# BPI-R2 HDMI interface

BPI-R2 has a standard HDMI 1.4 interface. so We can use HDMI-to-HDMI cable to connect BPI-R2 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-M2 Ultra to the display monitor.

Note: if the HDMI-to-VGA/DVI cable is a bad quality cable,it will go wrong on the monitor display. please choose a good quality cable for BPI-R2
