  1. does ClickMonitorDDC (ddc/ci) work on AMD video cards?


    just went from a gtx 1060 to AMD a vega 56 and all of a sudden i cant use any of my ddc/ci features anymore. i even tried other apps and all they say is that they dont detect a ddc/ci monitor when my monitor defiantly is and was working fine. and regardless of the setting on the monitor it still dosent work anymore.

    DDC/CI and brightness keys

    Thanks for the reply, but your answer is not clear.

    I understand that the graphics card is ultimately responsible for sending the required signal.

    But the Dell Display Monitor software already allows software driven control of the screen brightness (via an onscreen slider), suggesting that the graphics card is already behaving as expected. The user manual of the graphics card offers no further advice
    about setup of this function.

    My question is really more about the Microsoft Modern Keyboard. The support page you linked to gives no information about the specific functioning of the media, volume and brightness keys on the Modern Keyboard.

    With a fresh install of Windows 10 Pro 64-bit, a 2017 DDC/CI compatible monitor, and latest generation graphics card, I would have expected this Modern Keyboard function to "just work."

    But since that is not the case, I would be very grateful if someone could suggest a way to get these elements working together as expected.

    Thanks!

    DDC/CI and brightness keys

    I have a Dell monitor supporting DDC/CI, a Intel-based PC running Windows 10 Pro 64-bit with an Nvidia GTX 1080 Ti, and a new Microsoft Modern Keyboard with Fingerprint ID.

    The Modern Keyboard has brightness keys (top middle, also F7/F8 if you hold down "fn"), and the monitor can accept brightness changes via DDC/CI (works with the Dell Display Manager software). When I touch the brightness keys, I get a small overlay in the screen
    top left of the brightness "changing" (is this a Windows overlay), but the actual display brightness does not change.

    Is there a way to get the brightness keys working to change the monitor brightness?

    Whose technology is responsible for this? Nvidia? Microsoft? Dell?

    does ClickMonitorDDC (ddc/ci) work on AMD video cards?

    DDC/CI and brightness keys

    From Dell: "The Dell monitor team never tested the "Microsoft Modern Keyboard with Fingerprint ID" and its software. You should start by searching for Microsoft support."

    From Nvidia: "Microsoft is in charge of display brightness as of Windows 10."

    From Microsoft: "adjusting the display brightness using the keyboard keys is controlled by the graphics card installed on your device. …we suggest that you refer to the user guide of your graphics card."

    From EVGA: "I'd say Dell."
