For most Windows gamers with a supported variable-refresh-rate display, the reliable path is to enable G-SYNC in NVIDIA Control Panel, select the correct display and mode, confirm the monitor is using G-SYNC technology, then choose V-SYNC, Reflex and frame-rate limits according to whether you value tear-free motion or the lowest possible latency. The best settings are not identical for every game or monitor.
What G-SYNC does and what you need
G-SYNC synchronizes a monitor’s refresh timing with the frames produced by an NVIDIA GPU. Instead of refreshing at a fixed interval while the GPU is partway through a new frame, a variable-refresh display waits for the next completed frame within its supported range. That is why G-SYNC can reduce visible tearing and uneven frame pacing. NVIDIA describes the technology as matching the monitor’s refresh rate to the GPU frame rate and says it eliminates tearing while minimizing stutter and input lag in 3D applications and games.
G-SYNC is not a software-only switch. You need a display that supports G-SYNC or that NVIDIA has validated as G-SYNC Compatible, an NVIDIA GPU and driver that support the display, and a connection and display mode that expose variable refresh. A monitor can advertise adaptive sync yet fail to behave correctly with a particular GPU, driver, game or connection.

NVIDIA’s reference documentation lists Windows 7 or later for G-SYNC displays and Windows 10 or later for G-SYNC Compatible displays. The same documentation distinguishes older hardware requirements: G-SYNC displays are listed with GeForce GTX 650 Ti BOOST or later, or Kepler-class or later Quadro hardware; G-SYNC Compatible displays are listed with Pascal-class GPUs or later. Those pages are older than the current NVIDIA App and current GPU generations, so treat the list as historical documentation rather than a guarantee for a specific modern model. Check the exact monitor, GPU and driver support before making a purchase or troubleshooting a missing option.

G-SYNC versus G-SYNC Compatible
| Display type | What it means | How to approach setup |
|---|---|---|
| G-SYNC display | Uses NVIDIA’s G-SYNC display implementation. | Enable it in NVIDIA Control Panel and verify the display-specific option. |
| G-SYNC Compatible display | A variable-refresh display validated by NVIDIA for use with G-SYNC. | Enable G-SYNC/G-SYNC Compatible and test the games you play. |
| Unvalidated adaptive-sync display | Variable refresh may work, but NVIDIA has not validated that model as G-SYNC Compatible. | NVIDIA documents an option to enable display-specific settings for testing; do not treat that as a compatibility guarantee. |
Before changing settings
- Install a current NVIDIA driver that supports your GPU and display.
- Connect the monitor directly to the GPU rather than to a motherboard video output or an adapter that removes variable-refresh support.
- Turn on the monitor’s adaptive-sync, FreeSync or G-SYNC option if its on-screen menu provides one.
- Use Windows display settings or the current NVIDIA display page to select the monitor’s intended supported refresh rate. NVIDIA’s older G-SYNC documentation specifically advises selecting the highest available refresh rate, but menu names and available modes vary by hardware.
- If you use more than one monitor, identify which display will run games and make it the Windows primary display during setup.
How do I set up G-SYNC in NVIDIA Control Panel?
Control Panel remains the clearest documented fallback because the NVIDIA App’s labels and locations change with app and driver releases. Use this sequence on the PC that will run your games.
- Right-click the Windows desktop and open NVIDIA Control Panel.
- In the left navigation, open Display > Set up G-SYNC.
- Check Enable G-SYNC/G-SYNC Compatible.
- Choose the operating mode that matches your games. Select Full screen mode if you play only exclusive full-screen games or if windowed applications have trouble. Select Windowed and full screen mode if you want G-SYNC to cover borderless or ordinary windowed games as well.
- In the display list, select the monitor on which you will play. Confirm that it is connected, enabled in Windows and set as the primary display when appropriate.
- Apply the change.
- Open Manage 3D Settings. In the global or game-specific profile, check Monitor Technology and choose G-SYNC or G-SYNC Compatible when that choice is available.
- Launch a game and test movement, camera pans and menus. If the game behaves differently in exclusive full screen and borderless mode, test the mode you actually intend to use.
For an unvalidated variable-refresh monitor, NVIDIA documents a display-specific setting that lets you test G-SYNC. Enable it only for the selected display and evaluate the result in your own games. Flicker, blanking, loss of variable refresh or an unstable range means the monitor, connection, driver or game combination needs further investigation; the toggle does not certify the display.
Should G-SYNC be on for windowed games?
Choose Windowed and full screen mode when you regularly play borderless or windowed games, stream in a window, or switch between a game and other applications. Choose Full screen mode when you want the narrowest compatibility target or when a particular windowed application causes flicker, fails to engage variable refresh or behaves erratically.

