144Hz monitor only showing 120Hz: Fix refresh rate limits

When a gaming monitor supports 144 Hz but Windows displays only 120 Hz, the cause is usually a connection limitation, an incorrect display setting, a graphics driver issue, or a restriction involving the current resolution. If your 144hz monitor only showing 120hz is preventing you from using its advertised refresh rate, start by checking the monitor’s specifications and Windows Advanced display settings. Then test the cable, video port, and GPU configuration before considering more advanced fixes. In most cases, you can identify the problem without replacing your monitor or graphics card.

144Hz monitor only showing 120Hz: what to check first

A monitor rated for 144 Hz does not necessarily offer that refresh rate through every input or resolution. The monitor, graphics card, video cable, and operating system must support the same display mode for Windows to offer it.

Intel’s support guidance for monitors stuck at 120 Hz specifically recommends checking Windows refresh-rate settings, cable bandwidth, display compatibility, and graphics drivers. These are the best starting points when a previously available 144 Hz option disappears.

The most common causes include:

• Windows is configured to use 120 Hz instead of 144 Hz.

• The HDMI or DisplayPort connection does not support the required resolution and refresh rate.

• A cable, adapter, docking station, or KVM switch limits the available display modes.

• The selected resolution or color configuration restricts the signal.

• A graphics driver update or configuration issue prevents the expected mode from appearing.

• The monitor requires a manufacturer-specific setting to enable its highest refresh rate.

• The computer’s external video output has a lower supported limit than the monitor itself.

Use this table to narrow down the cause before changing multiple settings.

Do not assume that a monitor advertised as 144 Hz is defective simply because Windows offers 120 Hz. The first objective is to determine whether the missing mode is a software configuration issue or a hardware compatibility limitation.

How to fix a 144Hz monitor only showing 120Hz in Windows

Start with the operating system because changing the refresh rate is straightforward and does not require installing additional software.

Select 144 Hz in Windows 11

Follow these steps:

1. Right-click an empty area of the desktop and select Display settings.

2. Open Advanced display.

3. If multiple screens are connected, select the monitor you want to troubleshoot.

4. Locate the Choose a refresh rate dropdown.

5. Select 144 Hz if the option is available.

6. Confirm the change and check that the screen remains stable.

After applying the setting, reopen Advanced display to confirm the selected refresh rate and resolution.

Microsoft explains that the available refresh rates depend on the display’s supported modes. Windows may also mark some rates with an asterisk when they do not support the current resolution. Selecting one of those modes can cause the display resolution to change.

If 144 Hz appears but the resulting resolution is lower than expected, return to the dropdown and choose a supported combination that preserves your preferred resolution.

If the dropdown offers only 120 Hz, continue with the connection checks. Repeatedly reopening Windows settings will not overcome a limitation in the monitor, cable, or graphics output.

Check refresh-rate settings in Windows 10

Windows 10 provides another route through the display adapter properties.

1. Right-click the desktop and open Display settings.

2. Select Advanced display settings.

3. Choose the correct monitor.

4. Select Display adapter properties for the display.

5. Open the Monitor tab.

6. Check the Screen refresh rate menu for 144 Hertz.

If 144 Hz appears, select it and apply the change. If it does not, return to the monitor’s specifications and verify the current input and resolution.

Menu layouts can differ depending on the graphics driver, so the option may appear in the main display settings or in the adapter properties. The objective is the same: select a supported refresh rate for the correct display.

Make sure you are changing the correct display

This step is easy to overlook in a dual-monitor setup.

Windows maintains separate display settings for each screen. Your primary monitor might support 144 Hz, while a secondary monitor is limited to 60 Hz or 120 Hz. Changing the wrong display will not fix the problem.

Use the Identify function in Display settings to match each numbered screen with the physical monitor. Then select the screen that supports 144 Hz and inspect its refresh-rate options.

If you recently rearranged your displays, disconnected a television, changed graphics cards, or updated a driver, verify the selected monitor before moving on.

Check the HDMI or DisplayPort connection

If Windows does not offer 144 Hz, the next step is to determine whether the entire video connection supports the desired mode.

A monitor and GPU can both support 144 Hz individually while the connection between them prevents that combination from working.

Verify the monitor’s input specifications

Find the exact monitor model on its rear label, in its OSD information page, or in the original purchase records. Look up the matching manufacturer’s manual and specifications.

Check the maximum refresh rate supported by each input at your intended resolution. Do not assume that the HDMI and DisplayPort connections have identical capabilities.

For example, Intel’s guidance for achieving 1920 × 1080 at 144 Hz identifies HDMI 2.0 and DisplayPort 1.2 as supported output options in the context covered by that article. However, this should not be interpreted as a universal connector rule for every monitor and graphics card. Implementation details vary, so the exact specifications of your devices take priority.

Look for three details:

• The maximum refresh rate supported by the monitor’s active input.

• The maximum refresh rate supported by the computer’s video output.

• The resolution and signal configuration supported by both ends of the connection.

If your monitor manual specifies DisplayPort for 144 Hz, use that input when testing. If the manufacturer confirms that the HDMI port supports 144 Hz at your resolution, HDMI may be suitable as well.

