A8 chip on Apple iPhone 6 and Apple iPhone 6 Plus can support 4K video playback

A8 chip on Apple iPhone 6 and Apple iPhone 6 Plus can support 4K video playback
Developers of the Mac app WALTR have made an interesting discovery. First, let's get you familiar with WALTR. With the app, you can upload unsupported video to your Apple iPhone or Apple iPad such as FLAC and MKV files. It seems that the developers of WALTR have discovered that the A8 processor used on the Apple iPhone 6 and Apple iPhone 6 Plus, will support 4K video playback.

The developers behind WALTR made this discovery despite nary a peep from Cupertino. Unfortunately though, the 4.7-inch  iPhone 6 screen has a resolution of 750 x 1334, and the resolution for the 5.5-inch iPhone 6 Plus glass is 1080 x 1920. This means that the 4K video playbook capability is lost on users of these two new iPhone models. In addition, the size of the these 4K video files would so large that you would be left with greatly diminished storage capacity.

Apple might plan on using the A8 chip for Apple TV, which currently uses the aging A5. If so, there is no question that an A8 powered version would support 4K video.

You can click on the video below to see the evidence that the A8 can support 4K video playback.

There's ZERO devices across all mobile platforms that can display 4K playback.

Um, not unless you use an MHL 3.0 adapter and output to a 4K display. Note 4 does that. Below is the Samsung MHL 3.0 adapter link. I have one and tried it on a Samsung 4K TV at the local TV store demo unit (to see if it actually worked and outputted 4K video and it did output 4K video). I wasn't going to buy the TV (still too expensive for me and waiting for more 4K content) but the store workers let me try it for kicks to see if it did work and wanted to see it for themselves. http://www.samsung.com/us/mobile/cell-phones-accessories/EE-HN910FWESTA

And how many people are going to do that? He clearly meant natively on the device's screen.

He never mentioned the display of the phone itself. So how did you know what he actually meant? I'm only reading what he actually wrote.BTW there are plenty of devices that do support 4K playback, maybe not on the built in screen, but definitely do support 4K playback. BTW who cares how many people do that. I know I do that. For me, video playback on 4K would be of interest TO ME. For example, one day if and when I do own a 4K TV, when I shoot videos on my phone in 4K, I can show it to people on my 4K TV. Great for when I show family movies to a lot of people at my family gatherings.

Don't mind him. He is jealous because he paid more for hos cheap bendy phone that can shoot 4k, but doesn't.

Are you being serious right now? You blind fanboy idiots can't see anything beyond your biased notions. Check out the device I own & the devices I have previously owned. Have fun eating crow, dumbass.

Well previous iPhone record full hd video and you couldn't see it on the screen, did you say anything about it? In fact how far back have iPhones been able to record full hd videos?

47. g2a5b0e unregistered

Get your head out of your ass, dude. I'm a huge Android fan & the same thing applies. My Note 2 recorded FHD with an HD screen. Stop being so stupidly biased.

Actually this is what I'm looking to do in a few weeks. I'm purchasing a 4k TV and will be getting the best one that is within the 55-60 inch range for my entertainment room. I will most certainly be purchasing this adapter

Definitely get the adapter. I even hooked up my phone to my TV with the adapter, use a sixaxis controller from my PS3, and played games like a console. Did it with the GTA Vice City and San Andreas.

You missed the point but good job. I though 1 sentence was easy enough to interpret.

Not true, snapdragon 805, tegra 4/K1, exynos all can. They all demoed it at ces at the beginning of the year.

On their 4K screens? No. 4K video files are brought down to native display resolution. Good job.

Google rk3288 and am logic s812. On android boxes with the latest version of HDMI 4k is already possible. Heck mine plays 1080p hevc/265 just fine, but couldn't find a test 4k file yet...

Whoops I sure did. But it doesn't matter because it's so obvious I'm being sarcastic lol.

But still. 4k video playback on a 2k/4k display is much better than 4k video playback on a 720p/1080p display. So these clips would be much more detailed on a Nexus 6 or Note 4

i think it could read 4k since the Sound was aac if the sound was DTS or FLAC or Master DTS TRue HD it would flikers and trchez hehehe

But it's not enabled because there is no point to watching 4K videos on a mobile screen because anything above device resolution is a complete waste of bandwidth and storage. Duh.

yeah because I guess I can burn it to a dvd and play it on my 4K TV? Or move it too a USB and play it on my tv? Since the Note supports SDcards space isn't a huge issue. Its only an issue for iPhones users.

Not an incorrect statement, but since there are no consumer smartphones or tablets available with 4K resolution, it would apply to users of all mobile platforms. EDIT: Looks like strudelz100 beat me to it.

There can never be enough truth speakers among this sea of fanbois. Kudos.

Yes but the display on the Note 4 is closer to 4k vs the iPhone so it the lose if far less.

A total waste of time talking about it if it doesn't work on there devices. Yes the chip can handle it but the device cant

It's not a total waste of time , maybe it's a hints to what apple has in store for us in the future?

lol too bad the iPhone 6 display is only 720p

Does the A8x on the iPad air 2 support 4k playback? That would be much more useful than the tiny low resolution iPhone screens.

19. strudelz100

Yes it would easily support 4K as well. But it would still be rendered at device resolution like EVERY OTHER DEVICE.
