4K TV upscaling?

[pit5000]

I recall reading somewhere (I can't remember where) that all modern 4K TV's will upscale 1080p content to 4K. Is this true, or will only the higher end TV's do it? What exactly would determine the quality of the upscaling, firmware/software or the hardware (processors)?

 

I like my content in 60fps but it's almost impossible to find that above 1080p. If I'm to get a 4K TV I want to know for sure that I'm getting UHD60p.

i don't know if all tv upscales but the scaling is done by the tv itself

Yes all 4K UHD TV's will have upscaling. But that upscaling will work in VERY different ways, depending on the model.

 

Some will simply stretch the image ("technically" upscaling), whereas others will use a digital processor chip to extrapolate the missing information. Don't expect the upscaling to work very well on lower end models.

 

You'll want to read reviews of any TV you consider, and see what the review says about the 1080p content upscaling quality levels.

 

As for your content, I mean it really depends on the source medium. A lot of content is recorded in 24p (Movies) or 30p (TV shows), so playing that content back at 60fps won't make it look any better (or in some cases, may even make it look worse - see playing 24p Blu-Rays on a 60Hz TV). If the content's FPS is divisible to a whole number by 60, then it will generally look fine. However, 60Hz TV's have to use a method called "3:2 Pulldown" when playing back 24p content - basically it repeats 3 frames in a row, then 2 frames in a row, then 3, then 2, etc.

 

LCD panels (that includes both CCFL and LED) that have a 120Hz panel allow seamless 24p playback (As 120 is divisible by 24).

 

Anyway, that's mostly a side-rant.

 

TL;DR, read a review of any TV you're considering.

i've read some reviews over the past year, nobody ever talks about upscaling. It's quite frustrating

Hmm well to be fair, depending on your content, it's usually another device feeding the media.

 

For example, Blu-Ray players. Getting a 1080p Blu-Ray player w/ HDMI 2.0 and 4K upscaling, for example. Those are still pretty expensive though.

 

Also, your computer will also upscale content, if you connect it to the TV.

 

But in either case, if the Blu-Ray or Computer is doing the upscaling, that means the TV itself will be connected at 4K resolution. As long as your TV supports HDMI 2.0 (Which basically any good current models will), then you're fine using an external playback device to perform the upscaling.

I have a Vizio 4k Tv and its upscales content, At Least is Says it does on the box lol I have been Watching My Standard Blu Rays on a PS4 and its looks fine also i Have it Hooked up to an Antenna for over-the-air channels and theres some Standard Definition shit on there and it still looks Fine and Vizio isnt the best so i would assume a Samsung Model or Equivalent Would Definitely So the Same if not better
