To run a monitor at 144Hz, 165Hz, 240Hz or another high refresh rate, every part of the signal path must support the same resolution and refresh target: the monitor input, cable, GPU output, driver and Windows display mode. Connect the monitor directly to the discrete GPU, select the intended refresh rate under Settings > System > Display > Advanced display, enable Adaptive-Sync, FreeSync or VRR in the monitor’s on-screen display, and then turn on G-SYNC or FreeSync in your GPU software.
If Windows shows only 60Hz, the system is normally receiving a 60Hz capability report from the selected input, cable, resolution, driver or monitor mode. Work through the setup in order rather than forcing a refresh rate that the chosen resolution and connection cannot sustain.
What must support the target refresh rate
A high-refresh setup is limited by its weakest link. A monitor advertised as 240Hz may reach that rate only at particular resolutions and through particular inputs. A graphics card may render enough frames but still be connected through an output, cable or adapter that exposes only lower modes. Windows lists the modes reported by the display, so a missing option usually indicates a capability or configuration problem rather than a hidden Windows switch.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- Monitor: Check the manual for the maximum refresh rate at your chosen resolution, the variable-refresh-rate range, and which inputs support it.
- GPU: Confirm that the graphics card output supports the monitor’s resolution, refresh target and VRR method. A discrete GPU should be used when the PC has one.
- Port and cable: Match the monitor input and cable to the documented DisplayPort Adaptive-Sync or HDMI VRR capability. Passive adapters, docks and older cables can remove high-refresh modes.
- Driver: Install the current graphics driver supplied for your GPU. Driver control panels expose VRR options only when the display and driver report a compatible path.
- Operating system: Windows must be able to read the display’s supported modes. Windows 11 also has separate controls for windowed-game optimizations and Dynamic Refresh Rate.
Use the monitor manual and GPU specifications as the authority for the exact combination. The highest number printed on a product box is not guaranteed at every resolution, color mode or input.

Connect the monitor to the correct GPU output
Use the discrete GPU, not the motherboard video output
On a desktop with a separate graphics card, plug the monitor cable into the graphics card’s output panel. Motherboard HDMI or DisplayPort connectors may be driven by the processor’s integrated graphics and can have different limits. Use a motherboard output only when its specifications explicitly support the resolution, refresh rate and VRR mode you want.
Connect one monitor directly to one GPU output while troubleshooting. Remove KVM switches, docking stations, signal converters and daisy-chain devices until the target mode works. Each intermediate device must pass the same resolution, refresh and VRR capabilities; otherwise Windows may expose only conservative modes.
Choose DisplayPort or HDMI based on the documented mode
There is no universal rule that DisplayPort is always faster. The correct choice is the port and cable combination that the monitor and GPU specify for your target mode. AMD documents FreeSync through DisplayPort Adaptive-Sync and HDMI VRR. NVIDIA documents HDMI 2.1 VRR for supported GeForce GTX 16-series and RTX 20-series-and-newer combinations, while individual monitor support still determines whether that path works.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →If the manual lists a high-refresh mode only on DisplayPort, use DisplayPort. If it lists HDMI 2.1 VRR for the desired mode, use a cable and GPU output that support that implementation. Do not assume an HDMI cable marked for a different device will provide the same capability on a PC.
Enable the monitor’s own gaming settings
Turn on Adaptive-Sync, FreeSync or VRR
Open the monitor’s on-screen display with its joystick or buttons. Look under Gaming, Display, Adaptive-Sync, FreeSync or Variable Refresh Rate and enable the setting. Names and locations vary by model. Save the setting, then select the input that is physically connected to the GPU.

- Multi-functional Support: The 8K DisplayPort cable supports video resolutions up to 8K@60Hz and transmits HD audio and video from computer to display, ideal for video streaming and gaming. It is also backward compatible with DP 1.3/1.2/1.1
Some monitors expose additional input modes such as DisplayPort 1.2, DisplayPort 1.4 or an “enhanced” HDMI mode. Select the version required by the manual for the desired resolution and refresh rate. AMD’s configuration guidance also advises disabling Anti-Blur where that option exists, because blur-reduction strobing and variable refresh commonly cannot operate together.
