The Lenovo IdeaPad Slim 7i has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, and engineering and design.
The Dell Inspiron's screen may not display colors as vibrantly or accurately as needed for engineering and design, reducing its suitability for professional color work, and its lower refresh rate could hinder the smoothness desired in gaming and 3D applications. Conversely, the Lenovo IdeaPad Slim 7i provides a higher-quality display with more accurate colors and better brightness, making it a better fit for both general use and tasks that demand color precision, despite lacking a high refresh rate for optimal gaming and 3D performance. Both laptops, having screens not designed for high-refresh-rate activities, are less ideal for gaming or 3D work where fluid motion is key.

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
