LG webOS Signage
Use LG’s webOS Signage panels to run OneDisplay natively without an external player.
LG webOS Signage panels have a capable built-in web runtime, ideal for clean all-in-one deployments.
Compatibility
We support common professional lines across webOS Signage generations. Examples:
- UH5F-H (mainstream pro line)
- UL3J, UR640S (entry/SMB signage)
- SM5J and similar SM/UM/UH lines
- XE outdoor lines
✅ Recommendation: Choose UH5F-H (or current UH successor) for premium installs, UL3J/UR640S for budget-friendly.
Requirements
- webOS Signage with URL Launcher/SI Server support
- Stable network (HTTPS)
- Accurate time (NTP or network sync)
Setup (overview)
- On the panel, open URL Launcher (or SI Server) and set the OneDisplay player URL.
- Enable Auto Launch on power-on.

🧰 For mass rollouts, LG SuperSign or partner tooling can push network/URL settings.

Gotchas & tips
