TOP TEN REASONS TO UPGRADE TO 4K HDR!


The purpose of new technologies is to make the TV picture better. But the latest new technology — High  Dynamic Range (or HDR) — really represents a significant improvement over what can be seen when you switch on the television. That's because of what HDR does: it creates a more "real" looking picture by increasing the level of contrast between the brightest whites and the darkest blacks the TV can display. So what are the reasons for upgrading to a 4K HDR TV? Here's 10:

1) MORE PICTURE INFORMATION
Metadata is information about how the TV picture should look (additional information sent with the video signal). A HDR-equipped television can reach levels of brightness and colors that a non HDR TV can’t because it is receiving HDR metadata telling it such things as how bright a highlight should be or how certain colors being displayed should look. 

2) DISPLAY A WIDE COLOR GAMUT
HDR-equipped TVs can display colors with significantly more saturation than that of a conventional TV. This allows for content, which had previously been produced with a much smaller color gamut, to now be expanded for presenting a more natural looking picture.

3) INCREASED COLOR DEPTH
Color depth references the number of colors a TV can display within a color palette (example: the many shades on the skin of a banana or a person’s face). HDR increases this, which results in less “banding” of the image by providing a more detailed and smoother-looking color.

4) DYNAMIC RANGE
A HDR TV displaying HDR content has higher brightness capabilities. So you get a more lifelike picture because it can display both the highlights as well as the darker imaging without compromising on either. This means that detail as found in both light and dark areas are evident to the eye at the same time.

5) BRIGHTER IMAGE
A HDR-equipped TV can produce more light in certain areas of the image being displayed than that of a  non-HDR TV.  Increasing the brightness makes for a more visible image.
6) COLOR BITS TRANSMITTED
HDR isn’t limited to the HDTV standard of 24-bit color (8 for red, 8 for blue, 8 for green), because it can add in extra colors in between what is already there. By filling in the gaps, a better picture is provided.

7) HDR STREAMING CONTENT
HDR content is visually superior to that made without HDR in mind. It can only be seen correctly (and enjoyed) on a HDR-equipped TV.
8) HDR 4K BLU-RAY DISCS
A Ultra HD Blu-ray disc has both 4K and HDR built in and eliminates the worries of streaming, such as bandwidth bottlenecks. This requires a HDR-equipped 4K Blu-ray player, which are now available.



9) IMPROVED WI-FI CAPABILITIES
Because HDR content is basically tied to the 4K resolution being streamed, this requires the Wi-Fi capabilities of the HDR TV to work efficiently. This also means the Wi-Fi reception of non HDR content is received even better than was the case previously when HDR content wasn’t an issue. 

10) CUTTING-EDGE CONNECTIONS
HDR-equipped TVs have the latest inputs for connecting peripherals like 4K HDR Blu-ray players, Sound Bars, among others. The latest audio pass-through standards are also in play. All this means that no kind of converter boxes or other conversion devices will be needed.
