19V AC Adapter for LG Monitors

This 19V AC adapter replaces the original power supply for LG UM57, 25UM57, 34UM58-P, 34UM68-P and 29UM58-P monitors. It also supports N225WU and N225WU-BN models plus 19 to 27 inch LED LCD HDTV displays. The unit accepts 100-240VAC at 50/60Hz for worldwide use. It is a new, direct replacement built to OEM specifications.

Ten-Foot Cord and Safety Protections

The adapter includes a total 10 ft long power cord for flexible placement. Built-in safeguards provide over current, over voltage, short circuit and total power protection. Additional features cover overload, over-charge, overheating and anti-interference protection using smart chip and isolation materials. FCC, CE and RoHS certifications confirm compliance with safety and environmental standards.

Fixed 19V Output and Connector Limits

This adapter delivers a fixed 19V output only, so it cannot power devices requiring a different voltage. The barrel connector fits the listed LG models but is not interchangeable with other brands or sizes. Buyers needing adjustable voltage, USB-C PD or a second simultaneous output cannot use this unit. The 10 ft cable length is fixed and cannot be extended without an approved coupler.

Questions about this item

How often will the 10 ft power cord need replacement under normal use?

The 10 ft cord is built with high-quality wires and overload protection; inspect it periodically for wear, but no fixed replacement interval is defined.

What limits continuous operation of the 19 V adapter first?

Over-current, over-voltage, short-circuit and over-temperature protections will shut the unit down before any component reaches its thermal limit.

How much heat and noise does the 19 V supply produce when running all day?

The adapter has no fan, so it runs silently; its smart chip and isolation materials keep surface temperature low during sustained 100–240 VAC input operation.
