With the rise of big-screen home entertainment, smart projection is increasingly showing its value.
Think of the scenes that make you excited:
l Family and friends get together for a cinema-like viewing moment
l A birthday party filled with Popcorn and googling of kids
l Cheering and shouting for Sporting events or immersive large-game
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 projector that is right for you based on the size of the room will be crucial.
For a 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 projection ratio between 1.5 and 1.9. When the projection ratio is less than 1, we typically call it a short throw lens, and when the projection 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 home entertainment projectors 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 projection distance with the projection ratio. You can borrow this formula:
projection distance Feet= projection screen size (Inch) * projection ratio factor * *0.87*0.0254*3.280 .
For example, if the projection ratio is 1.2:1, you need about 8.5 feet of projection distance to project a large 100-inch screen.
l Projection distance for optimal screen aspect ratio 4:3*1.09 = projection distance for screen aspect ratio 16:9.
l Projection distance for optimum screen aspect ratio 16:9*1.224 = projection distance for screen aspect ratio 4:3.
l Projection distance for optimum screen aspect ratio 16:10*1.027 = projection distance for screen aspect ratio 16:9.
l Projection 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. Let you and your family not only enjoy Netflix and other streaming media but also can be paired with the Switch and PS4 to immerse yourself in the first vision.
