120 Hz HDMI Cables??

post #1 of 35
Thread Starter 
I was at BB tonight buying a new TV: Sony KDL52XBR4 52" LCD Panel. The salesman told me I would need to replace all of my HDMI cables with ones rated for 120 Hz, especially those going to my Blu Ray player (Panny DMP-BD30). I've always been of the mind to never pay "monstrous" prices for HDMI cables. Is what the salesman told me true or was he feeding me a line of crap?

Thanks

He's feeding you a line. A decent HDMI cable should suffice. Monoprice.com sells decent HDMI cables for cheap.

I'm not sure what's funnier, if he did know he was feeding you a line of crap or if he didn't.

So many things wrong with this one.
1) There is no such thing as 120Hz rated cables.
2) Even if there was your HDTV only accepts 24p & 60p over HDMI. While it displays at 120Hz it still only accepts a 24Hz or 60Hz signal. There are no consumer grade HDTV with a 120p input. Period.

3) Even if there were 120Hz cables (there aren't) and your HDTV accepted 120p input (it doesn't) no BD player has 120Hz (120p) output. Since content on the disc is 24p there is no reason to output it as 120p. It is output as 24p (using less bandwidth than 60p) and your HDTV applies a 5:5 pulldown to 120Hz.

Someday there may be sources (PS4, xbox 720) with an 120Hz output and someday there may be HDTV with 120p input but even those would just need an HDMI cable.

Snake Oil at its finest.

Thanks for the quick replies. I'm just going to try my existing cables, and if I have any issues, I will go to monoprice for the replacements. This is what I was thinking all along - just wanted confirmation - thanks again.

Total line of stuff. When you buy your cables from Monoprice. Just be sure to buy the new 1.3 that they have now for the speed and Pin 7 (I think thats it) that you will need later on.

The 1.3 label just means they have been tested to support full 1080p, it does not mean your existing cable will not. As for PIN 7, you are maybe caught up a little in the hype yourself. HDMI cables all have 19 pins except for a higher definition version that has 29 pins.

The HDMI Specification has expanded to include three connectors, each intended for different markets.

The standard Type A HDMI connector has 19 pins, with bandwidth to support all SDTV, EDTV and HDTV modes and more. The plug outside dimensions are 13.9 mm wide by 4.45 mm high. Type A is electrically compatible with single-link DVI-D.

A higher resolution version called Type B is defined in HDMI 1.0. Type B has 29 pins (21.2 mm wide), allowing it to carry an expanded video channel for use with very high-resolution future displays, such as WQSXGA (3200x2048). Type B is electrically compatible with dual-link DVI-D, but is not in general use.

The Type C mini-connector is intended for portable devices. It is smaller than Type A (10.42 mm by 2.42 mm) but has the same 19-pin configuration.

Let me guess, it was the Monster Cable brand that cost $150.

I have never paid more than $4 for an HDMI cable and have never had an issue, even with 1080p.
post #11 of 35
I'm using cables that I bought from monoprice more than a year ago, before HDMI 1.3 was even released. I have zero problems using these cables with my 1080p TV and bitstreaming DTS-MA to my Pioneer 94TXH. They aren't "1.3" rated cables (which I suspect are the exact same cables branded with the 1.3 moniker) as many companies are advertising today, yet they work fine with all the advanced video and audio options that are becoming more common. My point is, you don't need fancy expensive cables, just good quality cables. Monoprice is so cheap that by the time you will need something else, many years from now, you won't be sweating the $5 you spent on a cable.

Ha ha ha. Awesome. I used to work for the BB competition in red shirts while in college...every now and then, my department manager would call and ask for things that didn't exist like a tape deck with optical output just to show us why training was so important. Sadly, most of the time the answer was, "Yea, we've got that". My personal favorite was when a customer came in trying to figure out how to hook up her new surround sound system that she bought at BB, which consisted of a stereo receiver and a surround sound speaker package. Apparently the store associate told her to just twist a bunch of the wires together and shove them in the speaker output. Luckily, she came to us for a second opinion.

This is just sad but it shows the markup they have on those cables.

It WAS a monster cable, but for a 10 footer it was $219. Unbelievable. And of course, I'd need two - one from the BD player to the AV receiver, and one from the AV receiver to the TV.

I would expect nothing less from BB.

Another amazing BB story. I visit BB often and I listen to all kinds of nonsense from some of the sales people. So many customers ask for advice from these inexperience people and they accept it without question. Let the buyer beware. I have used many of the Monoprice cables for myself and friends over the past year and a half with no issues. We have saved a lot of money. I find it sad to see hown many people really get ripped off by the snake oil being sold.

