I have just connected my Mitsubishi HD1000U with a new 24 gauge 25 foot HDMI cable from Monoprice.com. I am trying to determine if the cable is working properly or not. The picture looks good, but I seem to see more picture noise than I had with the previous Component video cable. I have read that a bad HDMI cable will produce picture noise in the form of Starbrights or Sparkles. What are HDMI Starbrights or Sparkles and what do I look for to determine if the cable is defective or not?
Thanks,
Hugh

More likely to be the video source, not the cable. A poor signal or a highly compressed signal will introduce artifacts. What is your signal source and do you have access to other equipment?

Thanks for your quick reply. I am outputting from a Toshiba HD-A20 HD DVD player to my Mitsubishi HD1000U projector.
I have been testing the setup this morning going back and forth between the new HDMI cable and my old component video cable. I have discovered that part of the HDMI problem has to do with the output resolution setting I choose on the HD DVD player. For some reason when I set the HD DVD player output to 720P to match the projector native resolution I get a vertical band of noise on the left side of the image. If I change the HD DVD player output to any other resolution the noise goes away. I don't understand why this is happening. Does anyone have any idea what is going on?
Thanks,
Hugh

Actually, it probably IS the cable. Go to this site: click here (http://www.vizionware.com) and check out their active cable and the information about how HDMI gets shredded causing sparkles and loss of detail.

He just said it was fine with other resolutions from his Toshiba but not 720p.
