RK3399: Ubuntu Display Limited to 1024x768 only When connected to 1080P monitor

I have received my RK3399 board yesterday. I connected the HDMI output to a TV. In android system the display looks fine.

However when I switched to Ubuntu OS, I’m only able to select 4 resolution with the highest one is 1024x768. How could I enable the support for 1080P?
