  • Rolling Verticle Waves in Lilliput VGA LCD

    Hello,

    I need some help please. I have 'd already and haven't found anything that would lead to a solution for my problem.

    I just got my Lilliput screen. I hooked it up to my EPIA m 1000 mobo and plugged it in to the wall with the factory AC adapter. After a couple minutes of playing with it I noticed at roughly 30 second intervals (or less..there was some sort of pattern) the screen would get distorted with a small verticle wave disturbance. This is very annoying BTW.

    My resolution was 800 x 600 32b color. The EPIA m1000 was powered by a regular AC - DC Power supply plugged right into the wall.

    I was like WTF so I plugged the VGA cable into my laptop's vga out and noticed that the waves went away at 1024x768 resolution 32b(default setting). I changed my laptop video card (with lilliput connected) to 800 x 600 @32b color and the wavey verticle pattern reappeared.

    I read a few people that had a simliar problem but there was never an answer to these posts/threads saying that yea ____ fixed the problem. Most people recomeded the grounding.

    How do you ground a motherboard? From the screw holes run it a good metal contact on the car?

    Could this be a driver issue. I installed the factory shipped drivers from VIA.

    Could it be that i need a better video card?

    I cant say for sure that it is the lilliput screen but it appears that it does not like 800x600. Am i forced to upgrade my graphics card.

    Has anyone else gotten their Lilliput Screen working at 800x600 with the onboard video card that comes with the EPIA M1000?

    Has anyone else had any experience that could shed some light on my situation?

    Thanks in advance.

    Yes, it works with the M10000. My screen had some vga issues, hazy wavy screen, then I found out it was the din plug that comes out of the lilliput and connects to the vga/usb cable. It wasn't making a very good ground connection. If you squeeze that plug really hard does it get any better? By squeeze I mean pinch. The problem that a lot of people get is that the grounding shell is not making good contact.

      ddogg_777,

      I will give that a try tonight. Were the waves verticle and would phase in and out?

      What resolution/color depth/refresh are you using?

        The whole picture was just bad, it is hard to explain, the colors were off and it was hazy. I am not sure yours is the same problem or not. My settings are 60hz 800*600 at 32bit color.
