Matching Adapter for LG 27BL55U-B 27inch Monitor

This ABLEGRID AC adapter is built to power the LG 27BL55U-B 27inch IPS HDR UHD 4K monitor. It accepts AC 100-240V at 50-60Hz for worldwide use and delivers DC output through a barrel tip connector. The package includes the adapter unit and a separate power cable. It is a non-OEM replacement certified to CE, FCC and RoHS standards.

Steady Output with Protection Circuits

Over-voltage and over-heat protection circuits guard the monitor during extended sessions. The adapter maintains a stable DC supply across the full AC 100-240V input range without tripping. Keeping the unit in a ventilated area prevents heat build-up during continuous operation. It is not suited for buyers who need a battery-backed UPS for power-outage ride-through.

Simple Barrel-Tip Connection

Installation is a matter of matching the barrel tip to the monitor’s DC jack and plugging the IEC cable into a wall outlet. The tip size must match exactly; an incorrect fit will prevent power delivery. No drivers or configuration are required. Users who cannot verify the original adapter’s output polarity and tip dimensions should confirm those details before ordering.

Questions about this item

How much heat does the 100-240V adapter produce when the 27inch monitor runs all day?

The adapter includes over-heat protection and the supplier advises keeping it in a ventilated area during extended use.

Which cables must I already have to connect the adapter to the LG 27BL55U-B?

A standard AC power cord for the wall outlet is required; the barrel-tip DC lead to the monitor is included in the package.

Will this power supply work with an older LG monitor that uses a different barrel-tip size?

Only if the older monitor matches the same DC output voltage and barrel-tip dimensions; verify both before connecting.
