# BPI-R1 HDMI interfact

BPI-R1 has a standard HDMI 1.4 interface. so We can use HDMI-to-HDMI cable to connect BPI-R1 to the display monitor that has HDMI interface.

But If the display monitor doesn't have HDMI interface,only VGA or DVI port. We should use HDMI-to-VGA or HDMI-to-DVI cable to connect the BPI-R1 to the display monitor.
