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.

How many Macs can I run this on?

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

Are Apple Silicon Macs supported?

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

Note: DDC on the HDMI port in Apple Silicon Macs doesn't work yet, because it doesn't forward DDC commands to the display for a currently unknown reason. Displays connected to the Thunderbolt / USB 4 ports work fine with DDC.

How can I download the latest version?

You can click the settings icon in the bottom right of DisplayBuddy and select "Check for Updates" to automatically get the latest version. You can also get the latest version of DisplayBuddy here.

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 without physically touching the buttons on my monitor at all.

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. You can find more troubleshooting steps here.

Is there a Windows app?

I haven't made DisplayBuddy for Windows yet, but Monitorian is a good alternative available on the Windows store.

I lost my license key, how can I recover it?

No worries, you can look for an email from Gumroad in your mailbox to find your original license key. If you can't find the email, just contact me at support@displaybuddy.app and I'll help you out.
