Why refresh rate really matters

If you’ve seen two screens side by side, one running at 60Hz and another at 144Hz, you know the difference is striking. Now imagine comparing 144Hz to 240Hz: the conversation gets more subtle, but still decisive depending on the game and who’s sitting in the chair.

Refresh rate measures how many times per second the monitor redraws the image. A 240Hz monitor refreshes the frame 240 times per second, compared to 144 on a 144Hz panel. In practice, this means smoother motion, less ghosting (that blurry trail that persists behind moving objects) and, in competitive games, a potentially smaller reaction window between what happens on the server and what you see on screen.

The short answer: if you play competitive titles like Valorant, CS2 or Apex Legends at a high level and your GPU can consistently deliver more than 144 frames per second, 240Hz makes a measurable difference. For most players, including those who enjoy RPGs, single-player action games, or any title where 144 fps is already the realistic ceiling of your hardware, 144Hz delivers an excellent experience with lower cost and power consumption. The rest of this article details why this is true and how to apply it to your specific case.

Technical comparison: 144Hz vs 240Hz side by side

Values are market estimates in 2026 and vary depending on exchange rate, store and promotions.

What the refresh rate difference means in practice

The jump from 60Hz to 144Hz is the most impactful any gamer will experience: it reduces the time between frames from 16.67 ms to 6.94 ms, a cut of nearly 60%. The jump from 144Hz to 240Hz reduces that interval from 6.94 ms to 4.17 ms, a difference of 2.77 ms.

Two milliseconds seem insignificant, but in first-person shooter games where a gunfight lasts less than 300 ms, that margin has weight. Professional CS2 and Valorant players consistently cite the smoothness of 240Hz monitors as a comfort factor, especially in situations of tracking rapidly moving targets, the so-called tracking. Outside the high-level competitive scenario, the difference is noticeable but rarely decisive.

There’s a critical point many people ignore: your computer needs to deliver the frames the monitor will display. There’s no point in a 240Hz panel if your GPU delivers 90 fps on average in the game you play the most. In that case, you’ll be paying for the potential of a screen that will never operate at the limit for which it was designed. Before any purchase, check the benchmarks of your GPU in the main title you play, with the resolution you intend to use.

Panel types: where screen technology comes into play

Refresh rate doesn’t exist in a vacuum. Panel type directly influences image quality and motion behavior, and here 144Hz and 240Hz divide into distinct market categories.

TN (Twisted Nematic) Panels

The TN panel is the oldest and still the fastest in raw response time. 240Hz TN monitors reach 0.5 ms GtG (Gray-to-Gray, the time it takes a pixel to change from one shade of gray to another). The problem is inferior image quality: poor viewing angles, less vibrant colors and lower contrast. In 2026, most buyers avoid TN unless the sole objective is purely competitive performance at the lowest cost possible.

IPS and Fast IPS Panels

The IPS panel (In-Plane Switching) balances accurate colors, good viewing angles and acceptable response time. The Fast IPS variant, adopted by manufacturers like LG and Asus in high-performance lines, reduces response time to 1 ms GtG according to technical specifications, making it suitable for 240Hz without sacrificing image quality. It’s the dominant panel in the premium gaming segment today.

VA Panels

The VA (Vertical Alignment) delivers the highest native contrast among the three types, which favors games with dark scenes. The historical weak point is smearing, a type of ghosting more noticeable in fast motion. 240Hz VA monitors exist, but always check the real response time reviews before buying: the manufacturer’s specification doesn’t always match behavior in high-contrast scenes.

Resolution and GPU: the triangle you need to close

Choosing between 144Hz and 240Hz without considering resolution and video card is like buying racing tires for a family car. All three variables need to be aligned.

At 1080p, it’s easier to push 240 fps with mid-range GPUs. A card like the RTX 4060 or RX 7600, available in Brazil in ranges that vary greatly depending on exchange rates, can reach and maintain 240 fps in graphically less demanding competitive titles. Already in 1440p with 240Hz, you’ll need more robust hardware: high-end GPUs like RTX 4070 Super or RX 7800 XT are the realistic starting point to maintain refresh rate in games like Overwatch 2 or Fortnite on high settings.

