and a screen the image will also increase. If your projector has a zoom lens, the lens can be adjusted to change the size of the screen image without changing
the distance of the projector. Since each projector lens is different, an online projection calculator tool will help you calculate the size of an image
The screen size calculator can help you determine the screen dimensions. Have you ever wondered what the statement, the diagonal of the screen is equal to 40" means? How much space does it take up on the wall? What are its height and width? Here you can determine the monitor size or phone screen dimensions. If you"re curious enough, you can even determine how to measure a curved TV screen size!
If you want to find the ideal size of your TV or its distance from your eyes, check out this TV size calculator. Another useful tool is this great projector calculator, which can help in fulfilling your dreams about a home cinema.
Repeat the steps for iPhone 8 Plus, choosing a 16:9 aspect ratio and 5.5-inch diagonal. And what do you get? 4.8" for screen width, 2.7" height, and 12.93 in² screen size. So even though the first iPhone has a longer diagonal, the screen size is smaller than in iPhone 8 plus. (iPhone X also has the big cutout and the curved edges, but we are not taking them into account - even with that simplification, the screen area is smaller).
Our screen size calculator offers the possibility to estimate both a flat and curved screen size. As we"ve already learned how to proceed with a flat monitor, let"s see the differences for a curved one.
How do I measure a curved TV screen size, then? - you may ask. To evaluate the screen"s length, height, and area, we can follow the same equations as for a flat one:
Assuming the screen"s length is the arc length of a circle, we can find the base depth and width by using the following formulas which we use in the screen size calculator:
If you"re after the size of the screen"s diagonal, you can either measure it or use Pythagoras" theorem where a & b are the screen"s length and width.
The size of a 16:9 screen depends on how long the screen"s diagonal is, as 16:9 is merely the ratio of the screen"s width to its height. If you have the screens diagonal, you can multiply that measurement by 0.872 to get the screen"s width. You can also multiply the diagonal by 0.49 to get the screen"s height. Then, if you wish to find the screen area, multiply the width by the height.
Deciding how large a videowall should be is more than a matter of determining how many display devices are required to fill a space on a wall. The manner in which the videowall will be used, the types and quantity of information to be presented, and the size and shape of the room should be considered before selecting the quantity and type of display. A videowall in a public setting for digital signage will have far different physical requirements than a videowall in a command and control center.
What is the “best” shape or aspect ratio for a videowall? If the objective is to make the videowall as large as possible, then its shape will be driven by the layout of the room. A shallow, wide room with a low ceiling will likely necessitate a short, wide videowall. Other room characteristics may result in a videowall shape closer to a square. But room layout is not the only important factor when determining the height and width of a videowall. The size and aspect ratio of the source content and their intended arrangements on the videowall will also influence its shape and design.
When creating sample window layouts, it is also important to consider which sources should be shown at native resolution, those which may be downscaled or reduced in size, and content that should be upscaled or enlarged. Having an idea of scaling requirements for the source content will help you determine relative sizes for the source windows on the videowall. The nature of the source content will be a determinant of how legible it may be when scaled. High resolution imagery may be reasonably legible when downscaled. Content can often be displayed in small windows as “thumbnails” to save space while being adequately discernible, and then upscaled or enlarged upon user control for closer examination.
While videowall processors allow images or graphics to be reduced in size, text or symbols may not remain legible if downscaled, or even when shown at native resolution. In this case, upscaling may be necessary, possibly leading to use of larger window sizes that may require enlarging the videowall. This topic is covered in detail in Font Size and Legibility for Videowall Content.
Once you are confident that your sample window layouts meet end user expectations, you can be sure that you have a good idea of the overall shape for the videowall, determined by the layout of the room and the source content to be presented. You should also estimate the physical and pixel dimensions for the videowall. Additional considerations, including pixel density and individual display or projected image size, will help you finalize the actual dimensions and configuration of the videowall.
The resolution of a videowall can be defined by the total number of horizontal and vertical pixels in the display array. It can also be described by the pixel density, or the number of pixels per unit area. Pixel density is determined by the individual display unit, in terms of its native resolution as well as screen dimensions. Pixel density remains constant, regardless of the size or layout of the videowall.
LCD panels generally deliver more than sufficient pixel density for close viewing distances, including the largest models. Pixel density will likely be an important consideration when projecting large images.
The sidebar provides detailed information on calculating pixel density. At a close viewing distance of 10 feet (3 m), the pixel density would need to be at least 28 PPI, or pixels per inch, to avoid visible pixel structure. As points of comparison, a 50 inch (107 cm) 1080p LCD panel has a pixel density of 44 PPI, while a 70 inch (178 cm) WXGA projection cube has a pixel density of 22 PPI. If the end user demands that multiple high resolution sources be displayed pixel-for-pixel, then it may be necessary to increase the pixel density beyond the minimum. LCD panels generally deliver more than sufficient pixel density for close viewing distances, including the largest models at 70 inches. Pixel density will likely be an important consideration when projecting large images. Table 2-4lists some recommended minimum pixel densities at various viewing distances.
The minimum pixel density for a videowall, based on the viewing distance and the visual acuity limit of 1 arc minute, can easily be calculated.All that is needed is a tape measure and a scientific calculator, or a mobile device running a scientific calculator app.Ensure the calculator is set to degrees, rather than radians.
