XDisplayHdrModeResult
Specifies the current state of HDR (high dynamic range) support on the attached display.
Syntax
enum class XDisplayHdrModeResult : uint32_t
{
Unknown = 0,
Enabled = 1,
Disabled = 2
}
Constants
| Constant | Description |
|---|---|
| Unknown | An error occurred, and the current state of HDR support is unknown. |
| Enabled | HDR mode is enabled. |
| Disabled | HDR mode is disabled. |
Remarks
The XDisplayTryEnableHdrMode function returns an XDisplayHdrModeResult enumeration value that indicates whether the function can enable HDR mode for the attached display. If XDisplayHdrModeResult::Enabled is returned, the function also provides an XDisplayHdrModeInfo structure that contains the minimum and maximum tone map luminance values for HDR mode.
The following example attempts to enable HDR mode for the attached display. If XDisplayHdrModeInfo::Enabled is returned, then HDR mode is enabled for the display and the game uses the luminance values from the returned XDisplayHdrModeInfo structure to initialize in HDR mode; otherwise, HDR mode is either unavailable or disabled, and the game initializes in SDR (standard dynamic range) mode.
void Game::InitializeHDRMode()
{
// Attempt to enable HDR mode, then initialize based on the
// result of the attempt.
XDisplayHdrModeInfo displayModeHdrInfo;
if (XDisplayHdrModeResult::Enabled == XDisplayTryEnableHdrMode(XDisplayHdrModePreference::PreferHdr, &displayModeHdrInfo))
{
// HDR mode is enabled for the attached display.
InitializeAsHDR(
displayModeHdrInfo.minToneMapLuminance,
displayModeHdrInfo.maxToneMapLuminance,
displayModeHdrInfo.maxFullFrameToneMapLuminance);
}
else
{
// Either HDR mode is disabled for the attached display, or the
// attached display does not support HDR.
InitializeAsSDR();
}
}
