'''Q: Why PiKVM-A3/A4 does not show the video?'''
A:
* Double-check that the video capture device is connected correctly and tightly. For the CSI bridge, this should be exactly the camera port;
* Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
* Your computer may have turned on sleep mode for the monitor. Move the mouse to turn it off.
