ASUS MG278Q 27 Inch WQHD 1440P 144Hz Gaming Monitor

£506.00

This is actually a relatively old model, but it sells extremely well because it has a fantastic 144Hz refresh rate and is pretty much the perfect monitor for semi-pro gamers.  It includes Freesync support too.  For a really great monitor, for fast moving games, then look no further.  Detail is great with the 2560 pixels by 1440 pixels high resolution.
