Review on 🔌 Wireless Keyboard Mouse Supported 4 Port VGA KVM Switch with USB Hub, Audio, and Push Button Switching by Ronald Bleimeyer

April 2020 --- Just installed for 3 desktops: win10pro, win7pro, XP. All three work perfectly, shift perfectly. Instructions for use, so I downgraded to 4 stars. It's a tiny bit smaller than the proverbial writing on the back of an aspirin bottle, which is a real annoyance and I really needed a magnifying glass to read it. It would make much more sense, at a unit price of approx. 50 cents, to make this instruction folder twice as large and to make the font twice as large in all sizes. The doc folder doesn't explain how to connect cables or how they work. I will do here. The video/audio cables only have a VGA connector on one end for connection to a KVM hub, while the other end has a VGA connector, keyboard connector, mouse connector and USB connector for desktop connection. What isn't explained is that only the USB and VGA connectors need to be connected - apparently - and this isn't explained in incredibly small print anywhere in the documentation --- the VGA connector captures video from the PC, while USB signals for captures the mouse, audio and keyboard hits. What is confusing is that they are all combined at the PC end of the cable and at the other end of the cable - which only has a VGA connector - carries all these signals - mouse, KB, sound and video. Once I figured that out, everything worked. When connected to a hub, you can plug in or unplug the USB headphone jack and plug the headphones back into just one of the desktops and audio will only stream through the headphones regardless of where they're plugged in for that selected desktop. The hub has very small markings for VGA input cables as 1,2,3,4. Also, the document does not clearly explain the 3 OUT connectors on the video output side of the KVM hub.
