Gamers love chasing high refresh rate monitors for better motion clarity and smoother gameplay, especially in fast-paced titles. Of course, a 144Hz monitor will be better than a standard 60Hz panel, but that doesn't mean refresh rate is the only spec that matters for gaming. There's a reason we recommend some 144Hz monitors over others, and that usually comes down to response times. Despite identical refresh rates, two monitors can look very different during fast motion.

For motion to look crisp and clean, your monitor's response time has to keep up with the refresh cycle. If pixels take too long to transition between frames, you'll experience smearing and ghosting, which is just as distracting as motion blur. A higher refresh rate won't help you with slower pixel transitions. In fact, it tends to be more noticeable at higher refresh rates like 240Hz and 360Hz. That's why you should prioritize response times just as much as refresh rate, especially if you're getting an LCD monitor instead of an OLED.

Response time matters more for motion clarity

A higher refresh rate guarantees smoothness, not a clearer image during motion

Most people assume that a higher refresh rate automatically translates into better motion clarity, but without fast response times to match, it mainly makes motion feel smoother rather than sharper. Sure, the screen may refresh more often, but if pixels are still in the middle of transitioning when the next frame arrives, you won't get the sharpness you typically expect from a 144Hz or 240Hz monitor. Instead of crisp edges, you'll see faint trails and blurred outlines that make fast movement harder to track.

That's why smooth animation and clear motion aren't interchangeable. A higher refresh rate improves how fluid a game feels, but response time is that one spec that determines how clean it actually looks. If you get a 144Hz monitor that claims a 0.5ms or 1ms response time, you can expect it to be clearer than a panel that's limited to 2ms or 3ms. However, you should always take the advertised response times with a grain of salt because those numbers are often measured under ideal conditions using aggressive overdrive settings.

Refresh rate can't overcome smearing and ghosting

Poor response times can ruin clarity even at ultra-high refresh rates like 360Hz

You might think getting a 240Hz or 360Hz monitor would solve motion clarity issues by brute-forcing smoothness, but smearing and ghosting don't completely disappear just because the screen refreshes faster. At higher refresh rates, frame times shrink to just a few milliseconds, which leaves very little room for slow pixel transitions. If pixels can't transition quickly enough before the next frame arrives, the image overlaps and softens instead of becoming clearer. This is exactly why I prefer OLEDs over traditional LCDs for ultra-high refresh rate gaming.

OLED pixels transition almost instantly, which means they can keep up with extreme refresh rates without introducing the smearing and ghosting that still plague many LCD panels to this day. Sure, a 360Hz LCD monitor may claim a 0.5ms response time, but that pales in comparison to the sub-0.1ms response times OLED panels generally offer. And let's not forget that you need to use the fastest overdrive setting to get anywhere close to those advertised numbers on an LCD monitor, which introduces its own problems like pixel overshoot and inverse ghosting.

Response time is pointless on its own

But when refresh rate isn't a limiting factor, response time takes over

A fast response time doesn't mean much if your monitor's refresh rate is too low to take advantage of it. For instance, at 60Hz, your refresh rate is the limiting factor because each frame stays on screen for roughly 16.7 milliseconds. So, whether the response time is 1ms, 3ms, or even 5ms, pixels transition long before the next frame appears. At that point, motion clarity is constrained by how quickly new frames appear, not by how fast pixels can change state.

However, at 144Hz, a monitor with a 5ms average response time leaves very little room for error and can still compromise motion clarity. Keep in mind that the response time advertised on the box isn't what you'll actually get while gaming. Some transitions complete quickly, while others take significantly longer, especially in darker scenes on LCD panels. And when those slower transitions exceed the 6.94ms refresh window, frames begin to overlap, which you experience as smearing or ghosting. All in all, the higher your refresh rate, the more the response time actually matters.

Response time and refresh rate go hand in hand

When you're buying a high refresh rate monitor, you don't just expect smoothness but also better motion clarity during fast scenes. For the latter, you want your monitor's response time to keep up with its refresh rate. If not, you'll end up with smoother animation that still looks blurry. As a competitive gamer, that's the last thing I want after I splurge hundreds of dollars on a gaming monitor hoping to track enemies better. That's why chasing higher refresh rates alone is never enough. You'll need equally fast response times for motion to actually look crisp, which is why I'll always choose OLED monitors over LCDs.
