  • Why can't I use my dektop lcd for a dvd player screen?

    I picked up a simple adapter for vga to rca, and s-video, but when I plug in my dvd player and turn on the monitor the screen says no signal. The sound is present, but no picture after that. Anybody got anything? Thanks in advance.

    It probably has something to do with the adapter. A simple cable will not be able to take rca and svideo and convert it up to vga. Is the device you have intended to convert a vga signal into rca/ svideo out or is it truly designed to take rca/svideo input and send a vga signal to the monitor?

      It's just a simple adapter to allow me to plug rca's into the monitor itself, so I am sure there is no upconversion going on.

        those adapters are made for screens that have built-in converting for s-video. since your monitor doesnt, you will need the actual converter. theyre usually $50 or more.

            If you're using the VGA out on your motherboard, is it the little yellow RCA port? That's usually video or SPDIF audio so you have to specify with a jumper on the motherboard what you want it to be. Then you have to make sure it's enabled in the BIOS and again in the operating system settings. If all of that is correct, it might show up but it's going to look horrible anyway. What's the size on the LCD? RCA cables are limited to 480 lines of resolution so you're not going to be able to run anything higher than 640x480 and it's going to look like garbage with huge icons and font.

              I'm actually trying to use my desktop lcd as a "tv" for a baby cam.

                You're looking for a scan converter.

                  Oddly enough, I'm now trying something similar. I've got a desktop PC hooked to a large LCD television via a VGA - component cable and it's not working. Anyone know how to get a VGA cable hooked to a television with every other video input?

                    i feed my tv tuner with rca video off my dish network box, for displaying 110" on my projector. it looks nearly as good as dvd since its running enhancements from the video card. thats not to say i dont wish i had a hd video input... and the pc can go up to 1024x768 over rca so text is readable on crt tv's, but its not fun.

                    Maheriano- you probably have a older style of component on that tv then what your pc has. that happens with mine, i have component on the tv but it doesnt work with pc's, just regular dvd players and stuff.

                    there should be some sort of svideo output on your video card... you can use a simple adapter to go from svid to rca is you need to as well.

                            The bandwidth on a RCA cable won't allow for any more than 480i which is 240 lines per frame. I have a projector at home too (running DVI though) and if I hook it up via RCA, it just fills in the extra space with garble. There isn't any higher resolution coming through the line.
