I will try that but what if the charging system is the problem.What would i do than?I have tryed it in the dc plug with the motor off and get the same results.Dont no if that would be the same concept.

I don't know how your vehicle operates. If a key has to be turned to enable the 12v port, it probably powers a fuel pump, relays, or any manner of things. If the monitor interference is less with the vehicle off and the monitor powered, than on, that would indicate interference from the vehicle (pretty common).

One solution to eliminate certain frequencies of interference is a ferrite. Cheap and easy solution to try.

A source of monitor problem might also be poor connections, bad wire, or inductive noise from a nearby device.

get a choke wired in line like for a cb radio will smooth out the dc voltage

Thanks for that info.I will try that if the battery thing works.Do i just look up wire choke or how would i google it?Is this the kind of thing your talking about?http://www.ebay.com/itm/WORKMAN-CBNF3AXX-CB-RADIO-STEREO-POWER-NOISE-FILTER-20-AMP-3-PIN-/111324236718

Would i need a 10 amp or a 30 amp?

Will this work http://www.ebay.com/itm/NEW-Workman-Bandit-NF40-noise-filter-20-AMP-CB-sterio-noise-filter-NEW-/120881946312 or is this more like it and if so where does the blue wire go http://www.ebay.com/itm/PAC-NF-10-10-AMP-DELUXE-POWER-LEAD-FILTER-/310832213278?_trksid=p2054897.l4275

You may be picking up interference from a power wire ran either across the video wire or either next to it. I have ran into this problem at work. If the video wire is not an insulated wire, it will pick up the slightest bit of static from any wire that produces electricity. It can be very frustrating.

I have a red line in mine

If you were not running inverter/converter, overhead lights, etc, it may be a bad monitor. I'd still try it hooked directly to a battery that is not connected to anything else. If it still has the problem, I'd be asking for a replacement.

I did have the generator on so maybe that was it.I will try the battery thanks.Also i dont know if the two ar related but if i roll up/down my power window the screen will turn completely off and show black and white lines rolling.

I tried one on my last truck and same thing, it said in the instructions that there would be interference from a diesel engine, I just didn't believe them, removed and returned.

Was it wired or wireless?Mine is wired.

It was wireless...
