No idea. I'm not familiar with the CHIP Pro, just quickly read the datasheet. The SOC contains Mali400 GPU, so in theory it should capable for video output, but I can't find any mentioning whether the video capability is enabled in hardware/software level in CHIP Pro (i.e pins wired & Linux driver). Raspberry Pi has similar problem: although it uses a SOC designed for mobile applications, there are no open source solutions to connect generic smartphone displays to DSI port, and HDMI is very bulky/over-engineered solution for transferring video signal over few centimeters. (Blame Broadcom, not the Foundation.)
