27-inch business all-in-one

This Dell OptiPlex 7770 combines a 27-inch 1920 x 1080 IPS InfinityEdge display with a 9th Gen Intel Hexa-Core i5-9500 processor. It ships with 8 GB DDR4 SODIMM memory, a 128 GB M.2 SSD plus a 1 TB hard drive, and Windows 11 Pro. The integrated Intel UHD Graphics 630 handles everyday office workloads. A USB keyboard and mouse are included.

Check memory slots and drive bays before ordering

The system uses 204-pin DDR4 SODIMM modules and currently has 8 GB installed. The supplier notes configurations up to 64 GB are possible, so verify how many slots are free. Storage combines an M.2 SSD and a 2.5-inch hard drive; confirm the chassis has the required mounting points if you plan to swap either drive. Wireless and Bluetooth 5 are integrated.

Fits a compact desk with minimal cables

The all-in-one form factor removes the need for a separate tower and monitor, freeing desk space. Connectivity includes three USB 3.1 Gen 1 ports, one USB Type-C Gen 2 port, two USB 3.1 Gen 2 ports, DisplayPort, a 3-in-1 SD card reader and Gigabit Ethernet. The height-adjustable stand offers tilt, swivel and pivot. An HD TrueVision webcam and microphone are built in for video calls.

Questions about this item

Does the box include the USB keyboard and mouse, or must they be purchased separately?

The box includes a USB keyboard and a USB mouse, so no separate purchase is needed for basic input.

Should I choose the 8 GB DDR4 configuration or the 64 GB DDR4 option mentioned in the highlights?

The 8 GB DDR4 SODIMM is the installed amount; the 64 GB figure is the maximum the system supports if you upgrade later.

What does the 1920 x 1080 resolution mean on the 27-inch IPS panel in daily use?

It delivers Full HD clarity on a 27-inch screen, giving sharp text and video for office tasks without the scaling issues of higher resolutions.
