Agreed -- HDMI is a disaster and should never have been implemented. The primary purpose of it was to force HDCP down people's throats.

Of course it does. There is no way to transmit 1's and 0's through a cable. You can have a 1 or 0 in a latch, but not on a cable. The signal on a cable is always a time-varying waveform, subject to inductance and capacitance and external magnetic and electric fields. The only difference between analog and digital is that we define some voltage values as 1, some as 0, and some as undefined. The problem comes when the length of the cable stretches out the waveform, or external interference changes the voltage values that were sent, so that the received value isn't happening at the right time, or is in the undefined area. In this case you have a bit error. On digital video, everything happens so fast that there is no mechanism to correct the bit errors. This is when you get sparklies.

The one kind of cable that a ferrite bead wouldn't do anything for is an optical cable.

Hmmm, I was using the DVI cables that came with my Dell LCD.

I then got a hold of another laptop with a ATI X1600 and low and behold, no more sparkles at all on any kind of video playback.
Seems the plot thicken. I am almost half tempted to move my desktop next to the TV. Then hook up the old GeForce 4 Ti4200 to see if the sparkles persist.

I really wish people would do a little research before they make such statements. :rolleyes: All it does is misinform people...
