I haven't used it much. Here are some reference images with a Fire TV Stick 4K MAX 1st generation connected. The screen size is approximately 70 inches. I took the photos from a distance of about 1.5 meters. I tried to make them look as close to the actual view as possible, but the colors are a bit richer and the resolution appears higher, so please use them as a reference only. I may have overlooked something, so please ask any questions you have before purchasing. Thank you. Please refer to the manufacturer's website or YouTube for detailed specifications.
