Review on 🔌 High-Performance KVM Switch HDMI 4 Port Box: UHD 4K@30Hz, 3D, 1080P, USB-B & HDMI Cables Included by Pressure Cook

Overall the block is good and it's nice that you don't need a separate power supply. One cable less. I wish the mouse and keyboard ports were on the back because I have a flat desktop. With the KVM switch, that's no problem. I didn't realize this would be an issue until I set it up. I had some initial issues with the mouse not being very responsive and the computer not always recognizing when the cursor was over something to be selected or clicked. I had to move the cursor a millimeter or two to find the sweet spot. I used a cheap wired mouse and replaced it with a Logitech M720 which was idle. The M720 has better tracking and the problem is gone. Another benefit is that the USB dongle eliminates the need for another cable.
