    hdim + lvds is possible. 2x lvds isn't (because the 2nd lvds pins aren't exposed).

    @jas-mx @NickoR
    I think that UDOO Quad isn't able to display 2 different screens (HDMI and LVDS) out-of-the-box, without changing/adding any line of code.
    This forum is not a Google bot. The LVDS screens for UDOO are the ones contained in the shop: shop.udoo.org

    Yes your right, it would require some simple changes to dts files to enable both.

    Hello ! thank you!
    If this is just a code change, this is perfect !!! :D

    I was just afraid that this is only the mirroring!

    @NickoR
    Yes, it's just a code change.
    If and when you will write such a code change please inform the community and we will update the website.

    I hope @NickoR will be able to do this "simple" code changes to dts (device tree files). To do the changes is simple, just edit a file. To figure out what has to be changed, what dependencies has to be taken into account is something else.
    Then does this change also apply to Android because that is what the TS is heading to.

    Android's display interface doesn't work the same way as linux fb, so this change isn't applicable to Android. In fact having 2 display is only useful if you can point different applications at the separate frame buffers under linux.

    oh okey. thank!

    I was just thinking that the change valid under linux was on android.
    thank you very much
    In any case, I do not advance. no information on the possibility of dual independant display on android..
