A lot of budget and mid-range monitors sit right at 75Hz, just enough above the old 60Hz standard to get advertised as “smoother,” while 120Hz has become the baseline expected on modern TVs and higher-end monitors alike. The gap between the two is bigger than the numbers alone suggest.
Breaking Down the Frame Time Gap
Refresh rate differences matter most in terms of how much time passes between each new frame, not just the raw Hz number.
- 75Hz produces a new frame roughly every 13.3 milliseconds
- 120Hz produces a new frame roughly every 8.3 milliseconds
- That’s a 5 millisecond difference per frame, a meaningfully larger jump than 60Hz to 75Hz, though smaller than 60Hz to 144Hz
Side-by-Side Comparison
| Category | 75Hz | 120Hz |
|---|---|---|
| Frame time | ~13.3ms | ~8.3ms |
| Motion smoothness | Mild improvement over 60Hz | Clearly smoother, closer to 144Hz territory |
| Common on | Budget monitors, some office displays | Modern TVs, mid-to-high-end monitors, current-gen consoles |
| GPU/console demand | Modest | Higher, needs stronger hardware to sustain |
| Best for | Casual use, light gaming, budget upgrades | Console and PC gaming, general responsiveness |
| Console relevance | Rarely a target frame rate for games | Common target for PS5/Xbox Series X performance modes |
How Much Smoother Is 120Hz, Really
Noticeably smoother, and it’s a bigger jump than people expect when only looking at the Hz numbers on paper. Since frame time savings don’t scale linearly with Hz, the difference between 75Hz and 120Hz ends up closer in feel to the 60Hz-to-144Hz territory than to the mild 60Hz-to-75Hz step.
Worth Knowing: 120Hz has become a meaningful target on consoles specifically because many PS5 and Xbox Series X titles offer a 120fps performance mode. If you’re buying a TV or monitor mainly for console gaming, 120Hz support is a far more relevant spec than it was even a few years ago.
What You Need to Actually Reach 120fps
Getting the full benefit of a 120Hz display requires a few things to line up:
- A GPU or console capable of sustaining frame rates near 120fps in your games of choice
- HDMI 2.1 or DisplayPort with sufficient bandwidth to carry a 120Hz signal at your chosen resolution
- The display and source device both set to allow 120Hz output, since some TVs require enabling a specific game or HDMI mode
Without hitting close to 120fps consistently, a 120Hz panel showing 75-80fps content won’t feel dramatically different from a well-performing 75Hz display.
Is Upgrading From 75Hz to 120Hz Worth It
Based on how this comparison plays out across gaming and general use, the practical take is that this is a genuinely worthwhile upgrade tier, more impactful than most people assume from the numbers alone.
- Worth it for console gamers whose games support 120fps performance modes, since the difference is easy to feel during fast-paced action
- Worth it for PC gamers with a GPU that can consistently push past 100fps in their games
- Less critical if your hardware realistically caps out around 75-90fps anyway, in which case a 120Hz panel adds cost without much added benefit
RTINGS’ refresh rate testing notes that motion clarity improvements continue meaningfully up through this range, unlike the smaller gains seen at the very top end of the refresh rate scale.
Frequently Asked Questions
1. Is 120Hz a big jump from 75Hz, or a small one?
It’s a meaningful jump, saving about 5 milliseconds per frame, noticeably more than the smaller gap between 60Hz and 75Hz.
2. Do PS5 and Xbox Series X support 120Hz?
Yes, many games offer a 120fps performance mode, making 120Hz support a relevant spec for console-focused buyers with a compatible TV or monitor.
3. Can I use 120Hz without a powerful GPU?
You can, but you’ll only see the full benefit in games or tasks that can actually run near 120fps; otherwise the panel is capped by your hardware’s real frame output.
4. Is 75Hz still worth buying in 2026?
It’s fine for budget builds, office work, or casual use, but for gaming specifically, 120Hz offers a clearly noticeable step up for a moderate price difference.
Final Take
75Hz to 120Hz delivers a bigger real-world improvement than the raw numbers suggest, especially for console gamers taking advantage of 120fps performance modes. It’s one of the more underrated refresh rate upgrade tiers available today.
For related comparisons, see 75Hz vs 144Hz and 60Hz vs 75Hz.
- 120Hz saves about 5 milliseconds per frame compared to 75Hz, a bigger real-world gap than the Hz numbers alone suggest.
- 120Hz has become especially relevant for console gaming due to PS5 and Xbox Series X 120fps performance modes.
- Reaching the full benefit requires HDMI 2.1/DisplayPort bandwidth and hardware capable of sustaining near 120fps.
- This upgrade tier is considered more impactful than the smaller 60Hz to 75Hz step.
