Refresh rate in games: what actually changes from 144Hz to 240Hz in practice

The difference between a 144Hz monitor and a 240Hz monitor is more than just a bigger number on the box. Refresh rate, measured in hertz (Hz), indicates how many times per second the image on screen is redrawn. At 144Hz, this happens 144 times per second. At 240Hz, it’s 240 times. The interval between each frame gets smaller, movement looks smoother, and in theory, you react faster to what you see.

But here’s the central question: is this difference noticeable for you, on your setup, in the games you play? The honest answer is: it depends a lot. For most Brazilian gamers, a well-calibrated 144Hz monitor delivers an excellent experience. The jump from 60Hz to 144Hz is transformative. The jump from 144Hz to 240Hz is more refined, more situational, and requires the rest of your hardware to keep up.

This comparison was made to help you make this decision without spending more than necessary, or without saving where you shouldn’t.

What the difference in Hz actually changes in gameplay

The concept of input lag is central here. Input lag is the time that passes between you pressing a button and the result appearing on screen. A higher refresh rate reduces the window of time the monitor “waits” to show the next frame. At 144Hz, that window is approximately 6.9 milliseconds. At 240Hz, it drops to about 4.2ms.

It seems like little, and it is. For slower-paced games like RPGs, strategy, or adventure, this difference is completely imperceptible. In competitive shooters (like CS2, Valorant, or Apex Legends) and fighting games, where decisions happen in fractions of a second, this gain can be real. Players competing at high levels, especially in tournaments, tend to notice and value this difference.

The problem is that seeing 240 frames per second requires your GPU (graphics card) to also deliver 240 FPS (frames per second) consistently. If your computer runs the game at 120 FPS, you’re using a 240Hz monitor as if it were 120Hz. The hardware needs to be aligned with the display.

When 144Hz is more than enough

For most gamers in Brazil, 144Hz is the ideal cost-benefit sweet spot in 2026. 144Hz monitors in 1440p resolution (also called QHD, or 2K, with 2560×1440 pixels) have come down in price and offer visibly sharper image than 1080p without requiring a cutting-edge GPU.

If you play titles like God of War, Elden Ring, Hogwarts Legacy, or any open-world game, resolution and panel quality (IPS or OLED) will impact your experience much more than going from 144Hz to 240Hz. In these games, achieving a constant 144 FPS already requires a robust GPU like an RTX 4070 or AMD equivalent.

Another important point: modern 144Hz monitors with Fast IPS or IPS Black panels deliver vibrant colors, wide viewing angles, and very good response times according to manufacturer spec sheets. Image quality has improved significantly in this price range over the past two years.

When 240Hz makes a real difference

The clearest use case for 240Hz is the competitive first-person shooter player who already has a GPU capable of delivering high FPS consistently. If you play Valorant or CS2 on low settings to maximize FPS and already exceed 200 frames per second, the 240Hz monitor will take advantage of that performance.

240Hz monitors also come with OLED panels in 2025 and 2026, combining high refresh rate with exceptional image quality, response time near zero (per manufacturer specs), and infinite contrast. Models like the 27-inch LG UltraGear OLED and Asus ROG Swift OLED are examples in this range. These monitors arrive in Brazil above R$ 4,000 and, in some cases, around R$ 6,000 or more, depending on exchange rate and importer.

For those wanting the best of both worlds, image quality and speed, a 240Hz OLED is the top of the category today. But the price charges heavily for it.

Resolution enters the equation: 1080p, 1440p, or 4K?

A 240Hz monitor at 1080p is the classic competitive gamer setup wanting high FPS above all else. The GPU works less to render images at lower resolution, making it easier to achieve high frame rates. It’s the choice of those who play CS2 or Valorant seriously.

A 240Hz monitor at 1440p demands more from the GPU but delivers much better image. It’s a balance that makes sense for those with a high-performance graphics card like an RTX 4080 or RX 7900 XTX, and want to compete without sacrificing sharpness.

