Quick Glance
Key Features
240Hz IPS with 1ms Response
A 27-inch Full HD IPS panel runs up to 240Hz with a 1ms (GTG) response time, keeping fast-moving scenes sharp instead of blurred. AMD FreeSync Premium and G-Sync Compatible support work with both AMD and NVIDIA graphics cards to reduce screen tearing and stuttering during gameplay.
HDR10 Certified Colour
The panel is HDR10 certified and reaches 400 cd/m² brightness with a 1000:1 typical contrast ratio, covering 99% of the sRGB colour space. IPS technology holds colour and contrast steady across wide 178°/178° viewing angles, so the image stays accurate even off-centre.
Height-Adjustable, Tilt, Swivel and Pivot Stand
The included stand adjusts height by 120.0mm, tilts from -3.0° to +22.0°, swivels from -15.0° to +15.0° and pivots from -92.0° to +92.0° into portrait orientation. A 100 x 100mm VESA mount is also built in for a monitor arm or wall bracket.
