Hello a question to you and although it is about what the difference between Ultra HD and HDR is? Or is there none there? My question now refers to Netflix. Since I once own the Sky Receiver and once the Fire TV Stick. If I want to look over the Sky Receiver Netflix and find a series or movie what is on Ultra HD is yes at Netflix under the movie title in what quality it was shot and there's the Sky Receiver Ultra HD. But I take the Fire TV stick and do the same series on it is HDR. So my question is there a difference? If yes, which? And how do you actually recognize HDR?

Have HDR times in a series turned on because I find the picture somehow much darker.

Ultra HD (UHD) = 4k so 4 times full HD.

That's a good resolution for screens. The best standard right now.

HDR is not a resolution but a representation of color and Konstrastunterschieden in pictures / videos.

Say the picture looks livelier

HDR is when a picture is taken of several (for example, 5 pictures) with different exposures. (By laying on top of each other) this creates a nicer and deeper picture.

UHD or Ultra High Definition simply refers to a resolution of 4096 × 2160 pixels.

That the picture with HDR is darker than without HDR is due to the achieved depth.

There's no difference because it is 2 different things,

Ultra HD describes the resolution in this case 4k

HDR stands for a higher contrast (regardless of the resolution)

You've got photos of HDR now, in the context of 4K it's more about videos or TV. Since you do not make 5 recordings for HDR but takes the one and builds a screen that can more fully reflect the dynamics of the images.

So is that normal the HDR is darker? I've always wondered and thought that most of the television is not designed for it although my HDR can. So there's no difference. But the film or the series has 4k and HDR to it? And what can look more beautiful with HDR or without?

el

That's right, of course, should I have written about it.

That depends on the personal preference. I use HDR from time to time on my TV, but some movies make me too gloomy.

pu

HDR does not have to be darker, but the differences in brightness between the brightest punk on the screen and the darkest point on the screen can be greater than with non-HDR devices.

Ah okay now I understand. Because before I bought my tv last year I never saw it before hdr and then I switched on hdr and there the picture is so brownish and I thought it could not play that well (is a beginner model of sony) XF70)