How the NVIDIA App fits into setup
The current NVIDIA App is described by NVIDIA as a place to customize graphics settings, update supported DLSS features, tune GPU and game settings, and use Smooth Motion on supported GeForce RTX 50- and 40-series GPUs. NVIDIA feature announcements have placed G-SYNC controls under System > Displays and per-game or global driver controls under Graphics, but exact labels depend on the installed app and driver.
Open the app and look for display controls under System > Displays, then graphics profiles under Graphics. If your version presents different names, follow the labels shown in that installation. If G-SYNC is absent, do not assume the monitor is unsupported: use NVIDIA Control Panel > Display > Set up G-SYNC and Manage 3D Settings instead.
Do not confuse Smooth Motion with G-SYNC
Smooth Motion is a driver-based frame-interpolation feature for compatible games and hardware. NVIDIA identifies support for selected GeForce RTX 50- and 40-series GPUs. It generates additional frames according to its own compatibility requirements; it does not replace the variable-refresh synchronization performed by G-SYNC. Treat Smooth Motion as a separate, optional feature and evaluate image quality, latency and game compatibility independently.
Do not treat Optimal Settings as a G-SYNC wizard
NVIDIA App’s “Optimal Settings” feature is intended to balance game graphics quality and performance. It is not a G-SYNC setup wizard and does not establish the right V-SYNC, Reflex or frame-cap policy for every display. Apply it only if you want its graphics-quality recommendations, then configure synchronization and latency settings separately.

Should V-SYNC be on with G-SYNC?
V-SYNC and G-SYNC solve different parts of the timing problem. G-SYNC varies the display refresh to follow GPU output; V-SYNC controls what happens when the GPU output reaches or exceeds the display’s refresh behavior. NVIDIA’s latency guide describes one tear-avoidance configuration: keep V-SYNC on while using NVIDIA Reflex or NVIDIA Ultra Low Latency Mode. In the guide’s GPU-bound scenario below the display’s refresh rate, the driver automatically caps frame rate below refresh. NVIDIA also notes that this arrangement has slightly higher latency than allowing uncapped frame rates with Reflex.
| Priority | Configuration to consider | What to expect |
|---|---|---|
| Absolute tear avoidance | G-SYNC enabled, V-SYNC on, and Reflex or Ultra Low Latency Mode where supported. | Designed to avoid tearing in NVIDIA’s described scenario, with a small latency cost compared with uncapped Reflex. |
| Minimum possible latency | G-SYNC enabled with an uncapped frame rate and Reflex where the game supports it. | Can reduce latency, but frames that exceed the display’s behavior can produce tearing. |
| Game-specific behavior | Use the game’s own V-SYNC and latency controls when the presentation mode or laptop design requires them. | Behavior varies by engine, mode and hardware; verify with the game rather than assuming a global setting applies. |
The Control Panel V-SYNC ON behavior described by NVIDIA applies only to full-screen applications. For windowed mode, or for laptops using Microsoft hybrid graphics, NVIDIA points to the game’s in-game V-SYNC for the combined approach. These are documented exceptions, not reasons to force one setting on every system.
Reflex, Ultra Low Latency Mode and frame caps
NVIDIA Reflex
When a game supports NVIDIA Reflex, enable it in the game first and compare responsiveness with it disabled. Reflex manages the rendering pipeline for supported titles. Its interaction with V-SYNC is the trade-off described above: V-SYNC can preserve tear-free output, while uncapped Reflex can provide lower latency at the cost of possible tearing.

Pick the symptom - the matching free tool is one click away.
Ultra Low Latency Mode
For games without Reflex, NVIDIA’s latency guidance identifies Ultra Low Latency Mode as an alternative to consider with V-SYNC. It is a driver setting, so apply it globally only when you want the same behavior across games; otherwise use a per-game profile in Manage 3D Settings.

