Built for business desks

The Dell OptiPlex 7770 is a 27-inch all-in-one desktop aimed at office users who want a single unit that includes the display, compute and peripherals. It ships with a USB keyboard and mouse and a fresh installation of Windows 11 Pro. The 1920 x 1080 IPS InfinityEdge panel provides Full HD clarity for documents and video calls.

Connectivity limited to integrated graphics output

Video output relies on the Intel UHD Graphics 630 engine, so external monitors can only be driven through the available DisplayPort connection. The system offers three USB 3.1 Gen 1 ports, one USB Type-C Gen 2 port and two USB 3.1 Gen 2 ports for peripherals. Gigabit Ethernet, Wi-Fi and Bluetooth 5 handle network links, while a 3-in-1 SD card reader adds removable-media access.

Replaces a separate tower

This configuration upgrades from a traditional desktop-plus-monitor setup by merging the 9th Gen Intel Octa-Core i7-9700 processor, 16 GB DDR4 SODIMM memory and a 2.5-inch 512 GB SSD into the display chassis. The jump is worth it for buyers who need a cleaner desk and simpler cable management. It is not for users who require discrete graphics performance or internal expansion slots.
