Review on 🖥️ StarTech.com Dual Monitor DVI KVM Switch - Dual Screen Display USB KVM Switch with USB 3.0 Hub & Audio - Dual View KVM - Compatible with Dell, HP, Apple, Lenovo - TAA Compliant (SV431DD2DU3A) by Sean Davis

Pros: Pretty quick switching between 4 dual monitor configurations. I don't want to be picky, but with a product like this, you either do it right or you don't do it at all. Initially, the switch seemed to work well enough, and it's a real pleasure to toggle between the four dual-monitor settings. However, over time I noticed that my illuminated keyboard flickered at times. Then I noticed the same thing with my mouse. During such events, the mouse/keyboard became unresponsive and skipped clicks and key presses. This happens several times an hour (6-7 or so). The reason this issue is considered severe enough to warrant such a low score is that during such flickering events, a key press can cause the mouse or keyboard to malfunction. The worst example I have is when I was typing during one of those flickers and after that my 'v' key became unresponsive. It's not bad for a workstation, but if I were still an active gamer it would be a huge hurdle. This issue may be more keyboard related and is only made worse by KVM. I will try to solve this problem by using an externally powered USB hub to interact with KVM and possibly another keyboard.
