How To See Refresh Rate Of Monitor: Complete Windows, MacOS, And Hardware Guide

Finding your monitor's actual refresh rate requires navigating to your operating system's advanced display settings, checking the hardware On-Screen Display (OSD), or utilizing online browser diagnostics like TestUFO. Verifying this value ensures your panel operates at its native maximum frequency—whether 60 Hz, 144 Hz, 240 Hz, or higher—rather than defaulting to a lower standard fallback. Confirming matching output frequencies across OS settings, graphics control panels, and display cables eliminates stutter and maximizes panel motion clarity.

Pre-Check Setup & Display Pipeline Hardware Requirements

Before auditing your monitor's actual refresh rate, you must understand the hardware pipeline that delivers frame signals from the graphics processing unit (GPU) to the liquid crystal panel. A monitor cannot refresh faster than the maximum frequency transmitted across the physical display interface cable. Furthermore, operating system display drivers negotiate maximum available resolutions and frame rates through Extended Display Identification Data (EDID) handshake protocols upon system boot. If any link in this transmission chain lacks sufficient signal bandwidth, the operating system will lock the display output to a standard safety threshold—frequently 60 Hz.

Verify that your physical setup meets all core technical requirements prior to checking or modifying your display parameters.

• Essential Gear and Hardware Interfaces:
  
  
  • Display panel with verified manufacturer support for high refresh rates (100 Hz, 144 Hz, 165 Hz, 240 Hz, 360 Hz, or 540 Hz).
  • Bandwidth-compliant video cable (DisplayPort 1.4/2.1 or High-Speed/Ultra-High-Speed HDMI 2.0/2.1 cable).
  • Dedicated Graphics Processing Unit (Nvidia GeForce GTX/RTX, AMD Radeon RX, or Intel Arc series) with updated display output ports.
• Mandatory Prerequisite Knowledge and Software Standards:
  
  
  • Installed proprietary graphics drivers (Nvidia Game Ready / Studio Driver, AMD Software: Adrenalin Edition, or Intel Graphics Command Center).
  • Administrative access to operating system display options and control panels.
  • Awareness of display panel native resolution versus scaling modes (e.g., 2560x1440 at 144 Hz vs 3840x2160 at 60 Hz).
• Estimated Duration and Resource Benchmarks:
  
  
  • Configuration and auditing time: 1 to 3 minutes.
  • Financial cost: $0 (utilizes built-in operating system tools and monitor hardware controls).

Step-by-Step Verification Protocols for Windows, macOS, and Linux

Step 1: Auditing Windows 11 and Windows 10 Advanced Display Settings

The native Windows Settings application provides the primary direct interface to inspect active video output parameters, including vertical scan frequency measured in Hertz (Hz).

1. Press the shortcut keys Windows Key + I simultaneously to open the system Settings panel.
2. Select System from the left-hand navigation menu, then click Display on the main panel canvas.
3. Scroll down the display properties page to locate the Related settings section and click on Advanced display (or Advanced display settings in Windows 10).
4. Identify the panel selection dropdown at the top if multiple monitors are connected. Choose the specific target display.
5. Review the Display information block to see the active Desktop mode and Active signal mode. The current refresh rate will be explicitly listed in Hertz next to the operational resolution (for example, 2560 x 1440, 144.00 Hz).
6. To modify or elevate the refresh rate, locate the Choose a refresh rate drop-down selector at the bottom of the window, click it, and select the highest supported frequency value available.

Pro-Tip: If your 144 Hz or 240 Hz display only displays a maximum option of 60 Hz inside Windows settings, your monitor is likely connected via an older revision HDMI cable or plugged into the motherboard's integrated graphics port rather than the discrete graphics card.

Step 2: Identifying Refresh Rate on macOS Ventura, Sonoma, and Newer

Apple's macOS manages display timing natively inside system settings, though specific high-refresh parameters require explicit setting changes when using external gaming panels.

1. Click the Apple Icon in the extreme top-left corner of the primary menu bar and select System Settings (or System Preferences on older macOS versions).
2. Scroll down the left sidebar menu and click Displays.
3. Select your external monitor thumbnail displayed at the top of the window canvas.
4. Locate the Refresh Rate drop-down menu situated on the main configuration panel.
5. Read the active selection. If the panel supports Variable Refresh Rate technology or Apple ProMotion, options such as 60 Hertz, 120 Hertz, or 144 Hertz will be selectable alongside ProMotion.
6. Select your preferred maximum fixed value or dynamic rate.

Warning: Operating macOS displays in mirrored mode limits all connected screens to the maximum refresh rate supported by the slowest active monitor. Always set external high-refresh monitors to operate as an Extended Display to unlock higher refresh rate toggles.

Step 3: Querying GPU Control Panels (NVIDIA Control Panel & AMD Adrenalin)

Graphics card management software bypasses standard OS display abstraction layers and reads raw EDID parameters directly from the monitor's display controller board.

