Title: No 4K
I just got my RK3399 board.

I can successfully flash both the non-beta and beta Ubuntu 16.04 images and boot. When using the non-beta image with a 4K monitor I get a band of static on the right side of the screen (see attached image).

When using the beta image, 4K resolution is not available and it looks like the driver is not loading (checking with `glxinfo` - rockchip_dri.so is not found).

What am I doing wrong?

Microsoft的SC-900考試認證是屬於那些熱門的IT認證，也是雄心勃勃的IT專業人士的夢想，這部分考生需要做好充分的準備，讓他們在SC-900考試中獲得最高分，使自己的配置檔相容市場需求。
