My HDMI display has 1080x1920@30Hz. I want Hikey 960 to work with it and look like a smartphone.
I tried adding kernel boot parameter “video=1080x1920@30”. It probably rotated because a regular monitor didn’t work when connected to the board and the display did show something.
I guessed it was timing problem and add display-timing node to the device tree (under adv7533). But it looked like the driver didn’t read the dt.
Any idea about this problem?
Btw, the display works well on windows.
