27" AOC U27G4R
The AOC U27G4R gaming monitor uses Fast IPS technology and offers an advanced dual mode. This mode allows you to switch between a sharp 4K UHD resolution (3840×2160) at a 160Hz refresh rate and a competitive Full HD resolution (1920×1080) at a 320Hz refresh rate. This means the monitor delivers both detailed visuals for work and single-player titles, as well as extreme smoothness for e-sports. Support for G-Sync Compatible and FreeSync Premium adaptive sync eliminates screen tearing. All settings, including game modes, can be managed via the AOC G-Menu software.

Flexible Display with Dual-Mode Function
The AOC U27G4R monitor offers a Dual-Mode function to switch between 4K resolution at 160Hz and Full HD at 320Hz. This flexibility provides the best settings for detailed work and competitive gaming. A Fast IPS panel with a response time of 1ms (GtG) and 0.5ms (MPRT) in UHD mode reduces motion artefacts. The PiP and PbP functions display content from multiple sources simultaneously on one screen, which increases productivity when multitasking.

The AOC U27G4R features a Fast IPS panel with a native 4K UHD resolution of 3840 × 2160 pixels. The refresh rate at this resolution is 160Hz, increasing to 320Hz in Full HD mode. Extensive colour coverage of 124.7% sRGB and 93.4% Adobe RGB offers vivid and true-to-life colours for graphic design and gaming experiences. Support for the VESA Certified DisplayHDR™ 400 standard enhances contrast and the dynamic range of the image.
Full Monitor Ergonomics
The AOC U27G4R monitor stand offers complete adjustable flexibility. You can adjust the height within a 130mm range, tilt the screen forwards and backwards, or swivel it sideways. The pivot function allows you to rotate the screen 90 degrees to a portrait orientation, which is practical for working with code, documents, or for specific streaming setups. These positioning options help to reduce neck strain during long-term use. For alternative installation, the monitor includes a 100 × 100mm VESA interface.

Colour Gamut
Determines how accurately the monitor can display colours. sRGB is ideal for the web, films, or games. DCI-P3/Adobe RGB will be appreciated by graphic designers or professionals at work. The higher the stated value, the better the monitor displays colours. Maximum Brightness
The value, given in nits or cd/m², determines the brightness level of the monitor. A brightness above 400 nits is key for HDR content and readability in sunlight, while standard office monitors are sufficient with values above 250. Refresh Rate and Response Time
The refresh rate (Hz) determines the number of frames displayed per second, so the higher the value, the smoother the image and the less eye strain. A lower response time (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
