The Lenovo Legion Pro 7i has a better screen than the Dell Inspiron 14 5420 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 14 5420 offers a screen that is adequate for daily tasks and productivity, but its limited color gamut might not display colors as accurately as required for professional engineering and design work, while its lower refresh rate could hamper the immersive experience in gaming and 3D applications. On the other hand, the Lenovo Legion Pro 7i with its very good screen quality excels in both general use and professional applications due to better brightness, higher resolution, and broader color coverage, offering richer and more accurate visuals; however, despite its advantages, it still falls short for gaming and 3D due to a lower refresh rate, which is crucial for smooth motion rendering in fast-paced scenarios. Overall, both laptops are geared towards different use cases, with the Lenovo offering a superior visual experience for most tasks except for the high refresh needs of gaming and 3D content.
