Yes—an RTX 4070 can output a 240Hz signal, including at 1440p. Whether it can actually produce close to 240 frames per second depends on the game, resolution, graphics settings, CPU, and use of DLSS. It is an excellent match for 1080p esports and a strong, flexible match for 1440p 240Hz gaming—but it will not sustain 240 FPS in demanding AAA games at native Ultra settings.
Refresh rate is not the same as frame rate
A monitor’s refresh rate is how many times it can update its image each second. A game’s frame rate is how many frames the CPU and GPU render each second.
A 240Hz monitor can refresh up to 240 times per second, but it does not require the RTX 4070 to render 240 FPS. If a game runs at 120 FPS, the monitor still works normally; it simply will not receive 240 unique rendered frames every second. G-SYNC Compatible, FreeSync, and other variable-refresh-rate technologies help synchronize the display with fluctuating frame rates.
The important distinction is:
- Display capability: whether the GPU can send a 240Hz signal.
- Rendering capability: whether the game can produce roughly 240 FPS.
- Latency and frame pacing: whether those frames arrive consistently and respond quickly to input.
NVIDIA lists the RTX 4070 with HDMI 2.1a and three DisplayPort 1.4a outputs, with support for up to 4K at 240Hz using DSC under the specified connection and display conditions. That makes 1080p and 1440p 240Hz output well within its technical display range. NVIDIA’s specifications do not, however, promise 240 FPS in games.

RTX 4070 at 1080p and 240Hz
At 1080p, the RTX 4070 is often more than powerful enough for 240 FPS in competitive games when using low or medium settings. Esports titles are generally much easier to render than modern cinematic games, making 240Hz genuinely useful for players who prioritize motion clarity and low input latency.
The limitation at this resolution is often the CPU rather than the GPU. With a fast RTX 4070, lowering visual settings may leave the graphics card underused while the processor, game engine, memory latency, or background software limits frame rate.
A 1080p 240Hz monitor is the focused choice for competitive players who value maximum FPS over image sharpness. For a mixed-use RTX 4070 system, though, 1080p may leave considerable GPU capability unused, and 1440p usually offers a better balance.

| Game type | 240 FPS at 1440p? | Typical approach |
|---|---|---|

As a broad benchmark reference, TechRadar reported an approximately 99 FPS overall average at 1440p in its RTX 4070 test suite, with a 73 FPS average minimum. That is an aggregate result across tested games—not a prediction for every title—and it illustrates why a demanding AAA game should not be expected to run at 240 FPS simply because the monitor supports 240Hz. See the full TechRadar test results.
NVIDIA’s own positioning emphasizes 1440p gaming and reports 100-plus FPS in selected demanding games using DLSS 3. Those figures should not be read as native 1440p Ultra performance at 240 FPS. NVIDIA’s launch announcement explains the tested DLSS 3 context.
What about 4K at 240Hz?
The RTX 4070 can technically drive a 4K 240Hz display through supported HDMI 2.1a or DisplayPort 1.4a modes with DSC. NVIDIA describes DSC as visually lossless compression designed to enable higher resolutions and refresh rates. NVIDIA’s DSC guidance details the relevant compatibility.
That is a signal and bandwidth capability, not a gaming-performance claim. Native 4K at 240 FPS is generally outside the RTX 4070’s realistic target in demanding modern games. If image detail and AAA gaming matter more than extreme competitive refresh rates, a 4K 144Hz or 165Hz monitor is a more appropriate pairing.

How DLSS and Frame Generation change the answer
DLSS Super Resolution renders internally at a lower resolution and uses AI reconstruction to produce the output image. At 1440p, it can substantially increase FPS, although the result varies by game, quality mode, and bottleneck.
Frame Generation creates additional AI-generated frames between conventionally rendered frames. This can make motion appear much smoother and raise the displayed frame rate, but generated FPS is not equivalent to 240 frames rendered directly by the game engine.
For competitive shooters, prioritize conventionally rendered FPS, stable frame times, and responsiveness. Frame Generation may be useful in supported single-player games, particularly with NVIDIA Reflex, which NVIDIA pairs with DLSS 3 to address system responsiveness. A higher displayed FPS number alone does not guarantee lower input latency.

