Considering the Dell Inspiron 15 3511 and LG Gram 17, the Dell model will save you money, but the LG Gram offers a larger screen with higher resolution, which is better for multimedia and productivity tasks. The LG Gram is also lighter, making it more portable, and it has a longer battery life for on-the-go use. The Dell has a mid-range processor that's suitable for everyday tasks, while the LG’s higher-end processor provides better performance for demanding applications like video editing or programming. If price is your main concern and you require a machine for general use, Dell is a practical choice. If you are looking for a balance between performance, screen size, and portability — and don't mind spending more — the LG Gram may be the better option. Give Feedback

The LG Gram 17 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Dell Inspiron 15 3511's screen might not deliver the sharpest image or the best viewing angles, as it lacks a high resolution and an IPS panel, but the LG Gram 17 offers a higher resolution and better panel type for crisper images and wider viewing angles, along with superior brightness. In engineering and design workflows where precise colors are crucial, the LG Gram 17’s ability to display a wider color spectrum ensures more accurate color representation, whereas the Dell's color range may fall short. For gaming and 3D applications, both the Dell and the LG Gram suffer due to lower refresh rates, which may not provide the smooth visuals required for fast-paced scenes, but the LG's higher resolution and better panel still offer a more pleasant visual experience for less demanding games.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"The LG Gram 17 is a light office laptop with a large display and great battery life. The newest incarnation of the Gram 17 can be classified as a model update. LG uses the predecessor's compact, light magnesium case along with an identical port configuration (including 2x Thunderbolt 4) and keyboard. Changes can be found in the hardware. With the Gram 17 (2022), LG offers a light (approx. 1,350 g), mobile work device - and finally with a matte display."
