HDR TV or high dynamic range TV is the future of our tellies! HDR gives better contrast, greater brightness levels and a wider colour palette on your unit. Its main function is that it basically makes the images look more lifelike and real than traditional TVs.

It does this by preserving details in the darkest and brightest areas of a picture which our eyes can preserve much more easily as well as allows for more natural and true-to-life colours that are closer to how we see them in real life.


What makes an HDR TV

There are two aspects that define a HDR TV, these are their contrast performance and the number of colours they can display.

The level of contrast is a main factor that determines how good a TV picture looks. What contrast basically means is the difference between light and dark, and the greater the difference the greater the contrast. The peak brightness of a unit and the black level (both measured in nits) determines whether a TV can be considered a HDR TV.  A unit can only be considered as HDR if it can manage at least 1100 nits of brightness while at the same time pulling off dark scenes with only 0.05 nights of light emission.

The other important aspect is colour. The level of bit in a TV will determine how many colours the unit can produce. For instance generally appliances such as blu-rays use 8-bit colour which comprises of about 16 million different colours, while the new HDR TV can process 10-bit colour which roughly equates to over a billion different colours. This means they can produce a vastly expanded range of colour shades and reducing overtly obvious gradations between shades.

How do I know if a TV is HDR compatible

The best way is to look for the Ultra HD Premium logo. This means that the UHD alliance (a group made up of technology firms and content producers) have approved the technology of that unit. The UHD Premium label proves that the TV has met the minimum specifications needed to be truly HDR compatible.

Will everything I watch be in HDR?

Unfortunately no much like the IMAX screens we go to see in the movies, contact has to be specifically mastered for HDR in order to work. Thankfully through advancements in online streaming from sources such as Netflix and the creation of Ultra HD Blu-ray content creators will be able to deliver more HDR content more easily.

How do I start watching HDR content

There are only really two options at the moment to access HDR content. The first would be to buy a new Ultra HD Blu-ray player or to stream HDR videos from streaming sources such as Netflix. Most importantly though your TV must comply with the HDMI2.a standard or any TV with the Ultra HD Premium label.

It seems that HDR TV has much to offer in regards to home viewing and there is still so much improvement and enhancement going on in this new sector of technology, in our opinion it is certainly worth looking into this amazing new home tech!
