    I'm hoping someone can help me find an affordable way to connect Pixel Qi 7" displays to UDOO. I've seen from earlier postings that the 1024x600 resolution is not supported with the onboard LVDS controller, but please let me know if that is not true. It would be nice if we could just make a custom cable.

    Here is the datasheet for the Pixel Qi 7" display (pinouts on page 12): http://www.pixelqi.com/yahoo_site_admin ... 201831.pdf

    Here is a LVDS board that drives the Pixel Qi 7" display and outputs DVI, but it is $395. I would like to find something cheaper:

    Thanks so much!

    Kind Regards,
    - Clint

    UDOO housing/enclosure with 7" screen

    I was looking to see if anyone has either a housing enclosure for the UDOO board with the 7 inch screen or, if not the enclosure, perhaps a CAD drawing? I would love to have something I can take with me that is all-in-one when I am testing between work and home. Can't go wrong with anything you got :D

    Does anybody know, is it standart LVDS connector or special for UDOO?

    I want to use another display, but the question is do I need to solder the wiring.

    It's special for UDOO.
    Regarding other displays I'd like to warn you, you'd have to recompile the driver or create a new one, which is not a trivial task.

    Okay so my kyocera screen works good now ! :D But i can't adjust brightness on android (with the slider in setup), i can only adjust him with resistor to adjust voltage on the touchscreen. Is there a pin on udoo to control brightness with android ?

    Dear Jan,
    the only problem is the connector. Neo needs a different cable from Dual or Quad. By reading that text you linked us anyway it's clear that they aren't the same kit you already find in the shop, isn't it? Otherwise I'll make it clearer. Finally, just to make you relaxed, there will the option to buy just the cable, not another screen.

    Well, the sentence "Two LVDS panels are provided and officially supported by the UDOO Team:" in the Neo docs seems to me that the kits are compatible (or rather the displays, not speaking about the kits at all and how is one supposed to know about the kits in that case?). However, the cable thing is a good news. Thanks!

    I have also tried to go through the display datasheet and Neo schematics hoping that I will be able to find out the differences to make an adapter but so far I was unsuccessful. The display datasheet does not describe the connector pins (or maybe I'm just not smart enough :)). But I'll try to find it out from the Dual/Quad schematics which I suppose has the same connector.

    No, the point is that the connector is different. Let me recheck the schematics

    I meant that Dual/Quad has the same connector as is on the LCD panel, not on Neo. Of course Neo's connector is different, I understood that very well now :).

    @Andrea Rovai when will be the lvds cable available? The full 7-inch kit is available(display + cable), but the cable only is still not available.
