One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchUnderstanding frame rate and refresh rate for gaming starts with one distinction: FPS is the number of frames the game and GPU render per second, while Hz is the number of times the display can update per second. A 144Hz monitor does not guarantee 144 FPS, and 200 FPS cannot make a 144Hz display show 200 complete refreshes.
When FPS and Hz are appropriately matched, frame pacing and motion can feel smoother and more responsive. When they are mismatched, the result can include repeated frames, uneven timing, tearing, or wasted rendering. VRR technologies such as FreeSync and G-SYNC help coordinate the two, but they do not add rendering power.

Key takeaways
- FPS is the number of frames a game or GPU renders per second, while Hz is the number of times a display can update per second.
- A 144Hz monitor can display up to 144 refreshes per second, but the monitor cannot guarantee that a game will render 144 FPS.
- If FPS exceeds a monitor’s refresh-rate ceiling, unsynchronized output can produce screen tearing because multiple frames may appear during one display update.
- VRR technologies such as AMD FreeSync and NVIDIA G-SYNC synchronize display timing with frame delivery, but they do not create frames or increase GPU performance.
- For many PC gamers, 120Hz or 144Hz is the strongest general-purpose target; 240Hz is most useful when games and hardware can sustain very high frame rates.
What is the difference between FPS and Hz?
FPS, or frames per second, describes how quickly the game and GPU render new images. Hz, or hertz, describes how quickly the monitor can refresh its image. FPS is produced by the game and hardware; refresh rate is a capability of the display. The two numbers work together, but FPS and Hz are not interchangeable.

A useful analogy is a camera and a flipbook. FPS describes how quickly new pages are produced, while Hz describes how quickly the screen turns pages. A smooth result depends on both the number of frames being rendered and how consistently the display presents them.

| Term | What it measures | What controls it | What it does not guarantee |
|---|---|---|---|
| FPS | Frames rendered by the game or GPU each second | GPU, CPU, game engine, resolution, graphics settings, and software | That the display can show every rendered frame |
| Hz | Display updates each second | Monitor or TV hardware, selected mode, resolution, port, and cable | That the game will render the same number of FPS |
| VRR | How flexibly the display adjusts its timing to frame delivery | Compatible display, GPU or console, driver settings, and supported VRR range | Higher GPU performance or a refresh rate beyond the display’s maximum |
Is 144Hz the same as 144 FPS?
No. A 144Hz monitor can refresh up to 144 times per second, while 144 FPS means that the game is rendering 144 frames per second. A game running at 80 FPS on a 144Hz monitor is still producing only 80 frames per second, although the monitor may refresh more often and repeat frames when fixed-refresh timing is used.
Conversely, a game rendering 200 FPS on a 144Hz monitor does not make the monitor display 200 complete refreshes per second. The display remains limited to its 144Hz ceiling. Extra rendered frames may sometimes reduce latency in particular configurations, but they do not all become separately visible complete refreshes.
What happens when FPS is below, equal to, or above refresh rate?
The relationship between FPS and Hz affects frame pacing, smoothness, latency, and tearing. Average FPS alone is not enough to describe how a game feels because uneven frame delivery can make a high average look stuttery.
| Relationship | What can happen on a fixed-refresh display | What VRR can change |
|---|---|---|
| FPS below Hz | The display may repeat frames or present them at uneven intervals. A game fluctuating between 45 and 60 FPS on a fixed 60Hz display may feel less consistent than its average suggests. | A compatible display can adjust its refresh timing to follow frame delivery within its supported VRR range. |
| FPS close to Hz | The system can present a new frame on nearly every refresh cycle, provided frame pacing and synchronization are consistent. | VRR can help accommodate small changes in frame delivery within the supported range. |
| FPS above Hz | The display cannot show every rendered frame as a separate full refresh. Unsynchronized output can show portions of multiple frames in one update, producing tearing. | VRR, V-Sync, or a frame-rate cap can coordinate presentation, with different latency and output trade-offs. |
Does FreeSync fix screen tearing, and does G-SYNC increase FPS?
FreeSync and G-SYNC can reduce or eliminate screen tearing and stutter when the display, graphics hardware, connection, and settings are compatible, but neither technology increases FPS. VRR changes when the display refreshes so the display can better follow when the GPU finishes a frame.
AMD describes FreeSync as synchronizing dynamic display refresh rates with Radeon frame rates. NVIDIA’s G-SYNC documentation describes the technology as targeting smooth graphics, low latency, and reduced tearing and stuttering.
NVIDIA distinguishes full G-SYNC displays, which use NVIDIA processors, from G-SYNC Compatible displays, which are validated for a basic VRR experience without a dedicated NVIDIA processor. FreeSync and G-SYNC are synchronization technologies, not rendering-performance upgrades.

