The Dell S2421HGF is a 23.8" gaming monitor that combines short response times with very high refresh rates to create an exceptionally smooth gaming experience. At the same time, it supports gaming-centric features like anti-tearing. With its Full HD resolution, it delivers detailed images and has moderate demands on your graphics card, making it a very good choice for mid-range gaming PCs. This monitor uses Twisted-Nematic (TN) technology, which excels with extremely short response times. High response times can lead to unsightly motion blur in fast-moving content, but the TN panel of this monitor is fast enough to prevent this effect. Thus, this monitor is an excellent choice for multimedia applications. Thanks to FreeSync, this monitor can synchronize its frame rate with that of your compatible graphics card, minimizing input lag and avoiding unsightly tearing effects. Unlike traditional solutions like VSync, this technology does not require a frame rate cap. With this monitor, you are doing your eyes a favor. The Flicker-Free technology prevents annoying screen flicker that can be tiring on the eyes. Not only unpleasant but even harmful is short-wavelength blue light, which has a similar effect on the retina as UV radiation. This Dell monitor features ComfortView technology, which filters out this light component.
