Trying to decide between a fast response time and high refresh rate for a gaming monitor? Which one actually impacts gameplay more, especially in fast-paced titles? I've heard 1ms is the gold standard for response time, but does 240Hz make a bigger difference than say, 165Hz? Looking for insights from people who've dealt with both.
Response time vs. refresh rate: which really matters?

Here's a real case: a couple of months ago, I built a PC for a friend who's a huge CS2 and Valorant fan. He had a 1080p 240Hz monitor with a 0.5ms response time, but when he switched to 165Hz, he didn't feel any difference in smoothness—only some motion trails behind objects remained. We tried a 144Hz 1ms panel (IPS, not TN), and everything became smoother—colors were nicer, and there were no motion trails. So, 240Hz is great if your hardware can handle it, but otherwise, 165Hz with a good response time is better than the other way around. After switching monitors, my friend's FPS dropped by 10-15%, but subjectively, the gameplay felt much more comfortable. So the takeaway is: if you're not hitting 500+ FPS, a 165-240Hz IPS with a 1ms response time is better than a 144Hz with 0.5ms.
Man, this is a classic dilemma everyone goes through when upgrading their setup. I remember when I swapped from a 144Hz 4ms monitor to a 240Hz 0.5ms beast—it was like night and day in shooters like CS2. At first, I thought the response time made more of a difference, but then I realized that higher Hz is way more noticeable in fast-paced games. Especially in games where you need to track fast movements, like Valorant or Quake champions, the smoother transitions between frames from 240Hz just feel so much more responsive, even if the actual latency difference between 0.5ms and 1ms isn’t always *that* big in real terms.
Still, don’t sleep on response time though—especially if you’re playing competitive games where ghosting or smearing can mess up your shots. I had my fair share of flicks failing because my old screen couldn’t keep up with 144Hz without some nasty blurring. So yeah, if you’re going 240Hz, make sure your response time is at least decent (0.5ms–1ms), otherwise you’re kind of wasting all that refresh rate power. It’s the combo that works best—high Hz for smoothness, low response time for clarity.
