I don't usually write reviews but this might help those who need a change and don't know where to start. I originally bought a non-powered UGREEN KVM switch a few months ago and everything worked fine, but now it's completely useless with the keyboard and mouse shutting down every 3-5 seconds. I tried this switch based on reviews and so far so good! The setup wasn't as crisp as UGREEN's, but after playing around with the setup for two hours, it finally worked. Laptop for work, I have all 3 monitors displayed (32" Dell, 21" Dell and my laptop screen) and when I switch to my NUC only my 32" works for me. This is the setup that I have used with UGREEN before but it was all done over VGA.This setup is nicer as everything works either from DVI to HDMI or directly over HDMI.I'll check back in a few months to make sure everything works and post an update ready.Update - After using this switch for a little over a year, it still works like day one.I'm glad I bought this switch.
