This will also block some UV and blue light if you don't want to use software or use some strange Linux on which no software works at all :) Technically you can also lower the brightness by wearing sunglasses in front of the PC. Most LED monitors change the brightness via a process called Pulse-width modulation which is really bad for the eyes. One thing to note is that I don't recommend changing the brightness via monitor buttons if the monitor is LED. Iris can do this also but this is not related to the question. One plus of Iris over f.lux is that you automate the brightness reduction based on day and night just like most blue light filter programs do with the color temperature and blue light. Iris and f.lux should work fine because they change the white point of the screen which is better. This method reduces contrast quite a bit and may cause eye problems. Looking at the other answers most programs lower the brightness by placing a transparent overlay filter. This over the maximum brightness is really useful when watching movies for me Here is how brightness on 110% looks like You can go as low as 10% if you enable Extended values, but this is really dark screenĪside from going down you can also go up to 150% brightness. If you set Iris to 50% brightness the screen will look like this Here is a normal screen with Brightness on 100%

Click here for more info.You can get the biggest possible dim range with Iris. You should now have access to your full brightness on your windows 10 installation. For those that like their screens bright, I also recommend checking out the f.lux application, which makes bright screens more tolerable by adapting the tint to be easier on the eyes based on the time of day. Changing the option to “off” restored full brightness for me.Īnd there you go. You will see two options, one for while the computer is plugged in, and the other for while it is on battery.Expand the “Enable Adaptive Brightness” node by again, clicking on the + to the left.Find the Display node on the page and expand it by clicking the plus sign to the left of the word “Display”. The “Power Options” windows should open.Click the “Change Advanced Power Settings” link on the page.A link should appear in the results which will take you to the power plan options. Click the start button and search for “edit power plan”.

Turns out that there is a power-saving feature called “adaptive brightness” which is the cause of this lack of brightness.

I recently installed Windows 10 on my macbook and found that the brightness wasn’t that bright. Just a quick tip for those running Windows 10 through bootcamp (and maybe even those running a non-apple laptop/desktop).
