Replacement Power Supply

This 19V AC/DC adapter replaces the original power supply for LG monitors including the 27EA31V, 27EA31V-B, 27EA31VB and 28LJ4540 models. It delivers a stable 19.0V output required by these displays. The unit accepts a wide 100-240VAC input at 50/60Hz for worldwide use. Safety certifications include FCC, CE and RoHS compliance.

Build Integration and Cable Reach

The adapter connects directly to the monitor's DC input jack and plugs into a standard wall outlet without extra converters. A total 10 ft power cord provides generous reach for flexible desk or wall mounting. Built-in protections guard against over current, over voltage, short circuit and total power faults. The compact brick design keeps cable routing tidy behind the screen.

Capacity and Headroom

This supply matches the factory voltage and polarity for the listed 27" and 28" LG panels, ensuring reliable startup and steady operation. It handles the monitor's normal power draw with certified safety margins. The adapter is not suitable for devices requiring a different voltage, higher wattage or a proprietary connector. Buyers needing multi-device charging or laptop power delivery should look elsewhere.
