IOGEAR 2-Port USB VGA Miniview Micro Cabled KVM Switch - 2048 x 1536 - Hot Keys Switch - w/Audio - Plug n Play - PC, MAC, SUN - GCS632U

I DO highly recommend this item, but with caveats, know that there will be a delay with USB over the older PS/2 Mouse/Keyboard iogear which would toggle instantly.Pros:--Does what it is suppose to--pulls power from the USB cables plugged into the machines(so no need for additional power)--double tap of Scroll Lock to toggle--Able to use USB Hub with this, so you can toggle many usb devices at once--Do not need to use VGA video toggling if working with laptop or working on a pc/server you don't need a monitor attached to.--I only used the USB toggle portion of this device, and that ability is great to have(Have old PS/2 version and used it fully for keyboard/video/mouse(where the name KVM comes from) toggle, and it is great for that, but the ability to be able to choose what you want to have connected and toggled is really adaptable and useful for 'odd' configurations you might need to fit into your setup.)Cons:--My Logitech K350 wireless Keyboard doesn't have a physical 'Scroll lock' key and made me need a 2nd old 104-style usb keyboard plugged in just for allowing toggle. (I found that it DOES have the key, but I don't have the KVM setup right now, nor have time to play with it to test it (FN+Pause/break, for those who are curious...), more on this below in Add. Thoughts)Other thoughts:I had the old IOGear mouse/keyboard version of this and have used it for years, and it is greatI only bought this USB version for when my laptop keyboard died, and I was waiting for a cheap replacement to get sent from China (worked out well for me) A KVM like this is really nice to have just 'laying around' for when you need to work on a second computer, which is why I bought it.Even having to use the 2nd keyboard just sitting on the far side of my desk to toggle PC i was controlling, it was a god-send for when I needed a KVM like this, to allow me to use my keyboard on my laptop and my desktop at the same time. (the delay of switching to windows was ~10 seconds for me, but Linux recognized it instantly it and used it smoothly.) I was under a lot of time/pressure constraints when I need this, so I didn't have time to 'fix' things that weren't 100% perfect, but I bet my issues were because of the VERY convoluted setup I needed (wireless keyboard/mouse, USB mass storage, USB HUB with both of those plugged into it, and then audio no used at all from KVM,) (The semester ending, and deadlines for projects made this the very best solution I could hope for when I needed it.)I used this for input toggle only, not output (laptop had working monitor) And VGA really isn't that useful on a modern PC/monitor, BUT, its a great legacy input, so I plan on setting this up as an alternate input for my PC when I need to help someone with their PC.Without even looking I know there are DVI KVMs, and probably HDMI/USB3/DisplayPort ones coming or out already, and those might better fit your need. And those solutions might fit your need better. But this device fit perfectly for what I needed, and might fit your needs.If you ONLY need USB toggle, and NEVER need audio or video, then a USB push toggle device can be had for ~10$ and is nice to have also. (Using both together to allow you to toggle USB mass storage separately from the keyboard/mouse (and if you want audio/video) is what I ended up using and it saved me hours and hours of plugging in and unplugging cables into/out of laptop/PC, and that alone was worth 2x the price I paid for this the USB switch combined)</Rambling response to try and help explain all the possible Point of Views that this needs to be approached from.>

I spent many hours researching KVM switches to find one that satisfactorily switched between older PCs using Windows XP Home and a new PC running Windows 7 (64 bit). Essentially every one worked well with the older PC, but needed to have the monitor reset when switched to the Windows 7 PC. This unit advertised it would do this flawlessly. It actually does.All the equipment needed to connect the PCs to a single monitor are included in the package. Setup is relatively easy with picture directions, as well as written ones to guide you to make sure all connections are correct. There is sufficient cord length from the unit to have PCs about 6 ft away. One word of caution - connections between the unit, PCs and monitor are made through VGA connections, not DVI.During installation, I was unable to get the system to work properly. I was using the new keyboard, optical mouse connected to the unit through the USB connections. A phone call to the IOGEAR help line connected me to a most helpful tech representative. After making sure all the connections were properly done, the problem turned out to be "user error" by my failure to note the difference between the new keyboard and the old one. Once my training was updated, everything worked beautifully. There is no problem when going back and forth to the Windows 7 unit with the 20 inch widescreen monitor - no change in the settings. The only issue with the old Windows XP Home PC and the switch is the resolution of the PC is limited by the graphics card and not the switch. Still the slightly stretched view is perfectly satisfactory for any of our use of that machine. For sound reproduction from either of he PCs, I used only the connection provided with the switch and the sound through the monitor speakers is extremely satisfactory for my usage.From my experience, I can heartily recommend this inexpensive method to maintain quick access to data and files on an old Windows computer, while working with your new updated Windows 7 machine.
