Details
When using a switching device with a computer, the switch must switch
both video and USB to enable both video and touch (USB) on the
SMART product.
Make sure any devices connected in line with a SMART product pass
the video handshake signals, such as Extended Display Identification
Data (EDID) and HDCP. The use of products that do not pass those
signals can result in unwanted behavior or no output.
