They tend to look flat by comparison, with white levels crushed and some layers virtually indistinguishable. There are several reasons for this. This means you miss out on the nuance that should be there. After all, your eyes can differentiate a lot more information than your TV feeds you. It dramatically reduces the amount of information transferred in order to match the technical limits imposed by your TV. Lately, though, TVs have become much more capable.
And by that, we mean bright. Of course, that sort of light would be blinding at maximum brightness. The idea is to let you see more of what is recorded. Sunlight will gleam properly off windows. Colours will be richer and more lifelike, with more delicate gradations and greater shifts in tone. Basically, your picture will look more natural and more real. It applies those specific standards to the picture displayed by the TV.
The key difference between Dolby Vision and HDR10 is that the former allows for dynamic metadata to be added on a frame-by-frame basis so that you're always getting the image as intended. It's adapted to the specific abilities of your TV, too, and auto-calibrates your TV to what it deems to be the best settings. In theory, this should allow for a subtler, more improved image. HDR10, meanwhile, applies its parameters scene-by-scene — for instance, every time a camera angle changes. While the quality of a Dolby Vision presentation is still dependent on how well it's implemented on each film — and we've seen one or two that have not been great — Dolby Vision done right is definitely better than the best HDR10, particularly in terms of subtlety and nuance.
The more recent extension of Dolby Vision is Dolby Vision IQ which adapts the picture's contrast and brightness according to the level of lighting in your viewing environment. The idea is essentially to make sure that the content doesn't come across too blown out or too gloomy and, in our experience, it tends to work very well. More recent releases include Godzilla vs. Kong, Joker and the remastered Indiana Jones Collection.
There are now lots of TVs that support Dolby Vision, too, although they do tend to be at the higher end of a manufacturer's range, likely due in part to the fact that there's a cost involved in licensing the technology and badge from Dolby.

Joining this race is HDR, the latest technology that's among the acronym-laden features on new TVs - and it's a tech that's growing.
That's continued through recent years, with HDR becoming more accessible across a full range of devices and services. HDR stands for high dynamic range. The abbreviation will be familiar because it's a term also used in photography, with HDR on some cameras and many smartphones: it's a feature on the iPhone , for example. It's the same thing, because on televisions, just as in photography, the aim is to recreate an image that's closer to that seen by the human eye, or to better recreate the vision of the original storyteller.
That often means balancing out light and dark areas or the range of colours, and not losing, for example, shadow detail because of a bright sky. When it comes to TVs, this is handled in a couple of areas. The first is contrast, dealing specifically with the relationship between light and dark, and colour, with HDR offering a wider range of colours, particularly in challenging situations like sunsets.
The results delivered by HDR should mean more sumptuous colours, bringing more realism and depth, and added "pop". HDR aims to be a visual treat, which it very much is. That results in fidelity in the darkness, as well as that very bright point of light, with both being rendered with lots of detail and colour. The "original storyteller" aspect is also important, as HDR is very much being pitched as bringing the director's vision to your TV, much like Hi-Res music claims to be bringing the artist to your ears.
In the case of HDR, this could extend beyond the realistic into more radically styled visuals. In previous standards, including those used on Blu-ray, it just wasn't possible to achieve the same results.
HDR uses panel technology deliver this wider colour range and contrast, and it's very much about brightness and illumination. To view HDR content, you need to have a display that's compatible with HDR, it's as simple as that - and for many that will be a television, although in recent years laptops, tablets and phones have all offered HDR too. HDR-capable sets are suped-up televisions. Many HDR sets have a backlight system that can output about 1, nits peak brightness or greater, whereas standard TVs typically only output nits, which is the level that Blu-ray and standard TV content is specified to.
Nits refers to the brightness, although this isn't used uniformly when watching HDR content - this only refers to brightness in particular places, those highlights in a scene. Using an increased brightness range and a wider colour gamut, HDR can recreate visuals that weren't previously possible. However this isn't about absolute brightness, it's about the range, so although you'll see some LCD manufacturers talking about nit brightness, others, like OLED manufacturers, might be offering nits.
Because both offer the wide range between dark and light, they both have that ability to carry the HDR label. HDR steps up to or bit Rec. In a word, the colors look more saturated. For example, in a sunset scene, you should see the bright light of the sun and the darker portions of the image with similar clarity, along with all the brightness levels in between. Check out the example below. The same is generally true of HDR.
By some measures, there is less content available in HDR than there is in 4K, but that's beginning to change. That includes home theater receivers , media streamers , Ultra HD Blu-ray players, and video projectors , as well as the original resolution of the content you're watching.
You'll also need a high-speed HDMI cable. Some 4K devices upscale lower resolutions to 4K, but the conversion isn't always smooth. This is referred to as peak brightness and is measured in nits. Content encoded in the Dolby Vision HDR format , for example, may provide a range of 4, nits between the blackest black and the whitest white. On the other hand, since the pixels in an OLED TV are individually lit, enabling the pixels to display absolute black, these TVs may have a higher perceived dynamic range even with lower peak brightness levels.
When a TV detects an HDR signal but can't emit enough light to display its full dynamic potential, it employs tone mapping to match the dynamic range of the HDR content with that of TV's light output.
And because most premium TVs have both standards, you don't need to focus on one standard over the other, especially if you're buying a TV that's larger than 55 inches. If you want a smaller TV than that, you may be happy with a p display, as you probably won't notice the difference in resolution. Actively scan device characteristics for identification.
