I was fooling around with an RGB monitor and an Amiga computer and got the two to work together. After I thought about this for a while, and idea came to me. Is it possible to get an RGB output from a television and connect it to my RGB monitor? Then I thought, if I can fing the right points to make the connexions, could I use a television as a lowgrade RGB monitor. So; I explored. I opened up my 13" Emerson television and began looking for the RGB signals. After taking all the neccessary precautions to avoid electrocution, I checked the voltages of th RGB signals and found them to be 2.8v. Since I don't have a scope, I couldn't find the horizontal and vertical sync signals. I guessed that they may have been at the H and V hold pots, but that may have been wrong. I haven't been able to find a SAMS fotofact folder for my television so I think I'm out of luck. Anyway, I did get (sort of) a picture from my Amiga on the television. It was unsynced, but the colours looked right. Now, my question: Is the NTSC standard compatible with RGB? I remember seeing some info somewhere on it implying that it is. Or, am I on a wild goose chase? Is it possible to extract an RGB signal from a composite video signal? I would like to use my monitor for double duty with a VCR. Any suggestions would be appreciated.
