I really wish some one made one of these as a DP 1.4 _matrix_ instead of a true KVM. 8in 8 out would be amazing
These exist, but are exceptionally niche, and very, extremely expensive.
You can do this with even less fiddling just by getting a KVM that supports video. There are reasonably priced ones that can even do 4K 60Hz. This also means you don't have to deal with monitors that don't implement input switching via DDC/CI (thanks LG).
it's much more reasonable and trivial on lower quality monitors but if one of the two PCs is for gaming you're going to want 4k at at least 120Hz which, last I checked, didn't exist (or was very expensive). You also might have a hard time finding one that takes DisplayPort in, which is preferable for Linux. Personally I just run the USB devices into a $5 USB A/B switch and manually change the inputs on the monitor.

Depends on what class of monitor you want to run it with. A KVM that can handle 4K 144hz VRR is... not cheap, if available at all.
> A KVM that can handle 4K 144hz VRR is... not cheap, if available at all It's supported by the relatively old HDMI 2.1/DisplayPort 1.4 standards - it shouldn't be that hard to find a KVM that can do this.
I'm not saying they don't exist, but all the ones I have tested that claim VRR support haven't actually supported Freesync/gsync in practice
If Steve Jobs herded makers of all the parts into a single room, and told them they aren't leaving until this takes 10 ms, I would be immensely grateful and I bet it could be resolved in a week.
I am trying to do the same, and I absolutely don't understand what is happening in the 3-5 seconds while two gigahertz-level machines and a modern monitor negotiate something over tens-gigabit-per-second connection.

What the devil is taking so long? I'm sure there's some technical reason that the check isn't more instant, but gosh it is frustrating every damned time.

I solved the multi-computer-to-multi-monitor problem with a Level1Techs KVM[1]. The price (~$500 for the variant I purchased) initially gave me pause, but the longer I've had it, the happier I am with my decision. It handles all the switching at the hardware level and thus has no perceptible lag for video or anything else. I'm able to connect a single set of peripherals, in my case, two monitors, a keyboard, a trackb…
I'm amazed that there's not more competition bringing the price down here.

The very fact that it is a tens-gigabit-per-second connection in an environment full of RF noise (we all love our high powered switching power supplies) makes it hard to get a reliable signal instantly. Still shouldn't take longer than a few hundred ms though (worst case).

When did KVM switches get so expensive? Level1Techs doesn't appear to be much more expensive than the competition, but the margin on all of these has to be absurd. They're not a particularly niche product and the BOM cost is only going to be $20 at most (a TMUXHS4612 is $1 for reference). I'm amazed that there's not more competition bringing the price down here.
