50″ 4K 120 Hz commercial display

The LG 50UR640S9UD is a 50 inch commercial television built for continuous signage use. It delivers a 3840 x 2160 native resolution at a 120 Hz refresh rate on an IPS panel with 178 degree viewing angles. The webOS smart platform provides built-in content and group management tools alongside SuperSign CMS compatibility. Integrated Wi-Fi, Ethernet, Bluetooth and IR remote control complete the package.

Suited for signage installers needing network

This display fits installations that require IP-based management including Wake-on-LAN and Crestron Connected integration. The RS-232 port supports legacy control systems while three HDMI inputs and one USB handle source connectivity. Buyers needing higher peak brightness for direct sunlight or a wider colour gamut than NTSC should evaluate alternative models. Environments demanding display portrait orientation or video wall daisy-chaining are not addressed by this specification.

400 nit peak brightness with 330 nit typical

The panel reaches 400 nits peak and operates at 330 nits typical, providing clear visuals in standard indoor lighting conditions. The 120 Hz refresh rate ensures smooth motion for video and animated content. Built-in speakers handle basic audio without external amplifiers. The 178 degree viewing angle maintains colour consistency across wide seating areas. EPEAT compliance and Display Power Management support energy-efficient operation across deployed fleets.

Questions about this item

Do I need a separate media player to show 4K content at 3840 x 2160 on the webOS platform?

No, the built-in webOS smart platform can play 4K UHD content directly without an external player.

Can I daisy-chain an older display through the RS-232 port while using HDMI for the main source?

Yes, the RS-232 port supports serial control for daisy-chaining legacy displays while HDMI handles the primary 4K signal.

How do I confirm the panel is running at its native 120Hz refresh rate after installation?

Open the on-screen information menu; it will report a 120Hz refresh rate when a compatible 4K source is active.
