Learning how to check monitor refresh rate is useful whether you are troubleshooting a display, setting up a gaming PC, or simply trying to make everyday movement look smoother. Refresh rate describes how many times a monitor can update its picture every second. A display running at 60 Hz refreshes 60 times per second, while a 144 Hz model can refresh 144 times per second. However, the rate advertised on the box is not always the rate currently selected by your computer. Operating system settings, graphics drivers, cables, ports, and screen resolution can all affect the available options. In this guide, you will learn how to find your current refresh rate on Windows, macOS, and Linux, confirm that the setting works correctly, and solve common problems. You will also discover when a higher rate matters, which hardware factors to inspect, and how to avoid settings that make a capable monitor run below its full potential.
What Monitor Refresh Rate Means
A monitor’s refresh rate is measured in hertz, usually written as Hz. One hertz represents one screen update per second, so a 120 Hz display can produce up to 120 separate updates each second.
Refresh rate is different from resolution. Resolution describes the number of pixels displayed, while refresh rate describes how frequently those pixels can change. A monitor can therefore support several combinations, such as 4K at 60 Hz or 1440p at 144 Hz.
It is also different from frame rate. Frames per second measure how quickly a game or application creates images. Refresh rate measures how quickly the monitor can show them. The two values work together, but they do not need to be identical.
Common rates include 60 Hz, 75 Hz, 100 Hz, 120 Hz, 144 Hz, 165 Hz, 240 Hz, and 360 Hz. Some screens use values such as 59.94 Hz because of established video timing standards. An operating system may round that figure and display it as 60 Hz.
A higher number generally makes scrolling, pointer movement, animation, and gaming appear smoother. The difference is especially visible during fast motion, although the practical benefit depends on the content, computer performance, and sensitivity of the viewer.
Why Checking Your Refresh Rate Matters
A quick refresh rate check can reveal whether your display is operating as intended and help you diagnose motion or image-quality problems.
- Use Full Monitor Performance: A high-refresh monitor may remain at 60 Hz until its faster mode is selected manually in the operating system.
- Improve Motion Clarity: Higher rates can make fast movement easier to follow and reduce the jumpy appearance of scrolling or camera turns.
- Reduce Gaming Delay: More frequent screen updates can show newly rendered information sooner, which is helpful in responsive and competitive games.
- Find Connection Limits: Missing refresh rate choices may indicate that a cable, adapter, dock, or display port lacks enough bandwidth.
- Troubleshoot Display Changes: Driver updates, new resolutions, and replaced cables can sometimes cause a system to return to a lower setting.
- Balance Quality And Performance: Checking available combinations helps you choose between a sharper resolution, a faster refresh rate, or a practical balance of both.
How To Check Refresh Rate On Windows
Windows provides the current refresh rate through its display settings. Menu names may vary slightly between versions, but the essential information appears in the advanced display area.
1. Open The Display Settings
Right-click an empty part of the desktop and select the display settings option. You can also open Settings and choose System followed by Display. This page controls resolution, scaling, orientation, and multiple-monitor arrangements, so confirm that Windows has detected every connected screen before continuing.
2. Select The Correct Monitor
If you use more than one display, choose the monitor you want to inspect in the screen arrangement diagram. Select Identify if you are unsure which numbered display matches the physical monitor. Refresh rate settings apply separately, so checking the wrong screen can produce a misleading result.
3. Open Advanced Display
Scroll through the display page and open Advanced display. Windows will show technical information for the selected screen, including its desktop resolution, active signal resolution, color format, bit depth, and current refresh rate. This value shows the rate being sent to the monitor.
4. Review The Current Rate
Look for the refresh rate value or the option labeled Choose a refresh rate. If it says 60 Hz while you own a 144 Hz monitor, the faster mode is not currently active. A value near 59.94 Hz is generally the standard 60 Hz timing rather than a fault.
5. Choose A Supported Refresh Rate
Open the refresh rate menu and select the desired option. Windows may briefly turn the screen black while the signal changes. Keep the setting if the picture returns normally. If the display becomes unstable, wait for Windows to restore the previous configuration automatically.
6. Check Graphics Adapter Properties
If the expected option is missing, open the display adapter properties from the advanced display page. The Monitor tab may provide another refresh rate menu, while List All Modes shows supported combinations of resolution, color depth, and frequency. Select only a mode supported by the monitor.
