The ASUS TUF Dash 15 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS TUF Dash 15 likely has higher resolution and brightness levels, making it suitable for general use and detail-oriented tasks like engineering and design. Its color accuracy, covering a wider color gamut, ensures engineers and designers see true-to-life colors, though its lower refresh rate may not be ideal for the smooth visuals critical in gaming and 3D. Conversely, the Lenovo IdeaPad Slim 3 offers adequate resolution and brightness for everyday tasks and acceptable color representation, but its screen fails to offer the high refresh rate desired by gamers and those working with 3D graphics.

How the ASUS TUF Dash 15 and the Lenovo IdeaPad Slim 3 compare to other laptops
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
