Review on 🔁 CKLau 4Kx2K@60Hz 4:4:4 DP Displayport KVM Switch 4 Port - Includes Cables, Audio, and Microphone by Ronnie Staver

Unfortunately my block doesn't work. I installed it between the GTX 1080's DP out port and the port 1 output on the DP in port of a Dell U3415W monitor (at 3440x1440/60Hz). When the light came on, I was able to switch inputs, but the display received no signal and stayed in sleep mode. I also tried the motherboard's DP output (IGP output enabled) with the same result. It's a shame, features + quality hardware at this price point, if it worked it would be a great deal. Three of the four included DP cables appear to have been repaired (black tape? Really?) so they may be defective cables, but after hours under my desk, changing cables, etc. it looks like I'll have to return it. If the seller wants to contact me, I would rather solve the problem than return the product.
