If your projector is installed 30 feet away from the wall and your projector has a throw ratio of 1.5:1, your screen... If your projector is located 10 feet from the wall and your.
One of the most important things to cover when purchasing a projector is the lensing. Specifically, the throw ratio. This ratio tells us what size of image we can get from a certain distance away, and it can be calculated two different ways. D/W=T (distance divided by width equals throw) or TxW=D (throw multiplied by width equals distance) You probably won't need to find the throw ratio, as most manufacturers provide it in a semi-standard format, but here are a few calculations to give you an idea: Projector is 15 feet from the screen and fills an 8-foot wide screen, then the throw ratio equals 1.875:1 or 1.875 Projector is 10 feet. In film terminology, throw is the distance between a movie projector lens and its screen. It is the distance the image is thrown onto the screen, and it has a large effect on screen size. Home theatre installations may often have an incorrect throw distance in the room but this can be corrected by use of a short throw lens For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W. So for example, the most common projector throw ratio is 2.0. This means that for each foot of image width, the projector needs to be 2 feet away or D/W = 2/1 = 2.0
Therefore, you will need to consider the throw distance and the projector features that will give you placement flexibility. A projector's throw distance is the distance between the projector and the image on the screen (i.e., the distance that the image is thrown). A few common throw distances are Dann Corr of Barco Projectors gives an overview of throw ratio and projector placement. Present by Momentum Tech Tips

In many rooms, it can be difficult to properly project a reasonably-sized image with a standard throw projector
As much as possible, address the alignment issues when installing the projector before considering fixing the keystone effect with keystone correction or moving the lens of the projector instead of the projector or projection screen itself. The projector can only work with so many pixels. If you have to do lens shift, you want about 20 percent distance flexibility on the screen to minimize.

Results. Aspect Ratio (standard/widescreen) The standard proportion in width to height for a projector used to be 4:3, but modern projectors have a widescreen format of 16:9 or 16:10. Almost all new computers are designed in the widescreen 16:10 or 16:9 formats so if the budget allows we normally recommend getting a 16:9 or 16:10 projector (which means a WXGA or WUXGA resolution). Back To Top. For example, a standard projector might have a 1.5:1 throw ratio. So, to get a 60-inch image; the projector would have to be 7.5 feet back from the screen. Or, approximately 1.5 back for every 1 of screen. Any projector will have this ratio listed in the general specifications. Currently there are four categories of throw ratio; standard, long, short, and ultra short throw. We will have.
The Versatile Short-Throw Projectors: Most projectors are of the long-throw variety, with throw distance referring to the amount of space between the projector lens and the projection screen or wall needed to showcase a clear projection of the right size, aspect ratio, and resolution. A short-throw or short throw projector allows you to have a smaller gap between the projection screen or wall. Throw distance and zoom ratios are subject to a +/- 3% tolerance. End users, please check with your dealer before making any final decisions. For projector's featuring Lens Shift, adjusting one axis will reduce the available percentage of the opposite axis.

This then varies the projection distance and angle for each projector, which would then require that each projector feature different throw ratios and lens shifting capabilities. Given that in this type of setup each projector is of the same model, as explained above, fulfilling this requirement is something which only optional lenses can do Contrast Ratio. Contrast ratio is essentially the reflection of light from an all white and black image.To better simplify this concept, all you need to really understand is that the most intense white in contrast to the darkest blacks will give you a much sharper picture; bringing out all faint colors and tiny details found throughout the image

Throw distance Ã· throw ratio = screen width. Suppose you want to mount the projector 16 feet away from the screen, and this projector has a throw ratio of 1.4:1-2.8:1. You can use the lower ratio (1.4:1) as an example; you can divide 16 ft by 1.4, which made your screen size of 11.43 ft. (137.16 in.). And given the highest throw ratio of 2.8:1. The easy answer is, well of course not! Manufacturers will always provide the highest specs they deem reasonable and believable. They do this all the time for soundbar wattage, speaker wattage, amplifier wattage, projector lumens, projector throw ratio, etc. The list goes on and on. Don't base any purchase purely based upon the specs provided A projector screen works by reflecting the light back from your projector to your audience's eyes. The brightness of the image reflected back off of the screen's surface is measured in units of gain, gauging the reflectivity of that surface. The gain number represents a ratio of light that is reflected back from a surface from a light source.
Many projectors today have a 0.5:1 throw ratio. This means that for a 10' wide image, the projector will need to be 5' away from the screen. To figure out where a projector needs to be, click on the Complete Specs tab on the main projector page (under the Recommended Accessories section). Scroll down to the Projection Lens section. Most short-throw projectors have a throw ratio of between 0.38 and 0.75, meaning that to get an image with a 70in diagonal you'd need to have the projector between 68cm and 1.33m away. However.

