Mine is a 20-inch LCD widescreen with a pixel of 1280*720, but it cannot play in full screen. As soon as it is full screen, there is a black block, but it can play in full screen when set to 1024*768. Every time I watch a movie, I have to set it, which is very inconvenient. Can you make a batch file? If it is 1024*768, click to become 1280*720. If it is 1280.*720, click to become 1024*768