Max Frame Rate
NVIDIA’s Max Frame Rate setting is a ceiling for a 3D game or application. NVIDIA identifies uses such as reducing power consumption or system latency in certain scenarios, but its reference does not establish one cap that suits every refresh rate, game or GPU. Set a game-specific value based on your display’s refresh range, the frame rate your system can sustain and whether your priority is quiet operation, consistent pacing or minimum latency.
Use the game’s own limiter when it offers a reliable implementation and the NVIDIA driver limiter when you need a profile-level ceiling. Test one limiter at a time so you can identify which one controls the result. Do not present the popular “three frames below refresh” rule as an NVIDIA requirement; the official material does not support that universal prescription.
A practical decision framework
- You mainly play exclusive full-screen games: start with Full screen mode, G-SYNC enabled and the display’s highest supported refresh rate.
- You mainly play borderless or windowed games: start with Windowed and full screen mode and verify that each important game actually engages variable refresh.
- You want no visible tearing: consider V-SYNC on with G-SYNC and Reflex or Ultra Low Latency Mode, accepting the latency trade-off and the full-screen or hybrid-laptop exceptions.
- You compete for the lowest latency: test uncapped output with Reflex where available, then decide whether occasional tearing is acceptable.
- Your frame rate fluctuates widely: use a cap only after measuring the game’s sustained performance and checking its own limiter; a stable target is more useful than an arbitrary number.
- Your monitor is not G-SYNC Compatible certified: use the documented display-specific test option, but judge success by actual stability rather than the presence of a checkbox.
Why is the G-SYNC option missing?
The display is connected to the wrong output
Confirm that the cable is connected to the NVIDIA GPU and that Windows detects the intended monitor. On a desktop, a motherboard video output can bypass the discrete GPU. On a laptop, the internal panel may be routed through hybrid graphics, which changes which controls are available.
The monitor is disabled or not primary
Open Windows display settings, identify the gaming panel, enable it and make it the primary display when appropriate. Return to Set up G-SYNC and check the display list again.

The monitor’s variable-refresh mode is off
Open the monitor’s on-screen menu and enable its adaptive-sync or equivalent option. Then restart NVIDIA Control Panel. The exact menu name is manufacturer-specific, so do not assume that a Windows checkbox alone enables the panel.
The connection or mode does not expose variable refresh
Try the display mode and refresh rate that the monitor documents as supported. A cable or adapter is worth investigating only when the current link fails to expose the required display mode; there is no general requirement to buy a new cable for G-SYNC.
The driver or app is presenting different controls
NVIDIA App navigation changes over time. If the app lacks a G-SYNC control, use the documented Control Panel path. Install a driver appropriate for the GPU and monitor, then check both the app and Control Panel rather than assuming one interface reflects every available feature.

- Set the intended refresh rate in Windows or the current NVIDIA display page.
- Enable G-SYNC for the mode you use and confirm Monitor Technology in the game’s profile.
- Run a game with camera motion and high-contrast edges, where tearing is easy to see.
- Compare exclusive full screen with borderless mode if you enabled both.
- Observe whether the monitor flickers, blanks, loses signal or remains at a fixed refresh rate. Those symptoms indicate a compatibility or configuration problem rather than a reason to force the setting.
- Change only one variable at a time—display mode, V-SYNC, Reflex, frame cap or driver profile—so you can identify the setting that changes the behavior.
Common mistakes to avoid
- Enabling G-SYNC but leaving the game on a display that is not selected in the G-SYNC page.
- Assuming G-SYNC automatically covers windowed games when Full screen mode is selected.
- Calling Smooth Motion a G-SYNC switch; it is separate frame interpolation.
- Using NVIDIA App Optimal Settings as a substitute for synchronization setup.
- Applying a fixed frame-cap number to every monitor and game without checking sustained performance.
- Treating an unvalidated adaptive-sync monitor as guaranteed compatible.
- Assuming a 2020 latency guide or older reference page describes every behavior of a modern game, driver or laptop.
Recommended starting profiles
| Use case | Starting settings | Adjust when |
|---|---|---|
| Single-monitor, full-screen gaming | G-SYNC enabled; Full screen mode; highest supported refresh rate; Monitor Technology set to G-SYNC/G-SYNC Compatible. | Switch to combined windowed/full-screen mode if you begin using borderless games. |
| Mixed windowed and full-screen gaming | G-SYNC enabled; Windowed and full screen mode; verify each game’s presentation mode. | Use full-screen-only mode if a windowed application flickers or fails to synchronize. |
| Tear-free play with supported latency features | G-SYNC enabled; V-SYNC on; NVIDIA Reflex or Ultra Low Latency Mode where supported. | Turn V-SYNC off only if you accept tearing in exchange for lower latency. |
| Unvalidated VRR monitor | Enable the display-specific G-SYNC test option and use the monitor’s documented VRR mode. | Revert if you see flicker, blanking, signal loss or inconsistent behavior; verify the monitor, driver and connection. |
What to remember
G-SYNC is a display-and-GPU synchronization feature, not a universal performance preset. Start with the documented Control Panel setup, select the mode that matches your games, confirm the correct monitor and refresh rate, and treat V-SYNC, Reflex, Smooth Motion and frame caps as separate decisions. NVIDIA’s own guidance describes meaningful trade-offs rather than one setting that is optimal for every player.
