Dell offers several display configurations, including a standard 250-nit 45% NTSC anti-glare panel, a 250-nit touchscreen version and a higher-end 400-nit 100% sRGB ComfortView Plus panel.

For this ecommerce listing, the display should be advertised as 15.6-inch FHD IPS unless the exact SKU confirms the brightness, colour gamut and touchscreen configuration.

Professional Mobile Workstation

Precision is Dell's professional workstation family. The Precision 3591 is designed for users who need reliable performance for professional workloads such as engineering, software development, business analysis, technical applications and other demanding tasks.

The workstation can also be configured with professional NVIDIA RTX graphics. Dell lists the RTX 500 Ada Generation, RTX 1000 Ada Generation and RTX 2000 Ada Generation as discrete GPU options.

Important: Because your product specification does not mention an NVIDIA GPU, this listing does not claim that a dedicated RTX graphics card is installed.

Thunderbolt 4 Connectivity

The Precision 3591 includes two Thunderbolt 4 USB-C ports with USB4, DisplayPort 2.1, Power Delivery and data-transfer capabilities.

Thunderbolt 4 supports transfer speeds of up to 40Gbps and can support up to two 4K displays or one 8K display under supported configurations.

This makes the workstation suitable for connecting:

• Docking stations
• External monitors
• High-speed storage
• Professional peripherals
• USB-C accessories
• External displays

Extensive Professional Connectivity

The Precision 3591 provides a strong selection of physical ports, including USB-A, Thunderbolt 4, HDMI 2.1, Gigabit Ethernet, audio and microSD connectivity.

This allows users to connect to office networks, projectors, monitors, storage devices, wired accessories and other professional equipment without relying entirely on adapters.

Business-Ready Wireless Connectivity

The Precision 3591 supports modern wireless networking options including Intel Wi-Fi 6/6E and Realtek Wi-Fi 6 depending on configuration. Bluetooth connectivity is also available on supported wireless modules.

Optional WWAN configurations are available for selected systems, providing mobile broadband connectivity where supported.

Expandable and Serviceable Design

Unlike many thin consumer laptops with soldered memory, the Precision 3591 uses two SODIMM memory slots. This allows supported configurations to be upgraded up to 64GB. The system also supports removable M.2 SSD storage.

This makes the Precision 3591 a practical choice for businesses and professionals who want a workstation with room for future upgrades.
