HDR (High Dynamic Range) explained

, or , is a new type of display technology that allows television pixels to display a wider range of colour and contrast combinations, providing a more realistic image and immersive viewing experience.

4K technology displays images at over eight million pixels (3,840 x 2,160), providing four times the detail of 1080p HD (2 million pixels in total). HDR technology enhances a pixel’s ability to become brighter or darker, expanding the set of colours that can be displayed. 4K ensures that the image is clear, while HDR uses colour ranges to create image depth. An HDR TV can cover a wider space within the colour spectrum. To quantify it, a standard dynamic range (SDR) television can display approximately 16 million colours, while an HDR-capable TV can display approximately 1 billion colours. This enables the creation of more realistic images on screen, and helps to mimic what a person might see in reality.

To watch 4K HDR on Optik TV, you will need the following:

With the Optik 4K Digital Box and a subscription to Internet 50 or higher, you’re ready for HDR as content becomes available. To deliver the best viewing experience, Internet 50 or higher is required to support the bandwidth requirements of 4K and 4K HDR video content.

To check if your TV is able to display HDR, check your owner’s manual or check the manufacturer's online support pages for your TV model to ensure that your settings are optimized for HDR. For example, on some Sony brand HDR-capable TV sets, HDMI port settings need to be changed from to in order for HDR content to be displayed properly.

Optik TV supports both HDR10 and HLG formats. To view content in HDR10 or HLG, your TV must support each individual format respectively. The most common format is HDR10; another format is Hybrid Log Gamma (HLG) used for live broadcast. Different manufacturers of television equipment (including digital boxes) and content producers use different formats of HDR, sometimes offering support for both.

Some 4K TV manufacturers models require you to download firmware upgrades to become HDR capable. Others require you to specifically update your TV settings so that the input you are using can support HDR.

In order to check if your TV needs further updating to settings or firmware:

In order to ensure you watch the best quality TV available to you, we permit the renting or purchase of HDR movies only if we can detect that your TV and any other a/v devices (e.g. receiver or amp) connected to our Optik equipment is HDR capable. If your equipment receives HDR information that your display is not capable of transmitting, you may notice colour distortion (e.g. too much green in the image).

For that reason, if we cannot confirm HDR capability, our service will automatically block the rental/purchase and direct you to find the HD version of that title.

When you have multiple TVs in your home, but only one is HDR capable, you may be able to rent/purchase a 4K HDR title on your 4K HDR TV, but when attempting to resume the title on your NON-HDR capable TV, playback will be in the highest video quality and resolution available to that TV (e.g. Standard Dynamic Range and HD).
