Things like USB ports that can be used across devices and hotkey options that make switching between computers quick and easy.One thing that I do want to mention though is that you WILL want to read the manual to take advantage of all this has to offer.
Obviously if you need this more than 5 foot or so in distance I would definitely get an extension cable.If you have a wireless keyboard mouse, you only need one set of the receiver or physical connection to the back of the KVM switch.
I've tried with Biostar TB250-BTC & BTC+ motherboards as well as ASUS B250 mining board and all have been working great.Aside from that, the price could be a hair lower at $129 or so and if they can sell the 8-port for $239 or so it would be so worth it.
I have owned this switch for over 8 years now and use it everyday for at least 10 hours a day.Recently I upgraded my Keyboard to a Logitech wave wireless keyboard and mouse.
I am pleased to report that my old KVM is now working with my new Logitech Wireless Keyboard and Mouse through the KVM Keyboard USB Port.Should note that the extra buttons don't all work but I don't really care about them.
I connected the cables to the master ports on the KVM switch and tried using port one to the computer.
Still, no response, so I choose port 3 on the KVM switch, the mouse movement was sporadic across on the screen making it difficult to use, and the keyboard was not responsive.
I tried using the KVM switch on a different computer Windows 7 with a different add-in card I got the same result (port 1 -no video, keyboard, or mouse ports 2-4 video mouse movement sporadic, and no keyboard)so at this point in think, I just received a faulty unit.I request a replacement unit.
Plugged everything in the respective port and still no picture and the mouse moment was sporadic.I bought one of the older KVM switches that I purchased a few years ago, and everything seems to work okay.
I got this to replace my old IOGEAR 4-port DVI KVM.
