Review on TESmart 2 Port DisplayPort 4K@60Hz Ultra HD 2X1 DP KVM Switcher With 2 Pcs 5Ft KVM Cables And DP Cables Supports USB 2 by Steven Nina

Works well today, worked two days but problems: 1 - It was clearly an OPEN BOX. All plastic envelopes containing the contents were torn open and the contents removed. Although everything including the torn plastic was put back in the box. All protective tape around the edges of the opening has been cut off. I was charged full price as if NEW. This was my last purchase from this supplier. 2 - The two "powered" Displayport cables were BAD (the system reported communication errors with them). Maybe that's why the item was returned. I had to replace at my expense. Using a Corsair K20 gaming keyboard with a Logitech mouse wirelessly connected to the Switch USB port on the back of the Switch. The monitor is an ASUS Predator 32" with G-Sync at 80Hz (the monitor runs at 144Hz). Everything works as it should. There might be problems if I try to update the frequency above 80Hz, we will I have replaced the HDMI TESmart KVM switch with this one to connect all the display ports It has served me well I hope this one does the same and will update this review if anything changes.
