLINK (LG's name for HDMI-CEC), or the Stick cannot switch it on and off. For Samsung screens, see Samsung Smart Signage vs smart TVs; for any other TV, use existing TVs for digital signage.
