+* If you want to capture VGA from your server instead of HDMI, buy the [VGA-to-HDMI converter](https://aliexpress.com/item/4000553298530.html). Some VGA HDMI adapters have issues with not supporting all resolutions and refresh rates.
 * PiKVM can be powered using PoE, but it is not recommend to use the official PoE HAT: it is unreliable and [not compatible with the HDMI bridge](https://github.com/pikvm/pikvm/issues/6). Use any other PoE hat without an I2C fan controller.
 * **Don't use random relay modules or random optocouplers!** Some relays or optocouplers may not be sensitive enough for the Raspberry Pi, some others may be low-level controlled. 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).

Devices are connected via PS/2 so USB media support does not work. The setup relies on a VGA-> HDMI adapter to make the video signal work and there can be issues with unsupported VGA resolutions with some adapters. KVM hotkeys and switching all work and so does mouse and keyboard. |
