Need some tech help with Monster Cabling?

post #1 of 14
Thread Starter 
I need a question answered technically and hope someone here can answer it accurately.

I've noticed that alot of Monsters HDMI cables are advertising the bandwidth in gb/s. Is this their way of displaying what a cable is instead of saying that it's HDMIxx compliant or something?

If the wire is HDMI 1.3 compliant then it should very well send a max of 10.2gb/s. However when you look at their wires for the same series at 10.2gb/s .. the longer wires just aren't thicker then the shorter wires which begs the question if they can obtain the theoretical bandwidth since the longer the wire, the more resistance.

Lastly.. on some displays with the 120hz chip, it is said that inorder to utlize the full 120hz then you need an HDMI 1.3 compliant wire. What confuses me is that this feature is still shown on just a simple coaxial wire transferring a digital signal that you can view at Best Buy on the wall. What gives?

Monster is good at marketing, and many people aren't smart enough to do any sort of studying on HDMI.

While many people will tell you ANY HDMI cable is as good as Monster, I'll just say that MOST HDMI cables are as good as Monster.

Monster Cable is the Bose of the cable world.

truth. monoprice has quality cables for LOW prices.

Its not the question of Monster themselves but HDMI as 1.0-1.2 all reach a theoretical bandwidth of 4.95gb/s at 165hz. How exactly is this number obtained?

I know that Monster does go overboard with their marketing just like Bose, but if they advertise on the box 4.92gb/s then you know for a fact that it will produce that much regardless if they are ripping you off or not.

All the numbers Monster likes to float, really mean nothing unless it's a very long run. Here is some information that should help you out:

It's their way of getting you to pay $150 for a $5 product, by spewing out figures and pseudo-scientific terms.

Please, don't buy the hype. Any HDMI v1.3 cable, including a cheap $5 one from Newegg or monoprice, will do what you need.

Because 10.2 is the minimum bandwidth it can carry, not the maximum bandwidth.

You don't. The cables don't pass a 120 Hz signal; the processing is internal to the display.

Isn't Monster Cable the Bose of the cable industry...?

Save your $$$ - Monoprice.com and some ~ internet vendors just as good as many others have said here, and in some aspect even surpass the specs of what Monster Crap is offering, at a fraction of the price.

"Because 10.2 is the minimum bandwidth it can carry, not the maximum bandwidth."

How is 10.2 @ 340hz obtained for the rating? Are we basically taking the resolution and timing it by the framerate and by each color RGB as well as adding in the audio signal since it is HDMI? All I can configure is .. 2560x1600x60*24=5898240000 = 5.8gb/s. What else am I missing? Thanks

anyone?

The 120hz vs cable thing is moot - ramping up a 30 or 40hz signal to 120hz is all done within the TV. If there was a 120hz source, then any HDMI 1.3 cable would send it at that rate.

Resistance only comes into play at REALLY long lengths - this isn't analog, you're just sending 1's and 0's. You don't get signal loss in the analog sense, you either get the data or you don't.

Yes. Here is a summary table.

Deep Color.

deep color is just color that's > 24bit/pixel
or >8bits/color component

Can you do the calculation for me because I simply can not find any proper calculation that agrees with the chart. Possibly there is a special technique for encoded video or somthing.

Yes, which increases the bandwidth. As does a 32 bit computer signal (which is really 24 bit color aligned to an even byte boundary).

It seems to be set up to match dual link DVI, so that you can send a 2560x1600 32 bit 60 Hz computer signal. There's also a blanking interval on top of the raw data, which varies and takes up 5-20% extra. Add it all up and you'll see why you need that TMDS bandwidth.