4K at 240Hz is still absolute top territory, with prices above R$ 8,000 in most cases available in Brazil. For this level, always check the spec sheet regarding DisplayPort 2.1 requirement, which isn’t present on all GPUs yet. If your monitor requires DisplayPort 2.1 and your GPU only has 1.4, you may not be able to get 240Hz at 4K with the right connection. Confirm compatibility before buying.

Brazilian context: imports, warranty, and availability

Here in Brazil, high-performance monitors arrive two ways: official import with invoice and national warranty (typically 1 year), or parallel import, which may cost less but without local support and no valid warranty here.

Monitors with Anatel approval guarantee the product met Brazilian regulatory requirements. For monitors, the requirement relates mainly to power supplies and electromagnetic emissions. Products sold by official distributors of brands like LG, Samsung, Asus, and AOC tend to come with this approval. Shopping at stores like Kabum, Pichau, Amazon Brazil, and Terabyte Shop, you’ll find options with invoice and national warranty more easily.

Importing on your own (via American or Asian sites) can save 20% to 40% on some models, but you assume customs risks, possible import tax charges, and lack of local technical support. For equipment that may cost R$ 3,000 or more, it’s worth thinking carefully about this choice.

Frequently asked questions about 144Hz and 240Hz monitors

Can I feel the difference between 144Hz and 240Hz without being a professional gamer?

Most people notice some extra smoothness when moving the cursor or during fast action scenes, but under normal gaming conditions the difference is much more subtle than the jump from 60Hz to 144Hz. Casual players or those playing less competitive titles will hardly notice in practice. It also depends on whether your computer delivers the necessary FPS to feed the monitor.

Does my GPU need to deliver exactly 240 FPS for the monitor to be worthwhile?

Not exactly, but the closer to 240 FPS consistently, the more you’ll leverage the monitor. Technologies like G-Sync (Nvidia) and FreeSync (AMD) synchronize the monitor’s refresh rate with the GPU’s FPS within a frequency range, which reduces screen tearing (when two different frames appear at once) and keeps the image stable even below 240 FPS. Check if the monitor and GPU are compatible with the sync technology.

Does a 240Hz monitor work for watching movies and series?

Yes, no problem. The monitor will display content at 24Hz, 30Hz, or 60Hz normally. Some models have frame interpolation to smooth playback, but most users prefer to disable this feature, which can create the so-called “soap opera effect” on movies. The video experience on a good 240Hz IPS or OLED panel is typically very good, regardless of the source’s refresh rate.

Is it worth waiting for new models or buying now?

In 2026, 240Hz OLED monitors are already well-established in the market. New models with DisplayPort 2.1 and even higher resolutions will emerge, but the current lineup already serves well. If you need a monitor now and have the budget, there’s no reason to wait. If you’re in doubt, always check the spec sheets on manufacturers’ official sites before finalizing your purchase.

Which to choose: 144Hz or 240Hz?

The right choice depends on three factors: what you play, what your current hardware is, and how much you can spend.

If you play a variety of games, including adventure, RPG, sports, or open-world titles, a 144Hz monitor at 1440p with an IPS panel is probably the best cost-benefit decision you’ll make. The resolution and image quality improvement will impact your daily experience much more than 96 extra Hz of refresh rate.

If you’re a competitive gamer, especially of shooters where milliseconds matter and your GPU already delivers high FPS consistently, the investment in 240Hz makes sense and has technical justification. In that case, if budget allows, a 240Hz OLED model will combine the best of both worlds.

If your budget is limited, always prioritize refresh rate over resolution. A well-calibrated 1080p at 144Hz is better for gaming than 4K at 60Hz. And if you want to expand your setup gradually, it might also be worth looking at laptops for programming up to R$ 5,000 if your setup is oriented toward creation or work beyond gaming.

In the end, 240Hz is the current top for gaming performance, but 144Hz remains the balance point that most Brazilian gamers will truly leverage, without leaving money on the table buying hardware the rest of your setup can’t feed.
