LG monitor power replacement

This AC adapter supplies 19 V to 20 V DC at up to 4 A for compatible LG LED and LCD monitors. It replaces lost or damaged original power supplies for screen sizes from 19 inches to 34 inches. The unit accepts 100 V to 240 V AC input for worldwide use.

Connector and voltage check

Verify that your monitor requires a DC barrel connector with a 4.4 mm inner diameter and 6.5 mm outer diameter. Confirm the label on your display shows an output requirement within the 19 V to 20 V range and a current draw no higher than 4 A. The adapter uses a three-prong IEC inlet for the included mains cord.

Build and daily use

The adapter body is a sealed plastic enclosure with an integrated output cable ending in the specified barrel tip. A detachable three-prong AC cord connects to the IEC socket on the brick. No fan is present, so operation is silent on a desk or behind a monitor. The fixed DC cable length determines placement relative to the display.
