The best gaming monitor might offer a 144Hz refresh rate and 1ms response time at 1080p for a great price, or it might boast 4K resolution in an ultrawide format. There isn't a 'one size fits all' when it comes to monitors. Which genre of game you play the most, and what you really value in a screen, makes a massive difference. But a good monitor, just like the best gaming chair, has an incredibly long lifespan compared to many other components and peripherals, making it a great investment for your gaming setup.
There are serious questions you need to ask yourself first to narrow down your selection. Do you favour image quality over lightning-fast pixel response? Do you need Nvidia's G-Sync or AMD's FreeSync? Does it even matter now that Nvidia supports FreeSync?
Are you into the pro-gaming, competitive esports world and crave the super-high monitor refresh rates of TN tech rather than a quality panel? Do you want a traditional 16:9 screen or have you been seduced by the ultra widescreen beauty of a 21:9 aspect ratio? Do you need a monitor so wide you can almost see those Fortnite enemies standing behind you? Or does it absolutely, positively have to be the best 4K gaming monitor so you can spot each individual blade of grass in The Witcher 3? And, finally, how convinced are you by the prospect of high dynamic range gaming?
