Is 4K on a mobile device same as your typical 4K TVs/Screens?

needed to replace my iPhone 6 Plus so yesterday I received an 8 plus I ordered and it’s cool, but looking on video bit there’s a 4K mode which in this case has the 30fps As in the 7, but also 60fps, now every option but 60fps in 1080p and 4K looks sluggish as you’d expect, its 4K seem a tad bit smoother at 60fps over 1080, so there doesn’t seem to be much difference, however if I wanted to record in 4K, does my computer/screen need to be able to support proper 4K or because it’s mobile they should play in upscaling players software?
 
You can play 4K content on any screen, it just won't be "proper" 4K because your screen doesn't support it.

It will obviously look nowhere near as good as if you viewed it on a 4K screen, but it might look better than if the source file was recorded in 1080P. Maybe.
 
You can record in 4k @ 60fps on your new iPhone - note the display on iPhone 8 plus is 1080p so you won't be able playback at 4k on there.

You will need a 4k display if you want to view the footage it at it's native resolution.

As 3 minutes mentions, you don't need a 4k display, if you have 1080P of 1440P monitor the footage should be downscaled.
 
Found some stuff about no native playback on win 10 unless the device had hw support for hevc playback - not clear to me if the gt 610 has this.
So if you have issues playing back with Windows media player grab VLC ftom videolan, its a very good player and includes h265 software decode.
 
I've never thought too much about this as have a 4K TV that I display all my 4K recordings on (iphone 7 plus and GoPro 5). But if the iphone can display the 4K content on its lower res screen then it should be possible to do this on a non 4k monitor/tv with the right app/codecs installed.

I've been pretty happy with the 4k @ 30fps on iphone 7 and gopro. Certainly not found anything jerky and did a lot of filming on horseback racing through the desert in arizona that came out really good. My one annoyance with the iphone is how cumbersome it is to flick between 1080p and 4K i.e. have to go to general settings, camera etc. Why they have not built this into the cameras video menu I do not know.
 
4K video on a 1080p display will look much better than 1080p video as long as the bitrate is good enough. Just check YouTube hom much better 4K looks on your 1080p screen.
 
That’s for replies guys.

The only difference I’ve noticed when I’ve checked the modes out is motion blur and slow refresh rate when moving, I did some quick moving which wouldn’t actually be the norm, I normally only record what my kids do or if I’m sight seeing maybe, I don’t use video that often, just the with 6 plus there is no 4K option so before that phone/screen got damaged and had like a constant auto focus flicker for pictures and videos, I used to record in its native 1080p 60fps and now seeing how that bit smoother 4K is I’d rather use that.

I’m away for the holidays, so I can’t try it with my computer yet, however that gt 610 won’t be there for too long, I am still aiming for a 1030 depending how I end up going about things, so I’m not too worried if it wouldn’t be up to scratch, I usually use whatever media player win 10 has, vlc or kodi aswell, but downscaling is fine and I store pictures/videos on my computer rather than for editing etc, just obviously need to be able to watch them still.


So to conclude then, other than my 610 to likely lack features, I shouldn’t have problems if I record in 4K on my phone and watch it on computer?
