27" business all-in-one

The Dell OptiPlex 7770 combines a 27-inch Full HD IPS display with a 9th Gen Intel Core i7-9700 processor, 32 GB of DDR4 memory and a 1 TB solid-state drive. Windows 10 Pro is pre-installed and a USB keyboard and mouse are included. The integrated Intel UHD Graphics 630 drives the 1920 x 1080 panel, while Gigabit Ethernet, Wi-Fi and Bluetooth 5 handle connectivity.

Upgrade from older integrated desktops

This unit replaces earlier all-in-one systems that rely on dual-core processors, mechanical hard drives or smaller screens. The eight-core CPU and solid-state storage cut boot and application load times, and the 32 GB memory ceiling supports heavier multitasking. The jump is worth it when daily workloads involve large spreadsheets, multiple browser sessions or video conferencing on a single desk footprint.

Suits office and reception deployments

The compact form factor fits reception counters, shared workstations and home offices where a separate tower and monitor would add clutter. Buyers who need discrete graphics for 3D rendering, colour-critical work requiring a wider gamut, or user-replaceable components should consider a traditional desktop chassis instead.

Questions about this item

Will the 27-inch 1920 x 1080 display fit on a standard VESA 100 mm mount?

The 27-inch 1920 x 1080 panel is built into the chassis; the unit ships with Dell basic, articulating, or height-adjustable stands that tilt, swivel, and pivot for desk mounting.

Which screw or latch releases the rear cover so I can upgrade the 32 GB DDR4 SODIMM memory?

Remove the single captive thumbscrew at the bottom of the stand neck, then lift the rear cover straight up to expose the two 204-pin DDR4 slots for memory upgrades.

When the 1 TB 2.5-inch SSD reaches end of life, what replacement drive type should I order?

Order another 2.5-inch solid-state drive; the internal bay accepts standard 2.5-inch SSDs, and the installed Windows 10 Pro will recognise the new drive after a clean install.