How To Check Refresh Rate On macOS
Apple computers display refresh rate controls in the Displays area. Available choices depend on the Mac, monitor, connection, selected resolution, and whether the built-in screen supports an adaptive technology such as ProMotion.
1. Open System Settings
Select the Apple menu and open System Settings, then choose Displays. On older macOS versions, open System Preferences and select Displays instead. The page shows each recognized screen and its available configuration controls, including resolution, color profile, rotation, and refresh rate.
2. Choose The Intended Display
Select the external monitor or built-in display that you want to check. When several screens are connected, macOS maintains separate settings for each one. Verify the model shown in the panel so you do not accidentally inspect a laptop screen while troubleshooting an external gaming monitor.
3. Find The Refresh Rate Menu
Look for the Refresh Rate setting in the selected display’s controls. The current choice may appear as a fixed number, such as 60 Hz or 120 Hz, or as an adaptive option. If the control is absent, the present hardware combination may expose only one supported rate.
4. Review Adaptive Refresh Options
Some Mac displays automatically vary their refresh rate to match activity and save power. An adaptive setting does not mean the screen constantly operates at its maximum rate. It can increase during scrolling or animation and decrease when the image is static or content uses a lower frame rate.
5. Test Another Resolution
If the expected rate is unavailable, review the resolution choices. A monitor and connection may support a high refresh rate at 1440p but only a lower rate at 4K. Choosing another scaled or native resolution can reveal additional options, although text size and image sharpness may change.
6. Inspect The Connection
A compatible Mac can still be limited by its adapter, hub, docking station, cable, or display input. Connect the monitor directly when possible and use equipment rated for the desired resolution and refresh rate. Then reopen Displays and check whether macOS offers the missing selection.
How To Check Refresh Rate On Linux
Linux users can usually view and change the refresh rate through the desktop display panel. Exact labels differ among distributions and desktop environments, while command-line utilities can provide additional details when graphical settings are unclear.
1. Open The Display Panel
Open the system settings for your desktop environment and choose Displays, Screen Display, or a similarly named option. This area normally presents screen arrangement, orientation, scaling, resolution, and refresh rate. Select the relevant monitor before interpreting any reported value or changing its mode.
2. Read The Active Frequency
Find the refresh rate or frequency menu and note the selected value. Common entries include 60.00 Hz, 119.88 Hz, and 143.98 Hz. Slight differences from round advertised numbers are normal because display timings often use fractional rates rather than exact whole-number frequencies.
3. Check Each Connected Screen
When multiple displays are present, inspect them individually. Some desktop setups can run screens at different rates, while particular compositors, graphics drivers, or mirroring modes may create restrictions. Extended desktop mode usually offers more flexibility than duplicating one image across monitors with different capabilities.
4. Review Available Display Modes
Open the refresh rate menu after selecting the desired resolution. The list reflects modes reported by the monitor and accepted by the graphics system. If a high rate appears only at a lower resolution, bandwidth is probably limiting the current combination rather than the monitor being incorrectly identified.
5. Confirm The Graphics Driver
Linux display options depend heavily on correct graphics support. An unsuitable or incomplete driver may hide modes, limit acceleration, or cause unstable output. Review the distribution’s hardware information and driver management settings to confirm that the intended graphics device and recommended driver are active.
6. Account For Wayland And X11
Results can differ between Wayland and X11 sessions because they manage displays and mixed refresh rates differently. If a mode behaves unexpectedly, note which session type is running and compare the graphical settings there. Avoid forcing custom timings until ordinary settings and hardware connections have been checked.
How To Check Refresh Rate Through Monitor Controls
The monitor’s on-screen display can provide a useful second source of information. Use these steps to inspect the signal received directly by the screen.
- Open The Monitor Menu: Press the physical button or joystick located along the side, back, or lower edge of the display.
- Find Signal Information: Look for Information, Status, Input Details, or a similar menu item rather than picture presets.
- Read The Reported Frequency: Note the resolution and vertical frequency shown for the active input.
- Compare Both Values: Check whether the monitor’s report matches the rate displayed by the operating system.
- Confirm The Active Input: Make sure you are viewing information for the HDMI or DisplayPort connection currently in use.
