Acer 57" Predator Z57 7680x2160 120HZ 1ms Curved Ultrawide Monitor - RRP £2,199

Refresh Rate: 120Hz refresh rate for smooth gaming visuals and reduced motion blur. I bought this last year for use in my office, but it's just too big and occupies a lot of my desk. It's a beautiful monitor though, with amazing features but it is only sitting boxed up in storage.
