Review on 2 Port Dual Monitor HDMI KVM Switch with 4K@30Hz, 2 USB 2.0 Hub, Wireless Keyboard & Mouse Support, Hotkey Switching, No Power Adapter – Includes 4 HDMI Cables by Charles Purnell

Very happy with this purchase. I have two computers that output to two HP 27" 1920 x 1080 monitors. I have an old computer so I also had to buy a pair of "j5 create" video adapters and a special VGA to HDMI cable so I could convert the computer's USB port outputs to this computer to an HDMI input in the switcher (if you're confused as I think about it, just understand that you need to convert all of your computer's outputs to HDMI to feed the back of it. As a bonus, I was ALSO able to add a wireless keyboard and adapter mouse to the USB 2.0 port on the front of this switch and it works great no matter what computer you use! It's impossible to visually see the colored lights that indicate if the input is coming from "PC1" or "PC2" ", unless the switch is at eye level, or the switch is facing up towards your eyes (which I don't since it's sitting on a table). The little rubber pads came off too, so I just glued their second adhesive. I am back. I would recommend this switch as a really handy solution to quickly switch between two PCs and use two monitors at the same time.
