The process of PC buying and building is full of jargon and that doesn't stop when it comes to choosing a monitor. There are some key data points to consider when choosing the display, and it's important to understand them before you drop your money. One such piece of potentially confusing information is response time. Here, we'll help you cut through the jargon and try and make the right decision for your setup.

What is monitor response time?

This definition provided by a member of the Overclock forums describes it perfectly:

Response time is how quickly the display can have a LCD pixel to change from fully active (white) to fully inactive (black), then back to fully active again. A lower response time typically means less ghosting of the image and better picture quality.

This differs from refresh rate, which is how many times per second the panel can redraw the image. With refresh rate you want a higher number, response time you want to go lower. It's measured in milliseconds, so a five-millisecond (5ms) response time means that a monitor can go from white to black to white in 1/200th of a second.

Getting the lowest possible response time will ensure image ghosting is minimized, leaving you with overall better clarity and quality.

The best monitors for PC gaming

When you need to game on your PC, you need a gaming display that can handle all the pixels sent by your GPU. Adding synchronization technology to the mix really makes your game catalog shine, no matter what you play. Depending on what GPU you own and how much budget is available, we have the best recommendations for different resolutions.

So just get the lowest?

Yes and no. Like refresh rate, response time will vary depending on manufacturer and what type of monitor you're getting.

Gamers will traditionally want the lowest possible response time, and 1ms monitors are commonplace, particularly in esports. What you don't want when you're gaming is image ghosting interfering with your experience. You want the sharpest picture you can get.

There are some great, inexpensive gaming monitors out there with a 1ms response time, like the BenQ RL2455. It costs under 200, has a 1ms response time, can have up to a 75Hz refresh rate, and is a solid all-rounder for PC and console gaming.

Top class gaming on a budget

This is a great monitor for PC or console at any price point, with a crazy low 1ms response time, up to a 75Hz refresh rate and optimized presets for various different game types.

If you're looking at higher resolution panels like 1440p, Dell's S2417DG with NVIDIA G-Sync is a great shout. It's got both a low response time and a very low input lag.

An amazing monitor at an attractive price

With this monitor you get a 1ms response time, low input lag, a 165Hz 24-inch 1440p panel, and NVIDIA G-Sync for tear-free gaming. It ticks all the boxes at a really great price.

But, response time is but one feature to consider when buying a monitor. Refresh rate and input lag are always advertised, but input lag is something else important, and not to be confused with either of these things.

Unfortunately, the performance of your monitor is still at the whim of the manufacturer actually producing it. In theory, the lower response times should always be better and reduce image ghosting, but the type of panel used and its quality will still be a factor.

A bad monitor will still be a bad monitor.

What's important to point out is the difference between response time and input lag. Response time is how quickly an image can be displayed, input lag is how long it takes the monitor to react to an action you performed. If you have a one-millisecond response time, it's no guarantee of a great gaming experience if the input lag is too high.

Imagine you're playing a competitive shooter like CS:GO or Call of Duty. You've got a low response time for ghost-free, sharp images, but if you move the mouse or your controller and there's a noticeable delay between that action and the in-game equivalent, you've got high input lag and the experience will be tainted.


Ideally, you want a balance of three things in your gaming monitor: low response time, high refresh rate, and low input lag. Console gamers don't have to be as concerned with refresh rate right now, but a good gaming monitor like the BenQ RL2455S will provide a 1ms response rate for great quality images, a low input lag and will handle 60FPS gaming with ease.

PC gamers have a little more to consider, especially for targeting high frame rates. There is a lot of choice now though, with high refresh rate monitors more common than ever and many will also come with a 5ms or lower response time. The Dell S2417DG is a fine example of a well-balanced monitor that covers all three of the holy trinity of features.
