We use i.mx6 SABRE Board(BSP android_jb4.3_1.1.0- ga_source.tar.gz). We need use Dual Displays(LVDS and HDMI Displays). But HDMI don't full screen.

LVDS and HDMI dual displays bootargs is:

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,bpp=32 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb2:off fbmem=28M fb0base=0x27b00000 vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale


I found the HDMI output resolution is affected by an LVDS resolution. If I set LVDS resolution to 1920x1080,HDMI display can full screen. But Our LVDS resolution is 1280x800.

How can i do?
