opencv可以设置全屏显示图片，具体代码如下，环境：win10 32bit, opencv249

cv::Mat img = cv::imread("d:/0.jpg");
	if (img.empty())
	{
		printf("img load error \n");
		system("pause");
		exit(-1);
	}

	cv::namedWindow("img", CV_WINDOW_NORMAL);
	cv::setWindowProperty("img", CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN);

	while (1)
	{
		cv::imshow("img", img);
		cv::waitKey(1);
	}
