Questions? Answers.

Will it work with my display?

DisplayBuddy talks to your monitor using the DDC spec. If you've a monitor that was manufactured in the last 5 years or so, there's a very high chance it will work great with DisplayBuddy!

If by chance it doesn't work, we'll refund your DisplayBuddy purchase within 7 days of your order.

Do you offer a free trial?

No, but we will give you a refund for your app purchase within 7 days if the app doesn't work for you.

How many Macs can I run this on?

Your license is valid for use on upto 4 Macs you own.

Are Apple Silicon (M1) Macs supported?

Yes, Apple Silicon (M1) Macs are fully supported, and can control external display brightness, constrast and volume using DDC.

Note: The M1 Mac Mini's HDMI port does not work yet, because it doesn't forward DDC commands to the display for a currently unknown reason. The Thunderbolt / USB 4 ports on the M1 Mac Mini work just fine.

Why would I need something like this?

I sometimes work during the night, and I don't want my two monitors at full blast hurting my eyes in dim light. I use DisplayBuddy to quickly switch my displays to the correct brightness based on the time of the day.

It's not working for my monitor!

A lot of monitors have built-in presets for brightness and contrast, like Game, Movie, Reading etc, which lock your monitor's brightness & contrast to predefined levels. I highly recommend you set this mode to Custom, so that DisplayBuddy can then control these values.

Some monitors also have a DDC/CI setting: make sure this is set to enabled.

Is there a Windows app?

I haven't made DisplayBuddy for Windows yet, but there are some alternatives available.
