The HTC One M9's screen resolution is 1080x1920 pixels, 441 ppi pixel density.
The measurements used to determine a monitors screen resolution is Pixels per Inch (PPI). The size of a monitor in inches and the total pixels in the horizontal and vertical directions determines the PPI of the screens resolution. For Example a 15 inch monitor has a maximum of 1024x768 pixel resolution.
The difference between 72 ppi and 300 ppi in image resolution is the level of detail and clarity. 300 ppi provides a higher resolution and sharper image quality compared to 72 ppi. This means that images with 300 ppi will appear crisper and more detailed when printed or viewed on high-resolution screens.
PPI, or pixels per inch, is a measurement that indicates the pixel density of a screen, determining how many pixels are displayed in one inch of the screen. A higher PPI means more pixels are packed into each inch, resulting in sharper and more detailed images. PPI is essential for assessing display quality, especially in devices like smartphones, tablets, and monitors. To calculate PPI, you can use the formula: PPI = √(width² + height²) / diagonal size (in inches).
PPI stand for Pixels Per Inch and refers to resolution (number of pixels in a single inch) on a screen. DPI stands for Dots Per Inch and refers to resolution (number of ink droplets in a single inch) on a printed page. the two terms are often used interchangeable .
Images with a resolution of 300 ppi have more pixels per inch than images with a resolution of 72 ppi. This means that the higher resolution image will have more detail and sharpness, resulting in a higher quality image when printed. The lower resolution image may appear pixelated or blurry when printed at a larger size.
The Apple iPad's touch screen is 9.7-inch (diagonal) in size, with 1024-by-768-pixel resolution at 132 pixels per inch (ppi).
High resolution for a JPEG image is typically considered to be around 300 pixels per inch (ppi) or higher. This level of resolution ensures that the image is sharp and detailed when viewed on a screen or printed.
The maximum size at which you can print a photo depends on the resolution of the image. Higher resolution images can be printed at larger sizes without losing quality, while lower resolution images may appear pixelated when printed at larger sizes. It is recommended to use images with a resolution of at least 300 pixels per inch (PPI) for high-quality prints.

Yes it is, depend of what You want to do with image. IF You want to print then resolution is very important, if You gonna post image on web site more important are pixel dimensions because on web images will be displayed with 72 ppi regardless of original image resolution.
