When buying a new monitor, the refresh rate is one of the most important specifications to consider. This metric determines how many times per second your display updates with a new image. A higher refresh rate translates to smoother motion and less visual blur.
For gaming and fast-paced visual workloads, 120Hz and 240Hz monitors have become common choices to deliver a responsive, high performance experience. But which one is right for you? Let‘s compare 120Hz versus 240Hz refresh rates across critical categories.
What is Refresh Rate?
Before diving into 120Hz versus 240Hz, it‘s helpful to understand exactly what a monitor‘s refresh rate means.
The refresh rate determines how many images (or "frames") a display can show each second. It‘s measured in Hertz (Hz). A 60Hz screen updates 60 times per second, a 120Hz refreshes 120 times per second, and so on.
For gaming and video, a higher refresh rate translates to smoother motion transitions. It reduces motion blur, making fast movement look crisp. Higher refresh displays also decrease input lag, which is the delay between pressing a button and seeing the result on screen.
How Panel Type Impacts Refresh Rate
The monitor panel technology – usually TN, IPS or VA type LCDs – can limit refresh rate capabilities. While marketing materials may claim extremely high advertised refresh rates, real world performance depends on the pixel response times possible with the underlying panel.
TN (twisted nematic) panels offer the fastest response times, making them well suited for high refresh gaming. IPS (in-plane switching) panels provide better colors and viewing angles but slower response. VA (vertical alignment) offers a middle ground. Response time shortcomings on IPS and VA panels can lead to ghosting artifacts at high refresh rates.
That‘s why the most popular Esports gaming monitors utilize TN panel technology to enable minimal motion blur. However, continued panel innovations like OLED and newer IPS variants help address these constraints.
Overview of 120Hz Refresh Rate Monitors
For many years, 60Hz was the standard for monitors. A 120Hz refresh rate delivers major improvements in motion clarity and responsiveness. Instead of just 60 updates per second, a 120Hz panel refreshes twice as often.
Some benefits of 120Hz monitors include:
- Smoother animation, scrolling, and transitions
- Reduced motion blur during fast movement and action sequences
- Decreased input lag for a more responsive feel
- Enhanced gaming visuals and performance
Testing shows 120Hz displays decreasing input lag by an average of 8-10ms compared to 60Hz alternatives. While not a night and day difference alone, combined with the smoother visuals this responsiveness boost enhances most gaming experiences.
The faster refresh and lower latency make 120Hz a popular choice for gaming. It also provides a great experience for watching sports and action movies. Fast-paced titles and films with quick camera cuts see a big boost.
120Hz monitors are widely accessible and affordable today. On average they cost $100-150 more than a standard 60Hz display with similar features. Laptops also now commonly offer 120Hz refresh rate screen options in their lineup.
What is G-Sync and FreeSync?
Monitors with adaptive sync technology like Nvidia G-Sync and AMD FreeSync dynamically match the panel‘s refresh rate to the graphical frame rate output of the system. This prevents screen tearing and minimizes stuttering for smoother gameplay.
For example, if a game‘s performance drops to 100 fps, a G-Sync monitor will automatically shift refresh to 100Hz. V-Sync alternatively caps frame rate to your display‘s fixed refresh capability, often introducing lag or judder during fluctuations.
Utilizing DisplayPort or HDMI connections, G-Sync and FreeSync deliver their best experience when frame rates exceed the minimum refresh threshold. This makes 120Hz well suited to take advantage.
Overview of 240Hz Refresh Rate Monitors
Pushing refresh rates even higher, 240Hz monitors first hit the market around 2017. Top Esports professionals helped drive demand.
Quadrupling the baseline 60Hz speed, 240Hz displays update the image a staggering 240 times per second! This brings incredible improvements to motion clarity and system latency.
In testing, 240Hz monitors can lower input lag by an additional 2-3ms versus 120Hz alternatives. While not a major reduction alone, when paired with four times the refresh rate games feel lightning quick.
Benefits of 240Hz panels include:
- Buttery smooth animation with extremely sharp transitions
- Esports professionals can more easily track fast moving objects like crosshairs and targets
- Near complete elimination of motion blur in action sequences
- Extremely low input lag for ultra responsive controls
240Hz monitors excel for Esports titles where split second reaction times determine success. Fast-paced first person shooters (FPS), racing sims, fighting games, and rhythm games see the biggest boosts. Casual gamers may also appreciate the fluidity in adventure and role playing games.
Currently 240Hz displays cost around $300-500+ more than equivalent 120Hz options. The premium pricing combined with demanding hardware requirements limit wider mainstream adoption for now.
