Monitor maximum draw is 48 Watts, power adapter:


Power Adapter can supply at max 48.07 watts (19V DC * 2.53 A).
Pretty sad actually. It's probably normal, if it's really bothering you, you can try and find another adapter with the
  • same pin/barrel connector (from another LG monitor or TV)
  • center pin positive polarity
  • 19V DC output
  • more than 2.53A current on the output .

Looks like it's an external AC-DC adapter. Generally these should get warm with use. Is it too hot / warm to tough with your bare hand? It should consume @ 44-48 Watts, the power supply for these seems to be able to handle 48 watts. (No overhead, kind of dumb?)


Make sure there is some room around the adapter (nothing covering it) and that it's not lying on something that would insulate it (carpet).

My current and previous main monitor have external bricks that get warm after some time. The previous monitor was going on about 5 years of use but I don't think there was any real sign of it "wearing out" or anything.

As long as it's not getting so hot you can't touch it for more than a few seconds, it should be fine.
