I currently have three systems: XP, a laptop with Windows 7, and Windows 10. This KVM is expensive for me and I've thought twice about buying it, but I'm so glad I did. I can switch between my systems without losing video resolution. My Windows 10 systems didn't have an HDMI video port, so I just plugged a separate VGA cable into the back of the monitor until I got a new graphics card for it. I can still use the same keyboard and mouse just by changing the input on my monitor. Only my laptop uses both monitors, other systems only use one and this KVM has no problem with that.