Ya, I went up with my friend a couple years back to help with car stereo purchase and the salesperson tried to sell him extra heavy cables because the "bass box will be in the trunk and tweeters up front, so the if you use the thicker cables the sounds will all get there at the same time." "If not, your bass will lag behind the treble"

Hmm, I said, "correct me if I am wrong but doesn't electicity travel at nearly the speed of light? The car is what 12 ft long? I doubt we will notice the .0000000000000000001 of a second regardless of cabling used, let's risk it!"

Sheez! Unreal!

Which one is the Data Pin?
post #19 of 35
All of them are associated with data of one sort or another, except for the power pin and the "reserved for future expansion" pin; what kind of data are you asking about? I'm very familiar with the cable spec and can probably answer your question if you can be a bit more specific.

Too funny. I always wonder if these people are lying or just don't understand it themselves.

I worked at a hardware store a while back. Sometimes when someone would ask where the Crescent wrenches were I'd ask them if they wanted metric or standard.

i work for a best buy during the offseason (work in minor league baseball) in the HT department and i recommend monoprice.com to about 75% of the people i talk to. it depends on the person, some people want the cables asap and dont care about the price, so they dismiss my suggestion, but most appreciate it. but yeah, dont generalize on BB employees before you get in the store, a few of us know our stuff. i guess im defending myself more than best buy, i dont particularly care for the place either.
post #23 of 35
I'd hope that every HDMI cable is rated at a little higher than 120hz 340MHz=HDMI 1.3. That and the guy obviously didn't know jack about what 120hz actually is regarding televisions.

Our MHT guys know a fair amount more than expected (management holds them accountable for knowing their **** and we've got a few enthusiasts in the upper levels), but depending on how its reinforced you'll find things like (at our store) the occasional employee using lines like "are you router certified" in order to land some in-home installation. While your average person doesn't know jack about networking, when you run into someone who knows what they're talking about it kills the credibility of the brand.

The sad thing is it works on other people when it comes to selling, leading to praise by management or supervisors who don't know any better themselves for good performance. Unfortunately it just gives every blue shirt a bad name.

Thanks for the tip. That site looks like they have 3ft HDMI 1.3a "gold plated" cables for less than $5. That's less than the sales tax I'd pay for Mon$ter Cable$.
post #25 of 35
Same thing happened at CC. He kept telling me I would need 120hz-certified cable. I just nodded and said no thanks. But his insistence made me hesitate and wonder, so I got online to check it out (just in case he really did know what he was talking about). So for many (most?) people, I'd imagine they'll just take the word of the sales person. I guess companies figure if you're already spending 1000s on TV and player, etc., you won't mind paying a couple hundred dollars for cables. A real shame.

Got told it too while I was shopping. Glad to see it is BS.

Any HDMI Cable that is 1.3 Highspeed and has a bandwidth of 10.2 GBPS (Gigabytes per second) will pass 1080p at 120hz. To say any HDMI will pass 120hz is wrong there are many cables out there with a rating of 2.2 GBPS at that band width you can only handle 1080i at 60hz. BB has all of this info. If you question a salesmans judgment you can have them call there specailists and get the real facts. They do carry more inexpensive cables that will support 120hz.
post #28 of 35
I too recently purchased a Sony 52" LCD (KDL52W4100) and got the same spill from the sales rep from BB. "You must buy this HDMI cable (pointing) to receive full 120hz blah blah blah." I told him I would find one online cheaper than $150, so no thanks. I mean, you've got to be freaking kidding me trying to push another $150 on me after I just spent $2400 on a Freaking TV! Greedy bastards.

Anyway, the story goes (although this may not be the case 100% of the time) is these guys (and girls) get hired there not really knowing much. Sometimes they're like me and "think" they know a lot, but when they finally get in the world of electronics and computers, get their eyes opened wide. I started working at CompUSA @ 19 (about 8 years ago) and I'm not one to go telling somebody something that I know isn't true, however I was unaware that half the time I was telling people things that I didn't know was false.

What happens is a manager or a "more advanced" team member will tell you something to this effect, like "Your surge protector must be 1028 Joules", and you, the ignorant one, says "Oh, really, I did not know that". Now you are passing that "knowledge" on to anybody you talk to. This is just one example (still not even sure about the truth on that one), but the cable thing is a bit rediculous. Even though I didn't know everything mentioned in this post, I did know that any cable bought at Walmart, Circuit City, BestBuy, hhgregg, etc. were all marked up over 800%. I remember one of the last things I bought with my employee discount at CompUSA was a SCSI2 cable that retailed for $74. I got it for $4 (cost).

It's really sad how high they have these marked up and even with the number of places on the web to buy these, they still have not brought these prices down. It's just sickening.

I'll be honest though, I have had some guys tell me "Here's the cable you need, but you can get it online for much cheaper." I like these guys and stores listed above need more of them.

ummmm... no... ratings aren't a "maximum limit"... and your cable doesn't care what refresh rate your tv is using...
