Review on 🔀 2-Port USB VGA KVM Switch with Cables for PC Sharing, Supporting Video Monitor and 3 USB Devices - Keyboard, Mouse, Scanner, Printer by Firman Harrington

Good price and delivery on time. Your ONE VGA monitor/display cable connects to this KVM switch. . (It has 3 USB inputs) Two cables are included. Two cables are also connected to the KVM switch. The other end of each cable is a standard VGA/USB connector. Connect the VGA and USB connectors of the first cable to Computer A. Do the same for computer B with the second cable. Turn on both computers. The KVM switch has an A/B button. Clicking it will switch between the two computers. But you only use one monitor. Whichever computer you choose, it will appear on the screen. And the same single mouse and keyboard will work no matter which computer you choose. CONS: There was a noticeable loss in video quality for me. Every computer screen looks blurry/blurry. When I do NOT use a KVM switch and connect the monitor to one computer at a time, the video image looks fine. Filtered by KVM quality is lost. Essentially, the KVM switch causes two connected computers to lose video quality when connecting to a monitor. Not bad, but definitely noticeable. The mouse and keyboard work well whichever computer is selected, no complaints about the USB functionality. FOR ME: My monitor actually has two inputs, so I took two separate VGA cables and ran each one from ONE monitor to two computers. I still use a KVM switch for its USB switching. ONE mouse and ONE keyboard are used for both computers, I press the A/B button on the KVM switch to switch computers, but I don't use the VGA connections from the KVM due to video quality loss.
