Summary: My motivation for buying this was needing a DVI KVM but there are some things that people need to be aware of before buying it. 1) You cannot send analog signal though this unit. VGA won't work. It is digital only. A VGA->DVI will not work. Read up on the different types of DVI 2) I have noticed some problems using wireless mice/keyboard. I have to plug a keyboard directly into one of my workstations to change BIOS settings.
Good quality and big upgrade over my old VGA KVM... I can finally see the detail my systems were capable of!

Summary: I finally have DVI outputs on all my computers with the recent purchase of a new game card. I bought this to replace a VGA KVM that has worked reliably for many years. People have reported that the cables are heavy but I found them no worse than the VGA cables I was using, and these new cables carry audio in/out too! The best thing about this new switch is the clarity of image and detail I'm getting with my 23" IPS monitor.
Summary: This is a fantastic product. I initially searched for something cheaper. I only needed 3 ports, not 4, so I thought if I was diligent I could find something to save some money. Finally, I bought this and I'm glad I did. I've had switches similar to this in the past, but the USB switch was the key to my going with the IOGEAR. The interface for the switch is intuitive and well designed. I had three PCs connected in minutes.
Good product plagued by wireless keyboard/mouse issues.

Summary: By it's description it looked ideal for what I needed. Unfortunately, neither my Microsoft nor Logitech wireless mouse/keyboard combos worked at all. I really don't have time to waste and try and troubleshoot this issue - I would have preferred that it worked out of the box like my old StarTech. I setup my old 2-port KVM and boxed the IO-Gear unit to return.
Fantastic DVI KVM for a home office, more feature rich than product description suggests.

Summary: So far I am very satisfied with this product. First, while somewhat expensive, it is a great deal for a 4 port DVI KVM with all 4 KVM cables. I bought this because I run a Windows 7 workstation, Mac OS workstation/home server and have a dock for my work Lenovo T440 laptop. I work from home frequently so I need to be able to rapidly switch between the various environments. I was using a cheapish IOGEAR 2 port VGA KVM.
Great device for managing many computers using one monitor, keyboard and mouse!

Summary: This is my second one after a lightning strike to my house fried the first one. Love this device for my many computers and one monitor. Very easy to flip back and forth between computers, and uses the DVI connection so a very clear image. Well worth the cost for the person with multiple computers. Makes managing them easier! A recommended buy!
Excerpt: Well built and solid. Works ok. With two exceptions: a VGA monitor with a DVI adapter will not work with this switch. The USB connections for wireless Logitech mouse and keyboard would not work. In both instances I had to swap out my equipment.
Summary: I had been using an old ps2/vga KVM switch for years and finally tired of having to use adapters, monitor button pressing and all kinds of things to keep my system running. I finally bit the bullet and purchased the GCS1104 to accommodate my new office. After finally getting my new office setup, I was anxious to get this thing setup. Out of the box, the unit appeared well built, rugged.
