A great product

  • Excerpt: I work with two Kubuntu 12.04 Linux workstations continuously connected, and a Windows 7 employer's Lenovo 530 laptop that I connect every evening on returning home and disconnect every morning when heading to work (via a Lenovo docking station continuously connected). My monitors are dual Dell 3007 2560x1600 dual-link DVI, keyboard Avant Stellar (PCI connector via USB adapter), with a Microsoft wireless mouse.
  • Pros: Easy To Set Up

I Agree with other Reviewers

  • Excerpt: This is the best KVM that I have ever owned. It works very well for two monitors. I game with it and I do not notice any video or audio degradation. Computers boot better on this kvm than any other kvm that I have owned in the past. Hotkey switching has worked perfectly after getting a wired keyboard; wireless keyboards are not supported. It is a large unit and it is under my computer table. I have never had to reach under the table to correct this kvm.
  • Pros: Easy To Set Up, Reliable connection, Smart Features

doesn't work with all devices

Eric A., Newegg
12 January 2014
  • Summary: i would rather see iogear make a wireless remote for switch computers and get full keyboard and mouse support.
  • Pros: I bought two of these. it works just OK, it is nice to not having to boot each computer individually now.
  • Cons: only works with the basic keyboard and mouse devices, huge con. will not work with a Logitech mini unified receiver plugged into the mouse port on the back, my older gcs1764 did work with this mouse. I get 'device driver software was not successfully installed" with this KVM. I don't understand why it would be particular with mice as there is no mouse functionality to the switch, but the mouse works in the front port.

audio quality diminished

Dennis F., Newegg
13 September 2013
  • Summary: I'm attempting to make this KVM work by boosting the audio signal
  • Pros: this KVM works as described and is reliable. I've had problems with other KVM's losing the mouse and having to disconnect and reconnect in order to get the mouse to work sometimes after switching. That issue does not occur with his KVM.
  • Cons: the audio signal gets diminished going through this KVM. I thought it primarily poor that feature as most KVM's tender work.

Best Dual Monitor KVMP from Best Seller

19 March 2013
  • Excerpt: I purchased this device after a lot of research, because I wanted a good KVMP that I could use to swap between 4 computers, some of which support Dual Monitors. The device is top notch, included a full set DVI/Audio/USB connections to/from the computers. I highly recommend B&H as the source, which was the cheapest when I bought - they delivered ahead of schedule and communicated well throughout the transaction. I will buy again from B&H.
  • Pros: Able To Eliminate Beep, Cross Platform Support, Easy To Set Up, Fast Switching, Mousekeyboard Emulation, Smart Features

Good job IOGEAR

  • Pros: TL;DR: Best thing since sliced bread.
  • Cons: Audio is consumer grade, but still usable for day-to-day: slight whirring sound in the MIC input and some cross-channel bleed between MIC and OUT.

Great KVM - wish functionality was a bit different

James M., Newegg
29 January 2013
  • Summary: This is my second iogear KVM and this one is a vast improvement on the one I had before, technically. I really like both, but my G500 mouse and Corsair K60 keyboard do not work AT ALL via the GCS1644's keyboard and mouse ports.
  • Pros: Dual DVI monitors, audio (if you need that), USB 2.0
  • Cons: My keyboard and mouse did not work in any capacity when connected via the "standard" keyboard and mouse ports.

A Typically Excellent IOGear Product

TXTad, B&H Photo
6 September 2012
  • Excerpt: With two 24" 1920x1200 monitors, I use this to switch between a Linux computer and a Mac Mini, both of which run dual displays, and a Dell Windows 7 laptop using just one display. One thing that I didn't realize it could do when I ordered it, but has proven to be very handy, is the ability to switch the audio, USB and KVM functions separately as well as together.
  • Pros: Easy To Set Up, Fast Connection Speed, Separate Function Switch, Switch To Specific Comp
  • Cons: Expensive, Large, No Brackets

Compared to LDV-DM04ESK

Curt C., Newegg
24 June 2012
  • Summary: My Pros and Cons are specifically related to the comparison with the Linkskey LDV-DM04ESK. I have 3 computers and the Linkskey always had trouble with two out of three of them. The GCS1644 has no problems with any of them. Each computer has the same video card (PNY NVIDIA Quadro NVS 295) but a different ASUS motherboard.
  • Pros: 1) Don't need to have the PC selected when Powering up.
  • Cons: 1) When switching to next PC, it doesn't skip unconnected ports.