1. Right-click on an empty space on your desktop canvas and launch NVIDIA Control Panel or AMD Software: Adrenalin Edition.
2. For NVIDIA Graphics Cards:
   
   
   • Expand the Display node in the left-hand navigation tree.
   • Click on Change resolution.
   • Select your target display monitor icon.
   • Locate the Refresh rate drop-down box located on the right side of the screen adjacent to the resolution selection box.
   • Confirm the highlighted Hertz value or select a higher frequency step and click Apply.
3. For AMD Radeon Graphics Cards:
   
   
   • Click the Settings (Gear Icon) in the top right, then select the Display tab.
   • View the active display card details. Locate the Current Refresh Rate section under the display specs panel.
   • Alternatively, modify display modes inside Global Display Settings.

Step 4: Reading Hardware On-Screen Display (OSD) and Web Diagnostic Tools

Software settings can occasionally misreport active signal output if video scaling occurs on the GPU. Checking the physical monitor hardware status provides direct verification of real-time panel timing.

1. Press the physical menu button or tactile directional joystick located on the back or bottom bezel of your monitor frame.
2. Navigate to the Information, Status, or System tab using the monitor's internal On-Screen Display (OSD) menu interface.
3. Read the hardware status block. Look for the lines labeled Current Resolution and Vertical Frequency or Refresh Rate. This value confirms the exact live signal received by the monitor controller board.
4. Open a modern desktop web browser (such as Chrome, Edge, or Firefox) and navigate to testufo.com.
5. Allow the automated visual refresh rate test to run without moving your browser window or mouse cursor.
6. Observe the primary readout banner at the top of the browser viewport. The tool will calculate real-time frame rates and display your exact active refresh rate along with pixel movement sync status.

Display Cable & Port Bandwidth Capabilities Matrix

The maximum refresh rate visible and selectable in your operating system depends heavily on display interface bandwidth limitations. The following matrix outlines maximum achievable refresh rates across standard display resolutions without relying on aggressive display color subsampling.

Troubleshooting Common Refresh Rate Bottlenecks and Display Failures

Panel Locked at 60 Hz on a High-Refresh Rated Monitor

• Root Cause: The display cable is connected to the motherboard video output (utilizing integrated CPU graphics) rather than the discrete GPU, or an obsolete HDMI cable (HDMI 1.2/1.3) with insufficient physical bandwidth capacity is being used.
• Actionable Fix: Turn off the PC and trace the display cable from the back of the monitor. Plug the cable directly into the horizontal expansion slots of the dedicated graphics card. If the issue persists, replace the existing cable with a certified VESA DisplayPort 1.4 cable or Ultra High Speed 48Gbps HDMI 2.1 cable.

Screen Flickers, Goes Black, or Displays No Signal Above 60 Hz

• Root Cause: Signal degradation caused by unshielded cables, excessive cable length exceeding specs (over 3 meters/10 feet without active signal boosting), or unstable overclock settings within the monitor's built-in OSD menu.
• Actionable Fix: Access the monitor OSD menu using physical frame buttons, navigate to display settings, and disable internal panel "Overclock" features. Revert display settings to default values. If using custom display extensions or passive adapter dongles (e.g., USB-C to DisplayPort), remove them and establish a direct connection using a high-grade cable under 2 meters in length.

Missing Native Refresh Rates in Operating System Display Settings

• Root Cause: Generic Windows PnP (Plug and Play) driver overrides corrupting Extended Display Identification Data (EDID) recognition, or outdated GPU display pipeline graphics drivers.
• Actionable Fix: Download and install the specific INF driver package directly from your monitor manufacturer's support site. Open Device Manager, expand Monitors, right-click Generic PnP Monitor, select Update driver, choose Browse my computer for drivers, and manually point to the extracted manufacturer driver folder. Following this, perform a clean installation of your GPU drivers using Display Driver Uninstaller (DDU) software.

Frequently Asked Questions

Why does my 144 Hz monitor only show 60 Hz in Windows settings?

Windows defaults newly connected displays to a standard 60 Hz signal profile to guarantee signal compatibility. You must manually open Advanced Display Settings or your GPU control panel and change the refresh rate dropdown menu from 60 Hz to 144 Hz after connecting the display for the first time.

Is frame rate (FPS) identical to monitor refresh rate (Hz)?

No, frame rate (FPS) measures how many render frames your graphics card produces per second, whereas refresh rate (Hz) measures how many times per second your physical monitor redraws the screen image. If your GPU outputs 200 FPS on a 60 Hz panel, you will only visually perceive 60 distinct frames per second.

How do I check if dynamic Variable Refresh Rate (G-Sync or FreeSync) is active?

You can confirm Variable Refresh Rate engagement by opening your monitor's internal physical On-Screen Display (OSD) menu while running a 3D application or video game. If G-Sync or FreeSync is active, the real-time Hz readout in the OSD menu will fluctuate dynamically to mirror your in-game FPS counter.

Can I see my monitor's refresh rate without powering on a PC?

Yes, you can verify your monitor's hardware capabilities without a booted operating system by reading the label sticker on the back casing of the panel or accessing the hardware OSD menu built into the panel firmware when powered via a standalone signal source.

Maximize Your Display Hardware Performance

Verifying and locking in your monitor's highest supported refresh rate ensures you experience fluid motion, reduced input latency, and maximum visual clarity across high-speed workloads and interactive applications. If you continue encountering frame delivery limitations after configuring your operating system and hardware settings, perform a complete driver cleanup and upgrade to certified high-bandwidth DisplayPort or HDMI cables to fully unlock your monitor's underlying hardware capabilities.
