    Screen issue with Windows 7 - Lilliput 669GL

    I've gone through a tedious process with getting Windows 7 Pro to work on my mini-itx PC system (using the Zotac NM-10-ITX with wifi) with the Lilliput 669GL-70NP/C/T-HB-RV 7" HDMI, DVI, VGA High Brightness, 4 Wire Resistive Touch Screen Monitor.

    My first issue started when I plugged the VGA cable in. Screen flickers (apparently a known issue on the VGA cables); which I checked all connections, nothing fixed it, so I attached an HDMI cable. With this, the cable works, however it is not sized correctly (half the taskbar on the bottom is not fitting as well as both sides and top of the screen, as if Windows is partially zoomed in. Now if this was with an Nvidia card, I'm aware that the drivers make it easy to fix this, however I'm using an Intel based chipset, so I'm out of luck with any Nvidia fixes.

    I also tried DTD Calculator while searching about this issue ( http://www.mp3car.com/vbulletin/lcd-...-graphics.html ), which when I input the values on Calculations, and go into the Registry hack of the program to place the new res into the registry (after reboot process) I DO NOT see any new resolutions that I made, just the standards (when you click LIST ALL resolutions in the advanced tab of the display properties). Is there something I'm doing wrong because it should be visible? I'm literally at a loss, because I thought that program was the answer from all the positive posts, which leaves me now with a VGA connection that doesn't work, and an HDMI connection that doesn't fit right in the screen.

    Please help!
    Thanks,
    Derek

    I have the 669GL 5 wire, but I don't have any flickering issues using VGA. Is this installed in your car already, or is it on a test bed?

    It should be possible to resize the desktop when using HDMI. Look at the Intel graphics app in the task bar and see if you have some sort of scaling setting. I have a micro ATX motherboard that I use for my HTPC that uses the onboard Intel graphics, and there's a way to scale the desktop by percentages - I don't have it running right now so I don't remember exactly where it is in the config app. Sorry.

    I have had zero luck doing any kind of DTD modifications with an Intel graphics chip and this monitor.

    If this is a new screen, I'd see about getting a replacement. That shouldn't be happening.

    Yeah, I was afraid you wouldn't have any adjustments. My HTPC uses an i3 processor, which handles HD and bitstreaming, so it makes sense that those adjustments would not be available on your motherboard.

    Have you seen this?

    I used it to try to make my custom resolutions. I was able to get the custom stuff to show up, but the display never did reflect the correct resolution (and when it did, it looked like crap). Maybe it will help you.

    FWIW, if you return the Lilliput, you could check out the Mini Touch 700. There's a review on MP3car about it, and it gets very high marks. Plus, it has native 800x480 that really works, unlike the Lilliputs.

    I dont think I can return it, I had zero luck getting in contact with Mp3Car's store. I'm really not sure what I can do now. If i can get this screen over stretch fixed, I would be perfectly happy.

    How many emails have you sent to store@mp3car.com? Their customer service pledge says they are supposed to reply within one business day for order support and two business days for technical support.

    Personally, I would not mess with the screen anymore. If I had screen flickering when using VGA, the de-facto monitor standard, that baby would be back in a box heading to the store.

    When you hook up via HDMI, what resolutions are you trying?

    1 - Try updating your graphics drivers.

    2 - If possible, keep power as far away from the VGA cable as possible. If you're on a test bench, this probably isn't an issue. The EMI issue is more likely an issue when you're installed in the vehicle and cords are all together.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    I sent an e-mail just now to that direct e-mail address you provided, so I hope I'll get an answer soon!

    Ok, the overscan disappears when you switch to DVI mode on the screen. However my issue is now the corners (left and right) have a wierd multicolor garble to it (note i switched it with the HDMI to HDMI still pluged in). Now do purchase a DVI to VGA adapter? I dont see why I would purchase a DVI to HDMI adapter if I already have a straight HDMI to HDMI cable. Can anyone fill me in on the gargble on the corners of screen?

    not sure on the garbage on the screen, but i can confirm that the dvi mode seems to display better then hdmi mode.. i tested it briefly with my new 669 screen, and had similar results..(it is very poor of lilliput to include the hdmi connection, but not the tech to scale it correctly)

    i also had the same problem with the vga cable, though it was slightly different circumstances-- i tried using the vga/usb cable from my old 629--that had worked fine--and it caused the exact same problem.. installed the supplied cable and it the 669 was fine..

    so, chris from mo-co-so had confirmed that the cables should be exactly the same, so i can only assume that something about certain cables is not connected correctly, or shorted, and it is only picked up on the 669...

    so mp3car should be able to just send you a new vga/usb cable to correct this..

    maybe PM jenson2000, or post this in the store section of the forum.
