How is HDR displayed in video games?

There are two main methods of HDR support in modern video games. The first method is built-in support, which provides the best image quality, allowing players to enjoy all the benefits of high dynamic brightness. The second method is automatic upgrading from SDR, which improves image quality without significantly increasing resource consumption. These technologies allow developers to optimize visual effects and create a more immersive gaming experience for users.

Many video games released before 2017 do not have native HDR support, which limits their ability to effectively display high dynamic range. For PC and mobile users interested in HDR-enabled games, we recommend checking out the full list of available games at [this link](https://www.hdreport.com). HDR support significantly improves visuals and allows players to enjoy more vibrant and realistic images.

One of the key innovations of the Xbox Series X/S console is the Auto HDR function, which automatically converts content from SDR to HDR. This technology is also available on PCs for many games using DirectX 11 and 12. To activate Auto HDR, users should go to the Windows HD Color settings, which will allow them to enjoy improved graphics and richer colors in games. Using Auto HDR significantly improves the visual quality of games, making the gaming process more immersive and realistic.

The game Gears 5 is a shining example of the successful implementation of HDR technology. The image below shows the difference between SDR (left), Auto HDR (middle), and the custom HDR (right) developed by The Coalition. This demo clearly illustrates how the built-in HDR displays significantly more colors and tones than the auto-updated version. This highlights the importance of using custom solutions to achieve the highest image quality and immersion in gameplay.

Colin Penty, Technical Art Director on Gears 5, emphasizes the importance of carefully calibrating content to achieve high-quality HDR. We paid special attention to the brightness of flashes and lighting in the game world to create a realistic atmosphere. Each level requires individual adjustments, as different locations have unique lighting requirements. This allows players to immerse themselves in the game and get the most out of the visual experience.

We spent significant time calibrating the display, taking into account various lighting scenarios. As a result, we implemented the ability to hide the calibration image and added controls, including maximum brightness and HDR contrast. This allows gamers to customize the image to their preferences, providing an optimal viewing and gaming experience.

Despite advances in HDR technology, there is still a lack of games on the market that can offer high dynamic range on the level of Gears 5. Many developers have not yet mastered this technology, which limits the choice of users who want to enjoy high-quality graphics and realistic colors. Games with high dynamic range are becoming increasingly popular, but their number is still not enough to satisfy the growing interest of gamers for visual effects and an improved gaming experience.

An Overview of the Different Types of HDR: What You Need to Know?

High dynamic range (HDR) is an important technology in modern video production that significantly improves image quality. HDR standards are developed by VESA (Video Electronics Standards Association), which was founded in 1989 by nine leading graphics card manufacturers. This technology enables the display of a wider range of colors and contrast, providing viewers with a more realistic and immersive visual experience. The introduction of HDR into various devices, including TVs, monitors, and projectors, opens up new possibilities for content creators and users, improving the overall viewing experience and creating a more immersive visual experience.

DisplayHDR is one of the most popular standards defining HDR characteristics based on brightness, contrast, and color gamut testing. To evaluate your monitor's HDR capabilities, there are specialized tests that can help you verify its effectiveness and compliance with standards. These tests reveal how well your monitor handles bright and dark scenes, as well as how accurately it reproduces a wide range of colors.

A key indicator of HDR quality is peak luminance, measured in nits (candelas per square meter). A higher peak luminance value allows for better differentiation between light and dark areas of the image. In HDR, peak luminance can reach 400 nits, which is 50% higher than most SDR displays, which range from 100 to 350 nits. This significant difference provides deeper contrast and improves overall visuals, making HDR technology the preferred choice for movie and gaming enthusiasts.

DisplayHDR 400 is the entry-level HDR standard and offers 8-bit image quality. In contrast, more advanced standards such as DisplayHDR 1000 and higher utilize 10-bit processing, providing a wider and more saturated color range. This allows for greater detail in both highlights and shadows, which is especially important for professional graphics and video production. The choice between different DisplayHDR levels depends on user needs and usage conditions.

LCD displays do not emit light on their own. Instead, they rely on the backlight passing through the screen to improve black levels thanks to local dimming technology. True Black adjusts the backlight at the pixel level to achieve rich, deep blacks. This technology significantly improves contrast and makes images more realistic, which is especially important for watching movies and gaming.

True Black stands out due to its high frame rate, providing a rapid transition from black to maximum brightness in just two frames. This makes it one of the most advanced HDR standards, delivering high image quality and deep contrasts.

All versions of DisplayHDR are based on the HDR10 standard, which is open and widely adopted by modern displays without the need for additional royalties for manufacturers. This makes HDR10 an accessible and attractive choice for creating high-quality content and improving the visual experience of users.

VESA recently denied rumors about the development of a new DisplayHDR 2000 standard. Despite statements from companies such as Samsung and Acer, the organization confirmed that this standard does not currently exist. This retraction highlights the importance of accurate information in display technology and confirms that current HDR standards continue to evolve, but the new DisplayHDR 2000 level has not yet been implemented.

Many display manufacturers, in addition to VESA, are creating their own HDR standards. One such standard is Dolby Vision HDR from Dolby, which supports color depths of up to 12 bits. This technology delivers 40 times brighter highlights and 10 times deeper blacks than traditional standards. Dolby Vision HDR is already implemented in popular games such as DIRT 5 and Call of Duty: Warzone, allowing players to enjoy richer and more realistic graphics.

Dolby Vision is a closed standard, requiring hardware certification for its use. This increases the cost of displays that support this technology. In 2021, Microsoft plans to introduce Dolby Vision support on PCs and next-generation Xbox consoles, opening up new opportunities for gamers and users who want to enjoy high-quality images.AMD's FreeSync HDR technology synchronizes the display's refresh rate with the graphics card's frame rate, significantly reducing latency and improving gameplay smoothness. FreeSync HDR is supported in popular games like Call of Duty: Black Ops 4 and Borderlands 3, allowing players to enjoy higher-quality graphics and responsive controls. Activation of this technology requires a FreeSync HDR-certified monitor and a compatible graphics card. Using FreeSync HDR makes the gaming experience more immersive and comfortable.

The Impact of HDR on Gaming Performance: What You Need to Know?

Using HDR (high dynamic range) in video games has a significant impact on system performance. Research conducted on AMD and NVIDIA graphics cards shows that activating HDR often leads to a decrease in frame rate (FPS). Specifically, Star Wars: Battlefront 2 records a small decrease of 0.4 FPS on AMD cards, while in Destiny 2 the drop can reach 12 frames on NVIDIA cards. This highlights the importance of choosing optimal graphics settings to achieve a balance between image quality and performance. Players should be aware of the potential performance loss when enabling HDR, especially in demanding games.

Enabling HDR can lead not only to a decrease in FPS, but also to an increase in input lag, which is especially important for eSports disciplines. It's important to note that many TVs don't support both Game Mode and HDR. This creates a dilemma for gamers, forcing them to choose between image quality and high performance. Therefore, it's important to carefully evaluate the impact of HDR on gaming to achieve the optimal balance between visual effects and control responsiveness.
