The Lenovo Slim Pro 9i has a better screen than the Lenovo Legion Pro 7i for general use, gaming and AI, and engineering and design.
The Lenovo Legion Pro 7i offers a balance with strong resolution and brightness suited for everyday tasks and engineering applications where clarity and color representation are crucial; however, its lower refresh rate affects the smoothness desired in gaming and 3D rendering. The Lenovo Slim Pro 9i stands out with superior screen quality for both general use and professional design work due to excellent resolution, brightness, and wide color gamuts, ensuring precise color accuracy and vivid imagery, but like the Legion, it falls short for gaming and 3D due to a refresh rate that doesn't cater to the fluid visuals these tasks demand. Meanwhile, gamers and 3D artists often prefer laptops with high refresh rate displays that sacrifice some resolution and color accuracy for smoother motion and gameplay.
