A video apparatus has a video source with a luminance output carrying a first luminance signal and a chrominance output carrying a chrominance signal, an OSD circuit generating OSD signals and a fast-blanking signal, and a connector for delivering video signals. A converter outputs a second luminance signal based on the OSD signals and a first switch is controlled by the fast-blanking signal selectively connects the converter or the luminance output to the connector and a second is switch is controlled by the fast-blanking signal selectively connects the chrominance output or a circuit generating a constant chrominance signal to the connector.