Try another compatible cable

An older, damaged, or unsuitable cable can limit available display modes or cause instability.

Disconnect and reconnect the cable securely at both ends. If possible, test with the cable supplied with the monitor or another known-good cable rated for the required signal.

Avoid judging a cable solely by its connector shape or by claims that it supports a particular resolution. The full configuration matters, including the monitor input, GPU output, resolution, refresh rate, and any additional signal features.

If you are using DisplayPort, try another compatible DisplayPort cable. If you are using HDMI, use a cable appropriate for the bandwidth specified by the monitor and computer manufacturers.

A cable swap is especially useful when the monitor worked at 144 Hz previously but became limited to 120 Hz after moving the PC, reconnecting the display, or adding an adapter.

If the new cable restores 144 Hz, there is no need to replace the monitor or GPU.

Remove adapters and docking stations temporarily

If the monitor connects through a USB-C hub, laptop dock, HDMI adapter, splitter, or KVM switch, bypass that device during troubleshooting.

Connect the monitor directly to a compatible video output and check Windows again.

An intermediary device may have a lower supported refresh rate than the monitor or computer. It may also impose restrictions based on the combination of displays connected to it.

If 144 Hz appears through a direct connection but disappears when you reconnect the dock, investigate the dock’s specifications and supported display modes. The issue is then more likely to involve the connection chain than a defective monitor.

Do not purchase a new graphics card before completing this test. A direct connection may solve the problem without any hardware upgrade.

Check the graphics card and computer output

Your computer’s video output must support the same display mode as your monitor. This matters particularly on systems with integrated graphics, dedicated graphics cards, and multiple physical video outputs.

Connect the monitor to the correct GPU output

On a desktop PC with a dedicated graphics card, check whether the display cable is connected to the graphics card rather than an unsuitable motherboard video output.

A motherboard output may depend on integrated graphics, whose capabilities can differ from those of the dedicated GPU. The available ports and supported modes also depend on the computer’s hardware configuration.

Turn off the PC before changing physical connections if the manufacturer recommends doing so. Then connect the monitor to a suitable GPU output and recheck the refresh rate.

This is particularly useful if you recently assembled the computer, replaced the GPU, or moved the monitor cable while cleaning your setup.

Check a laptop’s external display capabilities

A laptop’s internal display may support a different refresh rate from its external video ports. A powerful GPU does not guarantee that every HDMI or USB-C output can deliver every supported monitor mode.

Check the specifications for your exact laptop and port. For USB-C, verify that the port supports video output through the required technology rather than assuming that every USB-C connector can carry a high-refresh display signal.

If the laptop has multiple outputs, test the connection that the manufacturer confirms supports the required resolution and refresh rate.

When using a dock, check its capabilities separately from the laptop’s. The dock, cable, computer output, and monitor input must all support the intended mode.

Update or reinstall the graphics driver

If your monitor previously worked at 144 Hz but now shows only 120 Hz, a graphics driver problem deserves attention.

A driver update, Windows update, or hardware change can affect which display modes are available. However, a missing refresh rate does not automatically mean that the driver is defective, so check the physical connection first.

Update the driver through the official source

Identify the active graphics hardware and obtain the appropriate driver from NVIDIA, AMD, Intel, or your computer manufacturer’s support page.

Install the driver, restart the computer, and reopen Advanced display.

Laptop users should check their system manufacturer’s support resources, particularly when the computer uses hybrid graphics or customized display routing. An OEM-provided driver may be relevant to a specific model even when the GPU manufacturer offers a general driver.

Avoid downloading display drivers from unfamiliar websites. A collection of third-party refresh-rate utilities is not necessary for normal troubleshooting.

Consider a clean driver installation

If the 144 Hz option disappeared after a driver change, or if the graphics software behaves incorrectly, consider a clean installation using the GPU manufacturer’s documented procedure.

Intel specifically recommends a clean graphics driver installation when a monitor remains stuck at 120 Hz and the refresh-rate option is unavailable.

After reinstalling the driver, check both Windows Advanced display and the graphics control panel. If the maximum available rate remains 120 Hz, revisit the cable and monitor specifications rather than repeatedly reinstalling the same driver.

A driver cannot make an unsupported physical input deliver a mode beyond its capabilities.

Check the graphics control panel

Windows is not the only place where you can select a refresh rate. NVIDIA and AMD software provide display configuration options that can help you identify whether the expected mode is available to the driver.

Use NVIDIA Control Panel

On a system with a supported NVIDIA GPU:

1. Right-click the desktop and open NVIDIA Control Panel.

2. Under Display, select Change resolution.

3. Select the correct monitor.

4. Check the available resolutions and refresh rates.

5. Choose the native resolution and 144 Hz if the supported mode is listed.

NVIDIA documents Change resolution as the location for selecting a monitor’s refresh rate.

If 144 Hz appears in NVIDIA Control Panel, apply the supported setting and check the active refresh rate in Windows afterward.

If 144 Hz is missing from both interfaces, the cause may be the connection, supported display modes, resolution, or driver configuration.

