Detecting Gamma Ramp Support

  • Article

If the device does not support gamma ramps in the swap chain's current presentation mode (full-screen or windowed), no error value is returned. Applications can check the D3DCAPS2_FULLSCREENGAMMA and D3DCAPS2_CANCALIBRATEGAMMA capability bits in the Caps2 member of the D3DCAPS8 type to determine the capabilities of the device and whether a calibrator is installed.
