On my TV the HDMI cable was much worse than the component cable. That said the HDMI cable was a freebie from the cable company. Also maybe there was something wrong with the HDMI output on my cable box. I would try both and use which ever is better.
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
