Compatible LG monitors

This 19 V 2.1 A AC adapter replaces the LG ADS‑45FSN‑19 supply for monitors including 27EA33, 34UB67, 34UM67, 24MP57D, 24MP57HQ and 24MP57VQ. It matches the original part numbers EAY63190103, EAY63190001, EAY62790009 and EAY62768621. The unit is new and built to OEM specifications.

Power capacity and headroom

The adapter delivers 19 V at up to 2.1 A, covering the 1.3 A, 1.5 A and 1.6 A draws of the listed LG displays. It will run each supported monitor continuously but cannot power devices that require higher current or a different voltage.

Connector limits

A barrel plug with 4.5 mm inner and 6.4 mm outer diameter fits the compatible LG models; monitors using the 4.0 mm inner or 6 mm outer variant will not connect. Polarity and pin layout follow the original ADS‑45FSN‑19 design, so adapters with different tip dimensions are unsuitable.

Questions about this item

Will the 4.5 mm tip on this 19 V 2.1 A adapter fit the LG 27EA33 monitor I already own?

Yes — the adapter is listed for the 27EA33 and its 4.5 mm inside diameter matches the monitor's DC jack.

How can I confirm the adapter is delivering the correct 19 V output once connected?

Measure the DC plug with a multimeter set to DC volts; a healthy unit reads very close to 19 V under load.

Does the package include a mains lead or only the adapter brick with its 4.5 mm DC cable?

Only the adapter brick with attached DC cable is supplied; a standard IEC C7 figure-8 mains lead must be purchased separately.
