What are RGB connectors, and are they still relevant?

Episode 928 (55:30)

Mike from Santa Ana, CA

Mike would like to know more about the RGB analog video signal. Scott says that RGB has four connectors (red, green, and blue) plus one for the sync signal. RGB is a professional spec that was used back before HDTVs when CRTs had better resolution and color - especially in black levels.

Then came the Pioneer Kuro and high end LCD TVs that use local dimming. The gap is closing as HDTV flat panels get more mature.
