Everything You Need To Know | 4K Ultra HD HDR
As a start, we’ll explain things in a simple manner. First off, we will discuss what 4K means then followed by the meaning of Ultra HD then HDR.
What is 4K?
What is 4K? It’s one of the most common question asked by people who have seen a 4K TV for the first time. To be precise, 4K is the term used by professional video and cinema production referring to the number of horizontal pixels of a resolution of an image or display. In this case, that is 4096 x 2160 pixels. Commonly, you might have heard about the terms HD, SD, or Full HD. Basically, it’s the same thing. The only difference is the number of pixels or size of the resolution display. However, there is a misconception that Ultra HD ultimately means 4K. That’s incorrect.
What is Ultra HD?
What is Ultra HD? Ultra HD is a term that is closely tied to the term 4K. However, that is a common misconception. Basically, Ultra HD and 4K are two different things or refer to two different aspects. Ultra HD or Ultra High Definition is the term that refers to an image or display with a resolution of 3840 x 2160 pixels. If you’re familiar with the terms SD, VGA, HD, and Full HD, Ultra HD ultimately means the same thing but is only bigger than the latter.
In this section, we aim that enlighten everyone the main difference between the terms 4K and Ultra HD. These two terms are closely tied to each other as most 4K TV manufacturers names their products with both terms. For example, the LG C8 OLED 4K Ultra HD Smart TV. From that alone, everyone will get the impression that 4K and Ultra HD means the same thing.
In the table of resolution below, it compares and states the number of pixels that each term represent.

|Full HD||1920 x 1080||1080p|
|HD||1280 x 720||720p|
|VGA||640 x 480||480p|
So after reading the upper part, we hope that you, our readers, have come to an understanding that, although 4K and Ultra HD refers to the same thing, both terms still have a marginal difference that differentiates them against one another.
So moving onwards…
What is HDR?
The term HDR basically means High Dynamic Range. There are other meanings of this term but in this case, we are talking about TVs. So what really is HDR for TVs? What are those TVs that have HDR on it? Fast and simplest answer is — HDR is a technology and picture processing technique that provides better contrast, greater brightness levels, more details, and a wider colour palette. It is simply about making images displayed on a TV that features HDR look more realistic. To a level where what you actually see when you look at an object or place is close to what the TV produces. Something that aims to give picture quality close to human eye quality.
Ultimately, despite having the majority of the 4K TVs nowadays support HDR, it all depends upon the design and performance of the TV. To fully enjoy the rich experience that a true HDR TV provides, it should satisfy the following criteria:
- A screen capable of displaying over a billion rich colours.
- Capable of reproducing at least 90% of the DCI/P3 cinematic colour standard.
- Capable of achieving a sufficiently broad contrast ratio.
If you’re looking for a TV that’s capable of doing these things, then we highly recommed that you take a look at the LG 2018 C8 OLED 4K Ultra HD Smart TV.
