  • i need help

    ok i have a double din screen in my car what i want to do is hook up my laptop so that it will display the desktop on the screen and mount a touch pad in the console so i can put the laptop in the back and listen to my music on it. my question is is it possible to do this thru a usb port where i have 1 cable to plug into my laptop and have video and audio converted into rca

    They make usb->vga adapters and also usb sound cards and usb touchpads. It will all be very choppy running with the video too.

        Outward conversion is a video card. That simple. If you want it in USB form, then get a USB external video card...

        And no the wii doesnt do usb to video output. Not all tiny connectors are USB. They just use a connector and put their own info over the line. There is no such thing as a video adapter "cable" that will go from usb (a data standard) to vga (a video standard).

        If you want more than 1 cable to connect each time, then get a "pc to tv" converter. But the quality will crap crap crap. I would not even think about doing this unless you are getting a VGA quality screen.

          You need to tell us a little more about your screen and laptop. Does your screen have VGA inputs? If it only has RCA inputs than your quality is gonna suffer no matter what. Does your laptop have S-Video out? They make cables and adapters that go from S-Video out to RCA.

              If that's all you're trying to do, cables with s-video connectors on one end and phono (A/V) connectors on the other are cheap and plentiful; most decent-sized supermarkets have them. Be warned though, the video quality will not be good.

                Why only 1 cable? The easiest way to do it is to do what Grrrrrrrrrrrrrrrrrrrrrrrrmachine said. Buy the cable at walmart or bestbuy or something. It will be good enough for watching movies and playing music, anything past that and you're gonna be guessing whats on the screen.

                    Yes but it needs to go into your audio jack on your laptop. Those cables are really three cables in one. One goes to from S-video to RCA video and the last two go from your audio jack to two RCA audio plugs (right & left)

                        Just to be clear here, svideo contains no audio.

                        But you can buy a cable that as reagler said has multiple cables wrapped inside it, which has video and audio. But again on the laptop side and the headunit side, you will be plugging in more than 1 wire each time. Also the touchscreen will not work, and again the video will suffer big time. Hook your laptop up to your tv using the svideo cable. Look at how it looks, and you will believe us.

                            From what i know, USB video cards aren't cheap and they are bottle necked because USB can only all so much bandwidth to go through it. They make those for people who don't have analog signals and only digitial. But i also have never used them so who knows. If you get that cable I posted above, all you have to do is disconnect/connect the s-video and audio cables. Using the usb video and audio connector seems like a more complex and more expensive way to go. Plus you would have to use two usb ports, one for video and one for audio.

                            If this is really the course you want to take, then have at and if you get it to work, write a tutorial!

                            p.s. toaster, its reegler, not reagler its ok though, i forgive you