Projector Throw: How far the projector needs to be in order to fill the object it is projecting on to. In most cases, that will be a screen or set. It can be quite time consuming to try and position the projector in the right place so that it fits the screen perfectly, so here is a formula that can get you started. This formula works well if you are projecting onto a screen with a 16:9 aspect ratio So, the equation will be: (throw ratio) x (width size of your screen) = (expected projector distance) 0.48 x 104.59 = 50.2 inches. To get a 104.59-inch wide display output on a projector with a throw ratio of 0.48, the expected distance stands 50.2 inches (or ~4.2 feet) In order to explain throw ratio, we first need to know that the throw distance is the distance between your cutting area and where the lens of the projector will be. throw ratio = throw distance / width of the projected area. For example, a throw ratio of 2.0 means that if your lens is 2m away from your cutting table, the width of the projected area will be 1m. If you have a smaller throw ratio of 0.5, your lens only needs to be 0.5m away from the cutting table for the width of your. What is projector throw distance simulation? The throw distance and setup height will vary depending on the projector even when a screen of the same size is used. With this simulation, it is easy to calculate the distance from the screen and the height to which install the projector Throw Ratio. The projector manufacturer will publish a number in the technical specifications. This number is the width of the screen multiplied by the published ratio. As an example if the screen width is 3 metres wide and the throw ratio is 1,5, then the throw distance will be 4.5 metres
Throw ratio is the key spec for determining where a projector can be placed to create certain image sizes. The keep-it-simple guideline: The smaller the space, the shorter the projector throw you'll want You project onto the mirror which is at an angle facing the sandbox. The mirror projection doubles the distance so you can set the projector lower than 6 feet. We never actually tried this, but there are many others who have. Here is one video where the keystone settings on the projector are explained. $3 short throw projector lens mirro Cine movie projectors, which were developed in 1895 by two French brothers named Auguste and Louis LumiÃ¨re (1862-1952 and 1864-1948), work by front projection. The projector is positioned behind the audience and throws an image over their heads onto a screen in front of them. Televisions, which became popular a few decades later, work by back projection. You sit in front of the box and watch a pattern of light that's being created by a very sophisticate
You're likely to need a short throw projector, in any case, to focus the image onto your screen. Take a look at our article on projector throw ratios here. A small space will also give you issues with projector placement. You don't want to hit your projector with your swing and you also don't want your own shadow on the screen image. Check out our in-depth article on where to position. For home theater systems, we recommend that consumers choose a projector with appropriate brightness to show the clearest images with the best color performance and contrast ratio effect. The light processing components of a projector consist of the projection lamp, which determines the highest brightness output, and color wheel, which controls color performance A larger throw ratio corresponds to a more tightly focused optical system. Thereby, the first difference between long throw and ultra-short throw is about the distance from the projector to the screen. This difference is decided by the type of the lens on the projector. Generally, the lens for long throw is cheaper than the one for ultra-short throw, due to the quality of glass.
Throw ratio is the relationship between your projectors distance from your screen and the width of the image. Almost all projectors have a zoom feature to adjust the size of the image so the throw ratio will be shown as a range, e.g. 1.1-2:1. For this example, in order to calculate the screen size width you will get from a specific distance, you would divide that distance by 1.1 to find the. The throw ratio is the ratio of throw distance (the distance from projector to screen) to horizontal image width. For a projector with a throw ratio of 2, for every 1 foot of image width, the projector would need to be 2ft away from the screen What is the throw ratio on a projector? The throw distance is how much space you need between the projector and the screen (or wall) to display a certain size image. Standard or long-throw projectors require a minimum of 6 feet between the projector and screen to project images of 80 inches or more. Short-throw projectors, on the other hand, can project a 100-inch image at a distance of only 4 or 5 feet. Check your specific projector's manual for a chart that lists the distance. Throw ratio. The throw ratio tells you how wide the image will be when you place the projector at a certain distance from the screen. For example, a 1.8:1 ratio will produce a 5-foot wide image when you place the projector 9 feet from the screen (5 feet x 1.8). Calculating the throw ratio is especially important if you plan to permanently mount the projector. If you can't install the projector far enough away from the screen due to space limitations, you may need a short throw projector. A. *2: Throw Ratio - For video projectors this ratio is the throw distance divided by the width of the projected image. A fixed throw projector can only change the image size by moving the projector closer or farther from the screen. Video projectors with a zoom feature can adjust the image size by zooming in or out, while leaving the projector itself unmoved. (Source
