One of the big remaining users of display switching is the military. When something important is happening on one screen, others need to look at that screen. The military wants switching so they don't get everybody jammed around the screen with the action and abandoning their own stations. Here's the current incarnation of NORAD HQ in Cheyenne Mountain.[1]

Such switching goes all the way back to NASA during Apollo. Their system put all the screens on a video cable as cable TV signals. Each console, and other locations around Mission Control and Launch Control, all had channel selectors and could watch any display. Using different technology, that capability was maintained in later control centers.

My monitor has a KVM built in... http://www.dell.com/en-us/work/shop/dell-34-ultrasharp-curve... It has two USB ports that can go to two different computers, and then in the settings you can set it up so that when you switch from one input to another it also switches what the USB devices are connected to. There are 4 USB ports total on the monitor, and they switch from one device to the other. It's great, instead of…

well this monitor also can daisy chain another monitor. which is awesome per se, and actually the daisy chained monitor gets switched aswell. (http://en.community.dell.com/support-forums/peripherals/f/35...)

but 800 bucks for a monitor :/ I've always looked at these dell monitors. but I never use a external monitor when I'm at home (laptop). But at work my boss would never pay for any of those.

Earlier quoted context omitted.

Partner can be used in lieu of spouse for an unmarried couple.

Even for married couples!

Thanks for the pointer. I wasn't happy with my phrasing. I should have just referenced a dictionary. MW's sense d is what I intended to convey:

> "a person with whom one shares an intimate relationship : one member of a couple"

PSA: It's about this "KVM": https://en.wikipedia.org/wiki/KVM_switch Not this: https://en.wikipedia.org/wiki/Kernel-based_Virtual_Machine

I could never understand why the makers of KVM the virtual machine thing didn't realize they had overloaded an acronym. It isn't as if they weren't likely to have come across KVMs in their work. Were they non-native-English speakers perhaps?

Software devs aren't sysadmins, I imagine most of the people involved here never have been responsible for actual production physical servers before and never had to use one.

Are there any not-too-expensive, modern (as in DisplayPort-friendly and USB), hardware KVMs available these days?

I started looking into a solution and I ended up shelling out money for Synergy, which was cheaper than the HDMI-or-Displayport-I-forgot KVMs I saw on Amazon, which looked like they were in the 2,300+ range (and with really poor reviews).

What I miss about KVM switch is the ability to switch to another system using a keyboard hotkey, such as double-pressing the "Scroll Lock" key on the keyboard. Most high-end KVM had this feature, so that I could use a hotkey to quickly switch to different system. Once anyone gets used to this, there's no going back to rotary dials or slow physical push buttons, etc. I had 3 or 4 systems connected to KVM and nothing was faster.

I've tried using modern HDMI/monitor switchbox/splitter and USB switches, but they require awkward physical reaching for the buttons, as I have to reach out for a button or two, every time I need to switch to another system. The old KVM did this in split second and I didn't even have to think about it, sort of like Vim once you get used to the keys. I was able to work so much faster, switching from one system to another, whenever I needed to. Now, I have to think about it before switching, not that I'm lazy, but I don't want to exert so much energy just to switch to another system.

Edit: I also miss PS/2 and VGA, for their ability to switch quickly as well. USB devices and HDMI monitors take awhile to switch.

I've never really understood the desire to use the button on the display to turn off monitors - does allowing the monitors to be switched off by the OS not solve basically the same problem ?

I leave my PC running 24/7 pretty much, so at night I want the monitors turned off so it doesn't illuminate the whole living room (which I can see from the bedroom - it is a small apartment). I used to turn them off with the button on the monitor (when all my monitors were DVI), so if the mouse was moved by accident during the night it wouldn't wake the monitors up. Right now I have to let it go to sleep normally, an…

Just leave your mouse upside down.