1000 ÷ 240 = 4.17 ms per frame
That tight frame budget exposes CPU and engine limitations that may be invisible at 60 or 144 FPS. CPU model and architecture, single-thread performance, memory speed and latency, game-engine efficiency, background applications, and the game’s own workload all matter.
If reducing graphics settings barely increases FPS, the system may be CPU-limited. In that situation, replacing the monitor or increasing GPU settings will not solve the limitation; a faster CPU, better memory configuration, cleaner background workload, or game-specific optimization may help more. Desktop RTX 4070 cards also differ in cooling and factory power limits, while laptop RTX 4070 implementations can vary substantially and should not be treated as equivalent to the desktop card.
Connection and Windows setup
- Connect the monitor directly to the RTX 4070, not the motherboard’s video output.
- Use the monitor input and cable specified for its 240Hz mode. For 1440p, this may require DisplayPort 1.4 with DSC or HDMI 2.1, depending on the model.
- In Windows, open Settings → System → Display → Advanced display, select the monitor, and choose 240Hz.
- In the monitor’s on-screen menu, enable any required DisplayPort high-bandwidth mode, HDMI 2.1 mode, DSC, Adaptive Sync, or VRR option.
- Open NVIDIA Control Panel → Display → Change resolution, select the monitor’s native PC resolution, and choose 240Hz.
- Where supported, configure VRR through NVIDIA Control Panel → Display → Set up G-SYNC.
- Check the game’s own refresh-rate and FPS settings, then verify actual performance with its built-in counter or a trusted overlay.
If 240Hz is unavailable, try another certified cable and GPU output, check the monitor’s input-specific limits, enable DSC or HDMI 2.1 mode, and update the graphics driver and monitor firmware. Some displays advertise 240Hz but provide it only through one particular port or bandwidth setting.

If a game regularly exceeds 240 FPS, capping it at 240 can reduce unnecessary GPU usage, heat, and power consumption. With VRR enabled, some players cap slightly below the monitor’s maximum refresh rate to stay within the VRR range, while others prefer an uncapped rate for the lowest possible instantaneous latency.
Best Value

There is no universal best cap. The right setting depends on the monitor’s VRR behavior, driver settings, game engine, and whether you prefer maximum responsiveness or steadier frame pacing. A stable 180 FPS can feel better than an erratic 240 FPS with poor 1% lows.
Choosing the monitor matters as much as choosing 240Hz
A “240Hz” label does not automatically mean excellent motion performance. Check independent measurements of response times across refresh rates, overshoot or inverse ghosting, input lag, VRR behavior, and motion clarity rather than relying only on an advertised “0.03ms” figure.
A 1440p 240Hz OLED can be a particularly strong premium match for an RTX 4070. For example, LG lists the 27GS93QE-B as a 27-inch 1440p OLED with 240Hz refresh, advertised 0.03ms response time, G-SYNC Compatibility, and FreeSync Premium Pro. LG’s 27GX704A-B is another 27-inch 1440p 240Hz OLED example; LG notes that its maximum refresh rate requires a graphics card and connection supporting DisplayPort 1.4 or HDMI 2.1.
OLED buyers should also weigh contrast and motion response against brightness, reflections, text rendering, subpixel layout, burn-in precautions, and warranty coverage. IPS panels generally remain attractive for value, bright-room use, and buyers who prefer to avoid OLED-specific trade-offs. The best choice is determined by panel behavior and features—not the refresh-rate number alone.
Is a 240Hz monitor worth buying with an RTX 4070?
Choose 1440p 240Hz if you are:
- A competitive player of games such as Counter-Strike, Valorant, Overwatch, Rocket League, Rainbow Six Siege, or Fortnite.
- Using a reasonably modern, fast CPU.
- Comfortable tuning settings to prioritize frame rate.
- Looking for both sharp 1440p image quality and high-refresh headroom.
- Playing a mix of esports, older games, and demanding releases.
Choose 1440p 165–180Hz instead if you are:
- Primarily playing visually demanding AAA games.
- Using an older or entry-level CPU.
- Price-sensitive and unlikely to notice the difference between 165Hz and 240Hz.
- Better served by spending the budget on HDR, panel quality, resolution, or a faster GPU.
Choose 1080p 240Hz if you are:
- Focused overwhelmingly on competitive gaming.
- Prioritizing maximum FPS and visibility over pixel density.
- Using a strong CPU and a relatively small display or sitting close to the screen.
Choose 4K 144–165Hz if you are:
- Focused on image detail, productivity, media, and single-player games.
- Not expecting the RTX 4070 to approach 240 FPS in demanding titles.
Final verdict
| Use case | Verdict |
|---|---|
| 1080p esports | Excellent fit; 240 FPS is often achievable with competitive settings. |
| 1440p esports | Strong fit, provided the CPU and game can sustain the required frame rate. |
| 1440p mixed gaming | Good fit; 240Hz provides headroom, but not every game will reach 240 FPS. |
| 1440p AAA Ultra | Useful monitor headroom, not a sustained 240 FPS target. |
| 4K AAA | Prefer 144–165Hz or a faster GPU rather than expecting native 4K 240 FPS. |
The RTX 4070 absolutely can handle a 240Hz monitor as a display. It can also make excellent use of one in competitive games, especially at 1080p and tuned 1440p. For mostly cinematic AAA gaming, a quality 1440p 165–180Hz or 4K 144–165Hz display may deliver better value than paying extra for refresh headroom the GPU will rarely fill.
