About this model
Text from the manufacturer, via Icecat.
Immerse yourself in the curve and outpace the competition. Standard flat panels can leave you feeling disconnected from the action, with motion blur and low contrast masking your targets. The G-MASTER GC2781HSU changes the game with a 1500R curved VA panel that matches the natural field of human vision, pulling you deeper into the world while offering a superior static contrast ratio for the black depth. Combined with a 144Hz refresh rate and 1ms MPRT, it eliminates ghosting and screen tearing, ensuring that every movement is fluid and every enemy is visible, even in the darkest corners of the map.
