The demodulator in the VCR may not be as good as the demodulator circuitry in the monitor….thus, viewing the separated outputs (demodulated in the VCR) would show degraddation from viewing the composite output where the demodulation is done in the monitor. The tuner and IF circuits in your VCR breaks the RF signal into sound and video signals. The composite output is the video signal at that point. However, for it to generate the separated outputs…it has to further process that video signal into the separated chroma and luminance signals. That's the output of the separated signals. The monitor on the other hand, either takes the composite signal and does it's own processing to get the chroma and luminance signals…or it gets them directly from the separate outputs. The other reason would be the circuitry in the monitor itself. The composite input circuitry is (in theory) fully matched to the circuitry that breaks out the chroma and luminace signals, while the output of the VCR may not be fully matched (electricaly) to the chroma/luminance circuits in the monitor. In either event, you'd get exactly what you see.
