A monitor that should run at 144Hz can fall back to 60Hz, 120Hz, or another lower refresh rate for several reasons: Windows may be set incorrectly, the cable may not have enough bandwidth, the GPU driver may be misconfigured, or the monitor’s on-screen display may be limiting the input mode. The panel is usually not defective.
Start by confirming the actual refresh rate in Windows and in the monitor’s own on-screen display (OSD). A game reporting high frame rates does not mean the display is receiving a 144Hz signal. Likewise, a monitor can be capable of 144Hz only at certain resolutions, ports, color settings, or adaptive-sync modes. This guide covers the most practical checks for a modern Windows gaming PC in 2026.
Most Common Causes
| Cause | Symptom | Likelihood |
|---|---|---|
| Windows refresh-rate setting is still at 60Hz | Desktop and games feel capped despite a 144Hz monitor | Very high |
| Incorrect, damaged, or low-bandwidth cable | 144Hz option is missing, especially at native resolution | Very high |
| Connected through a limited monitor port, adapter, dock, or AV receiver | Lower refresh rates appear only when using a particular input path | High |
| GPU control-panel resolution or color setting limits bandwidth | 144Hz disappears when HDR, 10-bit color, or a custom resolution is enabled | High |
| Monitor OSD is set to a compatibility, HDMI, or lower-refresh mode | Monitor reports 60Hz or 120Hz even when Windows is configured correctly | Medium |
| Driver, game, or multi-monitor configuration issue | Desktop reaches 144Hz but one game does not, or refresh rate changes after sleep | Medium |
Diagnose Step by Step
1. Confirm the active refresh rate in Windows
Open Settings > System > Display > Advanced display. Select the affected monitor from the drop-down menu if more than one display is connected. Check the value beside Choose a refresh rate. Select 144 Hz if it is listed. Windows may display values such as 143.97Hz, 143.98Hz, or 144Hz; these are normal equivalents for practical purposes.
Also check the line labeled Display information. It should show the monitor’s native resolution and the intended refresh rate. If the menu only offers 60Hz, do not force a random custom resolution yet. Continue with the cable, port, and GPU checks first.
2. Check the monitor’s OSD information page
Press the monitor’s physical menu button or joystick, then look for a page named Information, Display Info, Input Information, or Status. The wording varies by manufacturer. Confirm the reported input resolution and vertical frequency. For example, a 1920 × 1080 monitor should report 1920 × 1080 at approximately 144Hz when configured correctly.
If Windows says 144Hz but the monitor OSD says 60Hz, the problem is usually the cable, selected input, adapter, dock, or graphics driver output settings.
3. Verify the cable and both connection ports
Trace the cable from the graphics card to the monitor. For a desktop gaming PC, connect the monitor directly to the dedicated graphics card, not to the motherboard video output. DisplayPort is generally the simplest connection for 144Hz PC gaming. HDMI can also support 144Hz, but support depends on the monitor’s HDMI version, native resolution, and specific input port.
Remove any HDMI splitter, KVM switch, USB-C dock, capture device, extender, AV receiver, or passive video adapter during our research. These devices can negotiate a lower display mode even when the cable and monitor are otherwise capable.
4. Check the GPU control panel
For NVIDIA, right-click the desktop and open NVIDIA Control Panel > Display > Change resolution. Select the monitor, then choose its native resolution from the PC section of the resolution list, not a similarly named resolution under Ultra HD, HD, SD. Set Refresh rate to 144Hz.
For AMD, open AMD Software: Adrenalin Edition > Settings > Display. Verify the display specifications and disable any custom resolution temporarily. For Intel graphics, open Intel Graphics Software > Display and select the native resolution and highest supported refresh rate.
5. Test with one display and one known-good path
Shut down the PC, disconnect secondary monitors, and leave only the 144Hz display attached directly to the GPU. Boot Windows and check Advanced display again. If 144Hz now appears, reconnect devices one at a time. This isolates bandwidth, dock, driver, and display-detection problems without changing permanent settings.
6. Check individual game settings
If Windows is already at 144Hz but a game feels locked to 60Hz, open that game’s video or display settings. Use Exclusive Fullscreen where available, choose the monitor’s native resolution, and set refresh rate to 144Hz. Disable a 60 FPS frame limiter and check V-Sync settings. Borderless windowed mode normally follows the Windows desktop refresh rate, while exclusive fullscreen titles may use their own selected frequency.
Fixes by Cause
Windows is configured for a lower refresh rate
What causes it: Windows often defaults to 60Hz after a new monitor connection, driver reset, major update, cable change, or display-profile problem.
How to check: Go to Settings > System > Display > Advanced display and inspect Choose a refresh rate.
What to do: Select 144Hz, then click Keep changes when prompted. If using Windows 11, also review Settings > System > Display > Graphics > Default graphics settings. Turn off Dynamic refresh rate temporarily if it is available and troubleshooting is inconclusive.
How to undo: Return to Advanced display and choose the previous refresh rate, such as 60Hz or 120Hz. Re-enable Dynamic refresh rate in Default graphics settings if you had used it before.
