No Stupid Questions

My understanding of your question makes me believe that you might be looking for a matrix switcher.

Basically, you have a bunch of inputs (devices) and a bunch of outputs (screens) and it allows you to select what goes where, eiyher one by one manually, or you can sace/load presets.

I've installed many of these on ships so that the skipper can easily select where he wants radar, autopilot, chart plotter, echosounder and whatnot, based on what he's doing .

The ones I installed were usually from Kramer, as they are pretty durable. I'm sure you can find cheaper ones.

You might be looking for a KVM not sure how those handle consoles though.

I've been in this situation for a few years now (Working from home, wanting to share screens between devices).

KVMs and HDMI Switches are what to look for, as others have said. Scenes aren't something you're going to get cheaply, but you've still got options. For reference, I currently have three 27in 1440p monitors.

The first one I bought was a cheap 2 HMDI IN->2 HDMI OUT that worked pretty well. It's straight 1-to-1 matching, you can't mix and match what goes where without actually moving the cables, but it was great for having my main and right monitor be easily switched between my Desktop and Work computers. My left monitor is just for my desktop so I can multitask.

It died after a couple years and I upgraded my main monitor to my first 1440p which it couldn't handle anyways. I wanted to use my main with Display Port so I got a 1 HDMI IN->2 HDMI OUT for just my right monitor. Center monitor has multiple inputs so I just use the screen's buttons to switch.

My current monitor setup I literally setup this week. Each has multiple HDMI and DP inputs and it takes just a few seconds to switch each one with its built in switcher, and I honestly think this is the way to go.

After a few years of doing it, I say if you are able to, prioritize nice monitors with multiple inputs and use their built in systems for switching. A few more button presses, but that's just a few seconds of time.

There are KVM switches that allow something closer to that at least, but usually only for 2 hosts (pcs). It stands for "keyboard, video, mouse" and they originated in the server space, but recently became common in the home/office as well.

They main purpose is to switch use of the monitors and any attached input devices between PCs. But there are models that allow mixed/shared use as well. If you're looking for one that supports 3 monitors and 3 hosts, with some splitting options, that might be harder to find or cost as rather pretty premium (hundreds).

There are KVMs that support signal switching. Probably about $3k USD.

They are largely employed in the camming industry, which is what I assume you are subtly mentioning you're going back to.

Not cheap. Have lots of problems, require an external remote to "switch scenes", and they fail...like a lot.

I couldn't suggest them unless you're fine throwing that kind of money away.
