The Lenovo IdeaPad Slim 7i Pro has a better screen than the Dell Inspiron 14 7420 for general use, gaming and AI, and engineering and design.
The Dell Inspiron 14 7420, with its fair screen quality, offers sufficient resolution and brightness for everyday tasks, but its limited color gamut might not provide the vibrant colors needed for detailed engineering and design work. The Lenovo IdeaPad Slim 7i Pro's very good screen includes higher resolution and superior brightness, making it appealing for both general use and professional design applications where color accuracy is critical. However, both laptops fall short for gaming and 3D due to their lack of high refresh rates, which are crucial for smooth visuals in fast-paced environments.
The Dell Inspiron 14 7420 and Lenovo IdeaPad Slim 7i Pro are both good for general use.
The Dell Inspiron 14 7420 offers a decent blend of performance with its i7 CPU and ample RAM for general use, a high-quality screen with moderate brightness and color coverage, and adequate battery life, all in a package that’s portable but a bit heavier than some competitors. On the other hand, the Lenovo IdeaPad Slim 7i Pro boasts a more powerful display including greater pixel density and brightness, a slight edge in battery life, and a lighter build enhancing its portability, but uses an i5 CPU which, while still capable for general tasks, places it a step behind the Dell in raw processing power.

The Dell Inspiron 14 7420 and Lenovo IdeaPad Slim 7i Pro are both only fair for gaming and AI.
The Dell Inspiron 14 7420 and Lenovo IdeaPad Slim 7i Pro are rated as fair for gaming and 3D mostly because both have integrated GPUs, which are not as powerful as dedicated graphics cards. However, the IdeaPad offers a bit better gaming experience with a higher screen refresh rate, presenting smoother visuals compared to the Inspiron's lower refresh rate.

Although they have very similar scores, PerfectRec considers Lenovo IdeaPad Slim 7i Pro to be good for engineering and design, while the Dell Inspiron 14 7420 is only fair.
The Dell Inspiron 14 7420 features a 10th Gen Intel i7 processor and a versatile 2-in-1 design useful for engineering and design, although a newer processor could offer better performance; the Lenovo IdeaPad Slim 7i Pro, with a higher-resolution screen and 11th Gen Intel i5 processor, excels in screen quality, but might lag slightly behind in processing power compared to the latest i7 chips. While both have solid build quality and good portability, the Lenovo offers a superior display for detailed design work, and the Dell's convertible design provides flexibility for different working scenarios.

How the Dell Inspiron 14 7420 and the Lenovo IdeaPad Slim 7i Pro compare to other laptops
"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
