When it comes to mobile testing coverage, then the QA team needs to keep a host of things in mind, and one of them is the display of the device. In this regard, one needs to keep the screen size, resolution, and Pixel per inch (PPI) density in mind. Now,...
To find a monitor’s pixel density: Measure the screen’s diagonal size in inches Note the resolution (width × height in pixels) Use the formula: √(width² + height²) ÷ diagonal size For example, a 27-inch 1920 x 1080 monitor has a pixel density of about 82 PPI, while a 27...
For example, a 400 x 400-pixel image, has a physical size of 4 x 4 inches and has a resolution of 100 pixels per inch (ppi). To reduce the image's physical size by half without resampling, you set the physical size to 2 x 2 inches. Photoshop increases the resolution to 200 ppi....
It’s used to describe image resolution on a screen, rather than in print. DPI, meanwhile, refers to number of dots in every inch and is generally used for print purposes. PPI and DPI do however serve very similar purposes, indicating the overall resolution of an asset. This is also why...
We’ve all become accustomed to the PPI (Pixels Per Inch) count on our iPhone and iPad displays, but another metric that’s worth knowing is the DPI (Dots Per Inch) of your mouse. This will determine how quickly the cursor can travel across the screen and how small the hand movements ...
Quantity helps, but the size and depth of each pixel also determine quality. This is why you should consider all the specs of a camera and its sensor, not just the number of megapixels. After all, there’s a limit to the size you can print or view your image; beyond that, you’ll...
significant difference between these two rates can result in image artifacts appearing when the computer-generated image frames change while the screen completes one display cycle. The difference between the two rates will determine the size and scale of the screen tearing distortion and how long it...
Megapixels and screen resolution are commonly used terms in thephotography industry. Both terms determine how sharp and well-contrasted your image will appear on a monitor. What Are Megapixels? In the simplest form, a megapixel is one million pixels. Pixels are tiny squares that make up a st...
Installation starts but a frozen cursor, frozen screen, or an error message interrupts startup. Fix an interrupted installation of Acrobat 9 or Reader 9 (Windows only) Error 1402:Could not open key [key name] Error 1406:Could not write value folders to key [key name] ...
Allow us to throw in a bit of a curve ball here by reminding you that if you want to calculate the density of pixels on your screen, this is not the calculator you are looking for; try PPI calculator instead. Density formula Another way to calculate the weight to volume ratio of an ...
