Review on 🖥️ 4K 60Hz Dual Monitor KVM Switch HDMI + DisplayPort - 2 Port with Audio, USB 2.0 HUB - CKL-622DH by Mondreka Rosenhoover

TLDR - The product has many flaws. No support. Buy something else. I bought it to connect my work and home computer. The instructions say 144hz is not supported so I tested 1440p 60hz and 1080p 60hz and both monitors flickered intermittently. It says don't connect a gaming mouse and keyboard to the mouse and keyboard ports, guess what? That does not work. After all, I was hoping that my graphics tablet might work somewhere. general. no HDMI went fine but I couldn't get the pen to work. All USB ports were not working upon arrival, Displayport was not working and sometimes even the HDMI port was faulty. $189 I was hoping this came with support and the instructions said to contact our customer service. but no phone number or email address given. I contacted Revain and the guy said we should try to fix the error and he put me on hold. and after a few minutes they hung up. The item came right in the shipping box so there was no visible support to contact, but it was pretty clear there was nothing tech support could do. The device was defective, I am sending it back for a refund. For $189 I can buy a couple of separate switches to do what this thing does and if it doesn't work, there's a lot less risk. But based on my experience I can't recommend it to anyone. There's no camera, no tech support, and even the instructions made it very clear that it wasn't designed for gaming, and that's when it works, which it doesn't. It's weird giving stars for 0 results on the best days. and my day went smoothly.
