HDMI cable made a difference in picture quality??

I am really fasinated by the responses I have seen here. Some members claim to see sharper or brighter pictures. Can somebody explain to me how is it possible with digital? I mean, how can cables transmitting digital information apply filter to make picture less or more sharp, or darker or brighter?

You've got me! And I would ask those who claim to have seen significant differences between good quality, presumably spec-compliant hdmi cables if they went back and forth between the cables being compared multiple times, to verify that their observations were consistent. And if they made the comparisons using identical program material; identical cable channels if the cable box was the source; identical lighting conditions; and identical warmup conditions of the tv set.

i'm with macdad, almarg et.al.--i can't see a whit of difference between the generic hdmi cables eforcity sells for 22 cents on amazon and the megabuck super-duper, 48 carat gold, handmade by aryan-demigods cables peddled which retailers peddle so mercilessly. either the cable carries the signal or it doesn't--don't believe the hype.

No difference in picture quality yet the sound from high quality Gold HDMI connectors ($200+), OMG, I bet it would be like night and day for most people here!! LOL

The only way to really test two HDMI cables to see what cable is really better is to freeze frame the HD picture and then compare the two cables looking at the same still picture. Then you can clearly see fine details missing in that still picture and faded looking colors too when you compare Wegrzyn's pure solid silver HDMI cable to other HDMI cables on the market.....

If you freeze frame, it would cause the digital source to output the exact same data per each frame per second. So if there is distortion caused by cable not up to specification, radom noise would be introduced in the form of digital artifacts. They would be so obvious as they would not look like as if there is a digital filter applied to the picture to make it look faded or details missing. Plus, since the data is constant, any artifact would not appear still, as the data stream is constant, any noise would be randomly injected.

Also, HDMI data is checksumed, see HDMI specification:
