Change, Dim brightness of laptop or computer monitor screen further

The best thing about using a Windows computer is that you can customize it or do almost anything – for free. I recently bought a new Dell XPS laptop. I was finding its screen a bit to bright for my liking, in spite of having reduced its Screen brightness to the minimum via the Power Options.

Change, dim, increase brightness in Windows

Normally one clicks the battery icon sitting in the notification area, selects  Adjust screen brightness and then moves the slider to the left to reduce the screen brightness.

In spite of having done this, I felt that the screen was too bright and I was getting slight headaches due to regular use. So I thought I had two option now – either get a shaded screen for the laptop or wear shades myself (just kidding) while working on the computer.

If you work at night with minimum ambient lightning in the room it could hurt your eyes. Looking around a bit, I came across two portable freeware which can help you dim your screen brightness further.

DimScreen lets you dim the whole screen. You can change the brightness easily in terms of percentage directly from the notification area by right-clicking on the program icon. You can get it here.

You can also dim or increase screen brightness by using hotkeys Ctrl+- and Ctrl++. You can also configure it further to suit your requirements via its Settings.

Dimmer is another such effective freeware. Once you set the brightness, you cannot change it easily by right-clicking the notification area program icon. You have to open its Settings. But both do the job well. You can download it here.

This is how your screen brightness would look if you were to reduce the brightness by 10-20%. Much cooler for the eyes, in my opinion!

If you want it to start everytime Windows starts, you can place its shortcut in the Startups folder situated at C:\ Users\ Yourname\ AppData\ Roaming\ Microsoft\ Windows\ Start Menu\ Programs.

You might also want to have a look at another freeware f.lux and SunsetScreen, which makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day.

    Great tip! When I am traveling, I typically keep my computer quite dim to save the battery. Do you know if DimScreen helps with to save even more battery? There are other times when I am watching a movie and the screen is still too dark even when it’s on the brightest level – this tool should help to solve that issue too!

  2. I do not think it saves battery …

    Having to work with a migraine, I started searching for a way to dim my screen more than the button on my monitor would allow. After reading about “DimScreen”, I gave it a try – 60% dim plus no lights on in the office – so much better! I highly recommend. And, thank you.

    it should revert back upon reboot, unless you chose the option to startup upon boot.

    Ctrl+- and Ctrl++ adjuster the screen size, not the brightness. It is at 100% and is hurting my eyes. HELP!
