Additional testing was performed using an AMD Radeon 580 and using HDMI, although observations for this table didn’t significantly vary between GPUs or inputs.There are some further customisable ‘AlienFX’ RGB LED features – an alien motif towards the top left and a large oval running along the inside of the stand neck.

It's a Freesync Premium screen at its core, but it's also one of Nvidia's fully certified G-Sync Compatible monitors as well, making it a great choice for AMD and Nvidia graphics card owners alike looking for smooth, tear-free gaming at high refresh rates.Firing up Doom Eternal for a quick blast, I was impressed with how fluid and clear everything looked onscreen.

This is an alternative to VSync which allows the frame rate to rise above the refresh rate (no VSync latency penalty) whilst potentially keeping the experience free from tearing or juddering. The 25-inch screen is flat and has barely any bezel, with only a thin black band running along three edges. A very slight ‘shadowy’ trail behind the UFO, but overall rather similar to the ‘Fast’ setting in appearance. It's a feature often touted as a 'must-have' for competitive multiplayer games to give you that extra 'edge' online - especially when said games are often the ones that can make the most of the AW2521HFL's 240Hz refresh rate.

Personally, I'm not particularly opposed to it either way, but it's definitely not as lovely as AOC's slim, black and red C27G2ZU.

This model is labeled as a FreeSync Premium monitor, but it is not advertised as an HDR display even if it passes DisplayHDR 400 standards. It’s great that you don’t have to flip the monitor or blindly reach for the slots at the rear panel if in case you want to swap between your peripherals. To maximise colour accuracy within the sRGB colour space, for colour-managed workflows, full calibration and profiling with a colorimeter or similar device is recommended.
