Selling my Pre-owned Koorui Gaming Monitor Brand: KOORUI Refresh Rate: 170Hz Resolution: 2560 x 1440p Screen size: 27" inch Color: Black Speakers: No (External Audio sources e.g. Aux, HDMI etc) I'm only selling this because I'm upgrading to a new 4K Monitor because I got a new high end Gaming pc to match 4K Resolution for Gaming. I originally bought it for £220 and selling for £110, BARGAIN!!!!
