To understand why some PC monitors of the same dimensions consume more power, while some monitors consume less power, we need to consider the materials from which they are made. Types of Monitors And Their Power Consumption If you want to know How Much Power Does a Computer Use in Sleep Mode, read this article. With sleep mode, you can save up to 70% of energy. Although some monitors may consume a little more power, but it’s all within normal limits, so you don’t have to worry about that. This is the average estimation we took according to the Energy Department. *Keep in mind that results may vary significantly How Much Power Does a Monitor Use in Sleep Mode?ĭesktop monitors during the sleep mode use between 5 to 10 watts of power, while the laptop monitor uses about 2 watts. The older LCD monitors were using the CCFL ( cold cathode fluorescent) technology that mostly gives 20 to 30% less power when we compare it to LED and LCD displays. Keep in mind that LCD & LED monitors use the same TFT ( thin-film transistor) LCD technology to display images on the screen. Power Consumption of Computer Monitors by Screen Size However, there can be major differences depending on the manufacturer and monitor model. Ultimately, keep in mind that this estimation can be higher or lower, in each case.
In some countries, the price may be more than 0.13 cents per kWh, and more powerful monitors require even more energy. $45 per year may seem like a small figure to someone, but it’s important to remember that this is only an estimate.

If you are looking to buy new PC monitor, this is the model we recommend, Acer SB220Q bi 21.5-Inches Full HD. Now, let’s assume that your monitor is turned on and it consumes 40 watts per hour, 24 hours a day, 7 days a week, 365 days a year. At a cost of about 0.13 cents per kWh, the monitor increases the electricity bill by $45 every year.
The power consumption of any computer monitor varies mostly on the display technology that is used, the screen size, the build quality, brightness of the screen, what is shown on the display, and on the saving settings. If you use a typical 21-inch monitor for 3 hours per day, you will consume between 0.3 kWh which is around 0.01 cents per day. Things that affect the power consumption of a monitor is its screen size, model, and what is emitted on it. So How Much Power (Watts) Does a Monitor Use? Typically desktop monitors consume between 20 to 100 watts of power. How Much Power (Watts) Does a Computer Monitor Use?
