What's the best gaming monitor?
PC gamers put heavy demands on a monitor. The games are visually complex, so large, high-resolution displays are required for realistic game play. Imagery changes rapidly thanks to highly advanced graphics processors (GPUs), so it’s important that the monitor can keep up to avoid frame disruptions. And the games are competitive -- even a minor glitch due to an ill-matched monitor could cost a player his or her virtual life.
This FAQ addresses some of the most important factors to consider before buying a gaming monitor. Especially for new gaming monitor shoppers, this guide will help you select the right display for you.
What to consider when buying a monitor for gaming
There are several factors to consider before buying a new monitor for computer gaming.
How does a monitor affect game performance?
With so much action centered on the controller or keyboard in the player's hands, it's easy to forget that each wrist and finger movement is dictated almost entirely by what can be seen on the monitor. If the display freezes or skips at a critical time, or if blur makes precision aiming impossible, a player could get knocked out of the game quickly.
Top monitor specs for gamers
Four standard monitor specifications are of special interest to gamers:
It's possible to play games on a standard HD monitor (720p), but most gamers demand at least Full HD (1080p) for sufficient clarity, aiming, and so on. Gaming monitors with QHD (1440p) and UHD (2160p) resolutions are also available, but need to be paired with advanced GPUs to get the most out of these high-resolution screens.
For gaming in general, the minimum refresh rate (i.e. how quickly the display can change the color of an individual pixel) is 60Hz. But 120Hz is far superior for competitive players, particularly if the game is in 3D.
There are also 144Hz models that many gamers prefer, not just for the slightly faster rate but because it maxes-out the refresh capabilities of DVI-D connections carrying 1080p video, a popular combination. Monitors with 240Hz refresh rates are available but gamers debate their value, with some appreciating the extra game-action precision and others deciding that 120Hz or 144Hz is perfectly suitable for the games they play.
Everyday monitors are sufficient if they offer response times (i.e. the time it takes to move from one still image to the next) in the 6-8ms range. Gamers typically demand response times of 5ms or less. Models with response times as low as 1ms are available for the hardcore gamer, but pricey.
Unless you're buying a new monitor and game box or gaming PC at the same time, the connection option you choose for your gaming monitor will need to match the output(s) of your existing system. The typical options, which vary by manufacturer, are HDMI, DVI-D, and DisplayPort. A newer, multi-functional connection option, USB Type-C (USB-C), is also being offered and can transmit signals compatible with the earlier formats without the need for adapters.
Solutions for tearing and stuttering
Gamers are vexed, in particular, by two troublesome monitor performance issues:
Tearing occurs when a single frame shows parts of two or more different frames. Tearing is sometimes caused when frames-per-second (FPS) performance drops below the standard 60 FPS required to smoothly display on-screen action.
The generation of new frames is sometimes disrupted by slow rendering (or other processing problems), but the monitor continues to refresh at its standard rate, causing frames that appear to repeat or get skipped. This is referred to as stuttering.
Generally speaking, tearing and stuttering diminish as the refresh rate of a display increases, but the problems still persist even in rapid-refresh models. Manufacturers have designed adaptive synchronization solutions such as AMD FreeSync and Nvidia G-Sync to help combat these problems. In simplest terms, these technologies force the monitor to adapt its refresh rate and other settings, on the fly, to meet the performance of the GPU, rather than refreshing at the standard rate and potentially creating visual disruptions.
Be aware, however, that FreeSync and G-Sync are specific to the GPUs of their manufacturers. So, if you're matching a new monitor to your existing PC, make sure the synchronization technology you choose matches the AMD or Nvidia GPU you are using.
