The Dell Precision 7720 (Model 7720), released in 2017, was billed by Dell as "the world's most powerful mobile workstation" of its generation — a full-size 17.3-inch mobile workstation built for professionals like engineers, 3D artists, video editors, CAD designers, and VR developers who need desktop-class power on the move. It carries the regulatory model number P29E, and its magnesium-alloy chassis with a carbon-fiber lid pairs Intel Core and Xeon processors with professional-grade NVIDIA Quadro or AMD Radeon Pro graphics and ISV-certified reliability. Dell shipped the 7720 across two processor generations in the same chassis — 6th-generation "Skylake" and 7th-generation "Kaby Lake" Core and Xeon chips — and let buyers heavily customize it at checkout, so your exact combination of parts determines its final resale value. Many people don't realize a used workstation like this still holds strong value, and that you can turn it into cash in a few days without the hassle of eBay listings, lowball offers, or shipping-heavy marketplace meetups.

Display & audio
Display
All are 17.3-inch 16:9 anti-glare panels. The standard option is FHD (1920 × 1080) IPS at 72% color gamut. The premium option is a 4K UHD (3840 × 2160) IGZO PremierColor panel with 100% Adobe RGB color coverage — ideal for photo, video, and design work. The 4K PremierColor display is the most desirable and raises resale value, so it's worth confirming which screen you have.
