Top Laptop PWM Ranking (Rated by negative impact on eyesight)

on

Users should pay a lot more attention to PWM, or Pulse-Width Modulation, when buying a new laptop. Why? Because many of us work with our computers for hours every day, and PWM is one of the things that have negative impact on our eyesight.

Pulse Width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye – our brain make us think that the display in front of us isn’t flickering, but just has lower brightness instead. Staring at aggressive pulsations could easily give you headaches or eye strain, and we’re convinced that nearly everyone has experienced that.

That’s why we test every laptop in our laboratory with high-efficiency equipment in order to determine the exact frequency and structure of the light impulses. The results go through our algorithm and we present you with a final rating for each of them in the list below. You can find out more about PWM in our dedicated article on the matter, or you could just make your conclusions based on our final rating.

  1. Is Iris program good for this flickering problem?
    I have a laptop (Dell Xps 13 9343) and it has PWM.

    Using Iris, my eyes feel better in a warmer mode.

    Thank’s a lot

      1. I have the DELL XPS 13 9350 and have some eye issues because of the screen. What is this Iris you are talking about?

        1. Well it makes your monitor better for your eyes. I have write a lot of articles on the home page about what it does.
          PWM flicker brightness , blue light reduction and etc.

          1. Thanks Daniel, but is this is like a programm I can download? If so, could you please provide me with the link?

  2. Okay, found it already. So does simply donwloading and running IRIS light reduce eye problems? Or how would I have to adjust the settings to do so?
