HDMI cable made a difference in picture quality??

I just bought an a 42 inch LG LCD flat screen TV which is has full HD function. I have a HD cable box and opted to use RCA cables betwwen the box and TV. I am getting missed opinions from the cable provider and the LG dealer about the usefulness of the HDMI cable hookup. Does it actually improve picture quality??? If so,how much? and will it also improve non-HD programming??? I have seen several adds from Monster Cable and Audioquest touting their HDMI cables. Monster has one that is about $70; another is about $100. I have seen even higher price tags from Audioquest. All comments welcomed. Thanks Jim

as to your question of hdmi and standard def pics, the real differnce is that most home theater receivers and universal players will only upscale those pics through the hdmi for compliance issues. big differnce in quality.

Riley804, Regarding the non-HD channels, I guess I mean the analog channels like Ovation, American Life Network. Ovation offers interesting music and visual arts programming. ALN offers reruns of Hill Street Blues, St. Elsewhere and Mission Impossible. Elsewhere and Blues look fair to poor; also some digital non HD channels seem slightly out of focus. LG makes a very good TV, so I don't suspect a problem with it. Though, my cable provider often announces it has transmission problems; I live in a high rise apartment building which offers cable hookup which probably further degrades the signal. If I move the TV to the other side of the room, I will be able to take advantage of my Audio Prism power line conditioner which I also use for the stereo system. That might help. I look forward to your answer. Thanks Jim

HDMI has it all over component on my video system. I bought Belden cable from Blue Jeans. The picture is ultra crisp, the color well balanced, and brilliant. The detail fools my cat into thinking those are real birds flying around during Sunrise Earth. She will watch the 80 inch screen for the full hour.

The power conditioner to TV and cable box will make a difference. I would also upgrade the power cords for both the TV and the cable box. PS Audio makes a nice power cable for the small connector often used in video and not too expensive. HDMI the way to go for facility and upscaling SD but, I don't think there should be much of a difference in HD with very good component cables (the ones that come with a cable box are usually not too good) and HDMI.