Set the monitor to its intended resolution
Use the monitor’s native resolution when possible. If the monitor offers several refresh ranges, the on-screen display may show a range rather than a single value. Keep a note of the supported range so you can later decide whether to cap game frame rates inside it.
Set the refresh rate in Windows
After the cable and monitor settings are correct, choose the operating-system mode. Microsoft says the refresh-rate list is based on what the display reports, and an asterisk marks a rate that does not support the current resolution.
- Open Start > Settings > System > Display.
- If several displays are connected, select the monitor you are configuring.
- Open Advanced display.
- Use the display selector at the top if necessary, then open Choose a refresh rate.
- Select the highest rate that is supported at the resolution you intend to use. Avoid an entry with an asterisk unless you deliberately accept the resolution change it describes.
- Accept the confirmation prompt and check that the displayed resolution remains correct.
Windows may briefly blank the screen while applying the mode. If the picture does not return, wait for the automatic rollback or use the keyboard to revert. A rate such as 165Hz can appear only after the correct input, driver and monitor OSD mode are active.
Understand what the refresh number means
Refresh rate is how often the display can update each second; Microsoft uses 60 updates per second as the illustrative definition of 60Hz. It is not the same as the game’s frame rate. If the GPU renders fewer frames than the selected refresh rate, the monitor cannot display a new frame on every refresh. Variable refresh rate helps synchronize updates within the display’s supported range, but it cannot create frames that the GPU did not render.

Enable VRR for your GPU
Variable refresh must often be enabled in two places: the monitor OSD and the GPU control software. Use the branch for your graphics platform.
| GPU platform | Control-panel path | Required monitor setting | Compatibility details |
|---|---|---|---|
| NVIDIA | NVIDIA Control Panel > Display > Set up G-SYNC; select “Enable G-SYNC, G-SYNC Compatible,” then Apply | Enable the monitor’s Adaptive-Sync or VRR option; choose G-SYNC/G-SYNC Compatible under Monitor Technology when that control is available | NVIDIA says G-SYNC Compatible displays require a Pascal-class or newer GPU. For HDMI, NVIDIA documents HDMI 2.1 VRR on supported GeForce GTX 16-series and RTX 20-series-and-newer combinations. |
| AMD | AMD Software or Radeon Settings > Display; confirm AMD FreeSync is On | Enable FreeSync or Adaptive-Sync in the monitor OSD; AMD also advises disabling Anti-Blur where present and setting DisplayPort to 1.2 or higher when applicable | AMD states that FreeSync can be delivered through DisplayPort Adaptive-Sync or HDMI VRR on certified, compatible displays. |
NVIDIA: configure G-SYNC or G-SYNC Compatible
- Install or update the NVIDIA graphics driver.
- Right-click the desktop and open NVIDIA Control Panel.
- Choose Display > Set up G-SYNC.
- Select Enable G-SYNC, G-SYNC Compatible.
- Choose whether it should apply to full-screen mode or full-screen and windowed mode. If you play borderless games, select the option that includes windowed applications.
- Select the monitor, apply the change, and open the display-specific settings if the control panel offers them.
- Set Monitor Technology to G-SYNC or G-SYNC Compatible when that option is required for the selected display.
If the G-SYNC page is missing, first verify that the monitor’s VRR option is on and that Windows is using the GPU-connected input. A display can be capable of Adaptive-Sync while a particular GPU generation, port or cable combination is not validated for G-SYNC Compatible operation.
AMD: configure FreeSync
- Install the current Radeon graphics driver for the GPU or integrated graphics processor.
- Open AMD Software or Radeon Settings.
- Open the Display section.
