    It looks like the picture is fine, but it just lists the wrong res. It kinda bugs me. I wonder if we could get Lilliput to say anything about this?

    If you have a slightly different version of display than we do, try hooking it up to a Windows PC first. I believe both nVidia and ATI have options for auto-detecting the optimum resolution & timing.

    Copy down the information provided by the ATI or nVidia video control panel in Windows, then fill that information into DisplayConfigX.

    I thought this would be of some interest to you guys:

    http://www.mimomonitors.com/products/mimo-740

    Not only is it cheap, but it all runs off a single USB port.

    I haven't had any experience with one, but it's pretty tempting.

    These are the settings I'm using for my Lilliput 629GL-70NP 2008.

    Horizontal:
    Active: 800
    Front Porch: 24
    Sync: 80
    Back Porch: 88

    Vertical:
    Active: 480
    Front Porch: 50
    Sync: 15
    Back Porch: 20

    Pixel Frequency: 33.630mhz
    Horizontal: 33.901
    Refresh Rate: 60.002

    I used the settings from the first post and just changed numbers until it looked good on the screen.

    This is how I got it to work for me...

    I'm pretty sure I tried almost everything in the thread before I figured out how to get this working!!!!

    And it's a SIMPLE fix at that!

    SO...

    Use one of the aforementioned settings to get your display in 800x480. For example, I used this post:

    Horizontal:
    - Active: 800
    - Front porch: 32
    - Sync: 56
    - Back porch: 136

    Vertical:
    - Active: 480
    - Front porch: 2
    - Sync: 3
    - Back porch: 92

    Refresh rate: 60.015 Hz

    If this does not work for you, just go to the DisplayConfigX page, read the basics of how it works and experiment. And you may need to adjust the image position using the display's on-screen menu. In case you have two Macs, enable the ssh login on the one te screen is connected to - in case of problems, you can go in using ssh and delete the files generated by DisplayConfigX - much easier than having to go to single user mode etc.
    Press <Menu> <up> <up> <left> <down> <down> <down> <down> <left>
    That will get you to:
    OSD ---> Miscellaneous ---> Auto Color ---> Yes


    Then the display will cycle through some automatic adjustments and BAM! DONE!


    EDIT: BTW, this was done on an Lilliput EBY-701

    Awesome! I really never saw the immediate need to get the resolution like that, but now that you verified it, I will try it...

    Just ran my screen blank! Now it's saying not support! Aye-ya!

    DARN! Sorry! I'm not sure what to tell you unfortunately. Since I don't have my Mac Mini yet, I tried this on my MacBook Pro.... I wouldn't think that would matter though.

    Success!!
    Much thanks to Brownaa82 and the prior posts for their input. These settings worked for my lilliput eby701:

    Horizontal pixels:
    Active - 800
    Front Porch - 32
    Sync - 56
    Back Porch - 136

    Vertical pixels (lines)
    Active - 480
    Front porch - 60
    Sync - 3
    Back Porch - 34

    Refresh rate - 60.015 hz

    and make sure the aspect ration is 16:9

    These settings do all the actual centering for me without having to adjust it on the monitor itself. Cheers!!

    I connected the mini to, of all things, my HDTV, opened displayconfigx, and uninstalled all the prior settings. Then I put the settings recommended in the early posts, and it worked! Problem was, the words were too distorted.
    Then I used your settings. They worked, but the screen was way off vertically. So I began messing with the controls; increasing the vertical front porch, while decreasing the vertical back porch by the same amount to make the refresh rate remain at 60.015. I kept playing around and playing around with it until I got the settings I posted. And it works!!
