Information needed - Display that produces less heat

[JamesTuckerTPA]

This does not seem to be a consideration for most, but I live in a hot climate in an hold house, and I'm looking for monitors that throw off less heat to the room (if even possible).

 

I turn my present displays off and the room cools from 80F down to 76-77F.

 

Is looking at wattage pull a good indicator of possible heat output? Is there anything else I could look for in the specs online?

I cant imagine that idle monitors are raising your room temp by 4 degrees. when you turn off your monitors, your pc is also off i would guess, and that's where the temperature drop comes from.

 

My monitor (LG gn950) is listed as 95w maximum, where my pc is running off of a 750w power supply...

 

all that being said, wattage drawn will be pretty directly related to heat output, but also related to how good the monitor is to some extent. the lowest power draw monitors will be the smallest, dimmest, lowest refresh rate, etc, compared to a better monitor.

The amount of power a monitor consumes is relatively constant and depends on the brightness level you set.

If your monitor comes with a 60w power supply, it won't consume more than 60 watts at 100% brightness.

 

Your computer consumes variable amount of power, when you're gaming the video card can jump in power consumption from something like 10 watts (in windows, in 2d applications) or 15w or so (when watching movies, youtube) all the way to 200-300 watts or even more while in games.

 

Depending on video card, you can enable features of the video card to reduce power consumption. for example amd has Chill and other features that can make a video card limit the number of fps if you don't need high framerate, to reduce power consumption.

The PC is still on, the monitors go to sleep. I don't really game anymore. Maybe 1-2hrs a week in the late evening on a weekend. Most of my work is RDP into a VM in a data center somewhere.

 

I was just wondering if there are any other metrics other than the max power consumption on the monitor that could affect heat output, or were there any OLED monitors that were designed specifically to draw less power and produce less heat as a feature.  There are so many monitors out there and the marketing makes it really confusing in general.

 

What I'm using now (LG 32GK650G-B, Acer XR382CQK) get pretty warm. I thought about just selling them and the PC and use a MacBook with a couple 15 watt monitors. My body will definitely be heating up the space more than the tech.

Meh, my room gets to like 30c or 90f or so easily, monitor won't help much. You know your body produces more heat just you being in the room. Get an AC like I did.

Some monitors can have power supply that is larger than what the monitor uses, so that isn't the best thing to look at. The average power use may be varying amount of lower than that.

 

In general:

* A human produce more heat than a monitor do, around 100-150w I believe.

* If you have lights that is still incandescent. Changing those out with for example led makes a larger difference than the monitors.

* Monitor that is in sleep usually draws minimally with power, should be counted as a non factor.

* Bigger and brighter monitors produce more heat. 

* I think VA produces more heat than IPS. And I think OLED produces less if you show a lot of dark content, but more when showing lots of white content. (From what I have read, correct me if wrong)

 

So if you compare and IPS monitor to another, I highly doubt brand or specific panel matters. If you really want to save power, turn down the brightness and put them to sleep. Or have fewer monitors, or cut power use elsewhere.
