I now can use one windows computer and one linux computer without having to do very much to change .

You can't go wrong with ATEN KVMs. In hindsight I do wish I'd splurged for one with EDID support, but that's a minor nitpick and I don't switch machines frequently enough to really need it that much.

I'm using this to connect an ubuntu desktop with a lenovo laptop, using a logitech wireless keyboard / mouse. Connected everything and it worked right out of the box. Even the calculator button, the volume buttons, and the F-keys are working fine. Like many KVMs, the cables could be longer, and the USB cables dont need to be attached so closely to the monitor cables (my monitor input on the laptop is on a side w/ only one usb port, and so i needed to use a usb extension cable to connect the other usb).According to the manufacturer's info, this switch does NOT act as an emulator. I'm no expert on KVM, but the lack of emulation seems to be working just fine. Sometimes I just use one monitor and switch between computers, and my laptop keeps the proper resolution when I switch over to the desktop. I also sometimes use the laptop in a dual monitor setup, with the external monitor as either secondary or primary, and have had no problems switching back and forth. I have only had this for one day, so perhaps things will change over time, but been using it happily all day without a single issue. Only reason its not 5 stars is the cable length and the fact that they could easily make the USB connections unravel further so they could be more maneuverable. Solid overall.

I installed it, and it works just fine. Switches a VGA monitor, and a keyboard (USB) and a mouse(USB) at the press of a button.

Most KVM makers don't recommend or provide support for wireless keyboards and mice, but this works flawlessly in my application (Microsoft Sculpt Ergo Keyboard and a separate Logitech mouse that accompanies a keyboard/mouse combo set). I had trouble with one of my iogear KVM models that didn't support my wireless mouse and keyboard (the iogear KVM with a similar setup other one works fine). I didn't like the Logitech ergo keyboard so I switched to the Microsoft. Works flawlessly and put my challenges attempting to make the iogear one to rest.

I had ordered a cheap KVM switch for $18.99. I was disappointed the moment I set it up since it made the screen jittery so I returned it. So I decided to spend the extra $10 to get this one. Boy am I glad I did. This works great. No screen jitter, and it works exactly as they said it would. I highly recommend this KVM switch.

I am using the switch to share ONLY a monitor with two computers (not a mouse or a keyboard). When I followed the instructions, it appeared broken, so I requested a refund. As I was shopping around for a replacement, I learned that these (unpowered) switches like this one require electricity, WHICH THEY GET FROM THE USB CONNECTION TO A COMPUTER, which is why mine *seemed* dead. I plugged one of the USB cables from the switch to one of my computers and PRESTO! It all started working great. Refund: cancelled.

cost saving.
