HiDPI displays, also known as Retina displays by Apple, offer higher resolution by displaying more pixels, resulting in superior image quality. This translates to greater image accuracy, although images may appear smaller when viewed in software such as Photoshop. To address this, it is recommended to enlarge the image display to 200% (select Display > 200%).

When creating web pages, using HiDPI displays requires producing images at twice their final desired size and then halving them by specifying the width attribute in the HTML code. It is important to note that the min-device-pixel-ratio property, formerly used in media queries, has been removed from web standards. Similarly, the use of the srcset property is no longer recommended.

Currently, the best approach for serving images adapted to different screen resolutions remains the use of JavaScript combined with media queries. This method offers optimal flexibility to ensure that images are displayed correctly according to the resolution of the device being used.
