If horizontal “cuts” appear only while you pan the camera or move quickly, the most likely cause is ordinary screen tearing: the GPU presents a new frame while the monitor is still refreshing the previous one. Intel describes the result as a horizontal image split, and NVIDIA gives the common example of a GPU delivering 120 frames per second to a 60 Hz display (Intel; NVIDIA).
Set Windows to the monitor’s intended refresh rate, enable FreeSync, Adaptive-Sync or G-SYNC-compatible mode, cap frame rate just below the display’s maximum, and use V-Sync if necessary. Lines that remain visible when the game is paused, on the desktop, in BIOS or in the monitor’s own menu need cable, signal and hardware testing instead.
First, identify which problem you have
Typical screen tearing
- It appears during camera pans, scrolling or rapid movement.
- It looks like a horizontal break where two frames do not line up; the boundary can move up or down.
- It disappears in a paused game or static scene.
- It is absent from the Windows desktop, BIOS and the monitor’s on-screen display.
Signs of display or signal corruption
- Lines remain while paused or appear on the desktop, boot screen or monitor menu.
- The image flickers, flashes, shows colored blocks, turns partly black or loses signal.
- The symptom occurs in several applications or on another computer.
- Moving the cable or touching a connector changes the result.
Those signs make a marginal cable, incompatible bandwidth or timing, overheating, a failing GPU, damaged panel or power problem more likely than V-Sync trouble.
Does it happen in one game or everywhere?
| Where it occurs | What to investigate first |
|---|---|
| One game | That game’s V-Sync, frame limiter, fullscreen mode, resolution, HDR and graphics API. |
| Every 3D game | Windows refresh rate, VRR, driver settings, cable bandwidth and monitor configuration. |
| Desktop as well as games | Driver, display mode, cable, monitor and other hardware. |
| Only borderless or windowed mode | Compare exclusive fullscreen and check compositor, HDR and windowed-game behavior; borderless is not automatically tear-free. |
Set the correct Windows refresh rate
- Open Settings.
- Go to System > Display and select the affected monitor if more than one is connected.
- Open Advanced display.
- Under Choose a refresh rate, select the monitor’s supported target (144, 165 or 240 Hz, for example).
- If that mode is unstable, test the next lower standard rate such as 120 Hz or 60 Hz.
Microsoft notes that the choices depend on the display and hardware, and that higher refresh rates can reduce tearing (Microsoft’s refresh-rate guide). Windows 11 Dynamic Refresh Rate requires a compatible variable-refresh display and at least 120 Hz; disable DRR for a game if it unexpectedly drops to a low refresh rate.

Choose a synchronization method
V-Sync
V-Sync makes frame presentation wait for the monitor’s refresh cycle. Turn it on in the game first. It can remove ordinary tearing, but traditional V-Sync may add input latency or stutter when frame rate falls below the display target (Intel; NVIDIA).
Variable refresh rate
FreeSync, Adaptive-Sync and G-SYNC-compatible modes let a supported monitor change refresh timing with GPU frame rate. They usually offer a better smoothness/latency balance, but only inside the monitor’s VRR range and with compatible GPU, port, cable and driver settings (AMD FreeSync; NVIDIA VRR).

FPS limiting
Use the game’s limiter first, then a driver limiter if needed. Start a few frames below the maximum refresh rate—about 141 FPS on 144 Hz or 162 FPS on 165 Hz—and adjust for frame-time stability. This is a starting point, not a universal rule, and an FPS cap alone does not guarantee tear-free output on a fixed-refresh display.
Configure VRR and V-Sync in order
- Enable FreeSync, Adaptive-Sync or G-SYNC-compatible mode in the monitor’s own menu.
- Connect directly to the discrete GPU where applicable, not through a dock, splitter or KVM for the baseline test.
- Enable VRR in the GPU control panel and select the correct monitor and refresh rate.
- Set an in-game FPS cap below the maximum refresh rate.
- Test with in-game V-Sync off, then on if tearing remains.
- If VRR flickers or loses signal, try a lower refresh rate, disable HDR temporarily, change cable or port, and retest.
NVIDIA checks
- Open NVIDIA Control Panel > Display > Set up G-SYNC and confirm the display appears.
- Choose fullscreen or fullscreen plus windowed mode as appropriate.
- Under Manage 3D settings, check Vertical sync and Preferred refresh rate; use Program Settings for a game-specific profile.
- Use a cap slightly below the monitor’s stable maximum and compare driver V-Sync with in-game V-Sync.
- If the issue began after a driver update, perform a clean install or test the previous known-good driver.
Menu names and available options vary by driver, monitor certification and connection type. NVIDIA’s references are G-SYNC setup and 3D settings.

