For just $275, down from its list price of $799.99. That is $180.87 below the 90-day average of $455.87 and well under the 180-day mark of $449.10.

Commercial displays in this class rarely see discounts this steep outside bulk procurement cycles, making this a pricing anomaly worth acting on.

What You're Getting

The LG 43UL3J-M is a 43-inch UHD display built for signage, conference rooms, and commercial installations. It packs three HDMI inputs (HDCP 2.2 and 1.4), a RS-232C input via 4-pin phone-jack, RJ45 LAN connectivity, and USB ports for media playback and daisy-chain control. The panel delivers 3840x2160 resolution with direct-lit LED backlighting, and the webOS smart signage platform supports content management without a separate media player. VESA mount compatible for flexible installation.

Who This Is For

Best for IT managers outfitting meeting rooms, digital signage operators, and anyone setting up a commercial AV system who needs RS-232C control and LAN integration in a single display. The connectivity suite eliminates the need for external control boxes in many setups.

Skip this if you just want a basic living room TV. The commercial feature set and lack of a TV tuner make it overkill for home use.

Final Verdict

A $524.99 discount on a commercial UHD display with full RS-232C and LAN control is rare. If your next AV install calls for a 43-inch panel with serial control and network management. This is the price to lock in.
