When choosing between the Dell Inspiron 16 5620 and the Lenovo Flex 5 14, consider your specific needs. The Dell Inspiron offers a larger screen and better contrast but is less portable due to its size and weight. It's more affordable, making it suitable for general use and budget-conscious buyers. On the other hand, the Lenovo Flex 5 has a touchscreen and a more powerful processor, making it better for tasks that benefit from increased performance, such as engineering and 3D work. It also boasts longer battery life and higher portability thanks to its smaller size and lower weight, but it comes at a higher price. Both have similar RAM and display quality, but the Lenovo offers more storage out of the box. Give Feedback

The Dell Inspiron 16 5620 and the Lenovo Flex 5 14 have similar screen quality.
For general use, both the Dell Inspiron and Lenovo Flex 5 have displays that offer adequate resolution and brightness for daily tasks like browsing and video streaming, but they might lack the superior clarity and viewing angles of higher-end panel types. In engineering and design, professionals may find the color representation limited as these laptops may not cover the wider color gamuts necessary for precise color work. For gaming and 3D applications, their screens are less suited because they lack the high refresh rates essential for smooth motion, although their resolutions and panel types are serviceable for casual gameplay and basic 3D work.

"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)."

"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
