Each output has a list of supported display modes (DXGI_MODE_DESC) for a given pixel format. For each output(IDXGIOutput), show the width, height, and refresh rate of each display mode the output supports for theDXGI_FORMAT_R8G8B8A8_UNORM format using theIDXGIOutput::GetDisplayModeList method.Example output for Exercises 2, 3, 4, and 5 is listed below. It is useful to use the OutputDebugString function for quick output to the VC++ output window.
