Some say that the optimal pixel density is somewhere are around 400 ppi, while others say that the pixel density detectable by the eye is closer to 1000 ppi.

For example, what is monitor resolution The answer is surprisingly simple once you look at it.

At its most basic, monitor resolution is how clearly a monitor can display visual content.

Monitor resolution describes the visual dimensions of any given display.

Expressed in terms of width and height, monitor resolution is comprised of a specific number of pixels.

This means that the screen will have a width of 1,920 pixels while the height of the screen will be 1,080 pixels.

This results in a grand total of 2,073,600 pixels on-screen.

This will, of course, depend on the resolution of the content you are viewing.

Additionally, more viewable content can fit onto a higher resolution computer screen than on a lower resolution screen.

Pixels are therefore the building blocks of any image you see on your screen.

Pixels and resolution are directly correlated and a higher resolution equals a higher number of pixels on a monitor screen.

Moreover, the more pixels a monitor has, the more detailed images can be.

For monitors and displays, DPI is scrapped in favor of PPI (pixels per inch).

While PPI is the correct term when referencing monitors and other displays, both terms are often used interchangeably.

A higher pixel density will mean that there are more pixels packed into every square inch of your screen.

This means that both have 1,920 horizontal pixels and 1,080 vertical pixels.

Now imagine that one screen is a 32-inch screen, while the other is a 25-inch screen.

Now you can see how pixel density comes into play because you will have the same number of pixels spread across a larger screen with the 32-inch monitor.

Thus, the smaller monitor will have a more densely packed pixel density, resulting in smoother lines and sharper images.

While, generally speaking, a higher pixel density is better, there is a point of diminishing returns.

As pixel density becomes higher and higher, the noticeable benefits of that higher pixel density become lower and lower.

This will eventually lead to a point where the benefits offered by a higher pixel density are undetectable by your eye.

To take things even further, it is common for smartphones nowadays to have pixel densities ranging from 300 ppi all the way up to over 500 ppi.
