We would like to take some time to highlight the importance of HDR:

• HDR is the game changer which will make viewing far more enriching for consumers at homes and professionals at work.

• HDR’s effect is most prominent on LCD screens. OLED screens emulate some of the benefits of HDR technology but doing so via different means.

• HDR can be transmitted at a limited capacity using a lower colour bit depth via High Speed (10.2Gbps or lower) HDMI cables, as well as via some HDbaseT facilities. In each case the benefit will be very limited due to the 8bit and low 24/25/30Hz transmission.

• HDR combined with a 10bits, 50Hz or 60Hz broadcast is noted as being the most significant factor in improving the experience of viewers.

•  HDR technology enhances brightens and colours the large 3840x2160  images by turning the very sizable image in to a vibrant colourful and highly contrasted image that rival the quality of professional cinemas images.

• There is a number of HDR standards, it is too early to predict if one of standards will dominate the marketplace. However, HDR10 and Dolby Vision and Hybrid Log Gamma (HLG) should be very closely looked at. Dolby Vision is offering a significant advantage over other HDR implementations as it offers a native 12bit performance. All other HDR techniques rely on a maximum colour depth of 10bits.
   

The HDR10 and Dolby Vision that are available exclusively in flat panels do not guarantee a uniformal performance, the amount of light output measured out of flat screen will likely be on an upward trajectory in coming years. Current flat screens (2016) can generate brightness levels of 1,000 nits, but the Dolby Vision standard may in the future brighten displays with 10,000 nits.

HDR’s features and its overall effect on the quality of the image has been massively increased during 2015 and 2016. But the technology is still evolving and there are a mix of views on the overall effect of the technology and it’s incompatibilities.

Compatibility between source and sinks should be very carefully evaluated when data/audio/video links used in domestic and professional environments.

​

To fully benefit from the many advantages of HDR, installers and integrators will need to carefully evaluate the complete transmission path and each of its components. Nue Tec 18Gbps and 30Gbps models are already set to transmit the very demanding Dolby Vision HDR and generate a 12 bit and illuminate display with a 4:2:2 colour density.
