In recent years, there has been a remarkable growth in display technologies that have revolutionized our viewing experience. High Dynamic Range (HDR) technology has come up as a major player in this domain. Its promising enhanced color reproduction, improved contrast, and more immersive viewing experience has taken HDR TV to a new level. Today, as we delve into the world of HDR, it is crucial to read its key features and how it compares to Standard Dynamic Range (SDR). Thus, this article will explore the essentials of HDR technology and discover what you need to know about SDR vs. HDR.
So, read on as in the following parts, we shall see SDR vs. HDR, which is better, their definition, and their advantages in daily life.
Before an HDR vs. SDR comparison, it is crucial to learn what they are. So, in the first part of this article, we will detail SDR HDR meaning along with their types.
SDR, or Standard Dynamic Range, is an old display technology that has been in use for many years. It represents a standard range of brightness and colors reproducible on display. SDR is characterized by a limited contrast ratio and a narrower color gamut, resulting in a more modest visual experience than HDR.
There are two different types of SDR that you can use in various applications:
This refers to the SDR standard used in traditional television broadcasting. It typically supports a color space known as Rec. 709, with a limited range of colors and brightness.
SDR displays are standard in computer monitors, smartphones, and older television sets. These displays adhere to SDR broadcast's limited color space and often calibrate to provide consistent color reproduction.
HDR, or High Dynamic Range, is a newer display technology that aims to overcome the limitations of SDR. It enables a more extensive range of brightness levels, a wider color gamut, and greater contrast ratios. HDR enhances the overall visual experience by delivering more vivid and lifelike images with improved details in bright and dark areas.
Four main kinds of HDR are currently being used or developed:
HDR10 is the most widely adopted HDR format. It uses a 10-bit color depth, allowing for a peak brightness of 1,000 nits or higher. HDR10 is an open standard compatible with most HDR-capable displays and content providers.
Dolby Vision is a proprietary HDR format developed by Dolby Laboratories. It supports a higher dynamic range than HDR10, with a peak brightness of up to 10,000 nits. Dolby Vision also utilizes dynamic metadata, enabling scene-by-scene or even frame-by-frame adjustments for optimal image quality.
HLG is a backward-compatible HDR format developed by the BBC and NHK. It allows HDR content to be broadcasted alongside SDR content, enabling a smooth transition between the two for viewers with HDR and SDR-compatible devices.
This HDR format aims to provide enhanced color accuracy and fidelity. It utilizes a wide color gamut and advanced tone mapping techniques to deliver a visually stunning experience.
Please note that the choice of HDR format depends on the content creators, display manufacturers, and the specific requirements of the application or industry.

To understand which is better, HDR or SDR, it is advisable to understand the similarities and differences between these two resolutions.
Despite their basic differences, SDR and HDR share similar basic display functionalities that include:
Now, let's explore the difference between HDR and non-HDR regarding quality, brightness, color gamut & volume, gradient, color depth, and internet speed requirements.
|Quality||Limited contrast and color reproduction||Enhanced contrast and color reproduction|
|Brightness||Standard range of brightness levels||Expanded range of brightness levels|
|Color Gamut & Volume||Narrower color gamut||Wider color gamut|
|Gradient||Limited ability to display subtle gradients||Improved gradient handling|
|Color Depth||8-bit color depth||10-bit or higher color depth|
|Internet Speed Requirement||Lower bandwidth requirements||Higher bandwidth requirements|
Thus, these differences result in a more visually immersive and lifelike experience with HDR, making it a sought-after technology for those seeking enhanced display capabilities.
No, the statement SDR is better than HDR is false since HDR offers several significant advantages over SDR. Thus, making it a preferred choice for many applications.
The above advantages make HDR the preferred choice for display quality and immersion.
To change from SDR (Standard Dynamic Range) to HDR (High Dynamic Range), you need the following:
Dolby Vision is currently considered one of the highest-quality HDR formats. It offers a comprehensive dynamic range and supports a peak glow of up to 10,000 nits, resulting in exceptional visual quality and precise color reproduction. However, the perception of quality can also depend on other factors, such as the content itself, the display device, and the viewing environment.
If all these four factors align, then your setup should be able to display HDR content and provide an enhanced visual experience:
Thus, that was about SDR vs. HDR. We detailed SDR HDR meaning, their differences, types, and similarities. Besides, we listed the benefits of using HDR as it is the best technology of our time. Lastly, we also answered some common questions related to checking if your system supports HDR, what is its highest quality, and how to switch from SDR to HDR easily.
