The big brother of the 24-inch test winner takes the price-performance victory in the 27-inch category. Gamers can also look forward to a frame rate of 180 Hertz and short switching times on the AOC 27G4XE. The maximum brightness is low and the AOC can only be tilted. However, you can hardly get a 27-inch gaming monitor for less: the price is 169 euros.
