That coordination is designed to reduce visible tearing and uneven stutter. To enable it, turn on the monitor’s Adaptive-Sync, FreeSync or VRR option first, then enable and verify the matching feature in NVIDIA Control Panel or AMD Software: Adrenalin Edition.
What adaptive sync changes on screen
A conventional monitor refreshes on a fixed schedule—60, 120, 144 Hz or another chosen rate—whether the game has a new frame ready or not. A graphics processor, however, rarely renders at a perfectly constant rate. A busy scene may take longer than a simple one, so frame delivery can vary from moment to moment.

With VRR enabled, the display can vary its refresh timing within its supported range. Instead of refreshing on its own rigid cadence, it waits for compatible frame output and presents the next frame at a better-matched time. NVIDIA describes G-SYNC as matching the monitor’s refresh rate to the GPU frame rate; AMD describes FreeSync as synchronizing display refresh with compatible graphics frame rate. Those are intended-behavior claims from the vendors, not a promise that every game, cable, input or frame rate will look identical.
Why fixed refresh can tear
If the GPU replaces the image while the panel is partway through a refresh, the upper and lower portions of the screen can show different frames. The horizontal break is commonly called tearing. If the display repeatedly refreshes before a new frame is ready, the same frame may remain on screen for multiple refreshes, producing uneven motion or stutter.

What adaptive sync does not do
- It does not create extra frames or increase the game’s rendering performance.
- It does not make an incompatible monitor variable-refresh capable through software alone.
- It does not guarantee that every refresh rate, window mode, game engine or connection will support VRR.
- It does not remove the need for a suitable graphics driver and a supported GPU output.
The practical result depends on the entire path: monitor electronics and firmware, the selected input, cable and GPU output, driver, operating system, game and the frame-rate range at which the game runs.
Adaptive Sync, FreeSync, G-SYNC and VESA AdaptiveSync are not identical labels
“Adaptive sync” is often used as a general description of variable-refresh capability. FreeSync and G-SYNC are vendor technologies and certification or validation programs built around that capability. DisplayPort Adaptive-Sync is an industry-standard link feature; AMD describes it as an ingredient of a DisplayPort link that enables the real-time refresh adjustment used by technologies such as FreeSync.
| Label or term | What it indicates | Important qualification |
|---|---|---|
| Adaptive sync / VRR | A display can vary refresh timing when the monitor, GPU, connection and software support it. | The label alone does not establish which input, operating mode or refresh range works. |
| AMD FreeSync | AMD’s variable-refresh technology for compatible graphics and certified displays. | AMD certification and supported connections are model-specific; HDMI and DisplayPort support can differ by display. |
| NVIDIA G-SYNC display | A display using NVIDIA’s G-SYNC implementation. | GPU-generation and system requirements differ from those for G-SYNC Compatible displays. |
| NVIDIA G-SYNC Compatible | A VRR display validated by NVIDIA for the listed experience. | NVIDIA also lets users try G-SYNC on some unvalidated VRR displays, but that attempt is not certification and has no guaranteed result. |
| VESA AdaptiveSync | A standards-based certification category for variable refresh. | AMD says VESA AdaptiveSync certification does not necessarily mean the monitor also has AMD FreeSync certification. |
When a monitor advertises more than one label, verify the exact model, input and supported range in its manual. A general “VRR” specification is not proof that every port supports the feature at the monitor’s maximum refresh rate.
Prepare the monitor and PC before changing software settings
- Read the monitor manual and open its on-screen display (OSD). Look for Adaptive-Sync, FreeSync, VRR or a similar control. Enable it. The name and menu location vary by model.
- Use a GPU output and monitor input that support the intended VRR mode. AMD documents FreeSync over DisplayPort and HDMI on certified displays. An older AMD setup FAQ specifies DisplayPort 1.2 or newer for the DisplayPort configuration it describes; that is not a universal cable rule for every monitor. Check both manuals rather than assuming that all inputs on one display behave the same way.
- Install a suitable graphics driver. Driver menus and supported combinations change, so the current documentation for your GPU and monitor takes precedence over a generic walkthrough.
- Set the operating system and monitor to the refresh rate you intend to use. A high-refresh monitor running at a lower desktop rate can make troubleshooting confusing, and a monitor’s VRR range may depend on the selected mode.
- For a multi-monitor setup, identify the gaming display. GPU software may show several screens with similar names. Select the active monitor rather than changing a different display.
On compatible AMD systems with a certified display, AMD says Adrenalin can enable FreeSync automatically. You should still check the monitor OSD and the software status, because automatic behavior does not prove that the selected port or mode is the one you intended.
How to enable G-SYNC or G-SYNC Compatible on NVIDIA
The labels below reflect NVIDIA’s documented Control Panel path; NVIDIA’s setup page carries a 2023 copyright footer, so wording can change in later driver releases.
- Connect the monitor to the supported output on the NVIDIA GPU, turn the monitor on and make it the primary display in the operating system if it is not already.
- Open NVIDIA Control Panel.
- Choose Display > Set up G-SYNC.
- Check Enable G-SYNC/G-SYNC Compatible.
- Choose whether it should apply to Full screen mode or Windowed and full screen mode. Use the mode that matches how you play; windowed support can depend on the game and driver.
- If more than one display is listed, select the gaming monitor and apply the display-specific setting when offered.
- Open Manage 3D Settings and check Monitor Technology. Set it to G-SYNC or G-SYNC Compatible for the relevant profile when that option is available.
NVIDIA lists separate supported GPU generations and system requirements for G-SYNC displays and G-SYNC Compatible displays. Windows version, driver, application and display requirements can vary, so use the current supported-hardware information for your specific combination. If the monitor is not validated, NVIDIA’s option to apply G-SYNC settings can be useful for a trial, but a successful checkbox state does not turn that display into a validated G-SYNC Compatible model.

Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- Turn on FreeSync or Adaptive-Sync in the monitor OSD.
- Open AMD Software: Adrenalin Edition.
- Open Display settings and select the active gaming display. In a multi-monitor setup, confirm that you selected the monitor you are configuring.
- Under Global Display, check the AMD FreeSync status and the tier reported for that display.
- Leave the feature enabled if the status confirms compatibility. The same screen lets you disable it when diagnosing a problem.
- Use a game-specific profile only when you need different behavior for one title; otherwise, keep the global setting consistent while testing.
If FreeSync does not appear, return to the monitor OSD and connection checks before reinstalling software. AMD notes that some monitor presets or custom image modes can disable FreeSync, and its menu labels can differ by display.
How to verify that VRR is actually active
- Confirm the monitor’s OSD option remains enabled after you apply the setting. Some picture presets can change it.
- In NVIDIA Control Panel, revisit Set up G-SYNC and confirm the correct display and mode are selected. Check Monitor Technology in Manage 3D Settings as well.
- In AMD Software, check the selected display’s FreeSync status and tier under Global Display.
- Test with a game that changes its rendering load. Look for the specific problem you were trying to solve—tearing during camera movement or uneven motion—not merely whether the game launches.
- Repeat the test in the window mode you normally use. Full-screen and windowed-and-full-screen behavior can differ, especially on NVIDIA systems.
A status indicator confirms that software sees a compatible path; it does not certify every game or every frame-rate condition. If the visual result changes when you switch the feature off and on in the same scene, that is useful evidence that the path is active, but it is not an independent performance test.
When the adaptive-sync setting is missing
The monitor has no VRR control
Check the model’s specifications and manual. A monitor must support VRR, FreeSync or G-SYNC hardware features; a driver cannot add the capability to a fixed-refresh panel. If the specification mentions VRR but the OSD has no control, check whether the option appears only with a particular input or picture mode.
The wrong display is selected
In a multi-monitor setup, choose the gaming display in NVIDIA Control Panel or AMD Software before looking for the setting. AMD specifically calls out selecting the active display when checking FreeSync status.

