Which Monitor Is The Most Energy Efficient? (Answered)

Most of us use a monitor and PC virtually every day. Whether this is for working or simply playing a few games. If you are looking at the global energy situation, it is easy to see why using energy-efficient products might be one thing for you to consider. Each monitor is designed to use power, but which one is the most energy efficient?

Any monitor with an “A” on the label next to energy usage is considered to be the most efficient.

While we cannot pinpoint one specific monitor, you will find numerous options that have this solid energy rating. You must consider one of these monitors when buying one and save energy. The main aim of this article is to look closer at these energy labels and help you understand what to look for when buying an energy-efficient monitor.

What Does The Energy Rating On My Monitor Mean?

Almost all monitors nowadays are subject to an energy rating, which is often indicated on the label. You must have a basic grasp of what these energy labels mean before buying one. You are bound to find one of the following letters somewhere on the label of the monitor to show the energy efficiency:

  • A Label: The most energy-efficient monitors will often have this label.
  • B/C Label: The B and C labels are still great options and are considered to be “energy efficient”.
  • D Label: The D label is slowly phasing out amongst monitors and is only considered “average”.
  • E/F/G Label: The worst monitors you can buy in terms of energy efficiency would be these monitors.

Determining the energy efficiency of a monitor is one of the hardest things to do for manufacturers and the screen size is often combined with the power consumption to give a rating. For instance, a 27-inch monitor might be using more energy than a 24-inch monitor might, but the 27-inch monitor has a better rating.

Regulators would look at the ‘kilowatts per hour, while including the screen size, with the knowledge that bigger screen size is bound to use more energy, regardless of the power settings. The active power, which is measured in watts is also one of the considerations.

It is invaluable to use a monitor with better energy efficiency, as this will make it much easier for you to save some power, while also having a good gaming experience. Smaller factors like input and brightness might also bump up the energy consumption of your monitor.


Saving on your power bill is important in the modern era and while this is one of the hardest things you can do, your monitor might be one thing that can help you. We would recommend looking for any monitor with an A on the label, which ensures better energy efficiency.