- Find the monitor and set AMD FreeSync to On.
- Check that the monitor OSD still has FreeSync or Adaptive-Sync enabled.
AMD FreeSync requires a compatible Radeon GPU or APU and a compatible display implementation. If the toggle is absent, update the driver and confirm the monitor is connected directly to a supported output.
Configure games for smooth output
Keep the frame rate in the VRR range
Start a game and use its display or graphics menu to select the monitor’s native resolution and the desired refresh rate where the game offers that choice. Then verify the monitor OSD or GPU control panel reports the expected refresh or VRR state.
If the GPU regularly renders more frames per second than the display can refresh, AMD recommends enabling V-Sync or applying an in-game frame cap for tear-free output. Set a cap below the monitor’s maximum refresh rate when necessary to leave room for synchronization. The exact cap depends on the monitor’s documented range and the game’s frame-time behavior; do not assume that one value suits every display.

Choose the correct presentation mode
Exclusive full-screen, borderless and windowed modes can take different rendering paths. If VRR works in full-screen but not in a borderless game, enable the GPU control panel’s windowed option where available and use Windows 11’s windowed-game optimization described below. If a game offers its own V-Sync, frame limiter or refresh selector, keep those settings consistent with the GPU control panel rather than enabling conflicting limits in several places.
Windows 11 options for windowed and borderless games
Windows 11 includes an operating-system feature for DirectX 10 and DirectX 11 games running in windowed or borderless windowed modes. Microsoft says it can improve gaming performance and enable modern presentation features, including VRR on supported displays.
- Open Settings > System > Display > Graphics.
- Find Optimizations for windowed games and enable it.
- Restart the game so Windows can apply the presentation change.
This option does not make an incompatible monitor or GPU support VRR. It applies only to the supported DirectX 10 and DirectX 11 windowed or borderless paths, so a game using a different rendering API may not change behavior.
Check Dynamic Refresh Rate
Windows 11 Dynamic Refresh Rate (DRR) requires a VRR-capable display and at least 120Hz. It can lower a game’s maximum rate when the game is not designed for VRR. If a high-refresh monitor unexpectedly runs a game below its selected maximum, open the display’s advanced settings and disable DRR for that display, then test again. DRR is separate from the monitor’s VRR switch and from the game’s own frame limiter.
Troubleshoot a monitor stuck at 60Hz
Only 60Hz appears in Advanced display
- Confirm the monitor is selected in Settings > System > Display > Advanced display, especially when multiple screens are attached.
- Check that the cable is plugged into the discrete GPU rather than the motherboard.
- Try the monitor input documented for the high-refresh mode. A display can have different limits on different inputs.
- Remove adapters, docks, KVMs and converters and connect directly.
- Open the monitor OSD and enable the required Adaptive-Sync, enhanced-input or DisplayPort mode.
- Install the current GPU driver and restart Windows.
- Set the monitor to its supported resolution before choosing the refresh rate. Microsoft notes that some rate choices change resolution, and Windows exposes only modes reported by the display.
If the rate remains absent after these checks, the selected resolution, input and cable path probably cannot deliver it. Use the mode documented by the monitor manufacturer rather than forcing an unsupported custom mode.

The high rate lowers the resolution
Windows marks refresh choices that do not support the current resolution with an asterisk. Select a rate-resolution combination that the monitor supports together. If a high rate is available only at a lower resolution, decide whether smoother motion or native image detail matters more for that game, then keep the chosen pair consistent in Windows and in-game.
G-SYNC is not listed
- Confirm the GPU is Pascal-class or newer when using a G-SYNC Compatible display.
- Use the monitor input and connection type required by the display’s validated configuration; some setups require DisplayPort.
- Enable Adaptive-Sync or VRR in the monitor OSD.
- Open NVIDIA Control Panel and enable Set up G-SYNC, then apply the setting.
- Disconnect other displays temporarily if the control panel is applying the wrong monitor’s settings.
