Hz is how often your display can update. FPS is how many frames your PC, console, or other source produces. They work together, but neither automatically increases the other: a 144 Hz monitor does not create 144 FPS, and a game running at 144 FPS cannot show every frame on a fixed 60 Hz display.
What refresh rate means
Refresh rate is a display specification measured in hertz (Hz). It describes how many times the screen can begin a new image update each second.

| Refresh rate | Maximum updates per second | Time per refresh |
|---|---|---|
| 60 Hz | 60 | 16.67 ms |
| 75 Hz | 75 | 13.33 ms |
| 120 Hz | 120 | 8.33 ms |
| 144 Hz | 144 | 6.94 ms |
| 165 Hz | 165 | 6.06 ms |
| 240 Hz | 240 | 4.17 ms |
| 360 Hz | 360 | 2.78 ms |
The interval is calculated as 1 ÷ refresh rate. A higher refresh rate can make scrolling, cursor movement, animation, and games look smoother because the display has more opportunities to present new information. It does not, however, make the computer render more frames.

What frame rate means
Frame rate is the speed at which the source produces or delivers frames, measured in frames per second (FPS). In a game, the CPU, GPU, game engine, graphics settings, resolution, ray tracing, upscaling, frame generation, background tasks, and thermal limits can all affect FPS.
FPS is not necessarily constant. A game averaging 120 FPS may still stutter if some frames take much longer to render than others. Frame time is often a better description of moment-to-moment smoothness:
- 60 FPS is approximately 16.67 ms per frame.
- 120 FPS is approximately 8.33 ms per frame.
- 144 FPS is approximately 6.94 ms per frame.
- 240 FPS is approximately 4.17 ms per frame.
That is why 1% lows and frame-time graphs matter. A stable 90 FPS can feel smoother than an inconsistent 140 FPS with shader-compilation pauses, CPU stalls, asset-streaming problems, or background activity.

| Situation | Likely result | Useful advice |
|---|---|---|
| FPS equals Hz | A straightforward fixed-rate match, assuming consistent timing | Check frame pacing and synchronization |
| FPS is lower than Hz without VRR | Frames may repeat, creating uneven cadence | Enable VRR if supported |
| FPS is higher than Hz with V-Sync off | Possible tearing and potentially lower latency | Use VRR, a cap, or V-Sync according to your priorities |
| FPS is higher than Hz with V-Sync on | Tearing is reduced, but latency or pacing may increase | Test the result in the games you play |
| FPS fluctuates inside the VRR range | The display can follow the source more smoothly | Confirm the monitor’s actual VRR range |
| FPS falls below the VRR minimum | VRR may disengage or use low-framerate compensation | Check whether the display supports LFC |
When FPS equals refresh rate
For example, 144 FPS on a 144 Hz display is an approximate capacity match. It is not automatically perfect: frame-time variation, pixel response, input latency, and synchronization settings still affect the result.
When FPS is lower than Hz
At 60 FPS on a 144 Hz fixed-refresh monitor, the monitor has more update capacity than the game is supplying. Without variable refresh rate, some frames may be shown more than once and the cadence may be uneven. A 60 FPS game therefore does not look like a 144 FPS game merely because the monitor is rated at 144 Hz.
With VRR, the display can change its refresh timing to follow incoming frames within its supported operating range. A 144 Hz monitor running a game between roughly 100 and 140 FPS can be a very practical smooth-gaming setup if that range is supported.
When FPS is higher than Hz
At 200 FPS on a 144 Hz fixed-refresh monitor, the GPU is producing frames faster than the screen can present them.

With V-Sync disabled, the display can begin scanning a newer frame before finishing the previous one. This produces screen tearing, visible as horizontal breaks in the image. It can also reduce latency because the system is not waiting for the next refresh opportunity.
With V-Sync enabled, presentation is coordinated with the monitor’s refresh schedule, reducing tearing but potentially adding latency or causing stutter when the GPU cannot maintain the target rate. VRR can follow changing FPS within its range, but an FPS cap or synchronization setting may still be needed when the frame rate exceeds that range.
Is 144 Hz the same as 144 FPS?
No. 144 Hz is the display’s maximum update rate; 144 FPS is the source’s frame-production rate. A 144 Hz monitor can display lower frame rates, especially with VRR, and a computer can render 144 FPS even when connected to a 60 Hz screen. On a fixed-refresh display, excess frames may be discarded or cause tearing rather than all being shown cleanly.
Can a 60 FPS game benefit from a 144 Hz monitor?
Yes, but with limits. The monitor can still provide smoother desktop interaction, a shorter refresh interval, and flexibility for games that run above 60 FPS. It may also handle fluctuating rates more cleanly when VRR is enabled.
What it cannot do is turn a 60 FPS game into a 144 FPS experience. If the game remains locked at 60 FPS, the source is still delivering only 60 distinct frames per second.
V-Sync and VRR explained
V-Sync
Vertical synchronization coordinates frame presentation with a fixed refresh schedule. It can reduce tearing, but it does not increase FPS or turn a 60 Hz panel into a high-refresh display. Depending on the game and implementation, it may add latency or produce stutter when FPS falls below the display’s target rate.
Variable refresh rate
VRR allows the display to vary its refresh timing to match the source’s changing frame rate. The important specification is the VRR range, such as 48–144 Hz or 40–240 Hz—not merely whether the box says “VRR.” Below the minimum, the display may leave VRR mode or use low-framerate compensation (LFC), which repeats frames to keep the display operating within its range.