NVIDIA also provides custom-resolution functionality, but forcing a rate outside the manufacturer’s specifications is not a recommended first-line fix. NVIDIA warns that unsupported custom timings may damage a display and potentially affect warranty coverage.

Check AMD Software or Intel graphics settings

AMD Software: Adrenalin Edition includes custom-resolution functionality for supported configurations. Intel graphics also exposes supported display modes through Windows and applicable graphics software.

Start by checking the modes already offered at the monitor’s native resolution. If 144 Hz is absent, verify the monitor’s supported configuration and driver before considering a custom mode.

AMD’s documentation emphasizes that compatibility depends on the display’s capabilities and specifications. A custom mode can be rejected if the display does not support the requested configuration.

Do not confuse the maximum refresh rate with gaming performance. A GPU can output a 144 Hz desktop signal even if it cannot render every game at 144 FPS. Those are separate capabilities.

Check resolution, HDR, and multiple-monitor settings

If the cable, ports, and drivers appear correct, temporarily simplify the signal configuration to determine whether another display setting is responsible.

Restore the native resolution

Open Display settings and choose the monitor’s recommended resolution.

For many Full HD monitors, this is 1920 × 1080. Many QHD monitors use 2560 × 1440. Check the exact specifications rather than assuming the resolution based on screen size.

Reopen Advanced display and inspect the refresh-rate options.

If 144 Hz appears at the native resolution, retain that supported combination. If it appears only after selecting a lower resolution, the original mode may exceed a limitation in the active signal path.

Avoid keeping the display at a lower resolution solely to gain the missing refresh rate unless that is an intentional trade-off. A non-native resolution can reduce image sharpness.

Test with HDR disabled

If HDR is enabled, turn it off temporarily in Windows and check the refresh-rate menu again.

Resolution, refresh rate, color depth, and other signal features affect the requirements of a display connection. A configuration that works at 120 Hz may not support every additional feature at 144 Hz through the same cable and port.

If disabling HDR restores 144 Hz, you have narrowed down the possible cause. Check the specifications for your monitor and GPU to determine whether both features can operate together at the desired resolution.

Do not assume that HDR must remain disabled permanently. The purpose of this test is to isolate the restriction, not to sacrifice image quality unnecessarily.

Test with only one monitor connected

Disconnect secondary displays temporarily and test the 144 Hz monitor by itself.

Multiple monitors do not automatically prevent 144 Hz, but they introduce extra variables, including docks, shared outputs, and different resolution requirements.

If the monitor reaches 144 Hz when connected alone, reconnect the other displays one at a time. Check whether the refresh-rate option changes after adding a particular screen or adapter.

This approach can identify whether the problem comes from the combined display configuration rather than the monitor itself.

Troubleshooting symptoms when 144Hz is missing

Use the following table to select the next step based on what happens during our research.

If none of the standard checks works, record your exact monitor model, GPU or laptop model, connection type, resolution, and available refresh rates. That information will help the monitor or computer manufacturer investigate a model-specific limitation.

Avoid forcing higher timings repeatedly when the screen is unstable. A reliable 120 Hz mode is preferable to an unsupported configuration that causes signal loss.

Frequently asked questions

Is 120Hz significantly worse than 144Hz?

Both provide smooth motion compared with conventional 60 Hz operation. The theoretical interval between refreshes is about 8.33 milliseconds at 120 Hz and 6.94 milliseconds at 144 Hz. The difference is real but relatively small, so restoring 144 Hz is worthwhile if your hardware supports it, not a reason to replace otherwise functional equipment.

Can an HDMI cable limit a 144Hz monitor to 120Hz?

Yes, a cable or HDMI connection can be a limiting factor. However, the result depends on the exact cable, monitor input, GPU output, resolution, and signal configuration. Check the device specifications before buying a replacement cable.

Will a better graphics card fix the missing 144Hz option?

Not necessarily. If the current GPU output already supports the required display mode, the problem may be a cable, adapter, setting, or driver. Upgrade only after confirming that the existing hardware cannot support the monitor’s required resolution and refresh rate.

Should I create a custom 144Hz resolution?

Only consider this after confirming the monitor’s documented capabilities and troubleshooting supported modes. Custom resolutions are not a safe workaround for every connection limitation. NVIDIA warns that custom modes beyond advertised specifications can cause permanent damage and may affect warranty coverage.

Does running a game at 120 FPS mean the monitor is limited to 120Hz?

No. Refresh rate and frame rate are different. Windows can run the display at 144 Hz while a game renders at 120 FPS or less. Check Advanced display to confirm the monitor’s active refresh rate, then investigate the game’s frame-rate cap and graphics settings separately.

Final verdict

If your 144 Hz monitor only shows 120 Hz, start with Windows Advanced display settings and confirm that you selected the correct monitor. Then verify the supported input, cable, resolution, and GPU output. If the problem persists, update the graphics driver and test the display without adapters, HDR, or secondary monitors.

The key is to identify the actual limitation before spending money or forcing custom timings. Follow the manufacturer’s supported configuration, confirm that Windows reports the intended refresh rate, and keep a stable mode as your fallback. You should not need to replace the monitor simply because 144 Hz is missing from the initial dropdown.
