The choice of your monitor is just as important for gaming as any other hardware that you could possibly have within your CPU. Yes, it’s vital that you get a GPU that can support the highest settings in any games that you want to play, but if you don’t couple it with an excellent monitor, you certainly wouldn’t be able to experience the colors and clarity that the game is originally intended to be played in.
For instance, let’s take a look at an ordinary Samsung 22″ TN display. Sure, it works well enough for casual gamers who probably wouldn’t be able to tell the different between a 60 Hz and 144 Hz monitor. If you were to compare it to say a Dell UltraSharp U2312HM monitor, the differences are tremendous indeed. Both displays have similar sizes and both have an aspect ratio of 16:9. What causes the Dell to be significantly better than the Samsung monitor is the type of panel as well as the general build that it comes with. The U2312HM has an IPS panel, and a pixel pitch of 0.27mm. The resolution of the Dell monitor matters little here because practically every monitors that are 22″ and above will be capable of displaying 1080p resolutions.

Though that may be the case, the color that the Dell monitor is able to produce is simply jaw-dropping in comparison to the Samsung. Many gamers have attributed this to the fact that the Dell uses an IPS panel whereas the Samsung has a TN panel. Arguably though, a comparable BenQ XL2420T performs significantly better than the Samsung monitor despite having similar specs. Is its price justified? Sure. With a much higher maximum refresh rate of 120 Hz, coupled with a nominal response time of only 5 ms, you would certainly expect the BenQ to perform much better than Samsung’s 15 ms display. Input lag-wise, the BenQ trumps any other gaming monitors that are 24 inches and higher.
If personally given a choice here, I would still stick with the Dell for the reason that I’m not a professional twitch gamer who competes in top-level FPS matches. I’m more of a Civilization kind of gamer (with perhaps some strategy games like Starcraft thrown in), so it matters not that I can achieve a 120 or higher refresh rate on my monitor. The images will pretty much look the same to me. I rather have the capability of displaying 1440p resolutions on my monitor that I can look at the whole day while marvelling about it to anyone who would hear me out.
As far as gaming monitors go, 1440p IPS displays are way better than 1080p TN displays even with the lack of responsiveness and fluidity. If you ever get a chance to compare 2 gaming monitors with these stated specifications in your local shop though, I’m confident that you’ll arrive at the same conclusion that I have.
