![]() ![]() This is assuming that the receiver is placed under the screen in an entertainment center. ![]() You must also find a way to provide power to the projector. If a projector is at the very back of the room, let’s say 15 feet away from the screen, then you will likely be running a 20-foot long HDMI cable from the projector to your A/V receiver. Less heat and sound disturbance from the projector.Closer positioning, therefore it is less likely to cast shadows on the screen.Here are some reasons why a short throw projector is more valuable than a standard throw projector: While a normal/long throw projector may need to be placed 10-15 feet away from the screen to produce the same sized image, the throw ratio determines whether a projector has a short, normal, or long throw. Depending on the throw ratio, a short throw projector could produce a 100″ image at 5 feet from the screen. Without getting too technical, a short throw projector can be much closer to the screen when compared to a normal throw projector. The main difference between a Short Throw and Normal Throw Projector. The filter or warped image is then output without any delay. The chipset basically applies a real-time digital filter to the video signal being input to the projector. Some manufacturers have still yet to perfect this type of technology. Now, the geometry correction applied to the image is quite complicated. In knowing this, you must be careful when mounting any short throw projector because the position should be exact. Some short throw projectors don’t allow for any adjustment of the lens at all. A high-quality lens is able to keep the image very clear, but this type of lens typically doesn’t allow you to adjust or zoom at all. How does a Short Throw Projector work?Ī short throw projector is able to produce such a large image while still being relatively close to the screen by using either 1) a high-quality lens or 2) a chipset that uses geometry correction to warp the image before it is projected through the lens.īoth of these things attribute to the slight price increase from a normal throw projector. This enables the everyday consumer to purchase and use this great technology in their homes. ![]() Yet, there is definitely a consumer market for short throw projectors, and the demand for them will continue to increase as the technology continues to improve! We also know that the costs for higher-end units will continue to decrease over time. It also helps save money on cable and installation costs. Because the projectors can be positioned much closer to the screen, teachers can walk in the front of the classroom without casting shadows on the screen. Sometimes they only hold a 10-15% premium to a normal throw projector.Ī good amount of the short throw projector market belongs to schools and educational centers. This has allowed for the prices of short throw projectors to become very reasonable. They used to be very expensive and rare, but projector technologies have greatly improved over time. The throw ratio is calculated using the distance from the projector to screen divided by the maximum projected width of the image. A short throw projector has a throw ratio between 0.4 and 1. A short throw projector is usually set or mounted very close to the screen (generally between 3 and 8 feet). ![]()
