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 color 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 pictures with an ultra-high resolution that is roughly four times that of current HD (1,920 x 1,080 pixels). HDR technology enhances a pixel’s ability to become brighter or darker, expanding the set of colors that can be displayed. 4K ensures that the image is clear, while HDR uses color ranges to create image depth.

What content is available in HDR?

HDR is an emerging technology, and while some high-end televisions are equipped with HDR capabilities, content using this technology is not available yet.

Is HDR the same between different devices?

Not quite. Currently there are a few different display formats for HDR display (think VHS vs. Betamax or Blu-ray™ discs vs. HD DVDs.) The most common formats are HDR10 and Dolby Vision. Different manufacturers of television equipment (including digital boxes) and content producers use different formats of HDR, sometimes offering support for both. The more common format to be used is HDR10.

It’s also important to note that television HDR is not the same as the HDR function on your camera or smartphone. Photo HDR is combining images together that have been exposed in different ways to create a single image, while television HDR focuses on pixel functionality. The two happen to be named the same.

Am I ready for HDR already?

With the Optik 4K PVR, you’re ready for HDR10 once content becomes available. To check if your TV is able to display HDR10, check your owner’s manual or check the manufacturers online support pages for your TV.
