The ASUS Zenbook Pro 14 Duo has a better screen than the Dell Latitude 14 7490 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro 14 Duo offers excellent panel type, resolution, and brightness, providing sharp, vivid visuals that are ideal for general tasks and detailed engineering work, but its refresh rate isn't high enough to satisfy the smoothness desired in gaming or 3D applications. The Dell Latitude 14 7490, while having a decent panel that suffices for general use and engineering — with good color representation for precision work — falls short for gaming and 3D due to its lower refresh rate. Both laptops' screens lack the high refresh rates gamers need for fluid motion, though they provide suitable clarity and color for productivity and professional creative tasks.

"The Zenbook Pro 14 Duo OLED is a well-tuned instrument for content creators, excelling at a range of general office tasks as well as tasks that require a little more grunt like encoding and 3D rendering. The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."

"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."
