With this cable you easily connect your Spectrum 128 with the Scart-port of your monitor or TV. The cable transfers RGB as well as FBAS-Video signal. Although the RGB-signal is the slightly better one, most modern TV´s demand a blanking signal for switching to RGB-Mode. The Spectrum doesn´t have this signal, so unfortunately the FBAS-Video Signal will be the one appearing on most TV´s. This picture is still far better than the normal RF antenna picture, but if you have a TV where you can manually switch to RGB mode, you will see that the colours and contrast are slightly better.
