Is It Real 4K? is a Chrome extension designed to help users determine whether a UHD Blu-ray movie is truly 4K or if it has been upscaled from a lower resolution. With the increasing number of UHD Blu-ray titles available, it can be challenging to identify which movies use a 4K digital intermediate (DI) and which ones are "fake 4K" upscaled from 2K.

This extension simplifies the process by allowing users to right-click on an IMDB link or select an IMDB ID (tt1234567) and click on the "Is it real 4K" option. The extension then searches IMDB for the movie's technical information and provides a notification with the results.

By utilizing Is It Real 4K?, users can easily verify the authenticity of UHD Blu-ray movies and make informed decisions about their movie-watching experiences.
