A designer is creating a webpage. Which graphic resolution is optimal for screen display?

The optimal graphic resolution for screen display is 72 pixels per inch (ppi). This resolution is standard for digital images as it was developed based on the typical resolution of screens at the time it was established. At 72 ppi, images are rendered clearly on monitors while keeping file sizes manageable, which is crucial for web performance.

Higher resolutions, such as 300 ppi or 600 ppi, are designed for print media where detail and sharpness are critical. However, when used for screens, these high resolutions do not provide any additional benefit and can lead to unnecessarily large file sizes that slow down page loading times. While 150 ppi is an improvement over 72 ppi, it still does not align with common practices for web design, making 72 ppi the most appropriate choice for delivering sharp and quick-loading visuals on screens.
