Anyone own a UHD TV?

epitome

I don't like the term "4K" because they are not 4K i.e. they do not have 4000 pixels or more in the horizontal.

But Anyway, does anyone here have a a UHD TV? The bigger the screen, the better.

I want to know if when receiving a DVD input signal.... do any of the TVs have the option of displaying the video in the original resolution standard definition?

If it did, this would result in there being a small picture in the centre of the screen using 640 x 480 pixels. The user could then be given the option of zooming up if desired x2, x4 or x6

On a 65inch TV this would be an SD picture measuring 29cm x 19cm.
which is about a sheet of A4

Just wondering is all....thanks

Yes I do 55" LG UHD OLED, it upscales to a full screen irrespective of input resolution. And anything less than HD looks poor.

That's a very odd feature and I've never heard of it

I recently saw some adverts for them on TV, they look fantastic!! I never new my current TV was capable of showing that level of detail, I think i'll keep it a bit longer............

I have never heard of any HD or UHD television being able to do this. People want to display things full screen so I suspect that you are in such a tiny minority with wanting this function that TV manufacturers don't even consider doing it.

The closest you'll get is to use PIP but on a UHD tv PIP will probably be 1920x1080. And I've never seen PIP in center of screen.

Can't every tv do it via aspect ratio options? 640 x 480 = 4:3? Am I missing something?

Also, at a push, should it not be possible via connecting to a laptop/pc?

A third option may possibly be an app for a file player/viewer.

4:3 will be upscaled but will still have black bars at the sides, and 1.85:1 will upscale and have black bars top and bottom.

I think perhaps you misunderstand how TV resolution works.

A 4K TV will display 3840 x 2160 pixels, or 2160p.
A DVD player will at best output 1920 x 1080 pixels, or 1080p (or i, another standard).

If then you really wanted to display the output from a DVD through your TV in it's maximum resolution without any upscaling from the TV you would be using approximately one quarter of your TV screen to display the image from the DVD player and hence three-quarters of your TV screen would be blank.
Why on earth would you wish to do that?
This is why no TV AFAIK gives the option to view in the original output definition.

As you suggest, a 640 x 480 pixel picture would therefore be even smaller on a 4K screen and yes, on a 65" screen displayed somewhere around the size of an A4 sheet.
If you were to "zoom up" and increase the size you will be upscaling, in effect again using multiple pixels from your display to display each pixel that your DVD player outputs.
It is (as you may imagine) much easier to upscale to the size of the screen than to have a variable upscaling feature.

Just as with most things in life, some 4K TV's are better at this upscaling than others.
My LG OLED is rather good at it, depending upon the quality of the source material of course because (as you may imagine) no amount of electronic wizardry will improve an already-poor source greatly.

Here are a few explainers of resolution if you're interested:

All flat panel technology scales the incoming image to it's native resolution, that's just the way it works.
