Problems with HDMI in Android

[korovinu]

Hi,

I need HDMI support only in an Android image. I have a few problems:
1. I didn't managed to switch off LCD screen. When I set screen0_output_type = 3 in a20-olinuxino_micro.fex file, I have pink screen on HDMI output
2. If I use LCD+HDMI, HDMI output works but a picture has black margins. I use a PC monitor without overscan settings
3. HDMI resolution is always 1080p. I didn't managed to change it to 720p as I need.

Can anyone help with these problems?

Your configuration of .fex file is wrong. Read http://linux-sunxi.org/Fex_Guide for success config.

I have tried different configurations based on http://linux-sunxi.org/Fex_Guide
According to http://linux-sunxi.org/Fex_Guide screen0_output_type: Output type for screen0: 3 - HDMI
What is wrong?
