The ASUS ROG Strix Scar 15, with its vibrant colors and high resolution, makes for an excellent display in engineering and general use, offering the clarity and color accuracy needed for detailed work. However, its lower refresh rate could lead to less smooth visuals in fast-paced gaming and 3D tasks. On the other hand, the Lenovo Flex 5 14 offers decent visual quality for everyday tasks and engineering, with fair color reproduction and resolution, but also falls short for gaming and 3D usage due to its modest refresh rate.

How the ASUS ROG Strix Scar 15 and the Lenovo Flex 5 14 compare to other laptops
"Asus continues to refine the ROG Strix Scar lineup with new upgrades. The Asus ROG Strix Scar 15 offers almost everything you would expect from a gaming laptop at this price. The build quality is great, connectivity options are decent, and there is enough scope for internal upgrades as well. Asus reverts to membrane switches for the keyboard — though not as "clickety" as the opto-mechanical ones we saw with last year's model, they still make for a decent typing and gaming experience. The lack of biometrics in any form is a downer."
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
