display-switch

I have resorted to using separate physical computers + vlan network separation when exploring untrusted AI workloads. Yes, it costs, but so does a breach. Thanks for raising this aspect. Btw https://github.com/haimgel/display-switch helps a lot.

You can avoid the kvm with a cheap USB switch and software. https://github.com/haimgel/display-switch

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

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.

https://github.com/haimgel/display-switch might be a piece of what you need to get this working.

Adding to this: search for haimgel/Display-Switch[1] on GitHub, which can switch monitor inputs using DDC commands on USB connect/disconnect events. Poor man's KVM :-) [1] https://github.com/haimgel/display-switch

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)

I have the same setup and use the following software to send the switch signal to the monitor. https://github.com/haimgel/display-switch

I have a lo-fi version of this using a 4port usb-switcher and display-switch [0] [0] https://github.com/haimgel/display-switch The only thing you’d need to figure out is the standing desk part. My usb switch came with a wireless controller which is the main way I interact with it.

I have a personal computer, a work computer and a gaming computer and I switch between them using an Aten USB switch [1] and this software that switches monitor inputs when your plug/unplug USB devices [2]. Works quite well and costs less than 50€. [1] https://www.amazon.de/dp/B00B1SENTE/ [2] https://github.com/haimgel/display-switch

In conjunction with a KVM for switching the USB between devices, you can use this software to automatically swap the inputs on the monitor (if your monitors support the command protocol, most do but one of mine doesn't support the "change input" instruction): https://github.com/haimgel/display-switch Otherwise you'd need a KVM that supports 3 monitors which I'd imagine is a compatibility nightmare if they're beyond 1080p@60hz

I do the same thing (plug both computers directly into different inputs on the monitor but use a USB switch to switch the mouse & keyboard). If you install this software on both computers, you can eliminate the "switching via OSD" step, because it will watch for the USB connect / disconnect events and initiate the input switch automatically via the DDC connection to the monitors, so it gives you true one-touch KVM switching at the cost of a USB switch. This works especially well in cases where an actual KVM switch would be expensive or unavailable (in my case, I'm switching three 4K HDR DisplayPort monitors, which would require a very expensive KVM switch). https://github.com/haimgel/display-switch

As someone who is using display-switch[0] to imitate a hardware KVM switch in software I can say I’ve seen many of these issues in trying to debug the random issues that using ddc creates. Ddc is to http what your county clerk’s website is to (current) healthcare.gov essentially. There’s no standardization at all, it’s maintained by 1000 different people who don’t communicate and don’t care how anyone else is doing it because only like 1/10000 people have heard of it and 1/100000 uses it.
