HDR (High Dynamic Range) explained

HDR (High Dynamic Range) pixel technology explained

HDR , or High Dynamic Range , 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.

What’s the difference between 4K and HDR?


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.

Am I ready for 4K HDR?


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

  • An Optik 4K PVR
  • An HDMI cable (2.0a/2.0b)
  • A TV that supports HDR
  • Content available in 4K HDR format

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 Standard to Enhanced in order for HDR content to be displayed properly.

What content is available in 4K HDR with OPTIK TV?


Currently, OPTIK TV provides customers access to 4K HDR content, including:

  1. On Demand
  2. Netflix accessed directly from your Optik STB on channel 500 (requires Netflix Premium Account)
  3. Live broadcast on channels offering 4K HDR content

Note: 4K and HDR are two distinct technologies and when combined they provide the best viewing experience available. There is still content in 4K only (without HDR).

How do I watch 4K HDR content On Demand?


To access 4K HDR content On Demand:

  1. Select the On Demand button your remote
  2. Access the Featured or Movies folder
  3. Scroll to the 4K folder and select View All to see all available titles

When you order 4K HDR content as rental content or Own on OPTIK, you can access the HD version at no additional cost if HD format is available and the content provider has been granted the viewing rights. This way, you can watch this content on a 4K HDR TV or standard HD TV.

How do I watch 4K HDR content on Netflix?


To access 4K HDR content through Netflix on Optik, you require a premium Netflix subscription (Ultra HD). To upgrade your Netflix subscription login at netflix.ca/changeplan.

HDR titles can be identified by an HDR badge located above the title synopsis. You can also search for HDR using the Search menu and all HDR titles will displayed.

Tune to channel 500 to launch Netflix on your OPTIK 4K digital box.

HDR availability is subject to your Netflix subscription plan, Internet service, device capabilities and content availability. Visit netflix.com/termsofuse.

What HDR formats does OPTIK TV support?


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.

How can I check if my 4K TV supports HDR?


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:

  • Refer to your owner’s manual
  • Visit your manufacturer’s web site and find information specific to your TV model
  • Search technology blogs for information on the correct TV model settings to optimize your TV for HDR

Why do I get a message saying “HDR TV not detected” when renting/purchasing On Demand content?


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).

Can I resume my 4K HDR movie on another TV that is not 4K HDR capable?


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. HD).
