The debate over high refresh rates in gaming has intensified as 120Hz displays become more accessible. Gamers, hardware reviewers, and competitive players all have strong opinions—some swear by the fluidity of 120Hz, while others argue that the difference is negligible. But what does the science say? And more importantly, will upgrading to a 120Hz monitor improve your gaming experience, or is it just a marketing gimmick?
This in-depth guide will explore:
- The technical aspects of refresh rates and how they affect gameplay
- Real-world comparisons between 60Hz and 120Hz in different gaming scenarios
- Hardware requirements for running games smoothly at 120Hz
- Whether console gamers benefit from 120Hz support
- Common myths and misconceptions about high refresh rates
- Expert opinions and performance benchmarks
By the end, you’ll have a clear understanding of whether a 120Hz display is worth the investment for your gaming setup.
What Is Refresh Rate, and How Does It Impact Gaming?
Understanding Refresh Rate: The Basics
Refresh rate, measured in Hertz (Hz), refers to how many times per second a display updates the image on the screen. A 60Hz monitor refreshes 60 times per second, while a 120Hz monitor does so 120 times.
Why Does This Matter?
- Smoother Motion: Higher refresh rates reduce motion blur, making fast-paced action appear clearer.
- Lower Input Lag: The delay between your input (mouse click, controller movement) and the on-screen response decreases.
- Reduced Screen Tearing: When the game’s frame rate doesn’t match the monitor’s refresh rate, screen tearing occurs. Higher refresh rates minimize this effect.
How Refresh Rate Affects Different Game Genres
Not all games benefit equally from a higher refresh rate. Here’s how different genres are impacted:
1. First-Person Shooters (FPS) – Call of Duty, Valorant, CS:GO
- Advantage: Faster target tracking, smoother recoil control, and improved reaction times.
- Pro Player Insight: Many esports athletes use 240Hz or even 360Hz monitors because every millisecond counts.
2. Racing Games – Forza Horizon, Gran Turismo
- Advantage: Smoother camera movements and better peripheral vision at high speeds.
- Real-World Test: Players report better lap times due to improved precision in cornering.
3. Fighting Games – Street Fighter, Mortal Kombat
- Advantage: More fluid animations and tighter input response for combos.
- Drawback: Some fighting games are locked at 60FPS, negating the benefit of 120Hz.
4. Open-World RPGs – Elden Ring, The Witcher 3
- Advantage: Smoother camera panning and more immersive exploration.
- Drawback: Less critical than in competitive games, but still noticeable.
120Hz vs. 60Hz: Side-by-Side Comparison
Visual Smoothness and Motion Clarity
- 60Hz: Fast movements can appear blurry or stuttery.
- 120Hz: Motion is significantly smoother, especially in fast-paced games.
Example Test (Using CS:GO):
- At 60Hz, quick flicks feel slightly delayed.
- At 120Hz, tracking enemies during rapid turns is noticeably easier.
Input Lag Reduction
- 60Hz: Input lag averages around 16.67ms per frame.
- 120Hz: Input lag drops to ~8.33ms, making controls feel more responsive.
Competitive Impact:
- A study by NVIDIA found that players using 144Hz monitors had a 5-10% higher accuracy rate in aiming tests compared to 60Hz users.
Screen Tearing and Stuttering
- 60Hz with V-Sync: Reduces tearing but adds input lag.
- 120Hz with G-Sync/FreeSync: Nearly eliminates tearing without significant lag.
Does 120Hz Matter for Console Gaming?
PS5 and Xbox Series X: 120Hz Support
Both next-gen consoles support 120Hz, but with caveats:
- Not All Games Support It: Only select titles (Fortnite, Dirt 5, Ori and the Will of the Wisps) offer 120Hz modes.
- Resolution Trade-Offs: Many games drop to 1080p or 1440p to maintain 120FPS.
Do You Need a 120Hz TV or Monitor for Consoles?
- HDMI 2.1 Requirement: For 4K@120Hz, you need an HDMI 2.1-compatible display.
- Budget Options: Many 1080p/1440p 120Hz monitors work well for console gaming.
Real-World Experience:
- Players report that shooters like Call of Duty: Warzone feel much smoother at 120Hz.
- Single-player games (Spider-Man: Miles Morales) still look great at 60Hz.
PC Gaming at 120Hz: Hardware Requirements
Minimum Specs for 120Hz Gaming
| Resolution | GPU Requirement | CPU Requirement | RAM Needed |
|---|---|---|---|
| 1080p | RTX 3060 / RX 6600 XT | Ryzen 5 5600X / i5-12400F | 16GB DDR4 |
| 1440p | RTX 3070 / RX 6800 | Ryzen 7 5800X / i7-12700K | 16GB DDR4 |
| 4K | RTX 4080 / RX 7900 XTX | Ryzen 9 7950X / i9-13900K | 32GB DDR5 |
Optimizing Settings for 120FPS
- Graphics Presets: Lower shadows, anti-aliasing, and post-processing for higher FPS.
- DLSS/FSR: Use AI upscaling to boost performance without major visual loss.
Is 120Hz Worth It for Casual Gamers
If you mostly play:
- Story-driven games (Red Dead Redemption 2, God of War): 60Hz is sufficient.
- Competitive or fast-paced games (Apex Legends, Rocket League): 120Hz is a game-changer.
Common Myths About 120Hz Gaming
Myth 1: “The Human Eye Can’t See Beyond 60Hz”
- Fact: Multiple studies confirm that trained individuals can distinguish up to 240Hz.
Myth 2: “120Hz Drains Battery Life on Laptops”
- Fact: While it does use more power, most gaming laptops allow dynamic refresh rate switching.
Myth 3: “You Need a $1,000 Monitor for 120Hz”
- Fact: Budget options like the AOC 24G2 deliver excellent 120Hz performance under $200.
FAQ: 120Hz Gaming Explained
Q: Can I notice 120Hz if my game runs at 60FPS?
A: No, your FPS must match the refresh rate. A 60FPS game on a 120Hz monitor will look the same as on 60Hz.
Q: Does 120Hz reduce eye strain?
A: Some users report less fatigue due to smoother motion, but blue light filters and proper brightness settings matter more.
Q: Is 120Hz better than 4K for gaming?
A: For competitive play, yes. For cinematic visuals, 4K may be preferable.
Q: Do all games support 120Hz?
A: No, check individual game settings. Some require manual FPS unlocks.
Final Verdict: Should You Upgrade to 120Hz?
- Competitive Gamers: Essential for faster reactions.
- Console Players: Worth it if your display and games support it.
- Casual Gamers: Nice to have, but not critical.
Recommendation: If you play fast-paced or competitive games, a 120Hz monitor is a worthwhile investment. For single-player or cinematic experiences, 60Hz is still great.