AMD checks
- In AMD Software, confirm FreeSync is enabled for the affected display.
- Verify Windows is using the monitor’s maximum stable refresh rate.
- Check whether Radeon Chill, Enhanced Sync, a driver-level V-Sync or another limiter overrides the game.
- Disable HDR temporarily if the symptom is flicker or corruption rather than a clean moving tear.
- Try a lower refresh rate if the current mode is unstable.
FreeSync implementations differ in VRR range, overdrive, HDMI/DisplayPort support and GPU compatibility (AMD documentation).
Intel and laptop checks
- Confirm the Windows refresh rate.
- Enable V-Sync in the game or Intel graphics software.
- Update or roll back the driver if the symptom follows a driver change.
- Test another cable and connection type.
- On a laptop, check whether the panel output is physically connected to integrated graphics even when rendering uses the discrete GPU.
- Test with HDR and VRR disabled.
Intel documents both ordinary tearing and DisplayPort/VRR corruption cases, so persistent artifacts should not automatically be labeled tearing (tearing guidance; DisplayPort/VRR example).

Run a controlled hardware and signal test
Capture and compare the symptom
Record the game name, GPU and monitor models, HDMI/DisplayPort/USB-C path, refresh rate, VRR state and display mode. A line visible in a screen recording may originate in rendering or software; a line visible only to your eyes or a camera may be occurring after rendering in the cable, panel or scanout path. This is a useful clue, not a definitive hardware test.
Change one connection variable
- Try a different DisplayPort or HDMI cable and another GPU port.
- Use a direct GPU-to-monitor connection instead of a dock, splitter, KVM or adapter.
- Lower resolution or refresh rate and disable HDR temporarily.
- Turn off monitor refresh overclocking, GPU overclock/undervolt, custom resolutions, sharpening, overlays and capture tools.
A cable that works at 60 Hz can fail at higher resolution, refresh, color depth or HDR. Do not assume a particular HDMI or DisplayPort version without checking both devices’ specifications.

Multi-monitor, VRR and presentation edge cases
Mixed refresh rates, resolutions, HDR settings and connection paths can complicate desktop composition. Disconnect the secondary display or press Windows + P > PC screen only and retest. Microsoft has documented duplicated-monitor cases with a horizontal tear boundary (Microsoft support).
VRR flicker usually looks like brightness pulsing or intermittent instability as frame rate crosses the VRR range; temporarily disabling VRR helps isolate it but does not prove the feature is defective. Windowed and borderless presentation also depends on the game, compositor and graphics API (Microsoft DirectX documentation).
When replacement or warranty service is justified
Do not buy a GPU or monitor before isolation testing. A replacement cable is sensible when changing cable or port removes high-refresh, HDR or VRR failures. A VRR monitor is an upgrade for a fixed-refresh display that regularly tears, not a cure for lines visible in BIOS or the monitor menu. A faster GPU raises achievable frame rate but does not itself synchronize frames. If artifacts follow one monitor or GPU through cross-tests, use the manufacturer’s warranty/RMA route (NVIDIA, AMD, Intel).
Quick Recap
Final decision path
- Only during movement? Set refresh rate, then test VRR, an FPS cap and V-Sync.
- Visible on desktop, BIOS or monitor menu? Treat it as signal or hardware corruption.
- Fixed by another cable or port? Replace or avoid the failing link.
- Follows the monitor? Suspect its panel or electronics.
- Follows the GPU/computer? Investigate driver, GPU, power and slot.
- Fixed by synchronization? Keep the configuration that removes tearing without unacceptable latency or stutter.
