display-switch VS ddcutil

I’ve been using display-switch[0] for this for a while now. No problems whatsoever. Works on windows/mac/linux.

Now it just need to be combined with something like https://github.com/haimgel/display-switch to do a DDC/CI monitor input switch as the USB activity moves around.

With a device like this you'd be missing the on_usb_connect event, but presumably you could do something (a special HID device button, an extra device id appearing, who knows) to make it work.

The best option I've found is to hook both computers up to a USB-only KVM, and plug them in via separate video cables to the monitor. Then set up the computers to tell the monitor to change inputs (via DDC commands, which most but not all monitors support) when you change devices on the KVM

There's software to help do this automatically (https://github.com/haimgel/display-switch)

Cynical footnote: PC users can continue to enjoy https://github.com/haimgel/display-switch while Mac users need to buy a 300 USD device. That's the Mac experience for you :D

There's a workaround in https://github.com/haimgel/display-switch now for M1 Macs. In general, you made your bed by buying a Mac, sleep in it.

Oops I missed that https://github.com/haimgel/display-switch

Then we will run https://github.com/haimgel/display-switch to have the monitors switch inputs when you use the USB switch.

Apologies. I hate when people do that as well.

In addition to the other links posted, ddcutil.org has some more good info: https://www.ddcutil.com/#introduction

Sous Linux j'avais utilisé ddcutil

Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

ddcutil (a command-line tool, and what most UI tools are based on)

A related non rust tool (that also has an optional GUI) is ddcutil. How does this compare to that?

I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.
