When you already have a normal computer monitor at home, would you really need a monitor for gaming? A gaming monitor keeps in mind the fact that your games would need higher graphics performance and better frame rates to do justice to the game software and display.
There are several aspects of the gaming monitors that make them stand out of crowd. Twisted Nematic displays, IPS displays, VA displays, there are many such display technologies to pick from. Each comes with its own strengths and shortcomings.
Then comes the refresh rates of the monitor. Several games these days offer more than 60 frames per second. So a monitor that comes with refresh rates of a minimum of 144Hz would suit these games better.
Another factor that gamers see is the FreeSync and the G-Sync feature. Choosing one depends on the type of graphic card you have. Each works best with different types of graphic cards. G-Sync versions also might be a bit expensive than the FreeSync ones. And FreeSync monitors offer smoother displays by removing tearing in the display.
Look for a higher resolution monitor. This would come with larger pixels which offer more details. So in addition to the display panel technology the size of the monitor and the display resolution also matter.
There are other additional features found in gaming monitors like the reduction in the motion blur and the overdrive. Different monitors come with different overdrive and most of them do allow overdrive in the recent times. For action games, maintaining smoothness of the graphics would be essential. For this, a monitor with blur reduction would be required.
Other finer details that you can look for in your gaming monitor is the bit-depth and uniformity compensation. You could flex a little on your budget when it comes to gaming monitors as you really need the best one to deliver the best game-play experience.
