I recently bought a new monitor that has a built-in speakers and TV-tuner. I believe speaker works on TV mode because the static image produces sound but when I use it for PC it doesn't work. It doesnt have a dvi port so Im using an HDMI-port which I know doesnt carry sound.It has "component-in" video ports(RGB) and an audio port(WHITE/RED). Im not sure what wires I need so I need a little bit of help
