To use these tools, simply install the software, launch it, and follow the on-screen instructions to calibrate your monitors. Once set up, you can adjust the brightness of all connected monitors simultaneously from the software's interface.

Night Light (Windows, macOS): Both Windows and macOS offer a 'Night Light' feature that adjusts the color temperature and brightness of your monitor to reduce eye strain in low-light conditions. To enable it, search for 'Night Light' in your OS's settings and follow the prompts.

Using Monitor Profiles

Many monitors allow you to save different brightness settings as profiles. This can be useful if you need to switch between different brightness levels for different tasks. To create a monitor profile, consult your monitor's user manual or search online for specific instructions for your model.

Once you've created your profiles, you can switch between them using the monitor's OSD menu or, in some cases, using a third-party software that supports profile switching.

In conclusion, changing the brightness on multiple monitors simultaneously can greatly enhance your multitasking experience. Whether you're using built-in OS features, monitor settings, or third-party software, there's a solution out there that fits your needs. So, go ahead and enjoy your perfectly calibrated, comfortable viewing environment!
