Temporary mono is a feature where a stereo swap chain can be presented using only the content in the left buffer. To present using the left buffer as a mono buffer, an application calls the IDXGISwapChain1::Present1 method with the DXGI_PRESENT_STEREO_TEMPORARY_MONO flag. All windowed swap chains support temporary mono. However, full-screen swap chains optionally support temporary mono because not all hardware supports temporary mono on full-screen swap chains efficiently.
