iiyama G-Master GB2766HSU-B1 27" Curved 165Hz FHD Monitor
The iiyama G-Master GB2766HSU-B1 is a 27-inch curved gaming monitor built for competitive players who demand smooth, responsive gameplay without tearing or stuttering. Its 165Hz refresh rate, 1ms response time and AMD FreeSync Premium synchronise your graphics card output with the display, eliminating the visual artefacts that cost matches.
Why this product
1500R curve wraps your view
The curved VA panel sits at a 1500R radius, matching the natural arc of human vision. This reduces head and eye movement during long sessions and deepens immersion in first-person and racing titles.
165Hz and 1ms for competitive play
The 165Hz refresh rate and 1ms MPRT response time combine to deliver fluid motion and minimal ghosting. AMD FreeSync Premium locks the refresh rate to your GPU output, eliminating tearing at any framerate between 48Hz and 165Hz.
Black Tuner darkens shadow detail
This customisable function lifts detail in dark scenes without washing out highlights, giving you sight lines in poorly lit game environments.
Fully adjustable stand
Height slides 130mm, tilt swings from -5° to 22°, and VESA 100×100mm mounting is available. Dial in your ideal viewing angle for marathon sessions.