VRR can reduce or eliminate tearing within its supported range, but it is not a universal guarantee. Compatibility depends on the display, GPU or console, input, cable, driver, game mode, and presentation method.

Adaptive-Sync is the standards-based variable-refresh technology associated with DisplayPort. AMD FreeSync is AMD’s display certification and branding ecosystem, with FreeSync, FreeSync Premium, and FreeSync Premium Pro tiers. AMD says its certification covers different requirements, including refresh-rate, low-framerate-compensation, and HDR-related criteria depending on the tier.
NVIDIA G-SYNC includes native G-SYNC displays and G-SYNC Compatible monitors using Adaptive-Sync. NVIDIA provides model-specific information such as VRR range, input type, panel type, and variable-overdrive support. Compatibility should be checked for the exact GPU, monitor, resolution, cable, and input rather than assumed from the logo.
FreeSync is not automatically inferior to G-SYNC, and G-SYNC is not automatically better. Compare the particular monitor’s VRR range, response behavior, input lag, overdrive, HDR, connector support, and GPU compatibility.
Does higher refresh rate reduce input lag?
It can reduce the time between possible display updates. For example, a 240 Hz display has a 4.17 ms refresh interval compared with 6.94 ms at 144 Hz. That can help reduce display-side latency, particularly when the system is producing high FPS.

Rendering time, the game’s frame queue, scanout position, pixel response, input devices, drivers, and display processing also matter. A high-refresh monitor with poor response behavior or excessive processing is not automatically more responsive in practice.
Refresh rate is not response time
| Specification | What it describes |
|---|---|
| Refresh rate | How often the display can begin a new update |
| Frame time | How long the computer takes to produce one frame |
| Pixel response time | How quickly pixels change between states |
| Input latency | Delay between an input or frame and the visible result |
A claimed “1 ms response time” does not mean 1 ms input lag, 1 ms frame time, or a 1,000 Hz refresh rate. Poor pixel transitions can cause ghosting or smearing even on a 240 Hz panel. Overdrive can improve transitions but may introduce bright or dark overshoot.

Refresh rate is not resolution
Refresh rate and resolution are separate choices that often compete for GPU performance and connection bandwidth. A 1080p 240 Hz display is generally easier to drive than a 4K 240 Hz display. A 4K 144 Hz screen may be preferable for image detail, while a 1080p 240 Hz model may suit a competitive player who can sustain very high FPS.
A monitor’s headline maximum may apply only to a particular input, resolution, color depth, compression mode, or overclock setting. Check the manufacturer’s specifications for the exact mode you intend to use.
How to change refresh rate and enable VRR
Windows
- Open Settings.
- Select System, then Display.
- Select the relevant display if multiple screens are connected.
- Open Advanced display.
- Choose the desired refresh rate.
The panel also shows the active resolution and may indicate VRR support. Labels can differ between Windows builds and hardware.
NVIDIA Control Panel
Open NVIDIA Control Panel > Display > Change resolution, select the monitor, and choose the refresh rate. VRR generally also requires the feature to be enabled in the monitor’s on-screen display and in the appropriate NVIDIA driver setting.
AMD Software: Adrenalin Edition
- Enable FreeSync in the monitor’s on-screen display.
- Disable anti-blur or backlight-strobing modes if they conflict with FreeSync.
- Confirm the display connection is configured correctly.
- Open AMD Software: Adrenalin Edition.
- Enable FreeSync globally or for the relevant game profile.
Menu names vary by monitor and driver version. A monitor may not be able to use VRR and motion-blur reduction simultaneously.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Troubleshooting common problems
Windows shows 144 Hz when the monitor is advertised as 165 Hz
Check whether 165 Hz is available only through DisplayPort, whether the monitor requires an on-screen-menu overclock option, and whether the selected resolution or color depth limits the mode. Also check the GPU connection, cable, dock, adapter, KVM, receiver, input mode, and graphics driver. Do not assume that a cable label alone guarantees a particular resolution and refresh rate.
VRR is enabled but tearing remains
- Confirm VRR is enabled both in the monitor and the GPU software.
- Check that the game is using a supported display mode and input.
- Verify the frame rate is inside the monitor’s VRR range.
- Check the correct monitor in a multi-display setup.
- Look for another synchronization setting overriding VRR.
- Test windowed, borderless, and exclusive-fullscreen modes.
- Update the monitor firmware and GPU driver where appropriate.
VRR causes flicker
Brightness fluctuation can occur on some LCD and OLED displays when frame rate changes rapidly or crosses a wide range. Firmware behavior, unstable frame rates, a marginal signal path, and conflicts with anti-blur modes can also contribute. Try a steadier FPS cap, a different VRR mode, updated firmware, or a different connection, while following the monitor’s manual.

