Summary: Don't get me wrong - I like the DVI-I ports, I think the cables should be DVI-D, and those cases you want to do analog pass-through you can use VGA->DVI-I converters. The need for DVI-I cables is the abnormal case, rather than the norm, and really limits the connectivity more than having DVI-D cables with DVI-I ports.
Pros: 4 Client Ports, with push-button selectors. Dual DVI ports able to use high screen resolutions on both monitors. You can separate the selection of KVM from USB hub, as well as KVM from audio.
Cons: Using devices on the USB hub is tough. Every time you plug a device into the hub you lose Mouse control until you re-plug in the Mouse. When you unplug the USB device you again lose the Mouse control until you re-connect it.
Summary: The highest priced junk i have had the misfortune to need. Do yourself a favor and keep looking.
Pros: Considering it broke within 5 weeks, any pros that may have been listed have become moot - It was nice to have dual DVI monitors on a KVM for this many machines, however in just about five weeks I have lost output to one of the monitors... not much i can do with it now but keep paper from moving around - Great, just what I wanted to spend my hard earned $$ on.
Cons: Going out on a limb here, but poorly build...
Summary: Too much money for vastly too little product. Learn from my experience and buy another vendor's KVM switch.
Pros: Dual DVI with individual switches (as opposed to an earlier Linkskey dual DVI with one progressive switch) and USB.
Cons: Slow switching speed between computers. Cannot keep up with 1920x1080 graphics resolution - a secondary window with a different resolution appears. First power outage and the thing died. Power supply still put out 9V. Junk!
Summary: I would have gone with two cheap KVMs if I knew it $600 would only get me 2 years of operation. I would buy this again if it had 3 year warranty, it is probably still the best option for 1 KVM with dual DVI monitors.
Pros: Works very well while it lasts
Cons: Keyboard and mouse USB ports died after 1 year. KVM began making very loud high pitch noise while the power cable was plugged into it so I disconnected the power and it worked on USB power for about 1 month and then completely died. Unfortunately the warranty is only one year.
Summary: If the 7.1 connections on your system are not fully occupied (2.1, 4.1, etc.) you will pick up hum as the connections on the KVM are not terminated. Be nice if they supplied termination plugs for the unused jacks.
Pros: Does what it says. Did not need to load software. Worked anyway.The software is for controlling individual items and keyboard switching which I don't use. Provides all the cables except could use more for the 7.1 stuff.One computer has DVI/Analog conversions and works just fine. The other is DVI/DVI and it works fine. The unit will only pass resolutions that your monitor can handle. The factory said that this unit will pass 1920 x 1080P. Strong metal case.I used it to...
Cons: Instructions say to hook up DVI connectors while the unit is "hot". I did not do this. (scared)
