[SOLVED] Is it normal for the monitor's mains adapter to get hot ?

[radicle_]

I have LG 27GN750 monitor
240hz 1ms gsync

is it normal that its adapter get hot after 30 mins or more usage?

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?)

New 4k monitor's power brick is getting toasty

I just bought a 4k LG monitor a few days ago and in the process of cable managing it, I noticed that the power brick is getting pretty hot. I have no reason to believe it'll ever get too hot to touch, but it is by a wide margin warmer than any other power bricks I have around. The monitor doesn't...

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).

What is "hot"? just like other psu's is there a portion of power that gets transferred into heat because of it not being 100% efficient so that it get warm/hot can be expected.

It's okay to be concerned, but it's normal behaviour.

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 .

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.
