1440p Gaming Monitor
Asus offers gamers the best 1440p gaming monitor at the price of 800 euros. It’s the first screen to hit the 2560 x 1440 native resolution along with a 1ms pixel response time and the full 144Hz refresh rate. The monitor has a panel size of 27-inches and it is able to run G-Sync. Although this monitor is top quality, it still has some negative sides to it. It is very expensive (800 euros) and it requires an Nvidia graphics card in order to run to use G-Sync.
1080p Gaming Monitor
One of the best 1080p gaming monitors out there is the Viewsonic VX2263SMHL. This 22-inch screen has a native resolution of 1920 x 1080p along with a 5ms pixel response time and it costs 160 euros. The reason this monitor is popular is because the screen has vibrant colours and great viewing angles. However, the monitor does have a few downsides. It is limited to 60Hz refresh rate and it is not compatible with G-Sync.
4k Gaming Monitor
The very first 4K monitor with G-Sync built in, is the Acer XB280HK. This monitor offers a panel size of 28-inches with a native resolution of 3840 x 2160 along with a pixel response of 1ms. The monitor is relatively affordable at the price of 600 euros. However, 4K monitors come with a lot of downsides. First of all, they require a huge amount of rendering power to game at a decent frame rate. For example, the GTX 980 struggled to hit 36FPS at Ultra 4K settings in battlefield 4.
Monitors and Competitive Gaming
In the competitive scene of gaming, monitors usually do not play a huge role unless it is a First Person Shooter. Games like Smite, LoL and Starcraft 2 play on monitors with 60Hz refresh rate because they do not need high-end quality or extreme smoothness to improve their gameplay.
First Person Shooters are usually played on monitors with 144Hz refresh rate. The reason behind this is that with a higher refresh rate, the game becomes a lot smoother and therefore enhancing the gamer’s gameplay. However, there is a downside to this. If the FPS of the game is lower than the refresh rate on the monitor, they will get screen tearing. To conclude this idea, it is better to play first person shooters on a monitor with a refresh rate of 144Hz as long as the frame rate is above 144. (https://goo.gl/8n3rZE)
