For general use, the screen quality of both laptops is fair due to their adequate resolution and brightness, making them suitable for everyday tasks like browsing and document editing.

Although they have very similar scores, PerfectRec considers Dell Inspiron 16 5635 to be very good for general use, while the Lenovo IdeaPad Slim 5i is good.

Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
