What is PPI in computer monitor?

Delving into the world of computer monitors, one term often crops up: PPI, or Pixels Per Inch.

Many users ask what exactly PPI signifies and how it impacts their computing experience. In this article, we will explore the meaning and implications of PPI for image quality, eye health, and the overall viewing experience.

How Many PPI is Good for a Monitor?

Generally, present-day monitors boast varying PPIs based on their resolution. For instance, monitors with Full HD resolution have about 90 PPI, whereas 4K monitors possess roughly 163 PPI.

Similarly, televisions exhibit varied PPI, with Full HD TVs sporting approximately 40 PPI and 4K TVs displaying around 80 PPI. These PPI values, whether for monitors or televisions, significantly influence the visual quality.

Does Higher PPI Mean Better Quality?

Speaking of image quality, PPI plays a prominent role. Essentially, PPI indicates the number of pixels contained in each inch of an image.

Monitor tft LCD can produce greater pixel densities, entailing higher PPI, facilitating the display of a greater amount of pixel information, culminating in high-quality, crystal-clear visuals. Thus, a higher PPI often equates to improved image quality.

What is a Good PPI Screen?

Screens can be broadly categorized based on PPI into three primary types: standard, high, and very high pixel density screens. Standard pixel density screens typically range from 95 to 110 PPI.

Conversely, high-pixel-density screens feature a PPI count ranging between 110 and 140. Monitor arms successfully support these high pixel density screens that break the threshold and start at 140 PPI, providing an exceptionally detailed viewing experience.

Is Higher PPI Better for Eyes?

While higher PPI tends to offer better image quality, its impact isn't solely limited to visuals. It also affects the viewer's eye strain and fatigue level. High PPI displays require the eye muscles to perform more intensive processing to focus and track the image, potentially causing eye strain or fatigue over prolonged use.

Hence, when choosing a monitor with high PPI, consider adding a monitor riser to your workspace to balance the PPI and reduce potential strain on the eyes.


In conclusion, PPI is an intrinsic monitor parameter that significantly affects the image quality and user viewing experience. While a high PPI may result in superior image quality, it may also potentially lead to eye strain.

Therefore, when selecting a monitor, consider your usage and the appropriate PPI that will provide a balance between excellent visuals and comfortable viewing. For a deeper understanding of how to optimize your monitor settings for public health, you might find this monitor arm guide helpful