Choose the input that matches the target resolution, refresh rate, and source-device capability. This helps keep a dedicated work computer and a separate personal or media source ready on the same desktop.
A monitor preset disabled it
Return to the manufacturer-recommended display mode and inspect the OSD again. AMD says some presets and custom settings can disable FreeSync. Change one setting at a time so you know which change restored the control.
NVIDIA shows no G-SYNC page or option
Verify that the monitor is connected, enabled and configured as the primary display. In Manage 3D Settings, check whether Monitor Technology offers G-SYNC or G-SYNC Compatible. Confirm that the GPU generation and display are within NVIDIA’s current supported requirements. An unvalidated display may be available only through the option to try G-SYNC settings, and that option does not guarantee stable behavior.
AMD reports no FreeSync status
Confirm the OSD setting, select the correct display under Display, and inspect Global Display. Check the driver version and the monitor’s supported input. AMD’s current instructions use the Adrenalin 23.9.1 interface as their example, so a later release may place the same information under a different label.
VRR is enabled but tearing remains
Check whether the game is rendering above the monitor’s maximum refresh rate. AMD suggests enabling V-Sync or capping the frame rate for a tear-free experience in that situation. Treat either choice as optional tuning, not a prerequisite for turning on VRR. Test the game’s full-screen and windowed modes separately, and check whether its frame rate is staying outside the monitor’s supported range.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Refresh range, low-framerate compensation and FreeSync tiers
Every VRR monitor has a usable minimum and maximum refresh rate. When the game’s output falls below that range, the display cannot simply follow every frame one-for-one. Low-framerate compensation (LFC) addresses that gap on supported displays by repeating frames so the panel remains inside its operating range.
AMD FreeSync Premium
AMD defines the FreeSync Premium tier as requiring at least 120 Hz at minimum Full HD resolution and LFC. The “at least” qualification applies to AMD’s tier specification; it does not mean every Premium monitor has the same resolution, maximum refresh rate or input support.

How AMD’s LFC example works
AMD explains that on a 60–144 Hz display, a game running at 40 frames per second can have each frame displayed twice so the panel refreshes at 80 Hz. This 40-to-80 example is AMD’s explanation of LFC, not a universal result for every display or game. The monitor must support LFC and the frame rate must fall within the conditions defined for that model.
Choosing a monitor or connection for adaptive sync
If your current display lacks VRR, choose a monitor only after matching the complete system rather than buying on a label alone. Use these checks:
| Check | Question to answer |
|---|---|
| GPU and operating system | Does your graphics processor, driver and operating system support the monitor’s FreeSync, G-SYNC or other VRR mode? |
| Validation status | Is the display an NVIDIA-validated G-SYNC Compatible model, an AMD-certified FreeSync model, a G-SYNC display, a VESA AdaptiveSync display, or only described generically as VRR? |
| Port and cable | Which exact monitor input and GPU output support VRR, and at what resolution and refresh rate? |
| Refresh range | What are the stated minimum and maximum refresh rates? Is LFC specified? |
| Tier features | If HDR matters, does the claimed tier include the required HDR, color and luminance certification? |
| Game and display mode | Will your games run in the supported full-screen or windowed mode? |
A DisplayPort or HDMI cable is a conditional purchase, not an automatic requirement. Replace it only when the current cable or port fails the particular monitor-and-GPU requirements documented for your desired resolution and refresh rate.
A practical setup sequence
For most systems, this order avoids the commonest dead ends:
- Confirm the monitor model’s VRR feature, supported range and supported inputs.
- Connect the monitor directly to the gaming GPU using the documented port.
- Set the intended desktop refresh rate.
- Enable Adaptive-Sync, FreeSync or VRR in the monitor OSD.
- Install or update the graphics driver.
- Enable G-SYNC in NVIDIA Control Panel or check FreeSync in AMD Software.
- Test the game in the window mode you use most often.
- If tearing occurs above the monitor’s maximum refresh rate, try the game’s V-Sync or a frame-rate cap as an optional tuning step.
- If the control disappears, undo the last display preset, input or driver change and repeat the OSD and connection checks.
That sequence matters because GPU software cannot compensate for a disabled monitor-side feature, an unsupported input or a display selected incorrectly in a multi-monitor setup.
