27-inch business all-in-one

The Dell OptiPlex 7770 integrates a 27-inch Full HD IPS InfinityEdge display with a 9th Gen Intel Octa-Core i7-9700 processor, 32 GB DDR4 memory and a 256 GB SSD. It ships with Windows 11 Pro and includes a USB keyboard and mouse for immediate deployment in office environments.

Included peripherals and connectivity

A USB keyboard and mouse are supplied in the box, removing the need for separate accessory purchases. The chassis provides three USB 3.1 Gen1 ports, one USB Type-C Gen2 port, two USB 3.1 Gen2 ports, a DisplayPort output, a 3-in-1 SD card reader, Gigabit Ethernet, Wi-Fi and Bluetooth 5 for flexible peripheral and network connections.

Suited for standard office workloads

This all-in-one fits workers who need a compact, ready-to-use system for productivity applications, video calls via the integrated HD TrueVision webcam and multi-monitor setups through DisplayPort. Buyers who want more storage, discrete graphics or user-upgradeable components should look at something else.
