Review on VisionTek VT4000 Dual 4K Laptop Monitor Docking Station, Dual UHD Video, HDMI, DisplayPort, USB 3.0, USB-C, RJ45 Ports, Mac & Windows Compatible (901005), Black by Antonio Curry

I can only use external monitors and speakers. That's all. Nothing else works for it. The Ethernet port, while technically fine, stops working for about a minute every few seconds. Are you trying to stream music or videos? No, it stops every 30 seconds. And it's the same ethernet cable and router that I used with my old tower with no problems. I had to completely disable the dock's ethernet port and only use the laptop's WiFi. USB 3.0 ports only work with a mouse and keyboard. Plug in the USB flash drive, it connects and opens the folder. But try to transfer a file and you hear the sound of Windows shutting down and bombarding while you transfer files. If I connect the USB stick directly to my laptop, I have no problems. One more thing, my laptop won't boot when the dock is connected. If I need to reboot, I need to disconnect the dock first. This is classic "bad peripherals" behavior. I've already checked the website for a firmware/driver update and it says I'm using the latest version. It just doesn't work.
