The ASUS ROG Zephyrus G15 has a better screen than the ASUS Vivobook 15X for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Zephyrus G15 has a high-resolution display with bright and clear visuals, making it excellent for general use and detail-oriented tasks like engineering and design; its wide color gamut ensures accurate color representation crucial for professional design work. However, its lower refresh rate makes it less suitable for gaming and 3D applications where smooth motion is key. On the other hand, the ASUS Vivobook 15X offers fair image quality due to its adequate resolution and brightness, but it may not provide the vibrant color accuracy required for high-level engineering and design, and its modest refresh rate can hinder the gaming and 3D experience.

How the ASUS ROG Zephyrus G15 and the ASUS Vivobook 15X compare to other laptops
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."
