Feature Request: DDC/CI Input Source Switching for MSI Modern MD271UL

[vincenzopiromalli]

Hi,

I'd like to request DDC/CI input source switching support for my monitor.

Monitor: MSI Modern MD271UL (4K UHD, 27")
Product page: https://it.msi.com/Business-Productivity-Monitor/Modern-MD271UL
Platform: macOS

Use case:
I have multiple devices connected to this monitor and would love to be able to switch inputs directly from BetterDisplay without using the monitor's physical buttons/OSD menu.

DDC/CI status:
The monitor supports DDC/CI (I can confirm brightness/contrast controls work). I'm specifically looking for VCP code 0x60 (Input Select) functionality.

Expected behavior:
A dropdown or button in BetterDisplay to switch between available input sources (HDMI 1, HDMI 2, USB-C, DisplayPort).

I understand this might depend on the monitor's DDC/CI implementation, but I wanted to submit this request in case it's something that could be added or is already in development.

Thanks for the amazing app!

Hmm. But this feature is already in the app. If you don't see it, then it might be that the display did not report this capability. In this case you can enable it under "Configure DDC Controls" and enable this:

You can customize inputs under "Input Sources..." and access the feature in the app menu under "Input Source".

Exactly same thing happening with the MSI Modern MD272UPHW - brightness etc do work, but NOT input source control, be it changing to HDMIs / DPs etc. even though I have HDMI connected to my other PC.
