  • Best for: Competitive and fast-paced gamers who prioritise smooth motion and deep contrast
  • Not ideal for: Users who rely on USB-C single-cable workflows, listed inputs are HDMI 2.0 and DisplayPort 1.4

27-inch QHD Fast VA monitor with Mini LED local dimming and a 180Hz refresh rate. Height-adjustable stand supports longer sessions with a comfortable viewing position.


Ultra-smooth competitive play, with 180Hz refresh rate

A high 180Hz refresh rate updates the image 180 times per second, reducing the gap between rendered frames and displayed frames. Faster refresh restores small, rapid movements that lower refresh rates can miss.

Smoother motion makes fast target tracking and quick camera turns easier, giving a perceptible edge in competitive matches.

Minimal motion blur, thanks to 1 ms GtG response time

A 1 ms Grey-to-Grey response measures how quickly pixels change between grey levels, cutting down on trailing and ghosting. Faster pixel transitions preserve crisp edges during rapid on-screen movement.

Clearer visuals during fast action help maintain target clarity and reduce distraction from smeared motion.

Punchy contrast and bright highlights, with Mini LED and HDR1000

Mini LED backlighting uses many local-dimming zones (336 zones here) to adjust brightness per area, while HDR1000 certification means peak luminance up to 1000 cd/m² for strong highlights. Fast VA panel technology enhances black levels for deeper contrast.

Dark scenes look richer and bright effects pop, improving immersion in HDR-enabled games and films.
