    At least paying the extra $100 for a capacitive screen saves me from having to get a $6 ribbon extension. haha. Hopefully TFT can verify that sandpaper might allow them to fit with these screens.

    Sand the backs of both of them and they slide right in.

    I have extended dozens of cables of all sizes.
    Might work...I will give it the ol' college try.

    Thanks

    Monitor is 12v. But you should run it off your power supply and not your car because of the fluctuations.

    Have you checked on sanding those cables yet and OSD disappearing TFT? Any Idea when you will be sending mine out?

    Hi,

    is it possible to have PDF files of the dimension of the board + connectors?
    or a datasheet?
    Thanks.

    Brice.

    Ok I received my display today, only had time to try it quickly but noticed that the image does not fit on the screen, all sides showing somewhat off the panel. I will play around with it later on.

    Does the touchscreen need any drivers? I connected it on Win XP and it seem to have recognized and installed the device but the touchscreen function does not work.

    What you're experiencing is probably overscan. It occurs on TV panels. Depending on the screen you can either change the fit on the monitor or adjust settings in your graphics card's control application (unless you use Intel HD graphics, then your stuffed if the monitor doesn't allow it).

    Yes the touchscreen does require drivers. You will need to find out what touch controller it uses. The lilliput I got has an egalax controller, if I am not mistaken. You may need to plug in a USB from the touch controller/monitor to the computer, if you haven't done so already.

    Review of the VGA input resistive touch screen display.

    I received my display almost two weeks ago (quick shipment, it hit the US two days earlier than promised, although I then lost a day due to having to sign for it) and stuffed it in the car and went on a 10 day trip. I temporarily mounted it in a Lilliput frame I had, and that helped out the quick and dirty mount I did. After getting back to town I do have some complaints:
    • (As otherwise mentioned) the old VGA version is really a hack. It has a controller card with connections for an LCD that are not used, but has a daughter card with more components grafted on to it. The cables go from that card to the display, but the flex cable is also a hack. It has a wide spot on it with active components which make it difficult to tuck the controller card behind the display. It's the type of thing I'd expect to see in the lab as a prototype, but not the type of thing I'd expect end users to get.
    • Drivers disk sucks. The drivers on the included disk are dated no newer than 2007, so don't include Windows 7 drivers, and are labeled in Chinese. Derrick immediately offered to find the Win7 driver for me when I emailed about not being able to read the directory entries, but I was able to locate them myself by trail-installing a few things (and failing), then going to the web page that matched the driver name. (Go here: http://home.eeti.com.tw/web20/eGalax...r/W7Driver.htm)
    • No case: I knew this upfront of course, but not having a case at all does make mounting harder. No easy way to hold the display and controller boards, and no place to put the buttons board. With the tiny flex cables, I was very concerned I'd break something (as I think I did to my Lilliput screen).
    • Resistive touch screens suck. It makes the display look a little milky and no multi-touch (zoom is a PITA), really a downer when you are used to an iPad.
    • Touch pad and drivers are not 100%: I've had a few times when it powered up and Windows 7 refused to recognize the panel. When I rebooted it was fine, but it is impossible to reboot unless you carry around a spare keyboard (which I did). Crawling in to the trunk to unplug/replug the USB might have worked too, I'll try that next time.
    • Not really sunlight readable. Maybe if you are close to it, but not when you are driving down the road and trying to read the NAV. I had to take off my sunglasses and lean in to read it many times, and I still have 20/20 vision. It is better than my old Lilliput, but IMHO, not good enough.
    • You may have to really muck around with the video driver to get your system to do 800x480 at 57 hz. I did, and it was not very easy. I could not get the display to work well at 1024x768 which is what I really wanted.


    I do want to say that Derrick is very responsive and great to work with. I am having an issue with the LCD washing out the blue color in to the adjacent pixels, and I suspect he ran down the issue (dirty pins on the ribbon cable). I'll know for sure when I can pull it out and clean it off.

    So in summary, go for the capacitive touch screen on the HDMI board. Don't even consider the original, unless you were desperate for something before a big trip as I was.

    And as for Centrafuse, I've got a whole other list of complaints for it.