V-Sync, VRR, FreeSync, and G-SYNC compared
| Technology | Primary purpose | Main limitation or trade-off |
|---|---|---|
| V-Sync | Synchronizes frame presentation with the display’s refresh cycle and can eliminate tearing. | Depending on the implementation and situation, V-Sync can cap output and affect latency. |
| VRR | Allows a compatible display to vary its refresh timing to follow frame delivery. | VRR works only within the display’s supported range and cannot create frames or exceed maximum Hz. |
| AMD FreeSync | AMD’s VRR ecosystem for compatible displays and Radeon graphics hardware. | Compatibility and supported behavior depend on the display, Radeon hardware, driver, connection, and VRR range. |
| NVIDIA G-SYNC | NVIDIA’s VRR display technology, available in full G-SYNC and G-SYNC Compatible implementations. | Features and validation differ between full G-SYNC and G-SYNC Compatible displays. |
When FPS is regularly above the display’s maximum, a frame-rate cap can reduce wasted rendering and help maintain steadier timing. V-Sync, VRR, Enhanced Sync, and frame-rate caps behave differently depending on the hardware and frame rate, so there is no universal setting that is best for every game.

You do not need 144Hz for every game, but 120Hz or 144Hz is a strong general-purpose choice for many PC gamers who want noticeably smoother motion and more responsive control than 60Hz. The value depends on sustained FPS, resolution, game type, GPU capability, VRR support, and the monitor’s overall image quality.
| Refresh-rate target | Best fit | Important qualification |
|---|---|---|
| 60Hz | General desktop work, slower-paced games, and systems that rarely exceed 60 FPS | A higher-refresh display will not help much if the system and games consistently remain near 60 FPS. |
| 120Hz or 144Hz | Many PC gamers seeking a substantial improvement over 60Hz without targeting extreme frame rates | Match the monitor with the GPU, resolution, games, VRR range, and connection. |
| 165Hz | Buyers who find a small price difference from 144Hz or who prefer a particular monitor’s resolution, HDR, panel, ergonomics, or VRR behavior | The increase over 144Hz is modest; other monitor qualities may matter more. |
| 240Hz and above | Competitive players whose games and hardware can sustain very high FPS | The number alone does not make a monitor better for every gamer. NVIDIA markets 360Hz G-SYNC displays toward competitive gaming and ultra-high frame rates. |
What should you look for in a high-refresh gaming monitor?
Choose a 144Hz gaming monitor when your games and system can make practical use of the refresh rate, then compare more than the headline Hz number. A monitor should be matched to sustained game FPS, resolution, VRR range, response behavior, input latency, connectivity, image quality, ergonomics, price, and upgrade plans.
For example, a 240Hz monitor may be a poor value if a GPU cannot sustain the required frame rate at the chosen resolution. A 144Hz monitor with a useful VRR range, suitable resolution, good image quality, and the correct ports may produce a better overall experience than a faster monitor with compromises elsewhere.
- Sustained FPS: Use the frame rate the system can maintain during real gameplay, not a brief peak.
- Resolution: Higher resolutions require more GPU rendering work.
- VRR range: Check the monitor’s documented lower and upper limits; a 48–144Hz range is only an example, not a universal specification.
- Response behavior: An advertised response time is not the same as independently measured motion quality, so do not judge a display by that number alone.
- Input latency: Consider the complete system, including the game, hardware, display mode, and peripherals.
- Image quality and ergonomics: Panel type, contrast, HDR, color, stand adjustment, and viewing distance can outweigh a small Hz difference.
- Connectivity: Confirm that the chosen port and cable support the desired resolution and refresh-rate mode.
How do you enable 144Hz on a monitor in Windows?
To enable 144Hz in Windows, open Settings → System → Display → Advanced display, select the correct monitor, and choose a supported refresh rate. Microsoft’s Windows refresh-rate instructions note that available rates depend on the selected display and current resolution.
- Select the intended monitor if multiple displays are connected.
- Confirm the desired resolution before selecting the refresh rate.
- Choose 144Hz, or the highest supported rate appropriate for the setup.
- Check whether Windows reports variable-refresh-rate support.
- Enable Adaptive-Sync or the monitor’s equivalent in the monitor’s on-screen menu if required.
- Enable the matching AMD or NVIDIA driver feature when applicable.
- Check the game’s display settings because a game can use a separate lower refresh-rate mode.
If Windows does not offer 144Hz, check the monitor input, selected resolution, GPU output, cable, and whether the monitor’s on-screen menu has a high-refresh mode disabled. A display may expose different refresh rates at different resolutions or through different ports.

