Pros: works great, didn't have to purchase cables to connect the switch, it has everything you need.

Cons: none

Pros: This is the 3rd one I am using and have no problem with any. Basic plug and play. I have 14 pc's and all are on IOGEAR KVM's.

Cons: No audio port. Not really a con as most speakers are USB. It can be resolved easily.

Other Thoughts: I tried the KVM with audio and had major issues with connectivity. I sent it back. I know now I should have stayed with a known product.

Pros: I found this at the Goodwill Store, so any defects are obviously not covered by any warranty. With that said, this device works very well, however I read another review about EDID, not sure what that is, but it really seems to be part of my problem.

Back to Pro's: This has supported resolutions as high as I can use, I don't think I've used anything over 1600x1200 yet. I personally use a USB hub on my keyboard and mouse end, sharing a thumb drive on the 2nd USB. That all works flawlessly (I doubt that is the intended use, but hey it works)! I use Logitech keyboard and mouse, and I have had 0 issues with detection on any machine for input devices, even with the thumb drive being KVM'd.

Cons: The Video EDID is apparently a problem I am having. I hope the review I read labelled this issue correctly with EDID, as I'm about to google it myself. I use my Windows 7 Ultimate with a GeForce 560TI and switch to my old PC which runs a GeForce 8400GS on Vista Ultimate. Upon using my new machine and leaving the old machine on to run background downloading, or burning to keep it in use as it's setup to do what I want, and the New PC isn't really ready for full change. Anyways, I switch back to the old PC and I'm stuck at 640x480 resolution... It usually takes a reboot, or this time I've goofed around for nearly 30 min and finally got it to normal resolution. I am trying to update my Monitor drivers and video card drivers now, maybe this will help I hope!

Other Thoughts: Any input on how to resolve this would greatly be appreciated. I think I provided enough info for any halfway decent company could resolve this issue... If it is a fixable issue, provided the hardware just may not function in a way to resolve this odd situation. Either way, a response would be respectful to those other customers looking to find a solution later down the road!

And by no means am I disappointed after paying less than $10 for this used! I would be very pleased if there was a fix for my issue at hand, also I have tried without the thumbdrive, and used the other 2 wiring harnesses. It seems to be some hardware in the KVM loses sync with the pc that is inactive. I have a few other ideas, for instance, turning off the screen saver I think may help, but I didn't want to burn in my screen if I had to leave for work and come home to find I forgot which PC I was on. Maybe this could be a BIOS setting? For the S1, S3, or any other settings available for this. Hopefully someone will find this info useful, and if nothing else we (consumers) can resolve the issue together if IOGear won't chime in.

Pros: It works between two desktops, a server, and a Raspberry Pi.

Cons: None.

Pros: Works with every machine I throw at it.

Compatible with DVI-I to VGA adapters

Cons: None that come to mind.

Other Thoughts: I work in a computer repair shop and bought this to replace a PS2/VGA switchbox.

It's been about a month now and I haven't run into any problems switching between the variety of machines that come through the shop.

Pros: Works as advertised.

Cons: Sometimes a little lag switching screens, the keyboard and mouse do not always pick up right away.

Pros: I ordered this so that I could use my Mac, Linux, and Windows box on the same KVM. It worked fine for Mac and Windows, but it wouldn't regain the keyboard and mouse when going back to Linux (Ubuntu).

Cons: It wouldn't regain the keyboard and mouse when going back to Linux (Ubuntu).

Other Thoughts: I wouldn't recommend this to someone using Ubuntu. I'm not sure if all distro's would act the same way. My experience was not great. I switched back to a IOGear 2 port USB KVM that I was using before. It works fine.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for your experience. Linux will sometimes require additional drivers for your keyboard, mouse or video connection. The GCS22U is compatible with Linux. Once again, thank you for choosing IOGEAR.

Pros: Simple installation, quick response when switching between computers, easy to use.

Cons: None that I have run in to

Other Thoughts: I have this installed with two rack-mounted servers running Server 2012 and another PC running Win7 Pro. I did not power anything down to install the KVM switch. All machines recognized the keyboard and mouse without a problem. The actual device is large enough that you can use a label maker to print off labels for what machines are connected to which ports. I'm getting ready to order a second one for use in another office.

Pros: Separate button for swiching

Cons: 2 USB plugs per cable. Why 2?
Short in video cable on one port, Failure out of the box

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The reason for two USB connections on the KVM cable is one USB connection is for the mouse and keyboard, the other connection is to power the GCS24U. Since the unit is backed by IOGEAR's 3 year warranty feel free to contact our customer support at 1-866-946-4327 or email us: support@iogear.com. Again, thank you for choosing IOGEAR.

Pros: This does everything I expect a KVM switch to do.

Cons: But I bought this specific switch to get me to higher resolutions I.E. 2048 x 1536. Instead the highest Width I get is 768.

It's everything I bought a KVM switch for, But absolutely nothing from what I chose THIS KVM switch for. (Higher Resolution)

Other Thoughts: There's a button. I like this button, this button is my friend I touch to switch between pcs
