This is a home projector. There are black marks on the screen, but you can still see the image without any problems, so I am selling it at a bargain price. Please consider purchasing if you don't mind the above. A Fire Stick is required separately to watch Netflix and Prime Video. The M1 projector features the latest dual-band 2.4G or 5G WiFi connection. With its strong anti-interference capabilities, it achieves a stable signal and high transmission speed. The home projector can wirelessly play audio via 5.2 Bluetooth, providing a home theater experience. The 4K projector is equipped with a native resolution of Full HD 1920x1080P and a high brightness of 12000lm, supporting 4K and reproducing colors faithful to the original image without high-quality compression. The home projector supports a wide range of screen projection sizes, with a maximum projection distance of 300 inches.
