Hi there,

We have a LG 27UK850 which requires a power supply like this: Input:100-240V 50-60Hz (for worldwide use), Output:19V 7.37A ,Power:140W,DC pin sizes:6.5*4.4mm

Amazon.com: Original 19V 7.37A AC Adapter for LG 27UK850-W A16-140P1A IPS LED Monitor : Electronics

We need to buy a new one and was looking at this one from PB Tech: LG 210W 19.5V 10.8A Monitor/TV/Projector Charger - 6.5x4.4mm

Buy the OEM Manufacture For LG 210W 19.5V 10.8A Monitor/TV/Projector Charger -... ( NBPOEM19608 ) online - PBTech.co.nz

Can the electronic experts please let me know if this can be used as a replacement? I noticed that the amps are different but was wondering if it can be (stepped) down?

IIRC (not a sparky), long as voltages match, and amps matches or betters what you're after, you'll be OK.

The device will only draw the amps that it needs.

Also the plug needs to be correct... :)

The amp rating is invariably the maximum which the psu can supply. Provided the voltage is correct, the monitor will draw whatever current it needs up to this maximum.
So yes, this will be fine. Check the polarity on the DC plug though
