I'm new to the world of gaming on a PVM. I picked up one from a kijiji sale. Didn't realize they used BNC connections so I ordered a couple connectors from the internet.
I did a quick google search and found the below link which says my TV has composite and component(Image from site is same as my TV)

1)-Would Line A and Line B both be two separate composite inputs? And would I just connect the yellow cable to a bnc adaptor and then to the connector in the top left of either Line A or Line B?
2)-Line C looks like regular old S-Video which I don't own any cables for but I hear the quality is a step up so I'm guessing I should change my cables to S-Video wherever I can for any of my consoles.
3)-For the bottom of the panel it says RGB/Component. Would I be able to connect component cables from my console to BNC adapters and then to the TV? From the googling I did, I think I need to use the EXT SYNC port to the right of it as well but I don't exactly understand what systems I'll need it for and which ones I won't need it for.
4)I don't mind shelling money on cables and am looking to get some for my below systems
SNES
N64(I will be getting it RGB modded soon)
Sega Saturn
XBOX-(I own component cables already and have 1 xbox that is soft modded but don't know what cable setup I need to get RGB out of the xbox)
