Review on 💻 CKL Triple Monitor HDMI KVM Switch 2 Port: Audio, USB 2.0 HUB, 4K@30Hz - Mirrored/Extended Display for PCs & Laptops (CKL-923HUA) by Johnny Nguyen

- The HDMI and DVI ports on my PC are normally capable of outputting 4K 3840 x 2160 at 60Hz when connected directly, but neither resolution works even when I have them on 30 Hz sink. In both cases I can see the image, but it is badly distorted and unusable. The display port output works with an HDMI adapter, but only at 30Hz. Keyboard connector on KVM not working. When I connect a keyboard to this port, the keyboard doesn't work at all. On the other hand, if I connect to a USB 2.0 port, it works. Mouse port on KVM is not working properly. It works fine with my PC, but when I switch to my Mac, the mouse moves but I can't click. It doesn't make any sense to me, but that's what happens. On the other hand, if I connect to a USB 2.0 port, everything works. - Sound NOISY.tldr; If you wrestle with the video outs long enough and use a USB hub for the keyboard and mouse, most of the time it works.
