    Works only at a very basic level, has MAJOR flaws
  

*by E***I on Reviewed in the United States on March 3, 2019*

So, yes I can hook up 4 devices to this KVM and use my 4K monitor over DP. However I hit the following issues, which to me renders the KVM pretty much useless:- Display emulation isn't available, which means the monitor will be redetected AFTER EVERY SWITCH, taking about 10 seconds each round. This also leads to losing the screen layout on computers which use the KVM monitor as a second display (say Windows' "Extend to Desktop" mode).- The max supported 4K resolution isn't stable using the supplied cables, or higher quality ones I tried. Screen flickers once in a while (esp after complex scenes), and display goes dark for 5-10 seconds. This doesn't happen when I connect the source machine directly to the monitor using the same cables, which means it's not a problem caused by the cables, the computer or the monitor. THis proves the KVM has signal quality issues. Bottom line is I'm forced to downgrade to 2560x1440 resolution. Unacceptable after having paid $270 while product specs clearly boast this feature.- The KVM wasn't able to detect my Microsoft Wireless Ergo Keyboard when connected to the KB port at the back. I had to connect the receiver to the front port, which in turn means the keyboard is also redetected (beep-boop!) every time I switch to a different computer. Super annoying after I paid $270, this is a very common KB and it's supposed to work per product specs.Bottomline is this KVM isn't good for switching back and forth. It's only usable if your workflow involves having a single active computer hours on end, and not need to switch every 15-20 minutes like I need to.

    Ignore the reviews - multiple products are under the same listing!
  

*by J***N on Reviewed in the United States on October 26, 2018*

IOGEAR GCS1904 4-Port 4K UHD DisplayPort KVMP Switch with USB 3.0 Hub (TAA Compliant)I agonized over the decision of which KVM to buy... so many choices, but most were very poorly reviewed.  Everybody complaining about losing handshakes (HDCP is defective by design) and nothing working right.  I have an eGPU serving as a TB3 docking station for my Thinkpad, and a standard Dell docking station for my Dell... I regularly have occasion to work on other PC's and even a docking station for my Samsung cell phone (it was free).  I *HATE* plugging and unplugging cables and wish everything had its place and was in said place...I've had *ZERO* trouble with this station - even with the complex eGPU setup.

    No Video Output
  

*by D***H on Reviewed in the United States on April 25, 2020*

I should have paid attention to "no video after replacement."  I, too, have liked IOGear for quite some time, but when I tried to get this item to work, it would not provide any video output.  I checked all cables and inputs.  The cables all worked flawlessly when connected directly to the computer and monitor, but no video output from the KVM.  It also did not like running both my Razer Naga mouse and my RealForce RGB keyboard plugged into the "appropriate" ports on the back, but I'm not surprised; I have yet to find a KVM that will support these natively.  All I can say is, I'm not even bothering trying to go through customer support on this, I am so thoroughly disappointed.  Chalking it up to a lesson learned, and looking for something else.  "Buyer beware" has never been so acutely felt as this.
