Ah well, VGA uses RGB but if your monitor is a true RGB, then what you want is to do is convert this:BUGBYTE- your link is not to a RCA to RGB adapter. it is for a RCA to Vga. they are totaly different. i still stand by my statement there is no such thing. but thanks anyways.
In which case you can use this device to do it.
Perhaps my use of the term adaptor suggested that there is a magic cable to do this. You are correct that there is not. However, that does not mean it cannot be done. There is almost always a solution for something like this.