- Disable Confusing Overlays: Remember that an on-screen frame counter may report game performance rather than the fixed signal rate.
- Repeat After Changes: Reopen the information page after selecting a different rate to confirm that the monitor received the new mode.
How To Verify The Refresh Rate Is Working
A settings page confirms the selected signal mode, but a practical check helps show whether applications, graphics performance, and monitor behavior are producing the expected experience.
1. Move Windows And Scroll
Drag a window across the desktop and scroll through a long page. Motion should appear clearer and more continuous at 120 Hz or 144 Hz than at 60 Hz. This simple comparison is subjective, but it can reveal an obvious failure to apply the higher setting.
2. Check Game Display Settings
Open the video or graphics menu inside a game and review its resolution, display mode, frame limit, and refresh rate. Exclusive full-screen applications may use a mode different from the desktop. Borderless applications commonly inherit the operating system’s active desktop configuration instead.
3. Monitor Frame Rate Separately
A monitor running at 144 Hz cannot make a game render 144 frames per second. Use a performance overlay when available to view frame rate separately. If the computer produces only 45 frames per second, motion will not demonstrate the full benefit of the faster display.
4. Compare Known Settings
Switch temporarily between 60 Hz and the desired higher rate, then repeat the same scrolling or cursor movement. A direct comparison is easier to judge than relying on memory. Return to the preferred rate afterward and confirm that the operating system kept the selection.
5. Watch For Signal Problems
Flickering, random black screens, colored sparkles, or repeated disconnections can indicate an unreliable cable, marginal adapter, unsupported timing, or unstable custom setting. A mode appearing in a menu does not guarantee dependable operation, so test normal applications and games before considering the setup complete.
6. Restart And Recheck
Restart the computer and revisit the advanced display settings. This confirms that the chosen mode persists after a fresh hardware detection cycle. If it returns to a lower rate, investigate graphics drivers, monitor identification, startup utilities, docking hardware, and any application that manages display profiles.
Factors That Limit Monitor Refresh Rate
The maximum rate shown in settings depends on the complete signal path, not only the number printed in the monitor specifications.
- Monitor Capability: Each display supports particular combinations of resolution and refresh rate, which may also vary between its input ports.
- Graphics Hardware: The graphics processor and its output must support enough bandwidth for the requested resolution, color depth, and frequency.
- Cable And Adapter: An older cable, passive adapter, hub, or dock can become the weakest part of an otherwise capable setup.
- Selected Resolution: Higher resolutions transmit more pixel data and may reduce the maximum refresh rate available through a connection.
- Color Configuration: High bit depth, chroma settings, and high dynamic range can increase bandwidth requirements and change the available display modes.
- Graphics Driver: Missing, outdated, or incorrect drivers may prevent the operating system from reading or applying the monitor’s supported modes properly.
Common Refresh Rate Mistakes To Avoid
Most refresh rate problems come from configuration or connection issues rather than a defective monitor. Avoiding these mistakes can save considerable troubleshooting time.
1. Assuming The Highest Rate Is Automatic
Many computers initially use a safe 60 Hz mode even when the connected monitor supports much more. Do not rely on the product specification alone. Check the active setting after connecting a new screen, reinstalling an operating system, changing graphics hardware, or updating important drivers.
2. Checking The Wrong Display
In a multi-monitor setup, it is easy to select the laptop panel or secondary office screen instead of the high-refresh display. Use the Identify function and match the displayed numbers carefully. Every monitor can have its own resolution and refresh rate, even on one desktop.
3. Confusing Refresh Rate With Frame Rate
A 165 Hz monitor describes display capability, not guaranteed game performance. Frame rate comes from the computer’s rendering workload. Treat the values separately when diagnosing motion. You may have the correct refresh rate but still need to adjust game settings for a higher frame rate.
4. Ignoring Cable And Port Limits
A cable that produces an image is not necessarily suitable for the monitor’s fastest mode. Different ports on the same monitor can also support different limits. Review the capabilities of the graphics output, cable, adapter, dock, and monitor input as one complete connection.
5. Forcing Unsupported Custom Modes
Custom resolutions and timings can sometimes expose additional options, but careless values may cause blank screens, artifacts, or unstable signals. Use supported modes first. Only experienced users should attempt custom settings, and they should always keep a known working configuration available for recovery.
