We recommend projecting them via an Amazon Fire TV Stick. ② To use more effectively, please watch the reference video for this product before connecting the Fire TV Stick to the projector. [Important Notes:] 1. To avoid screen tilt and abnormal noise, the projector must be placed on a level and stable table. 2. To maintain the projector's heat dissipation environment, please install the projector about 30 centimeters away from objects and walls. (Recommended distance between people and the machine is 1 meter or more) 3. It is also necessary to clean the dust filters of the air intake and exhaust ports in a timely manner. This helps the projector dissipate heat. It also has the effect of reducing fan noise. 4. Before use, make sure that the power adapter and connection cables (HDMI cable/AV cable/TV Stick power cable, etc.) are connected correctly.
