Hi guys!


I am in the middle of making the final decision on whatever to go for a JVC X30 or Epson Tw9000 projector - in this case, I need to buy my first 10m (I guess about 32ft) HDMI cable.

- Had anyone experience more or less crosstalk and flicker in 3D, when using a better or worse HDMI cable??

^^^

same rule for 3d as for 2d with hdmi cables... it either works, or it doesn't...

the hdmi cable cannot affect crosstalk/flicker, there is no causal relationship that exists...

The HDMI organization reccomends that a High Speed HDMI cable with a max length of 25 feet be used if the 3D signal is a packed 3D signal from a 3D disk player of from a PS3. If the 3D content is from cable or satellite then a standard HDMI cable can be used. For 35 feet I suggest that you try a stndard HDMI cable with thick(high gauge) wires. Hopefully you will not get any signal degradation that can cause dropped frames, and/or stuttering ifyou are using a PS3 or 3D BR disk player.

I am currently look at 2 higher end cables:

One is from ViaBlue, has 26AWG silver plated OFC wiring.

The other is Real Cable Infinite which is 24AWG OFC, but no silver plating, as far as I can tell. As I have been offered a discount on the Real Cable, the price is identical for the 2 cables in 10meter runs.


So in this situation - go for silver plated or better wire gauge? :-D

Did you try Monoprice Cables they are one of the sponsers of AVA forums and reccomended by many of us on this forum?

Did you notice he is in Denmark? The boutique cables may be cheaper for him than monoprice after shipping is added.

Well, theoretically because of skin effect and the greater conductivity of silver, silver plating would be advantageous. However, one can get the same effect by going to larger wire. And it really depends on the way the plating is done whether the silver provides any improvement in conductiity at all. Sometimes, it is worse than no plating at all. IIWY I would go for the larger gauge unplated wire.

FWIW there are things much more important than resistance for HDMI performance, like skew and crosstalk.

Even a decently made inexpensive cable should do the job for you as well as the ones you are considering.
