I have two 22" Vizio ' s in my TT that both have wall warts rated at 12vdc output. I made up a cord and run both on 12vdc and they work great. Both have vga input, rca av, composite, and hdmi as well as cable input. I connected both my laptops and run both at 1080i. They both perform very well. One of the 22" however does not have audio output to external speakers. Did not realize that when I purchased it. I just run audio out from the pc and it works fine. Other than that, the flat screens both are capable as 12v monitors and work fantastic. I paid $130 for the last one at Sam's club. Aslo, Harbor Freight sells a solar accessory kit with various dc plugs. One of the plugs is a cigarette lighter plug with a round jack on the other end. Guess what, it fit the tv ' s and the polarity was correct. I bought another after finding the ready made plug and stashed the hand made plug for other uses.
