IOGEAR DCS1644 Dual Screen DVI KVM

For those of you who have more PCs then screens a KVM is always the best option. A few years ago their weren’t too many options, especially if you are looking for multiple screens and multiple machines. If you want a three screen setup on one machine your best bet is to stick to one machine and not use a kvm but if you have multiple machines then this is the way to go.


  • Easily handles dual screen mode on 2560+ resolution with movies and games without an issue
  • Very clean and sleek design
  • Came with all the cables to connect 4 machines with dual screens
  • Keeps the resolution of the PC even when it restarts and it isn’t the machine actively on the screen


  • Doesn’t work with the latest wireless mice
  • A bit expensive but most Dual DVI KVMs are around that price if not more

Overall: Love the KVM and it works with any operating system, but I can’t believe it doesn’t recognize my wireless mouse, for something that expensive you would think they could have taken care of something such as this especially since its been around for a while.

Review: Linkskey Dual DVI KVM Switch

Looking for a high resolution dual output DVI KVM has been a very long process. I have at least found one with Linkskeys’ KVM and I waited a little while for the price to drop too. The best part is that the KVM comes with all the connections for all the computers with Dual Display, so you don’t need to purchase any other wires. I have had this unit for about 10 months now and putting it through its paces, I haven’t done a firmware upgrade to it but I don’t really see the point since its working as need with a few kinks. This is a very heavy duty unit which can take whatever you throw it, 1080p movies, high paced games, and complete multi-tasking on multiple screens across multiple computers, the only problem I really see with it is the price thats the major reason why I only gave it four out of five, but over all its an excellent product.


  • Can Handle 4 Dual Screen Computers at very high resolutions
  • Simple setup
  • Boots Mouse and Keyboard in computer so it always detected even if they are connected
  • USB Connection for Mouse and Keyboard to Computer and KVM Switch
  • All keyboard and mouse features work with Vista which didn’t work with the previous KVM, such as touch pad and volume
  • The standard resolution remains at your setting when rebooting and not choosing the specific computer, on my previous KVM it resets to the lowest resolution because you didn’t select it when it was restarting


  • One Special USB for wireless items
  • Hot Key Switching isn’t working with Windows XP (With or WithOut the Software)
  • Hot Key Switching only works with software for Windows Vista
  • A bit pricey
