The Razer Blade 18 has a better screen than the Lenovo IdeaPad Slim 7i for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad Slim 7i offers a clear and vibrant display suitable for everyday tasks and engineering work due to its resolution and brightness, but for gaming and 3D applications, it falls short because it lacks a high refresh rate, which is crucial for smooth motion. On the other hand, the Razer Blade 18 excels in providing a sharp and bright display with excellent color representation that benefits both general users and professionals in engineering and design, but like the IdeaPad, it may not be ideal for gaming and 3D due to a lower refresh rate than what's typically desired in that space. Both laptops, while offering pleasing visuals for less demanding tasks, may not satisfy gamers or 3D developers who prioritize fluid, rapid motion enabled by high refresh rates.

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
