Alienware AW2521HFL Monitor vs LG 27GN950-B Monitor Comparison

Gaming monitors are now really on their way. Whether you are looking for a 4K gaming monitor or a 120Hz gaming monitor that is designed for the most smooth experience, you can find something to suit your exact gaming style. Apart from these extremes you can find a lot of value as well, and it is not only budget gaming monitors that we talk of, we mean the majority of monitors now have high-color depth VA or IPS panels with quick responses and nearly all are faster than 60Hz.

Alienware AW2521HFL

The speed of gaming monitors, and Alienware 25, as far as input lag and refresh rate are concerned, is some of the fastest we have seen yet. This 25-inch 1080 picture monitor has a single millisecond input layer at its highest level of refreshment that justifies its $509.99 list price. (Often a fair bit on has been discounted.) Moreover, the 240Hz refresh rate of the panel will delight all but the most discriminating types of sports, who thrill its flow to quick-twitch action games. It does not impress with its color performance (especially for movies), and it's adaptive-sync G-Sync Compatible feature hasn't worked as silky as native G-Sync can be.

LG 27GN950-B Monitor 

The LG 27GN950-B is a large 4k monitor for gaming. It has a high 160Hz refresh rate, but only a DisplayPort connection can allow you to achieve this refresh rate and a high-end graphical card needs to be used for this monitor to the full. HDMI 2.1 support is missing and can be connected with HDMI with only 4k@60Hz. Its incredible response time results in very clear motion and it also has an incredibly low input lag. It offers an incredible gaming performance. The system supports FreeSync variable radiation (VRR) and G-SYNC to minimize the tearing of the screen. It's quite good, but in terms of ergonomics it doesn't offer much as you cannot swivel.
