But it has some disadvantages compared with recommended [HDMI-CSI bridge](https://aliexpress.ru/item/4000102166176.html): USB gives a lot of latency (200ms vs 100ms) and it doesn't support stream compression control (you won't be able to use Pi-KVM in a place with a poor internet connection). It also cannot automatically detect screen resolution. All this is caused by the hardware limitations of the dongle itself. In addition, some users report hardware problems: the dongle may not work in the BIOS or simply stop working after a while. It's a black box, and no one knows what's inside it. If you have problems with it, it will not be possible to fix them. +It's completely supported and Pi-KVM works great with it.

Either use relays that are activated by a high logic level, or follow the design provided and buy an OMRON. See details [here](https://github.com/pikvm/pikvm/issues/13). drawing
