UHD TV, 4k tv listing 1080p scaling as "Native"

[BloodBane]

TLDR:

Is it common for UHDTV (4k) to offer a "Native" 1080p scaling option so it can produce a 1080p image without the "softening" you get running a monitor outside of its native resolution.

Looking to purchase this vizio TV to use on my PC.

2 of the features that made me chose this one (out of lower cost 50 inch range) are the cost, and the low input lag tested at 16ms (low for a hdtv anyway, not as low as my 1ms rogswift)

One thing I noticed on the features page tho, is it says the 1080p scaling on this set is "Native"

Does that mean that a 1080p input will look the same as it would on a native 1080p input of the same size?



I ask because with another of my monitors, a 4k 28inch PC monitor, any resolution outside of the 4k native resolution appears blurry, as it is not its native resolution.

Do you think this TV might be able to do that?






I am only running a 980ti gpu, and am using this as secondary from my 27inch 1440p monitor. I just thought that even if my GPU cant push 4k in games, i could use non scaling center timings settings on my GPU and still have a near 40inch area in the middle of the screen running 1440p.

But if this TV will also nativily run 1080p, I find it would just be another "plus".

Well, 4k can scale FullHD pixel perfect as four 4k pixels are equal to one FullHD pixel.

Hi gdunkley I use a 43'' TCL UHD tv and it also has native 1080p. I play many different games
from the oldest to the newest and I never had the issue of blurriness in any resolution from 640x480 up to 3840x2160.
With a 980ti you'll be able to play a lot of games in 4k.
My R9 390X is weaker and even so I played RotTR in DX12 max settings, AA off in 4k with 30 fps lowest framerate.

I thought that too with my B286HK 28inch 4k monitor. Selecting 1080p Creates a soft picture typical of a lcd running outside of its native resolution.


TV will be delivered in a few days, i guess I will find out.

I hope I get the same results. Thanks for the reply

There is a slight catch to that though.

A pixel isn't a square. Every pixel on an LCD screen consists of multiple diodes wich only emit a single color. They are very, very small and lie very close together, wich is why we perceive them as a single "dot" of color.

So on a native 1080p screen a single pixel is a just a dot, or even odly shaped. arrangement of diodes differs with panels. But when you do a "native" upscale from 1080p on a 4K screen, you get 2x2 dots. Wich, at decent pixel-density, will look like small actual squares.

Depending on panel and your sensitivity this can have the effect of the image appearing too sharp. So a manufacturer may decide their panels are better off with a (softening) scaling algorithm, even for 1080p @ 4K.