HDMI support depends on both ends of the link. NVIDIA’s documented HDMI 2.1 VRR combinations cover supported GeForce GTX 16-series and RTX 20-series-and-newer hardware, but the monitor must also implement the required mode.
FreeSync is not listed in AMD Software
- Verify that the monitor and Radeon GPU or APU are compatible with FreeSync.
- Enable FreeSync or Adaptive-Sync in the monitor OSD.
- Install the current Radeon driver and restart the PC.
- Open AMD Software > Display and check the monitor-specific FreeSync switch.
- Test a direct DisplayPort or supported HDMI connection without an adapter.
AMD supports FreeSync through DisplayPort Adaptive-Sync and HDMI VRR, but a monitor may certify only one of those paths or only a particular range.

Enable the GPU driver’s windowed-and-full-screen option where available. On Windows 11, turn on Settings > System > Display > Graphics > Optimizations for windowed games and restart the game. Test the game’s exclusive full-screen mode as a control case; if full-screen works and borderless does not, the limitation is the game’s presentation path rather than the monitor’s maximum refresh setting.
The screen flickers or loses signal
- Return to the last stable refresh-rate and resolution pair.
- Disable an unneeded adapter or dock and connect directly.
- Check the monitor manual for the required DisplayPort version or HDMI mode.
- Turn off Anti-Blur when using Adaptive-Sync on monitors that expose both settings.
- Test with VRR temporarily disabled in the OSD. If the signal becomes stable, re-enable VRR at a lower documented range and check the cable and input.
Do not treat a black screen as proof that the GPU is too slow. A link-training, input-mode or unsupported-resolution problem can produce the same symptom.
Compare setup choices before changing hardware
When two connection or configuration options are available, compare them on the factors that affect the actual gaming mode:
- Maximum refresh at the chosen resolution: Use the monitor manual’s mode table, not the headline refresh number.
- Connection standard and cable: Confirm the exact DisplayPort or HDMI implementation and whether an adapter is allowed.
- VRR technology and range: Check whether the path supports Adaptive-Sync, FreeSync or G-SYNC Compatible and the frame-rate range in which it operates.
- GPU compatibility: Match the required GPU generation and driver support, including NVIDIA’s Pascal-class requirement for G-SYNC Compatible displays.
- HDR and bit depth: Some displays expose different combinations of HDR, color depth and refresh rate. Choose a documented combination instead of assuming every feature runs at the maximum simultaneously.
- Game presentation mode: Verify whether the game is exclusive full-screen, borderless or windowed, because Windows and the driver can treat those paths differently.
A lower refresh at the monitor’s native resolution can be preferable to a higher refresh that forces an unwanted resolution or disables another feature. Make the decision from the mode table and the games you actually play.
Final verification checklist
- Read the monitor manual and GPU specifications for the target resolution, refresh rate, VRR range and required input.
- Connect the monitor directly to the discrete GPU with the documented cable standard.
- Enable Adaptive-Sync, FreeSync or VRR in the monitor OSD; disable Anti-Blur where AMD’s guidance applies.
- Set the required DisplayPort version or enhanced HDMI mode in the OSD when the monitor provides that control.
- Choose the monitor under Settings > System > Display > Advanced display and select the supported refresh rate.
- Enable G-SYNC/G-SYNC Compatible in NVIDIA Control Panel or FreeSync in AMD Software.
- Set the game to the intended resolution and presentation mode.
- Use the monitor OSD or GPU software to verify the active refresh and VRR state while the game is running.
- Apply V-Sync or a frame cap when frame rates exceed the display’s maximum, and disable Windows 11 DRR if it limits a VRR game’s maximum rate.
Once the monitor, GPU, port, cable, Windows mode and game settings all agree, the selected high refresh rate should remain available after reboots. If it disappears, start with the physical connection and monitor input, then recheck the driver and Windows mode list.
