    I have a lattepanda alpha and i have both the 7in and 10.1in. When I plug in the LP with either the 7 or 10.1in nothing comes up red light flickers fast then goes normal, then it stays solid like normal boot then i press the power, the blue light just flickers. But when I connect to hdmi it works.

    If i could get some help o greatly appreciate it.
    Thank you.

    Try regular HDMI monitor first.
    LattePanda Alpha needs eDP monitor with proper spec., wiring, powering, etc. to work. Not anything you throw at it.

    Regular monitor work through hdmi. The 10.1 and 7in ips display that connects to the alpha with the ribbon strips isn't work. Monitors and tv works just fine.

    Please provide links on your 7" and 10.1" ips LCD screen. What are you referring to?
    If you are talking about the classic LattePanda (i.e., not Alpha) 40-pin LVDS based LCD panel,
    then obviously there is a mismatch.

    LattePanda Alpha's 30-pin LCD connector is for 30-pin eDP display, not the 40-pin LVDS type.

    Both links are for the original LattePanda, not LP Alpha.
    LP classic uses 40-pin LVDS, while LP Alpha uses 30-pin eDP interface method.
    They are incompatible with each other.

    Now that LP Alpha is out...

    The ips LCD panel seller should update the listing to state that
    - it's for LP classic
    - not compatible with LP Alpha

    This has been the second thread I've seen people encountering the same issue.
    The seller should make it absolutely cleat to avoid disappointment.
