While it may not be the slimmest laptop on the market, it’s built to withstand the rigors of daily use in a business environment.

– **Materials and Finish**: The laptop’s casing is predominantly made of high-quality plastic, which offers a good balance between weight and durability. The finish is matte, which helps to reduce fingerprints and smudges—a feature appreciated by those who prioritize a clean, professional look.

### 2. Display: 14″ Touch LED

The **14-inch Touch LED display** is one of the key highlights of this model. This touch functionality can be particularly useful for professionals who prefer an intuitive interaction with their device, such as navigating presentations, scrolling through documents, or zooming in on graphs and images.

– **Resolution**: The display offers an **HD resolution (1366 x 768 pixels)**, which is fairly standard for this type of business laptop. While it doesn’t deliver the same sharpness as Full HD (1920 x 1080) screens, it’s still sufficient for most office tasks, including word processing, spreadsheets, and browsing the web. The screen is bright and offers decent color accuracy, though it’s not aimed at professional-level photo or video editing.

– **Touchscreen Functionality**: The addition of a touch-sensitive display is a huge plus for users who like hands-on navigation. It responds well to taps and swipes, making it a suitable choice for tasks like note-taking (especially if paired with a stylus), browsing through reports, or even casual entertainment like watching videos.

– **Viewing Angles and Brightness**: The display uses **LED backlighting**, which contributes to good energy efficiency. However, its viewing angles are somewhat limited due to the standard TN panel technology used.
