(1) sudo raspi-config is for configuring only the audio or for other things also.
(2) The video cable will have 1 male plug on one end and 2 male plugs on the other end
OR it will have 2 male plugs on both ends ? Because i mostly see cables with one plug on one end and two plugs on the other end.
I also came to know that on CRT monitors there is a lot of flickering (perhaps due to difference of refresh rates) can we configure that too through sudo raspi-config ?
No problems asking, I'm here to help.
(1) Raspi-config (the config.txt file) is for a whole lots of configuration issues, its a replacement for the "BIOS settings" in a classic PC.
(2) it doesn't matter if the actual cable has two wires, as long as on both ends of the same cable both connectors are male. You can ignore the unused halve. Just one caution, these cables are normally "double", because they are used for audio, that means that for video their quality might not be optimal, but they should work. If you can find a single cable, with yellow connectors on both ends, it will probably give a better picture quality.
Yes, the config.txt (editable with sudo raspi-config) file also controls the type of composite video that is generated, and normally it uses the American (60Hz) NTSC system, if you have another system then you can make a better choice with config.txt for example the european 50Hz PAL system, but also some specialised versions, for japan, and South America. With the right version, you will also be able to get color, on a color TV.
