The Lenovo ThinkPad T14 has a better screen than the Dell Inspiron 16 5635 for general use, engineering and design, content creation, and software development.
For general use, the Lenovo ThinkPad T14's screen boasts higher resolution and better brightness, making it well-suited for everyday tasks and multimedia consumption, compared to the Dell Inspiron 16 5635, which offers satisfactory visuals but doesn't stand out. Designers and engineers will find the ThinkPad T14's wider color gamut, covering more of the DCI-P3 and Adobe RGB spectrums, essential for precision in color-critical work, an area where the Inspiron lags behind. When it comes to gaming and 3D applications, however, both laptops fall short due to their mediocre refresh rates, although the T14's better resolution and panel type give it a slight edge for less demanding graphic tasks.

UltrabookReview
Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."

"We like a lot about this laptop. It has many ports, with the inclusion of RJ45-Ethernet as a defining feature. WWAN is upgradable for maximum flexibility and the ThinkPad has many security functions. Working with the ThinkPad input devices is a lot of fun, and Lenovo puts in a serviceable Low Power panel. The AMD Ryzen 7 Pro 7840U delivers a great performance and does not drain the battery fast. Fan noise and temperatures are nothing special, but also far away from bad. With the user replaceable keyboard, the ThinkPad T14 Gen 4 has a special feature rarely present on most modern laptops."
