![]() PPI or DPI is a description of a monitor screen’s pixel density. While PPI is the correct term when referencing monitors and other displays, both terms are often used interchangeably. For monitors and displays, DPI is scrapped in favor of PPI (pixels per inch). What Is DPI / PPI?ĭPI (dots per inch) indicates the number of dots found within a one-inch line of a scan or print. Moreover, the more pixels a monitor has, the more detailed images can be. To visualize this, we can think of pixels as puzzle pieces each one makes up a small piece of a bigger picture. Pixels and resolution are directly correlated and a higher resolution equals a higher number of pixels on a monitor screen. Pixels are therefore the building blocks of any image you see on your screen. Pixels, or picture elements, are the smallest physical points on a display, as well as the base components. Additionally, more viewable content can fit onto a higher resolution computer screen than on a lower resolution screen. This will, of course, depend on the resolution of the content you are viewing. The higher a monitor’s resolution is, the more detailed an image can be because a higher resolution monitor will be made up of more pixels than a lower resolution monitor. This results in a grand total of 2,073,600 pixels on-screen. This means that the screen will have a width of 1,920 pixels while the height of the screen will be 1,080 pixels. In the case of a monitor with an industry-standard Full HD 1080p resolution, this display has a resolution of 1920 x 1080. Expressed in terms of width and height, monitor resolution is comprised of a specific number of pixels. Monitor resolution describes the visual dimensions of any given display. In addition to a monitor’s panel type, screen size, refresh rate, etc., monitor resolution is usually one of the first specifications considered when shopping for a new monitor. Today we’ll be diving right in to give you all the info you need to know about monitor resolutions and aspect ratios so you can make the best decision when selecting the right monitor for you. ![]() If you’ve ever been shopping for a computer screen or TV you’ve undoubtedly come across one or both of these terms. Monitor resolution? Aspect ratio? What does it all mean!? Or you can compare some monitors for yourself here. With the helpful primer that follows, you’ll be able to get the monitor that best suits your needs. The higher the resolution, the clearer the display. At its most basic, monitor resolution is how clearly a monitor can display visual content. For example, what is monitor resolution? The answer is surprisingly simple once you look at it. If you visit our camera page, you can sort by resolution in X and Y resolutions to quickly ID cameras that meet your resolution needs.įor all your imaging needs, you can visit We can also help identify which sensor is best based on the imaging conditions.Finding the best monitor for you can be a struggle, especially when you’re new to the technical specs. This makes it easy to test various iterations. If you do not like math, you can download our resolution calculator here and just enter the data. This calculation method assumes optimum conditions. As a note, the number of pixels required depends on many aspects of lighting, optics and algorithms used for processing. The camera resolution can now be selected! In today’s world, we could select a VGA (640 x 480) camera for the application. We have now determined that we need a minimum resolution of 640 pixels in the x-axis to provide 4 pixels across our feature that is 0.25mm in diameter. Rs = Rf / Fp = 0.25mm / 4 pixels = 0.0625mm pixelįrom the spatial resolution (Rs) and the field of view (FOV), we can determine the image resolution (Ri) required (we have only calculated for the x-axis) using this calculation: Rf is the feature resolution (smallest feature that must be reliably resolved) in physical units (mm)įp is the number of desired pixels that will span a feature of minimum size.Ĭalculating the spatial resolution (Rs) needed: Ri is the image sensor resolution number of pixels in a row (X dimension) or column (Y dimension) Rs is the spatial resolution (maybe either X or Y)įOV is the field of view dimensions (mm) in either X or Y We can calculate the resolution required as follows:
