We put this monitor through its paces, seeing how it compares to the more common TN options such as the impressively responsive Acer XN253Q X. Adaptive-Sync support is included, allowing AMD FreeSync Premium and Nvidia’s ‘G-SYNC Compatible Mode’ to be used. The Dell Alienware AW2521HF (now designated AW2521HFA in UK and EU) aims to find a nice balance between speed and image quality, combining a 240Hz refresh rate with the superior colour quality of an IPS-type panel. The high refresh rate and frame rate combination can be particularly attractive for competitive gamers, but also appreciated by fans of less competitive fast-paced action.
