Compatible LG monitor power adapter

The GreenTech LCAP31 is a 19V 140W AC adapter built to replace the original power supply for a long list of LG UltraWide and UltraFine monitors. It delivers 7.37A through a 6.5 x 4.4mm barrel connector and carries CE, FCC and RoHS safety certifications. The unit is supplied new in black finish.

Buyers with a matching LG display

This adapter fits the models listed in the specifications, including 27, 29, 32, 34 and 38 inch LG monitors and several LG TV references. It is not suitable for devices that require a different voltage, a higher wattage or a connector size other than 6.5 x 4.4mm. Shoppers needing a USB-C power delivery brick should look elsewhere.

Deciding specification — 6.5 x 4.4mm barrel

The plug dimensions are the single detail that determines whether this unit will physically connect to your monitor. Verify the centre pin and outer diameter on the original adapter or the device label before ordering. If the connector matches, the 19V 140W output aligns with the OEM specification for the supported LG models.

Questions about this item

Will the LCAP31 19V 140W adapter work with an older LG 27UD88 monitor that originally used the EAY62949010 part?

Yes, the LCAP31 replaces OEM part EAY62949010 and is listed as compatible with the LG 27UD88 and 27UD88-W models.

How can I confirm the 6.5 x 4.4mm connector is delivering the correct 19V 7.37A output after I plug it in?

The adapter is tested for correct voltage, stable current and circuit protection; the monitor should power on normally with no flickering or warning messages.

Does the box include a mains power cord or only the adapter brick with the 6.5mm barrel plug?

The product is the AC adapter brick with the 6.5 x 4.4mm barrel connector; a separate IEC C5 or C7 mains lead is required and not included.
