With the rise of big-screen home entertainment, a smart home projector is increasingly showing its value.
Think of the scenes that make you excited:
These are the warmest images that remain in our memories, along with our busy lives. To start a fantastic experience at home, then how to pick a home projector that is right for you based on the size of the room will be crucial.
For a home projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W. A standard projector usually has a home projector ratio between 1.5 and 1.9. When the home projector ratio is less than 1, we typically call it a short throw lens, and when the home projector ratio is less than 0.6, we usually call it an ultra-short throw lens. As technology develops and people's needs change, the projection ratio of entertainment home projector continues to get smaller, projecting the big picture at short distances. For example, the Dangbei Projector F1, with a projection distance of only 9 inches, can achieve the effect of a 120-inch screen, let you in a home theater.
The following will describe how to calculate the home projector distance with the projection ratio. You can borrow this formula:
Home projector distance Feet= projection screen size (Inch) * projection ratio factor * *0.87*0.0254*3.280 .
For example, if the home projector ratio is 1.2:1, you need about 8.5 feet of projection distance to project a large 100-inch screen.
l Home Projector distance for optimal screen aspect ratio 4:3*1.09 = projection distance for screen aspect ratio 16:9.
l Home Projector distance for optimum screen aspect ratio 16:9*1.224 = projection distance for screen aspect ratio 4:3.
l Home Projector distance for optimum screen aspect ratio 16:10*1.027 = projection distance for screen aspect ratio 16:9.
l Home Projector distance for optimal screen aspect ratio 16:10*1.134 = projection distance for screen aspect ratio 4:3.
In the future, more projectors will be moved from the cinema to your bedroom and living room. Then the first thing to consider is the projection distance. If you live in a very small space then use an ultra-short focus projector that can project a large 100-inch screen in just 2 feet. If your apartment has a projection distance longer than 9 feet, then use a DangBei's home projector. DangBei's newest product delivers 1.2:1 projection ratio and HDR.10 technology, with a contrast ratio of 10,000:1. Only need 9 feet, you can enjoy the 120-inch large-screen viewing experience. The device is equipped with the Mstar 938 chip, compatible with 4K, running without jam.