What is Windows 11 Dynamic Refresh Rate?
Windows 11 Dynamic Refresh Rate, or DRR, can alter refresh behavior dynamically, but Microsoft says DRR requires VRR support and at least 120Hz. If a game behaves unexpectedly or a non-VRR game is limited to a lower maximum refresh rate, test the setup with DRR disabled.
Do you need HDMI 2.1 for 120Hz gaming?
No, HDMI 2.1 is not automatically required for every 120Hz setup. The required connection depends on the resolution, color mode, display input, GPU or console output, and cable. A 1080p or 1440p 120Hz mode may be supported over a different connection, while a 4K 120Hz setup requires checking the complete signal path.
The HDMI 2.1b specification page lists support for modes including 8K60 and 4K120, bandwidth up to 48Gbps, and gaming features including VRR. The HDMI organization identifies an Ultra High Speed HDMI Cable for bandwidth-dependent HDMI 2.1 features.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For a console or PC targeting 4K120, verify all four links:
- The GPU or console output capability
- The monitor or TV input capability
- The selected resolution and color mode
- The cable category and certification
A cable cannot create extra FPS. A cable can determine whether the source and display successfully negotiate the desired resolution and refresh-rate mode. DisplayPort may be the preferred connection for a particular PC monitor, but the exact supported refresh rate remains model-specific and depends on the monitor, GPU, port version, resolution, compression mode, and cable.
Why does a game feel stuttery even with high FPS?
A game can feel stuttery with high average FPS because frame delivery is uneven. Average FPS can hide frame-time spikes caused by shader compilation, CPU spikes, asset streaming, background processes, thermals, drivers, game patches, or a game-specific problem.

|---|---|---|
| Low FPS | The game or GPU is not rendering enough frames. | Check resolution, graphics settings, GPU utilization, CPU limitations, thermals, background processes, game patches, and drivers. |
| Low refresh rate | The display is operating below its intended update rate. | Check Windows Advanced display, the monitor menu, selected resolution, cable, port, and whether the game changed display mode. |
| Tearing | Frames are being presented out of sync with the display cycle. | Consider VRR, V-Sync, a frame-rate cap, or vendor synchronization settings, while accounting for latency trade-offs. |
| Stutter with high average FPS | Frame pacing is uneven rather than simply too slow. | Look for frame-time spikes, shader compilation, CPU spikes, asset streaming, background work, thermal throttling, and game-specific issues. |
Should you update graphics drivers to fix low FPS?
Updating graphics drivers can be a sensible troubleshooting step when an outdated or corrupted driver is involved, but a driver update is not a guaranteed FPS upgrade. Check the GPU manufacturer’s official driver source first and verify the recommended update before installing it.
Outbyte Driver Updater describes scanning for outdated, corrupted, or missing Windows drivers and recommending updates from official sources. That makes driver maintenance a possible troubleshooting option, not proof that the software will increase game performance.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What does a cable change, and what can it not change?
A cable can affect whether a display exposes a desired resolution, refresh rate, color mode, or VRR mode. A cable cannot increase the FPS rendered by the game or GPU. When troubleshooting a missing 144Hz or 4K120 option, verify the cable category, port, source, display input, resolution, and color settings together.
Can gameplay streaming improve FPS or refresh rate?
No. A streaming service does not improve a game’s local FPS or a monitor’s refresh rate. A separate creator use case is looping owned gameplay replays, tutorials, or demonstrations as a 24/7 gameplay replay stream; the footage must be content the user owns or has permission to submit. StreamNeo’s terms set out that rights-and-permissions requirement.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsWhich matters more: FPS or Hz?
Neither number is sufficient by itself. FPS determines how frequently the game produces new frames, while Hz determines how frequently the display can present updates. For a balanced setup, target a refresh rate your monitor supports, a sustained FPS range your hardware can deliver, and VRR or another synchronization method that keeps frame presentation consistent.
For many gamers, a 120Hz or 144Hz display with compatible VRR is a sensible balance. Competitive players with high-refresh hardware and games that sustain very high frame rates may benefit from 240Hz or more. Slower-paced games and systems near 60 FPS can remain well served by 60Hz.

Frequently Asked Questions
Is 144Hz the same as 144 FPS?
No. A 144Hz monitor can refresh up to 144 times per second, but the game and GPU must actually render 144 FPS to provide 144 new frames per second. A game running below 144 FPS will not be transformed into a 144-FPS game by the monitor.
Do I need HDMI 2.1 for 120Hz gaming?
No. HDMI 2.1 is not required for every 120Hz setup. The requirement depends on resolution, color mode, display input, GPU or console output, and cable. For 4K120, verify every part of the signal chain and consider an Ultra High Speed HDMI Cable where HDMI 2.1 bandwidth is required.
Does FreeSync fix screen tearing, and does G-SYNC increase FPS?
FreeSync and G-SYNC can reduce tearing and stutter by synchronizing display timing with frame delivery on compatible hardware, but neither technology creates frames or increases GPU performance. VRR also cannot exceed the monitor’s maximum refresh rate.
Why does my game feel stuttery even with high FPS?
A high average FPS can still feel stuttery when frame delivery is uneven. Shader compilation, CPU spikes, asset streaming, background processes, thermals, drivers, and game-specific issues can create frame-time spikes that an average-FPS counter hides.
The Bottom Line
FPS is what the game renders; Hz is what the display can refresh. A 144Hz monitor does not guarantee 144 FPS, and 200 FPS cannot make a 144Hz display show 200 complete refreshes per second. Match the monitor’s refresh rate, VRR range, resolution, ports, and price to the FPS your system can sustain.
