I tried this bootargs of dual display-

setenv bootargs console=ttymxc0 init=/init androidboot.console=ttymxc0 video=mxcdi0fb:RGB24,1280x720M@60 hdmi video=mxcdi1fb:GBR24,VGA-SVGA di1_primary vga ip=none pmem=128M,64M fbmem=28M gpu_memory=128M vmalloc=576M

 

I got both VGA and HDMI displays but HDMI screen area is scaled down.

 

Now I turned off VGA and HDMI. Then configured new resolution for HDMI and turned it ON.

 

echo 1 >/sys/class/graphics/fb0/blank     #vga off

echo 1 >/sys/class/graphics/fb1/blank     #hdmi off

 

 

# cat /sys/class/graphics/fb1/modes

S:1280x720p-50

S:720x576p-50

S:1920x1080p-50

S:640x480p-60

S:720x480p-60

S:1280x720p-60

S:1920x1080p-60

 

# echo S:1280x720p-60 >/sys/class/graphics/fb1/mode


# cat /sys/class/graphics/fb1/mode

S:1280x720p-60

 

# echo 0 >/sys/class/graphics/fb1/blank     #hdmi on


Still the hdmi is not using the entire display area. Both ends are left blank.

 

 

.How can I make my HDMI display "FULLSCREEN"?
