New display cable created makes 8K Resolution @ 120Hz possible

[BiG StroOnZ]

 

 

 

Today, the MHL Consortium (which consists of Samsung, Sony, Toshiba, Nokia and chipmaker Silicon Image) is showing off SuperMHL, a new specification which leapfrogs both HDMI 2.0 and DisplayPort 1.3. It can carry ridiculously detailed 8K video signals at 120 frames per second, with 4:2:0 pixels and 32-bit color, as well as 40W of power and fancy surround sound setups like Dolby Atmos and DTS-UHD. A single SuperMHL source can drive up to eight displays, and you can remote control SuperMHL devices similarly to HDMI.

 

The catch: to get all that goodness at the same time, you need a new cable too, with a new 32-pin SuperMHL connector on both ends. While the SuperMHL protocol works over USB, including the fancy new reversible USB Type-C, MHL president Rob Tobias explained to Gizmodo that you only get four lanes that way. That's enough bandwidth for 8K video at 60fps, or 4K video at 120fps if you want to use USB 3.0 at the same time. Standard microUSB only gives you one lane for a maximum of 4K at 60fps.

 

And since both of those are fairly small phone-grade connectors anyhow, you'll probably want a full-size, six-lane SuperMHL connector anyways. Not like that would necessarily be a bad thing: the new connector's reversible, unlike HDMI or DisplayPort, so you can plug it in without fussing about whether it's upside down when you're blindly reaching around the back of your A/V reciever.

 

Except, of course, that if the SuperMHL connector becomes a standard, that will make for more competition in a field where competition can actually be icky.

Well, I made a post yesterday about ASUS' Rog Swift 4K Monitor and everyone was disappointed that it only had a refresh rate of 60Hz. So until DP 1.3 comes out, those are the resolutions and refresh rates you have to accept. Now DP 1.3 in theory can drive 120Hz @ 4K. However, can Display Port 1.3 do 8K @ 120Hz like this cable? That I'm not too sure off. The only problem with this cable is it would have to become a standard, which would mean that GPU manufacturers would have to put it on their cards (and monitor manufactures on their monitors). Since it requires a connector on both ends to drive up to 8K @ 120Hz. However the flip side is that even without dual-sided SuperMHL connectors, it can still do 4K @ 120Hz. But who knows what the future holds, this just means that the technology is there and ready for adoption. Also note that most of same companies involved in this MHL consortium were responsible for making HDMI a standard.

8K 120 Hz?

[minibois]

This could actually bring multiple displays to a whole 'nother level.

I've seen some posts of people asking how they should hook up 10+ monitors and the answer was usually like "Daisy chain it" or "Get a load of GPU's".

 

This could make it more convenient, but it will take a while before it actually exists in the mainstream (or anywhere in general..)

Balls to the wall.

Is it open like Displayport or are they going to charge everyone that wishes to use it like HDMI does?

4:2:0 - vomit

No point of 120Hz because it's 4:2:0, If it can do 8K 60Hz with 4:4:4 then it's awesome.

[WelshDdraig]

This is quite interesting. The only downside is as the OP said, it would have to become a standard to take off.

I personally have no need for this cable as I'm currently not even past 768p, let alone the 8K that this cable can support. 

[Thony]

Such pixel count, much fps, very wow !

Do it for sub $1500 and 4K will be finally affordable ! (Joke, this wont happen for years ). The cable itself might cost this much...

4:2:0 pixel Hype anyone ?

I would bet if you put a video displayed in 4:2:0 next to one in 4:2:2 next to one in 4:4:4 many will be unable to detect the difference.

Tks is akin to nail gunning your nuts to the wall.

[Toddwjp]

we just need to start reducing the number of cables and slowly phase out older ones, maybe make and sell boxes that have a bank of legacy connectors etc

whatever gets you on...

 

8K @120hz is ballin.

Maybe in 3 years we might get a consumer panel.

Agreed. Looks like if we want 4:4:4 we are stuck with UHD-SDI for now. Not that its a bad interconnect, Just that most pro-consumer tech doesn't have it. And justifying the cost of pro grade equipment for UHD-SDI isn't an economical solution for most people.

because you can so see the difference between 420 and 444 on an average monitor outputing an average movie file

[APrettyCoolWalrus]

Woah...

[Darkman]

Well, 4K limiting cables are now over until we hit like 10K.

[flibberdipper]

Wow. That is INSANE.

Welcome to LTT, where people can tell the different between 120Hz and 144Hz, so of course someone is gonna complain about this doing 8K @ 120Hz @ 4:2:

 

And I'm being a bit of a dick about this. What is the consumer impact of 4:2:0 to 4:2:2 to 4:4:4? What consumer even knows? This is stuff that creators worry about and consider. What the guys working on the next big rendering project. Those kinds of people who strive for utmost accuracy will give a damn.

used to it. still annoys the shit out of me

[totjup5]

Well, that cable should last us a few years.

[Cheddle]

many may not, but an "enthusiast" would - and who do you think wants 8k 120hz? yep... enthusiasts.

 

I tested this with my 4k 60hz screen, toggled from 4:4:4 to 4:2:0 and the difference is intense
