I'm Luke Westaway for CNET here at Mobile World Congress 2013 where LG stand, taking a look at some 4K streaming from a phone.
Now, this is a very interesting technology.
What is happening here is you've got a game running on this smartphone.
It's running on an LG Optimus G which is a quad-core device, so it's got quite a powerful processor and it's running an
HD game, but the phone itself is upscaling that to 4K or ultra high-definition as it's sometimes called and they're mirroring that to the television behind me.
As you can see, the result is really impressive.
All the detail on the television is incredibly crisp.
This is a graphically intensive game demo that we're running, but everything up there looks really good and there's not very much latency, you're like asshole, between actions you perform on the phone and what happens on the big screen.
So, this is all happening via LG's proprietary mirroring technology.
It is putting a lot of strain on the phone's processor.
I can feel it's getting very, very warm, but it does seem to be able to handle it.
So, why is this technology useful?
Well, 4K televisions are becoming a bigger deal.
In the next few years, you're gonna be able to buy one for the price that you can get a full HD television for now.
Unfortunately, though, it's gonna be a bit longer before you buy much 4K content to actually watch.
It is good technology in theory at least, but it will take a hefty toll on your phone's battery life, so
it is hoping smartphones become a little bit more battery capable before this technology becomes widespread.
We may not be waiting very long, however, because LG says that in the first parts of next year or possibly even late this year, we're going to see smartphones coming to market that have LG's mirroring upscaling technology built in to them.
