I am trying to do a triple display demo based on imx6 SDP. The 3 channel are 2 lvds & 1
hdmi and the OS is Android JB.
I have succeeded in dual display, 2 lvds or 1 hdmi + 1lvds previously. And now 3 screens
can all display the Android Main UI.
The problem is that when I use HdmiShow to play video in 2nd screen, the 3rd also display
the video. And then I use command mxc-vpu-test -D "-i *** -x 19" to play video in 3rd screen,
the new video is overlapped on the previous Hdmi video. I can see the overlapped video in both
2nd & 3rd screen.
Does any one have any idea about this?
