A 210Hz monitor showing 60Hz is usually running a lower Windows mode, a resolution/input combination that does not expose 210Hz, or a connection path that cannot negotiate the advertised mode. It is not possible to identify the exact cause without your monitor model, resolution, GPU and ports. Start with Settings > System > Display > Advanced display, then verify the monitor manual, GPU settings and cable path in that order.
What a 60Hz reading actually tells you
Refresh rate is the number of times the display redraws each second. At 60Hz, Windows is sending a 60-refresh-per-second mode; a 210Hz panel can still operate at that lower mode when Windows, the graphics driver or the connection selects it. The number printed on the monitor box is normally a maximum for at least one specific resolution and input, not a promise that every resolution, port or device combination will offer 210Hz.
The first useful distinction is whether 210Hz is missing everywhere or only in one application. If Windows itself lists only 60Hz, investigate the selected display, resolution, monitor input, cable, adapter, port and driver control panel. If Windows is set above 60Hz but one game reports 60Hz, investigate that game’s display mode and Windows 11 Dynamic Refresh Rate instead of immediately replacing hardware.

1. Check the selected display and Windows mode
- Open Settings > System > Display > Advanced display.
- If more than one screen is connected, select the monitor that is showing 60Hz. Do not assume the first display in the list is the affected one.
- Record the current display resolution and the refresh-rate value shown for that display.
- Open the refresh-rate menu and choose the highest rate Windows offers at the current resolution. Apply the change and confirm it when Windows asks.
- Wait for the screen to redraw, then reopen Advanced display to verify that the new value persisted.
Microsoft explains that this list is generated from the display’s reported capabilities, so a missing 210Hz entry is evidence that the current display path is not exposing that mode; it is not proof that the panel itself is defective. See Microsoft’s Windows refresh-rate instructions.
Understand the asterisk and resolution warning
Windows can show a refresh rate with an asterisk when that rate does not support the currently selected resolution. Microsoft warns that choosing such an entry changes the resolution to achieve the selected refresh rate. Check the resolution again after applying any starred option; a high number paired with an unexpectedly lower resolution is a different mode from 210Hz at your intended resolution.
If 120Hz, 144Hz, 165Hz or another value appears but 210Hz does not, select the highest listed value first and continue with the model and connection checks below. Do not infer that the monitor is limited to the value you happen to see until you have confirmed the input and resolution in its specification table.

2. Confirm what your exact monitor model supports
Find the complete model number on the rear label, the monitor’s on-screen display information page or your purchase record. Then open the manufacturer’s manual or specification table and look for a timing table that separates resolution, input and refresh rate.
Record these items before troubleshooting further:
- The exact native and alternative resolutions you intend to use.
- The maximum refresh rate at each resolution.
- Which physical inputs support the maximum rate.
- Whether a port is driven through a special mode, overclock setting or menu option.
- Whether the manual describes the maximum as a factory mode, an overclocked mode or an “up to” value.
“210Hz” alone does not establish that 210Hz is available at every resolution or through every HDMI, DisplayPort, USB-C or adapter path. The model-specific answer cannot be determined from the title alone. Follow the manual’s table for your particular monitor and the output specifications for your graphics device; do not apply a universal HDMI-versus-DisplayPort rule.
Check the monitor’s own input and mode menus
Use the monitor’s physical buttons or joystick to open its on-screen display. Confirm that the active input is the socket connected to the computer, and look for an information page that reports the incoming resolution and refresh rate. Some displays have an input-version, high-bandwidth or overclock option; only enable a setting when the manual describes it and explains its effect. If the OSD itself reports a 60Hz signal, Windows is not currently delivering a faster mode to that input.

3. Verify the graphics-driver control panel
Windows is the primary place to select the refresh rate, but the GPU vendor’s control panel can expose a different list or reveal that the driver is using another display mode. Use the panel that matches the GPU connected to the monitor.
NVIDIA graphics
- Right-click the desktop and open NVIDIA Control Panel.
- Under Display, choose Change resolution.
- Select the affected monitor in the display selector.
- Choose a refresh rate that is listed for the desired resolution, then select Apply.
- Return to Windows Advanced display and confirm the resulting mode.
NVIDIA documents this workflow in its screen-refresh-rate help. Its Change Resolution guidance also notes that bandwidth limits can remove some color-depth choices and suggests trying a lower resolution or refresh rate when bandwidth affects the available options. That is a mode-constraint clue, not proof that bandwidth is the cause of your particular 60Hz cap.
AMD graphics
AMD says some displays may not have their maximum refresh rate selected by default. Follow the Windows refresh-rate procedure applicable to your Radeon software and Windows version, then check the resulting mode in Advanced display. The steps and screenshots are in AMD’s display brightness, resolution and refresh-rate FAQ. If the AMD panel and Windows offer different values, use the exact resolution and input combination documented by your monitor manual as the reference.

