    If Brightness Isn't Changing

    Follow these steps to ensure DisplayBuddy can communicate with your monitor

    1. Enable DDC/CI on Your Monitor

    Most monitors have DDC/CI disabled by default. You need to enable it in your monitor's OSD (On-Screen Display) menu.

    • Press your monitor's physical menu button
    • Navigate to Settings → DDC/CI or System → DDC/CI
    • Enable DDC/CI (sometimes called "External Control")
    • Save and exit the menu

    2. Use the Correct Cable

    DDC/CI requires a digital connection that supports bidirectional communication.

    • ✅ Works: HDMI, DisplayPort, USB-C/Thunderbolt
    • ❌ Doesn't work: VGA, DVI (in most cases)
    • Try a different cable if brightness control isn't working

    3. Disable HDR (If Enabled)

    Windows HDR can sometimes interfere with DDC/CI brightness control.

    • Open Windows Settings → System → Display
    • Select your monitor
    • Turn off "Use HDR" if it's enabled
    • Restart DisplayBuddy

    Still Not Working?

    Some monitors don't support DDC/CI or have limited support. Here's what to check:

    • Check if your monitor model supports DDC/CI (search online)
    • Try restarting both your computer and monitor
    • Update your graphics card drivers
    • Contact us at [email protected] for help
