Lilliput ghosting...

**wagonerd** · 03-23-2005, 04:37 PM

I've looked everywhere to find the answer to my problems but to no avail...so here goes...

I bought an in-dash lilliput from digitalww for my install. Before I installed it, I tested the monitor just using the VGA cable that comes out of the back of the unit. Everything looked fine. As soon as I connected a VGA extension cable the image had a weird ghosting going on. I've read that the fix to this is to extend the 9-pin cable instead, but my 9-pin cable only has usb/aux ins. Any ideas? Do I have a bum VGA extension cable or what?

The other problem I'm having is the common flickering problem. I've tried bumping the refresh rate from 70Hz-85Hz but that doesn't help. I'm thinking it may have something to do with the fact that I'm powering it from the power cable that goes into my head unit. Any ideas? Oh ya, and I'm using a laptop as my carputer so powering it from an Opus is not happening.

Thanks in advance!

Thanks Josh...I'll have to give that a shot. The other strange thing is, I first tried a 10' (or so) extension cable and noticed the crappy signal, so I bought a brand new cable, and the same thing happened...

The flickering is kinda hard to explain, it's not flashing on and off, it's more like lines across the screen that are lighter than the image that's displayed. But they aren't constant...it's sparatic, but I have noticed that they tend to respond to bass when I turn the volume up high. I'll see if I can get a picture or video or something tonight.

the "flickering" sounds like a grounding issue. I had the same thing happen before I used a common ground for everything that was connected together (computer, monitor, and HU).

If I remember correctly I think I have the ground spliced into the HU ground wire. Could that be the problem?

The laptop is powered from an aux cigarette lighter in the trunk along with an adapter for plugging the laptop into the cigarrette lighter. I grounded the aux adapter to the same as my amp which is a direct ground to the chassis. If there's another (better) method for powering my laptop, I'd be open to options as I'm noticing that the power doesn't really charge the battery, but it does help sustain the battery when the car is running.
