How Many Watts Does a Monitor Use?

Watt Consumption

Monitors show artistic content with their users. There clearly was numerous monitors you can purchase. It varies from sizes to models and manufacturers. Nevertheless, the more dilemma is its energy usage. 

Quick response

Power usage is afflicted with monitor size, model, and emitter. Moreover, it depends upon the construction, display brightness, and power-saving settings. Nevertheless, producer together with model kind make a difference. 

There are also several things you must understand in regards to the energy use of monitors which will fundamentally make lots of huge difference in whether or otherwise not you determine to choose one, particularly with regards to selecting one. To lessen the energy usage, you need to decide how much you’re currently eating. 

In this short article, we’ll offer an in-depth report on the energy use of various monitors. Firstly, we’ll glance at various kinds of monitors and their energy usage. Then we’ll illustrate different monitor modes that affect electricity consumption.

Types of Monitors

To get a sense of why some Computer monitors utilize more energy than the others, we’ll have actually to take into account the product they have been created from. Listed here are 4 kinds of monitors.

CRT Monitors

CRT or Cathode Ray Tube monitors are huge and cumbersome in proportions. They’re made from vacuum pressure pipe with heaters, circuits, and electron firearms. They’re no more utilized due to their energy usage and production expenses. The typical energy use of an average 19-inch display is mostly about 100 watts

LCD (fluid Crystal Display) Monitors

LCD monitors will be the hottest variety of monitor. These monitors utilize transparent electrodes and polarizing filters. Additionally, these monitors offer higher quality and are also easier to produce. In addition, they have been slim and light. Ergo, the typical energy usage with this variety of monitor is all about 22 watts for a 19-inch display. 

LED (Light Emitting Diode) Monitors

LED monitors will be the most advanced technology available in the market. Much like LCD, LED monitors will also be flat and slim. Nevertheless, it is composed of a somewhat curved display that makes use of Light-emitting Diode technology. They eat less energy than LCD and CRT monitors. For an average 19-inch display, the energy usage is mostly about 20 watts

Plasma Monitor

As compared to Light-emitting Diode and LCD, Plasma monitors use gas-filled technology. The gas-filled cells are positioned between two synchronous cup areas, plus the display lights up with the aid of ultraviolet radiation. Nevertheless, they have been alot more high priced than LCD and LED monitors. For a 19-inch display, the energy use is about 38 watts

Operating Modes of Monitors

The range watts a monitor utilizes additionally depends upon its working mode. You can find an overall total of three modes that the average monitor has. Nevertheless, remember that the energy usage can vary greatly with regards to the model together with maker. Let’s look at the 3 working modes. 

  1. Active Mode: Active Mode refers towards the complete load in the monitor. Or in other words, the monitor is on and functioning
  2. Standby Mode: This mode decreases its energy usage to save lots of power. A monitor frequently goes into this mode after 20-30 moments of no task
  3. Shutdown Mode: In this mode, the monitor is off aside from its energy light. Just the red LED light seems, showing it really is in Shutdown Mode. Nevertheless, it nevertheless uses between 0 to 5 watts until you pull the plug on the energy supply. 

Now that we’re acquainted with the monitor technology as well as its energy use, let’s take a good look at the ultimate summary regarding the energy use of every type of monitor.

Monitor Screen Size CRT LCD LED Plasma
19 ins 80 watts 22 watts 20 watts N/A
20 ins 90  watts 26 watts 24 watts N/A
21 ins 100 watts 30 watts 26 watts N/A
22 ins 110 watts 40 watts 30 watts N/A
24 ins 120 watts 50 watts 40 watts N/A
30 ins N/A 60 watts 50 watts 150 watts
32 ins N/A 70 watts 55 watts 160 watts
37 ins N/A 80 watts 60 watts 180 watts
42 ins N/A 120 watts 80 watts 220 watts
50 ins N/A 150 watts 100 watts 300 watts

Keep in your mind

Just understand that these energy usages can vary greatly somewhat. These estimations are normal, plus some monitors could cost you more with regards to energy usage based on your location and electricity device each hour


And that’s a wrap. This article has supplied a short guide on what numerous watts a monitor utilizes. So long as you keep your monitor on standby, you aren’t eating much energy in comparison to other home gear. Furthermore, you are able to save your self much more by repairing the heating, cooling, and lighting problems with your monitor. 

Frequently expected concerns

How much energy does a monitor use within rest Mode?

Monitors typically use 5 to 10 watts when they’re in rest Mode. Even though dimensions are normal, they could digest more energy. Nevertheless, they won’t digest a lot more than the limitation.
