ddccontrol VS display-switch

Why do they not allow doing the same for external monitors using DDC? There are several apps that do just that.

Try ddccontrol on Linux or https://www.nirsoft.net/utils/control_my_monitor.html on Windows.

ddccontrol and gddcontrol works well

If I were you, I would take a look at ddccontrol. It's a utility that allows you to query the state and send commands to your monitor via the command line. I currently use it to increase / decrease the brightness of my monitor depending on the time of day.

i have always hated having to fiddle with the buttons on the back of my monitor to change things such as the brightness but now i have finally found a better way https://github.com/ddccontrol/ddccontrol

Before I look into automating it, I wanted to get it working first. For this, I have a tool called ddccontrol (https://github.com/ddccontrol/ddccontrol). But this needs root privileges. So I'm just wondering if there are other ways, since I couldn't find any.

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.
