    What is it like with Windows 8.1?
    Like I said, my issue was my 669 was on the way out. It would loose power, or come up "No signal" when there was an image on screen and powered on. I haven't had the desire to upgrade my HU to 8.1, so I have no idea how it would look. I'm shooting to do the upgrade to w9 eventually.


    Some updates:
    • Auto brightness seemed a bit annoying when I payed close attention this morning, it switched brightness to frequently for me. I am going to reach out to lililput and see if there is some setting I can change to slow the response time down or something.
    • Re-positioning the monitor seemed to help quite a bit with glare, I've seen a significant reduction my taking the screen from a ~60* mounting to ~75* we shall see how it preforms this afternoon.

    So it looks like the touch panel is integrated in the glass that spans the entire front of the monitor, much like a tablet.

    This would make it impossible to remove the LCD from the housing and making a custom bezel. It also means it has a larger installation footprint.

    Not a bad price though!

    Hi thank you raggedrebel92 for your review.
    Do you aim to open this lilliput to see what is inside? If yes, could you take pictures?


    It seems that I found a source for the capacitive touch screen.

    Unfortunatenly, I have issues with the touch screen

    explaination :
    The parcel was blocked at TNT. I gone to take the parcel.

    I started test of the touch panel. There is a big issue on this product.

    The touch panel do not work immediatly after USB pluged in. Drivers are well installed but it does not work at all.

    After a lot of manipulation, touching the screen on both sides, it started to works perfectly. I can see my 5 fingers on the screen.
    But when I unplug and plug again the USB cable, it stop working again.

    So I manipulate it during a long time and then it start working again until I unplug USB and plug in again.

    ==> It can't be mecanical issue because when it start working (after a long long time of manipulations) it still working very well when i move the flexible PCB.
    ==> It can't be drivers issues because I tried on 2 different PC, one with windows 7 and the other with Windows 8.1. The symptoms are exactly the same on both PC.
    ==> For me, it seems like a firmware issue of the touch screen.

    WHERE I BOUGHT

    With Black frame
    http://www.aliexpress.com/item/7-inc...716534901.html

    Without Black frame.
    http://www.aliexpress.com/store/prod...849688807.html
    or
    http://www.aliexpress.com/store/prod...849119434.html

    But right now, i advise NOT to buy these spare parts because my tests are KO, touch screen have FIRMWARE issues in this version.

    How many inputs could you have with the touche screen.
    With my faulty, I could have until 5 fingers input.

    If some one could open this Lilliput in order to see what's inside.

    After plugging in the USB, try to wait about 20sec before touching it and then try. I have noticed that some touchscreens need time to adapt to the environment before you can touch them. Touching them in between this period could mess up the auto stabilization process. This lengthy time is because its probably waiting for the LCD to start up and be stable. LCD causes interference to the touchscreen and that's why it needs to learn and settle.

    Another thing looks like it works good touching the other side. Flip it around and see if it works reliably when its backwards.

    Interested to hear the results..

    Hi Customgadz,

    Unfortunately, waiting after plug into USB of touching the other side do nothing.
    To make it work, I have to touch both sides in the corners during a long time and with several fingers and some time it start working.
    I took a lot of time and I can't reproduce easily.



    here is the PCB :

    I am waiting information of the seller and hid engineer. The message I received :

    This problem to our engineers, he said this touch screen short time power off reset. He will cooperate with you to modify the software, and then send you to download software.

    The 779gl would've been a nice screen 3-4 years ago. It's ridiculous that Lilliput is still putting out 800x480 panels in 2014, especially when you consider the minimum requirement for Windows 8 is 1024x768.