The desired refresh rate is missing
Make sure the monitor is connected to the dedicated GPU rather than the motherboard output, select the correct resolution, enable the monitor’s high-bandwidth input mode, and remove restrictive docks or adapters. If the screen goes blank after selecting an unsupported mode, wait for Windows to revert or use another display or input to restore a supported setting.
What refresh rate should you choose?
Choose according to the FPS your system can sustain in the games and resolution you actually use—not its highest brief peak.
- 60–75 Hz: Suitable for office work, general use, basic video playback, older systems, and entry-level gaming.
- 100–165 Hz: A strong general-purpose range for many PC gamers, particularly when the GPU can sustain rates above 60 FPS.
- 240 Hz: More useful to competitive players with systems capable of consistently high FPS. The improvement over 144 or 165 Hz is real but smaller than the move from 60 Hz to 120/144 Hz.
- 360 Hz and above: A specialist esports choice for unusually high frame rates and buyers who value small latency and motion-clarity gains enough to pay for them.
For console gaming, check the exact console, game, TV or monitor, HDMI mode, resolution, and VRR support. A panel’s nominal refresh rate may not be available through every output or game mode. The same caution applies to laptops, whose internal and external displays may use different GPU paths.
What about movies?
Video cadence matters as well as the display’s maximum rate. Film commonly uses 24 FPS. A 120 Hz display is an integer multiple of 24, so it can present that cadence without the 3:2 pulldown pattern commonly associated with 60 Hz playback. This does not mean every 120 Hz display or video setting automatically eliminates all judder, but the relationship is useful for film playback.
Is 240 Hz worth it over 144 Hz?
It depends on your workload. If your games usually run around 70–120 FPS, a good 144 or 165 Hz VRR monitor is generally a better fit than paying for 240 Hz that you rarely use. If you play competitive games at a sustained 200 FPS or higher and value lower update intervals, 240 Hz can make sense.
Before spending more on refresh rate, consider whether the money would provide more benefit through a faster GPU, higher resolution, better HDR, a better panel, lower input lag, or more reliable pixel response.
Monitor buying checklist
- Measure sustained performance: Look at typical FPS, 1% lows, and frame-time consistency in your actual games.
- Choose the resolution: Match image-detail priorities and GPU capability to the target refresh rate.
- Check the VRR range: Confirm the minimum, maximum, and low-framerate-compensation behavior.
- Verify compatibility: Check the GPU or console, input type, cable, resolution, and color mode.
- Check real response behavior: Look for measured transitions, overshoot, and input lag rather than trusting a “1 ms” label.
- Evaluate the panel: Compare viewing angles, contrast, HDR brightness, local dimming, and OLED characteristics.
- Check connection bandwidth: Ensure the desired resolution and refresh rate work on the actual HDMI or DisplayPort input.
- Review ownership terms: Consider warranty, return policy, and OLED burn-in coverage for static desktop use.
The best display is not necessarily the one with the largest Hz number. It is the one whose refresh rate, VRR behavior, response performance, resolution, and connection support fit the way you play.

FPS is the source’s production rate; Hz is the screen’s presentation capacity. For smooth gaming, prioritize a display with a refresh rate your system can use, consistent frame times, a useful VRR range, good pixel response, and the resolution and image quality you want. A high-refresh monitor can be worthwhile even when you do not always reach its maximum, but it cannot manufacture frames your PC or console does not render.
