Questions about imx6 triple display.

[simmisxu]

Hi All,

    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?

Thanks.

Simmis.

could you give me more detailed information, what uboot command do you use?

you just want to play video on the second lvds, but you find the video on the hdmi too, right?  could you tell me the steps you test and what demand you need?

Hi,

can you guys give me some pointers on how I could have a triple display scenario (lvds + hdmi + cvbs from an adv7391) working? At the moment I can only have lvds + hdmi or lvds + cvbs but not all of them at the same time.

Thank you.