The cable or selected port cannot carry the required signal
What causes it: Older HDMI cables, damaged cables, non-certified cables, limited monitor HDMI ports, and certain adapters can prevent 144Hz at the monitor’s native resolution. A cable may work perfectly at 60Hz while failing at higher bandwidth.
How to check: Inspect the monitor manual or OSD input information for supported modes on each port. Test a direct DisplayPort-to-DisplayPort connection if both the GPU and monitor have DisplayPort. Avoid adapters during the test.
What to do: Replace the cable with a properly rated, short direct cable. Use DisplayPort when possible. If HDMI is required, use the monitor input specifically documented for high refresh rates and connect directly to the GPU. Fully reseat both ends; a partially inserted DisplayPort connector can cause intermittent detection.
How to undo: Reconnect the prior cable or device path. No software settings are permanently changed by cable testing.
NVIDIA, AMD, or Intel output settings are limiting refresh rate
What causes it: The GPU driver can select a TV-style timing mode, non-native resolution, excessive color depth, or a custom resolution that does not expose 144Hz.
How to check: In NVIDIA Control Panel, open Display > Change resolution. Look for the monitor’s native resolution under the PC heading. Check output color depth and output color format near the bottom of the window.
What to do: Select the native PC resolution and 144Hz. If 144Hz is unavailable with HDR or 10-bit output enabled, temporarily set color depth to 8 bpc and use RGB output. In Windows, test by turning off Settings > System > Display > HDR, then check whether 144Hz returns. Update the graphics driver using the GPU manufacturer’s official installer if the display is detected incorrectly.
How to undo: Restore your former HDR state, color depth, and color format after testing. In NVIDIA Control Panel, select Use default color settings to return to driver defaults.
The monitor OSD is restricting the input mode
What causes it: Some monitors include settings such as HDMI compatibility mode, DisplayPort version selection, overclock mode, console mode, or input version controls that alter available refresh rates.
How to check: Open the monitor OSD and inspect sections named Input, System, Gaming, or Display. Look for DisplayPort 1.1/1.2/1.4 options, HDMI mode, FreeSync or Adaptive-Sync, and overclock settings.
What to do: Set the input to the newer supported standard rather than a compatibility mode. Enable the monitor’s 144Hz or overclock mode only if its documentation identifies that mode as necessary. Use the OSD’s Reset All or Factory Reset option only after noting your current picture settings.
How to undo: Restore the recorded OSD settings, or run the same factory reset again and configure only the settings you need.
A driver or display profile is corrupted
What causes it: Failed driver updates, sleep/wake glitches, and stale monitor detection data can leave Windows with incomplete supported-mode information.
How to check: Press Win + Ctrl + Shift + B. The screen should briefly flicker as Windows resets the graphics driver. Then recheck Advanced display. Open Device Manager > Monitors and confirm the monitor is detected rather than listed only as Generic PnP Monitor.
What to do: Restart the PC, then install the latest stable GPU driver. If the issue remains, in Device Manager expand Monitors, right-click the affected monitor, choose Uninstall device, and restart. Windows will redetect it. If the monitor manufacturer provides an INF driver, install it through Device Manager > Update driver > Browse my computer for drivers.
How to undo: In Device Manager, use Properties > Driver > Roll Back Driver for the GPU if the problem started immediately after an update. Remove a manually installed monitor INF by uninstalling that monitor device and restarting.
When to Replace or Reinstall
Replace the cable first if 144Hz works only when the cable is bent, held in a certain position, or swapped with another cable. Cables are inexpensive failure points, and replacement is more sensible than extended troubleshooting.
Reinstall or roll back the graphics driver when 144Hz vanished immediately after a driver update, Windows update, crash, or sleep-resume issue. Use a normal clean installation option from the GPU driver installer before considering more aggressive cleanup tools.
Consider monitor service or replacement when the display’s own OSD reports a lower maximum refresh rate on every tested PC, with multiple direct cables and supported ports. Also investigate replacement if the monitor flickers, loses signal, shows artifacts, or cannot maintain 144Hz while another compatible monitor works normally on the same GPU and cable.
FAQ
Why does my 144Hz monitor only show 60Hz in Windows?
The usual reasons are a lower-bandwidth cable or port, a connection through a dock or adapter, or Windows being set to 60Hz. Check Advanced display first, then test a direct DisplayPort connection from the graphics card to the monitor.
Can HDMI run a monitor at 144Hz?
Yes, but it depends on the monitor’s resolution, HDMI implementation, and individual input port. Some monitors support 144Hz over DisplayPort but only 60Hz or 120Hz over HDMI. Check the monitor specifications and use the correct port.
Why is 144Hz available on the desktop but not in my game?
The game may have its own refresh-rate selector, be using a different resolution, or be running in exclusive fullscreen with a 60Hz mode selected. Set the game to native resolution and 144Hz, then check its frame limiter and V-Sync options.
Is 143.97Hz the same as 144Hz?
For normal use, yes. Windows and GPU drivers may show slightly different timing values because of display standards and signal timing. A reading around 143.97Hz or 143.98Hz indicates that the monitor is operating in its intended 144Hz mode.
