Review on 🔌 AV Access HDMI USB Extender(HDBaseT) KVM: Long-Range 4K 60Hz 1080p 120Hz Over Cat5e/6a, USB2.0 Ports, No Signal Loss, Low Latency by Paul Haswood

I have a gaming PC in my office on the second floor and a home theater in the basement. Wanting to play games on a home theater meant I had to make sure the signal and controls worked reliably two floors away. The 4k HDMI extender allowed me to do this without too much trouble. Here are some things you should know: 1) USB ports have a current limit of 0.5 amps, which means that no device connected to it can draw more. If you exceed this amount, the device will restart and you will often love the video signal. Fortunately, there is a workaround. * Workaround * Connect a powered USB hub to the expander port and devices connected to the hub will not overload the expander. 2) I've only used this in a 1080p configuration, so I can't comment on how well it performs in 4k. However, providing a great gaming experience over two floors was not a problem. No lag between controllers, mouse, keyboard, video and audio. It just works. I would recommend this product.
