This gives an excellent ‘connected feel’, which describes the precision and fluidity felt when interacting with your character and the game world.
The responsiveness of the monitor was also quite impressive – which is a good thing given that it’s a key focus of 240Hz models like this.But we appreciate some users still like to use profiles and some aspects such as gamut mapping for colour-aware applications can be useful. When the frame rate rises above 240fps, the monitor will stay at 240Hz and the GPU will respect your selection of ‘VSync on’ or ‘VSync off’ in the graphics driver. 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.
The subpixel layout and arrangement is normal and we had no subpixel-related concerns related to sharpness or text clarity on this model. Although this won’t correct uniformity issues, profiling the monitor with your own colorimeter or spectrophotometer is always advised for best results if the strongest colour accuracy is desired.Some isolated weaknesses such as bright markers or strongly illuminated objects against some shaded backgrounds leaving a ‘powdery’ trail – but as with our observations in BFV this wasn’t really a major weakness.
Firing up Doom Eternal for a quick blast, I was impressed with how fluid and clear everything looked onscreen. There’s no strobe backlight mode on this model, but they come with their own compromises that not everyone is willing to make. The included stand can be removed using a hexagonal quick-release button beneath the attachment point and replaced with an alternative 100 x 100mm VESA compatible solution, if preferred. For the lowest levels of perceived blur it’s also important that the monitor performs its pixel responses rapidly. That’s a little on the low side for a modern IPS monitor but on the money for what Dell is claiming for the screen.The letters ‘PCM’ are typed out to help highlight any potential text rendering issues related to unusual subpixel structure, whilst the white space more clearly shows the actual subpixel layout alongside a rough indication of screen surface. You can see relatively minor shifts in contrast and colour for the mixed desktop background and game scene.
The colour gamut of the AW2521HF (red triangle) was compared with the sRGB reference colour space (green triangle), as shown in the image below. When responding to an input, the AW2518HF was measured (by Tom’s Hardware) to have an absolute (end-to-end) input lag of just 19 ms, which is incredibly low. The ‘Fast’ setting only showed a relatively small amount of this, whilst the ‘Super Fast’ and ‘Extreme’ settings ramped this up. ports situated behind the bottom edge of the monitor facing down, plus two USB 2 ports, a pair of USB 3 ports and a 3. A very slight ‘shadowy’ trail behind the UFO, but overall rather similar to the ‘Fast’ setting in appearance.Even Nvidia’s popular high mid-end option, the GeForce RTX 3080, was only able to average 186 FPS in these benchmarks. The chunky stand offers 130mm of height adjustment, plus the ability to tilt by -5 and 21 degrees, swivel by 40-degrees left and right, and pivot all the way around into portrait view. This worked exactly as it’s designed to, removing tearing and stuttering by ensuring the refresh rate stuck to a multiple of the frame rate.
