I've got a lilliput, just a simple composite input plain old lilli. Not a VGA or a Touchscreen or anything. Now I'm pleased with the screen but when the DC-DC converter is a little sub par (It's a car converter.) So the issue of screen distortion arises when the power comes from the alternator. When the ignition is at ACC everything is fine. Someone told me that I needed a power line noise filter, but I don't really know what I'm looking for in that regard. Also I think will probably buy a better converter. My question is if anyone can reccommend a power line noise filter or at least give me an idea where to start my search for this particular application. My second question is whether I can just solder the lines that come to my cigarette lighter adapter to those on the converter and not damage anything? Thanks for your help guys.