The adaptive sync technology alleviates this problem. AMD’s FreeSync and Nvidia’s G-Sync Compatible synchronize the monitor’s refresh rate with the number of frames the GPU delivers in real time, eliminating screen tearing and reducing stuttering even when you don’t reach the panel’s maximum limit. Check the monitor’s technical sheet to see if it supports the technology compatible with your GPU. If you’re playing with an Nvidia card on a FreeSync monitor, check if it has G-Sync Compatible certification to ensure full compatibility.

Brazilian context: imports, Anatel and warranty

Buying an imported monitor in Brazil carries real risks. Monitors without Anatel approval can be held at customs, and you have no local warranty, depending solely on the seller for any shipping issues or factory defects.

The brands with consolidated presence in Brazil in 2026 include LG, Samsung, AOC, Asus (ROG and TUF Gaming lines), MSI and Acer (Predator and Nitro lines). All these manufacturers have official distributors with national technical support and at least 12 months warranty. Models imported via international order may work out cheaper on paper, but the risk of customs problems, lack of warranty and incompatible voltage (some monitors don’t accept 127V without an adapter) should factor into your account.

In terms of availability, 1080p 144Hz monitors are accessible in practically all major retail chains. 240Hz IPS panel models with G-Sync certification still have lower availability outside major centers, being easier to find in specialized online stores like Kabum, Pichau and Terabyte.

Frequently asked questions about 144Hz and 240Hz monitors

Is it worth paying more for 240Hz if my PC doesn’t deliver 240 fps?

Not in most cases. If your GPU delivers between 100 and 160 fps on your main game, a 144Hz monitor with good adaptive sync will extract everything your hardware has to offer. The 240Hz monitor will only shine when you can feed it with the number of frames for which it was designed consistently.

What’s the difference between response time and refresh rate?

They’re different things. Refresh rate (Hz) is how many times the monitor redraws the image per second. Response time (ms) is how long it takes a pixel to change color. Both affect motion clarity, but in different ways: high rate reduces the window between frames, low response time reduces ghosting within each frame.

240Hz 1080p or 144Hz 1440p monitor for competitive games?

It depends on the game and your GPU. For CS2 and Valorant at high competitive level, 240Hz 1080p is the dominant choice among professional players because it makes it easier to reach maximum refresh rate. For those who play varied titles and also appreciate visual quality, 144Hz 1440p delivers a significantly sharper image without requiring a top-tier GPU.

IPS or TN for 240Hz: which to choose in 2026?

IPS, in the vast majority of cases. The Fast IPS panels of 2025 and 2026 reach 1 ms response according to official specifications, making the practical difference compared to TN minimal for most gamers. In contrast, IPS color quality and viewing angles are visibly superior for any use outside of gaming.

Which to choose: recommendation by profile and budget

The deciding criterion is not the number on the box, but the actual use you’ll make of it.

If you play fast-paced competitive titles (CS2, Valorant, Apex), have a GPU capable of consistently delivering over 180 fps and are willing to invest between R$ 1,800 and R$ 3,500: 240Hz is the way to go. Look for models with Fast IPS panel, 1 ms response time on the technical sheet and FreeSync Premium or G-Sync Compatible certification. Check national warranty availability before closing your purchase.

If you have a mid-range GPU, play varied titles including single-player games, or are building your first gaming setup with a budget between R$ 900 and R$ 1,800: 144Hz 1080p or 144Hz 1440p are smarter choices. The smoothness difference compared to 240Hz will be imperceptible in your use case, and the money saved can go toward a faster SSD or more RAM, upgrades with broader impact.

If you’re undecided between the two scenarios: go to a physical store, if possible, and watch both screens moving with the same content. Individual perception varies, and what seems obvious in a review might be indifferent to you in practice.

The right decision is the one that closes the triangle of monitor, GPU and game without leaving any of the three points idle. More than the number of hertz, what matters is the coherence of the entire setup.
