KVM usb switch?

Open vk496 opened this issue 2 years ago • 5 comments

Hello and thank you for this amazing project!

I have a S3423DWC monitor, which have KVM ability. From Windows, the DDPM tool allow switch the attached USBs to different inputs (when I use PIP/PBP). Is this possible to do with m1ddcl?

Let me know if I can do some tests/debugs to make that functionality possible.

BR, Valentin

If there are specific ddc commands for it then it can be implemented. I am not sure how well documented these commands are as this seems to be a highly vendor/model specific feature.

Any recomendations to sniff/inspect that? I can provide traces of the traffic and try to help implement this feature

Any further thought/progress on DDC commands for KVM? Would love this for using with Philips ultra wide in PBP

For anyone still looking for ddc commands I've documented some of them and the process of sniffing them out here https://github.com/ekamil/dell-ddc-documentation

Nice, thanks @ekamil!

Note: the latest BetterDisplay version allows adding custom DDC controls so you can also add these under the Hardware Control app menu and make them easily accessible via betterdisplaycli and shortcuts if you configure them so. If you let me know what configuration works best, I can even add them as display specific adaptations based on model/vendor IDs. I also plan on adding ways to export/import custom controls for easier deployment.
