I purchased a Samsung LCD HD and it is supposed to operate @ 1080p and 120 Hz.  I stil can't find a channel that operates at these parameters even on HD channels.The best I found was 1080i @60Hz.  The HDMI cable I purchased supports 1080p and 120 Hz.  What gives?

Your problem is not the HDMI cable - the problem is your HD.....

BUT, there is nothing you can do about it now. Full/True HD(1080p) requires a lot more bandwidth than its counterparts(720p & 1080i) that its just not economically viable for cable companies to use the higher signal. Now with the whole digital conversion coming next feb. *maybe* we will see 1080p, but I think for the "near future" count on only seeing 1080p on your blu ray player

Ok the 1080p issue is understandable now that you pointed it out.  What about the 60Hz vs the 120Hz?  Thanks for your effort.

I have "heard" this is another issue to do with cable company/direct TV - I have HD thru comcast and I can tell you I only see 120HZ when watching blurays, direct tv may be different, call them and ask if your box can deliver a 120hz signal - ALSO, check your tv settings, maybe you have to manually select the refresh rate(HZ) - gotta make that picture look awesome and get rid of that little "blur" effect....

The number after the 1080p is the frame rate. To correct motion blur TV manufacturer has come up with 120hz, it converts lets say 60fps= 60Hz  to 120 fps on fast action scenes by interpolating an extra frame between every pair of frames in the signal so the display runs at 120 Hz so the scene looks smoother.