6. Forgetting Application Overrides
Some games and media applications can select their own full-screen mode, enable a frame cap, or switch the display when launched. If the desktop looks correct but one application does not, inspect that application’s video settings before repeatedly changing the global operating system configuration.
Best Practices For Monitor Refresh Rates
Once you know how to check monitor refresh rate settings, a few habits can keep the display stable, responsive, and correctly configured.
1. Use A Native Resolution
Start with the monitor’s native resolution because it normally produces the sharpest image and the most predictable scaling. Then select the highest stable refresh rate supported at that resolution. Reduce resolution only when extra speed provides a meaningful advantage or hardware bandwidth requires it.
2. Choose Certified Connection Hardware
Use a well-made cable and adapter designed for the required signal standard and bandwidth. Excessively long or poor-quality connections can become unreliable at high data rates. Direct connections are preferable during troubleshooting because docks and converters introduce additional capabilities and possible limitations.
3. Keep Graphics Drivers Current
Install appropriate graphics drivers and review display settings after major updates. New drivers may improve monitor detection and resolve compatibility problems, although settings can occasionally change during installation. Rechecking the active resolution and rate takes only a moment and confirms that performance remains available.
4. Match Performance To The Display
Choose graphics settings that let demanding applications deliver a useful frame rate for the monitor. A balanced configuration often feels better than maximum visual detail with irregular performance. Variable refresh rate can further improve presentation when frame output changes within the monitor’s supported operating range.
5. Test Stability Before Daily Use
Run ordinary desktop tasks, video, and demanding games after selecting a faster mode. Look for flicker, signal loss, artifacts, or unusual heat from adapters. A slightly lower but completely stable rate is more useful than an unreliable maximum setting that regularly interrupts work or play.
6. Recheck After Hardware Changes
Inspect the setting whenever you replace a cable, move to another port, add a docking station, install a graphics card, or connect additional monitors. Hardware changes can alter available bandwidth and trigger automatic configuration. A quick review ensures that the preferred mode remains active.
Frequently Asked Questions
1. Is 60 Hz Good Enough For Everyday Use?
Yes, 60 Hz is adequate for browsing, office documents, video playback, and many casual activities. A higher rate can make scrolling and pointer movement feel smoother, but it is not essential for every user. The best choice depends on your workload, preferences, hardware, and budget.
2. Why Does My 144 Hz Monitor Show Only 60 Hz?
The operating system may still be using its default mode, or the selected resolution may exceed the connection’s bandwidth at 144 Hz. An unsuitable cable, adapter, dock, graphics port, or driver can also remove the option. Check the complete connection and advanced display settings.
3. Is 59.94 Hz The Same As 60 Hz?
For normal use, 59.94 Hz and 60 Hz are effectively treated as the same refresh rate. The fractional value comes from established video timing conventions. Its appearance is usually normal and does not suggest that the monitor is damaged or meaningfully underperforming.
4. Can A Higher Refresh Rate Damage A Monitor?
Selecting a manufacturer-supported mode through standard operating system settings should not damage the monitor. Problems are more likely when users force unsupported custom timings or overclock the panel. If the picture becomes unstable, return to a documented resolution and refresh rate combination.
5. Does HDMI Support High Refresh Rates?
HDMI can support high refresh rates, but the exact capability depends on the HDMI versions and implementations used by the graphics output, cable, adapter, and monitor input. Resolution and color settings also affect bandwidth. Check every component rather than assuming all HDMI connections have identical limits.
6. Should Refresh Rate Match Frames Per Second?
They do not need to match exactly, but a suitable relationship can improve motion. Variable refresh rate technology allows a compatible monitor to adjust around changing frame output. Without it, synchronization settings or frame limits can help manage tearing, responsiveness, and uneven frame presentation.
Conclusion
Checking a monitor’s refresh rate is a straightforward way to confirm that your display is delivering the performance you expect. Windows, macOS, and Linux all provide the active value in their display settings, while the monitor’s information menu can independently confirm the received signal. Remember to distinguish refresh rate from frame rate and resolution.
If the expected option is missing, examine the entire connection, including the graphics hardware, output port, cable, adapter, dock, monitor input, driver, and selected resolution. Choose a supported rate, test it for stability, and recheck the setting after major hardware or software changes. These simple habits help maintain smooth, reliable display performance.
