Medion Signium 27 S1: 27-inch upgradable AIO for £750

Medion has launched the Signium 27 S1, a 27-inch all-in-one desktop priced at about £750 and announced via the company’s UK press channels. The system ships with an Intel Core i7-240H processor, 32GB of dual-channel DDR4 memory and a 1TB PCIe NVMe SSD, and it includes internal expansion options for additional storage and memory.

The display is a 27-inch IPS panel with a 1920 x 1080 resolution, measured peak brightness near 240 cd/m2 and a contrast ratio of about 978:1. Color coverage on the review unit measured roughly 126.5% of sRGB, 89.6% of DCI-P3 and 87.2% of Adobe RGB. Native refresh rate is 60Hz at Full HD; an overdrive mode can reach 75Hz only at a reduced 1080 x 720 resolution. The panel has a matte anti-reflective finish and bezels of about 15mm at the top and bottom.

The chassis uses a silver-painted plastic enclosure with a slim two-piece metal stand. The assembly weighs about 3.8 kg and offers tilt adjustment from –20 to +40 degrees. There is no height adjustment, rotation or native VESA mounting. Three LED-lit rubber buttons under the display control power, input/brightness and a hardware webcam disable; the webcam includes a manual privacy shutter.

Ports include two 5Gbps USB ports on the right (one Type-A, one Type-C). On the rear panel Medion provides a 10Gbps USB-A, two USB 2.0 Type-A ports, a second Type-C that supports 10Gbps data plus DisplayPort output and USB Power Delivery, gigabit Ethernet, HDMI-in and HDMI-out (both 1.4), a 3.5mm audio jack, a Kensington lock and the DC input for the 120W power brick. Wireless connectivity is handled by an Intel AX211 card with Wi‑Fi 6E and Bluetooth 5.3. Medion includes a rechargeable keyboard and mouse that connect via a 2.4GHz USB dongle; the keyboard uses a full-size layout without backlighting, and the mouse has a low-profile shape.

Removing two Phillips screws on the rear reveals internal access to two SODIMM slots, space for a second M.2 2280 SSD and a bay for a 2.5-inch SATA drive. The review configuration used a 10-core Core i7-240H Raptor Lake Refresh mobile CPU, a PCIe 4.0 NVMe SSD and 32GB of RAM. In a 4K Handbrake multimedia test the system returned 221 points. Geekbench 6 scores were about 2,605 single-core and 10,341 multi-core. The integrated Intel UHD graphics produced roughly 15 fps in the SPECviewperf 3dsmax test. Sequential SSD read and write speeds measured around 3,855 MB/s and 3,027 MB/s in the review sample.

Cooling relies on a single fan. Under sustained load the fan maintained CPU and GPU operation without observed thermal throttling and ran quietly in the reviewer’s tests. Built-in audio comes from two down-firing speakers with a measured peak of about 69 dBA at 1 meter and limited low-frequency output. The 1080p webcam delivered low-detail images and does not support Windows Hello facial authentication or Windows Studio camera effects due to the absence of an on-device neural processing unit.

The Signium 27 S1 ships with Windows 11 Home and the review unit installed Ubuntu 24.04 without major driver issues. The unit’s factory configuration includes 1TB of SSD storage and 32GB of RAM, and the internal layout allows later upgrades to additional M.2 storage, RAM or a 2.5-inch drive.
