Calibrate Built-in Display for HDR Video in Windows 11

HDR content offers better brightness and color capabilities compared to traditional content (sometimes called standard dynamic range [SDR] content). Traditional content typically shows details in a bright part of a scene or a darker part of a scene but not in both parts at the same time. For example, if the shot focuses on a bright window in the scene, details in the shadow are lost.

Whereas HDR can show a wider range of colors and light and more details in between the extremes. Colors are more vivid and unique in HDR content. Additionally, bright parts of a scene are brighter while dark parts can be darker, and you don’t lose any details.

You can calibrate your built-in HDR display to get the video quality and look you want when you’re watching streaming HDR video. By calibrating your display, you can set the balance between the details in the bright parts of a scene and the details in the dark parts of it. For example, the bright parts of a scene might include things like sunshine, fire, and light reflections. The dark parts of a scene could include shadows or dimly-lit rooms.

This tutorial will show you how to calibrate the built-in display for HDR video for your account in Windows 11.

Change HDR or SDR Content Brightness for HDR Display in Windows 11

HDR content offers better brightness and color capabilities compared to traditional content (sometimes called standard dynamic range [SDR] content). Traditional content typically shows details in a bright part of a scene or a darker part of a scene but not in both parts at the same time. For example, if the shot focuses on a bright window in the scene, details in the shadow are lost.

Whereas HDR can show a wider range of colors and light and more details in between the extremes. Colors are more vivid and unique in HDR content. Additionally, bright parts of a scene are brighter while dark parts can be darker, and you don’t lose any details.

You might need to adjust the relative brightness of SDR and HDR content for your HDR-capable display. This is because a display interprets an HDR and SDR signal differently, and the results will vary by make and model.

When you change the SDR content brightness setting for an external HDR display or HDR content brightness setting for a built-in HDR display, the effect it has on SDR content depends on whether it’s an external or built-in HDR-capable display:

  • On an external HDR display, this setting will change the brightness of SDR content relative to HDR content.
  • On a built-in HDR display, the brightness of SDR content is controlled by a separate brightness setting, or it might be controlled automatically. Since the brightness of SDR content is already set, the HDR content brightness setting will change the brightness of HDR content relative to the brightness of SDR content.

For built-in HDR displays, such as on HDR-capable laptops, both the brightness setting and HDR content brightness setting will affect the appearance of HDR content.

  • Brightness setting. When viewing HDR content in a bright area, you might need to increase the brightness setting to see the display. However, this will reduce both the effective dynamic range for HDR content in apps and the overall contrast because the darker pixels will appear brighter. To improve the appearance of HDR content, view HDR content in a darker area and use a fairly low brightness setting. If the brightness is set to a very low level, that will increase the overall contrast between the brightest and darkest parts of the content. However, there will be less details in the darker parts of the content. For example, if you have a scene in a movie that shows a dimly lit room at night, you might see less details in that scene.
  • SDR content brightness or HDR content brightness setting. For most times, using the default SDR or HDR content brightness setting or one close to it should work well. You could set the SDR or HDR content brightness setting higher to help improve the overall contrast between the brightest and darkest parts of the content. However, this would reduce the details in the darker parts of the content, such as a scene in a dark room at night.

This tutorial will show you how to adjust the SDR content brightness or HDR content brightness for your account in Windows 11.

Find Windows Display Driver Model (WDDM) Version in Windows 11

The Windows Display Driver Model (WDDM) is the graphics display driver architecture introduced in Windows Vista (WDDM v1.0). WDDM is required starting with Windows 8 (WDDM v1.2). The WDDM design guide discusses WDDM requirements, specifications, and behavior for WDDM drivers.

WDDM provides the functionality required to render the desktop and applications using Desktop Window Manager, a compositing window manager running on top of Direct3D. It also supports new DXGI interfaces required for basic device management and creation. The WDDM specification requires at least Direct3D 9-capable video card and the display driver must implement the device driver interfaces for the Direct3D 9Ex runtime in order to run legacy Direct3D applications; it may optionally implement runtime interfaces for Direct3D 10 and higher.

This tutorial will show you how to find the current Windows Display Driver Model (WDDM) version you have in Windows 10 and Windows 11.

Connect to Wireless Display with Miracast in Windows 11

Miracast is a wireless technology your PC, laptop, or tablet can use to project your screen to wireless TVs, projectors, and streaming media players that also support Miracast. You can use this to share what you’re doing on your PC, present a slide show, or even play your favorite game on a larger screen.

You will see a control banner at the top of your screen when you are connected to a wireless display. The banner keeps you informed of the state of your connection, allows you to quick disconnect or reconnect to the same sink and allows you to tune the connection based on what you are doing. This tuning is done via the settings gear, which optimizes the screen to screen latency based on one of the three scenarios:

  • Gaming minimizes the screen to screen latency to make gaming over a wireless connection possible.
  • Watching videos mode increases the screen to screen latency to ensure the video on the big screen plays back smoothly and without glitching.
  • Working modes strikes a good balance between game mode and video mode where the screen to screen latency is responsive enough that typing feels natural, while ensuring videos don’t glitch too often.

By default, all connections start off in working mode.

This tutorial will show you how to wirelessly connect your Windows 11 PC to a TV, projector, another PC, or other kind of external display that supports Miracast.

Turn On or Off Content Adaptive Brightness Control in Windows 11

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions.

Some Windows 11 PCs can automatically adjust the screen brightness and contrast based on content that’s displayed on your built-in screen. For example, if you’re watching a video that has a dark scene, followed by a brighter scene (for example, one that shows a bright sunny day), the brightness and contrast may change. This is normal.

Content adaptive brightness control (CABC) provides ideal brightness and contrast levels, while saving power and providing longer battery life at the same time. If these sudden brightness changes are distracting, or if you work in photo and video apps where color accuracy is important to you, you can turn this off any time.
