In preparation for a display upgrade, I checked my NTL digital box to make sure that it could output RGB as well as composite. I have two NTL boxes; one has the option of outputting composite and S-video, and the other has the option of outputting composite and RGB.... very strange. Both boxes look exactly the same. In the one that can output RGB I selected the RGB option for image output. A scart lead from this NTL box leads to the composite input on my Rotel receiver. When I chose RGB as the output type, I could still see the image as it was before..... very strange again. Can anyone explain this? I aim to convert the scart RGB output from the NTL box to component or VGA, and I hope I'll be able to do this. Thanks.
