Hi Community,

 

I'm working on i.MX6 Quad sabre-SD platform and build Android 6.0 for my OS system.

Now I'm working on HDMI and LVDS show different resolution at the same time.

Here is my u-boot command line settings.

bootargs=console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,bpp=32 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb2:off video=mxcfb3:off vmalloc=256M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=FX100 cma=384M androidboot.selinux=disabled androidboot.dm_verity=disabled no_console_suspend=1 enable_wait_mode=off

 

ldb is on mxcfb0 and HDMI is on mxcfb1.

Here is the situation.

My LVDS panel resolution is 1024*768 and my HDMI resolution is expected to FULL HD.

But when they showed up, HDMI showed 1024*768 resolution instead of FULL HD.

 

Question:

  1. Is that possible HDMI and LVDS panel showed in different resolution?
  2. If can how can I complete it? Do I need to modify kernel driver?

 

Thanks in Advanced!