4. Isolate the cable, adapter, dock and port
A connection problem can make a high-rate mode disappear even when the panel and GPU can support it. Change one physical element at a time so you can tell which component affects the result.
- Turn off or put the computer and monitor in standby, then reseat the cable at both ends. Make sure it is fully inserted and connected to the intended GPU output rather than a motherboard video socket when a discrete GPU is installed.
- Temporarily remove docks, dongles, KVMs, converters and extension adapters. Connect the monitor directly to the computer’s output.
- Try another output on the graphics card or laptop, if one is available and documented as compatible with the monitor’s mode.
- Test with another known-good cable. The replacement must meet the connector and bandwidth requirements specified by both the monitor and the graphics device; a cable swap is a diagnostic step, not a guarantee that any particular cable type unlocks 210Hz.
- If possible, connect the monitor to another computer that supports the required resolution and refresh rate. Observe whether the 210Hz option follows the monitor, remains with the original computer, or disappears only through one adapter or port.
These checks follow Microsoft’s external-monitor troubleshooting sequence: secure the cable, disconnect accessories, try another cable or port and test another system. The full procedure is in Microsoft’s external-monitor connection guide.

| Observation | Most useful interpretation | Next action |
|---|---|---|
| 210Hz appears after bypassing a dock or adapter | The intermediate device or its negotiated mode was restricting the display signal. | Use a direct connection or a replacement adapter whose specifications explicitly cover the monitor’s resolution and refresh rate. |
| Another cable restores higher rates | The original cable, its condition or its signal integrity was limiting the available modes. | Keep the cable that works and verify it meets both devices’ documented requirements. |
| Only one GPU output exposes 210Hz | The ports may have different capabilities, or one port may be faulty. | Use the working output and consult the GPU and monitor manuals for port-specific limits. |
| The monitor is 60Hz on every tested computer | The limitation follows the display, its input selection or its configuration. | Recheck the model’s timing table and OSD input settings; contact the monitor manufacturer if the documented mode is still absent. |
| 210Hz works on another computer but not the original | The original computer’s port, driver, adapter, cable or selected mode is implicated. | Repeat the direct-connection test and update or reinstall the appropriate graphics driver using the computer or GPU manufacturer’s instructions. |
5. Check Windows 11 Dynamic Refresh Rate when only games are capped
Dynamic Refresh Rate (DRR) is a Windows 11 feature that automatically changes refresh rate according to activity. Microsoft says it requires a variable-refresh-rate-capable display and at least 120Hz support, and warns that DRR can limit the maximum refresh rate in some games.

DRR is therefore a targeted check, not a universal explanation for a desktop that is stuck at 60Hz. First verify that Windows Advanced display can select the desired rate. If the desktop uses a high rate but a Windows 11 game falls back to 60Hz, temporarily disable DRR in the display settings, launch the game again and check its in-game display mode. If the game’s cap disappears, you have identified a software interaction; if it remains, inspect the game’s own resolution and refresh-rate menu.
6. Separate a Windows-wide cap from a game-only cap
When Windows itself shows only 60Hz
- Confirm that Advanced display is pointed at the 210Hz monitor, not another screen.
- Check the monitor manual for the selected resolution and active input.
- Inspect the monitor OSD for the incoming signal and any required input-version or high-bandwidth setting.
- Bypass adapters and docks, test another cable and try another GPU output.
- Check the matching NVIDIA or AMD control panel for a different list of supported modes.
When Windows shows a high rate but a game shows 60Hz
- Set the game’s display mode to the same resolution and refresh rate that Windows is using.
- Check whether the game has its own frame-rate limit; a frame-rate cap is not the same thing as a monitor refresh-rate setting.
- On Windows 11, test with DRR disabled if the problem occurs only in particular games.
- Use borderless or exclusive-fullscreen options consistently while testing, because a game can use a different display path in each mode.
Do not describe a game-only cap as evidence that the monitor cannot run 210Hz. Establish the operating-system mode first, then troubleshoot the application’s setting.
7. What not to do first
Do not create arbitrary custom timings
Custom resolutions and timings can produce a blank screen, an out-of-range warning or an unstable signal. They are not a routine fix for a mode that should already be listed by Windows. Confirm the monitor’s supported timings in its manual and follow the monitor or GPU manufacturer’s instructions before attempting any custom mode. If a custom mode causes loss of picture, wait for Windows to revert, use another display or start in a recovery mode, then remove the unsupported setting.

One-click scans. No signup required.
Do not buy a cable without checking both ends
A generic replacement cable may have the wrong connector, may pass through an adapter that imposes its own limit, or may not satisfy the documented requirements of the monitor and GPU. Use a known-good cable as an isolation test, and select a permanent replacement only after checking those specifications.
Do not assume the printed 210Hz value is available at native resolution
Some specifications advertise a maximum that applies only to one resolution, one input or an optional overclock setting. If 210Hz appears only after reducing resolution, that is a supported mode distinction to record, not proof that Windows is malfunctioning.
8. A compact decision checklist
- Identify: Write down the monitor’s full model number, active input, target resolution, GPU model and cable or adapter path.
- Inspect Windows: In Settings > System > Display > Advanced display, select the affected monitor and note every offered refresh rate.
- Validate the mode: Compare the desired resolution and input with the monitor’s official timing table. Check for an asterisk or an automatic resolution change.
- Cross-check the driver: Use NVIDIA Control Panel’s Display > Change resolution or the AMD-supported Windows procedure, depending on your GPU.
- Isolate hardware: Reseat the cable, remove docks and adapters, try another cable, try another GPU port and test another computer.
- Target software: If only certain Windows 11 games are capped, test DRR and the game’s own display settings.
- Escalate with evidence: Contact the monitor or computer manufacturer with the exact model, resolution, input, screenshots of the available modes, OSD signal information and the results of your cable and second-system tests.
After these checks, you should know whether the 60Hz value is simply the selected Windows mode, an unsupported resolution/input combination, a connection-path limitation, a game or DRR interaction, or a problem that follows the monitor or computer. That evidence is more useful to support than a generic request to “unlock 210Hz,” because it identifies the component and mode that actually fail.
