Broad support for high dynamic range (HDR) video, such as HDR movies and TV shows from Apple or other providers, requires the latest version of macOS and a compatible Mac model. If your Mac, display, video cable, or adapter doesn't support HDR10, video plays in standard dynamic range (SDR).

Free Hdr Software For Mac
Apple Pro Display XDR supports several HDR formats, including HDR10, when used with a Mac compatible with this display.
Getting the best HDR picture
If HDR video doesn't play in high dynamic range or with the quality you expect, try these solutions.
Check your Mac
- Install the latest Apple software updates for macOS Catalina or later. Some HDR features are available only with the latest macOS.
- Choose Apple menu > System Preferences, click Displays, then make sure that High Dynamic Range is selected. This setting appears only on third-party displays that support HDR10, not on built-in displays. If you don't want to use HDR, deselect this checkbox.
- Choose Apple menu > System Preferences, then click Battery or Energy Saver. If “Optimize video streaming while on battery” is selected, your Mac saves energy by playing HDR video in SDR while on battery power. To play in HDR, connect your Mac to power or deselect this checkbox.
Check your external display
- Make sure that your display supports HDR10. If the display has its own HDR setting, turn it on or set it to prefer HDR when available.
- Make sure that your display is using the latest firmware from the manufacturer. Check your display's documentation for details.
- Some televisions support HDR only on a specific input, such as HDMI input 2 or HDMI input 3. Check its documentation for details.
Check your media
If you're playing premium content from a third-party content provider, check with the content provider to be sure that they support HDR on your Mac.
Check your cables and other devices
Best Free Hdr Software
- If you're using HDMI, make sure that the HDMI cable and adapter support HDR10. Apple recommends HDMI cables that have been tested with Apple TV 4K and a wide range of televisions, such as the Belkin UltraHD HDMI Cable. Compatible adapters include the Apple USB-C Digital AV Multiport Adapter and Belkin USB-C to HDMI Adapter.
- If your video connection passes through an AV receiver, sound bar, or other device before connecting to your display, make sure that the device supports HDR10 and is using the latest firmware from the manufacturer. You can test by connecting your Mac directly to the display.
Check your viewing environment
The brightness and color of HDR video may vary depending on your Mac model and the lighting in your environment. Lower lighting conditions, such as in a dim room, enhance the visual effect of HDR.

Hdr Program
After the compensation of alignment and ghost reduction, photos with different exposures will be merged into a digital HDR negative, which is also called a 32-bit float pointing radiance map in the HDR imaging workflow. Compared with conventional 8-bit image formats like JPEG or BMP, the 32-bit float pointing format has the capability to record a much wider range of values, and can thus accurately capture the full dynamic range of the real world. However, a 32-bit float pointing value cannot be displayed or printed on current 8-bit monitors or printers. Therefore, although a 32-bit float pointing radiance map records extremely accurate values, at this stage they are just meaningless numbers from the user's perspective because the results cannot be seen. 'Tone Mapping' is the technology used to convert a 32-bit float pointing format to 8-bit images for display or print. Since 32-bit float pointing radiance map is also referred to as the digital HDR negative, Tone Mapping can be regarded as a kind of photo development, but for digital photos.
