Before Glimmr, adjusting my monitor's brightness was a daily hassle, especially when dealing with the tiny buttons on the back of my screen. Now, I can easily manage everything from my desktop. It's not just convenient; it's a relief.

Got questions?

We've got answers. Check out our frequently asked questions below.

How does it work?

expand_more

Glimmr simplifies brightness adjustment by directly interfacing with your monitors through DDC/CI. This provides the same outcome as using the built-in buttons on the monitor's back or sides, but with enhanced convenience and ease-of-use.

Can I adjust the brightness of individual monitors in a multi-monitor setup?

expand_more

Certainly! With Glimmr, you have the flexibility to adjust the brightness of individual monitors in a multi-monitor setup. The tool recognizes and allows you to control each connected monitor separately. This means you can fine-tune the brightness settings of each monitor independently, ensuring optimal visual experience and comfort across your entire multi-monitor configuration. Glimmr provides you with the granular control needed to tailor the brightness levels of each monitor to your specific preferences and requirements.

Can I set a global brightness level?

expand_more

Yes, you have the ability to set a global brightness level for all your monitors simultaneously with a single slider. This means you can adjust the brightness of all connected monitors at once, ensuring a uniform and consistent brightness experience across your entire display setup. It's a convenient feature that saves you time and effort, as you don't have to adjust each monitor individually.

Is the app compatible with all versions of Windows?

expand_more

Glimmr should run on all versions of Windows 7 and up, including Windows 8, 10, and 11.

Does the app work with monitors from different manufacturers?

expand_more

Absolutely! Glimmr utilizes DDC/CI to directly adjust brightness, ensuring compatibility with a wide range of monitors. In case you encounter flickering or consistent brightness levels, consider trying a different connection type (preferably direct instead of using adapters or USB-C hubs). Alternatively, you can utilize Shade Mode, which works seamlessly on all monitors regardless of the connection type.

What is Shade Mode?

expand_more

With a premium license, you can easily activate Shade Mode on any monitor. This feature enables you to adjust the brightness of your monitors by creating an Always-On-Top (AOT) semi-transparent window on the desired monitor. Please note that certain native Windows elements, such as the taskbar, may appear above this window when focused. Shade Mode is particularly useful if you frequently rely on adapters or USB-C hubs for monitor connections, encounter issues when adjusting brightness natively, or prefer setting your monitors to lower brightness levels than what they typically offer.

Can I schedule automatic brightness adjustments based on specific times of day?

expand_more

Absolutely! The scheduling feature allows you to create a custom brightness schedule tailored to your preferences. Simply specify the target monitors, desired times, and corresponding brightness levels, and Glimmr will automatically adjust the brightness of your monitors according to the schedule you've set. This enables you to have an optimized viewing experience at different times, without the need for manual adjustments.

Is the app compatible with both desktop and laptop computers?

expand_more

Yes, you can use Glimmr to adjust both internal and external monitors. It can also be used from a laptop or desktop, whichever you prefer.
