Screen tearing on a gaming laptop looks like a horizontal split or jagged line that flashes across the display when you pan the camera or move quickly. The top and bottom halves of the image fall out of sync for a fraction of a second, so textures and straight edges appear offset, wobbly, or duplicated. You will notice it most in fast shooters, racing games, and open-world titles when sprinting and looking side to side, but it can happen in any game locked above or below your panel’s refresh rate.
This is a visual sync issue, not hardware failure, so it is not urgent and will not damage your panel or GPU. You can keep playing while you troubleshoot, but tearing makes aiming harder and gets worse at unstable frame rates. Most cases are fixed in under ten minutes by correcting a sync setting in Windows or your graphics driver. As of 2026 almost every gaming laptop includes a high refresh panel with some form of adaptive sync, so the right combination of settings will eliminate the tear line completely without needing a repair.
Likely Causes
| Cause | How to confirm | Fix difficulty |
|---|---|---|
| V-Sync disabled while GPU output exceeds refresh rate | Tearing appears when frame rate counter is higher than display Hz; disappears when you cap fps or enable V-Sync in game | Easy |
| Adaptive sync (G-Sync / FreeSync) off or unsupported in current mode | NVIDIA Control Panel or AMD Software shows G-Sync/FreeSync as Not Supported or Disabled; laptop uses Hybrid/MSHybrid graphics | Easy |
| Windows running display at wrong refresh rate | Settings > System > Display > Advanced display shows 60 Hz on a 144 Hz / 165 Hz / 240 Hz panel | Easy |
| Outdated, corrupted, or OEM-locked GPU driver | Tearing started after Windows Update; Device Manager shows Microsoft Basic Display Adapter or driver date older than 3 months | Moderate |
| Frame rate uncapped and fluctuating widely | In-game overlay shows fps swinging 40-50 fps above and below refresh rate instead of a steady line | Easy |
| Borderless window or overlay forcing desktop composition | Tearing only in borderless/windowed mode or when Discord/Steam overlay is active; exclusive fullscreen looks clean | Easy |
Fix 1: Turn On V-Sync in the Right Place
What causes it
Tearing happens when the GPU sends a new frame in the middle of the monitor’s refresh cycle. If V-Sync is off and your fps is higher than your panel’s Hz, the display shows parts of two frames at once.
How to check
Enable the in-game fps counter or press Alt + R to open the GeForce Experience overlay or Alt + Z then Performance. If your laptop is 144 Hz and you see 150-200 fps with a visible tear line, V-Sync is not actively limiting the output. Also check the game’s graphics menu under Display or Video for a Vertical Sync toggle.
What to do
Start with the in-game setting: set Vertical Sync to On and restart the game. If the game has no V-Sync option, force it in the driver. For NVIDIA: right-click desktop > NVIDIA Control Panel > Manage 3D settings > Global Settings or Program Settings > find Vertical sync > set to On > click Apply. For AMD: right-click desktop > AMD Software: Adrenalin Edition > Gaming > Graphics > Wait for Vertical Refresh > set to Always On. Test in game for one minute of rapid camera movement.
How to undo it
Return to the same menu and set Vertical Sync / Wait for Vertical Refresh back to Use the 3D application setting or Off. In NVIDIA Control Panel click Restore next to the dropdown, then Apply.
Fix 2: Enable G-Sync or FreeSync on Your Laptop Panel
What causes it
Gaming laptops with a discrete NVIDIA or AMD GPU often include adaptive sync that matches the panel’s refresh rate to the GPU’s frame output. If it is disabled, or the laptop is running in Hybrid mode through the integrated GPU, tearing returns even with V-Sync off.
How to check
For NVIDIA: open NVIDIA Control Panel > Display > Set up G-SYNC. If you do not see that page, your laptop is in Hybrid/MSHybrid mode and the iGPU is handling the display. Also check Windows > Settings > System > Display > Graphics > Change default graphics settings and note if Optimus or Hybrid is on. For AMD: open AMD Software > Display > AMD FreeSync > check if it reads Enabled or Not Supported.
What to do
Enable the hardware mux if available. Open your OEM control app such as Lenovo Vantage, ASUS Armoury Crate, HP Omen Gaming Hub, or Acer PredatorSense > find GPU Mode, Display Mode, or MUX Switch > select Discrete GPU or dGPU Only > restart when prompted. Then return to NVIDIA Control Panel > Set up G-SYNC > check Enable G-SYNC for windowed and full screen mode > check Enable settings for the selected display model > Apply. Under Manage 3D settings > Vertical sync set to On to pair with G-Sync correctly. On AMD, set AMD FreeSync to Enabled and Radeon Anti-Lag to Enabled.
How to undo it
Set the OEM app back to Hybrid or MSHybrid mode and restart. In NVIDIA Control Panel uncheck Enable G-SYNC and set Vertical sync back to Use the 3D application setting.
Fix 3: Set Windows to Your Panel’s Native Refresh Rate
What causes it
Windows sometimes defaults to 60 Hz after a driver update, dock, or HDMI connection, even on a 165 Hz or 240 Hz panel. Running a high-fps game at 60 Hz guarantees tearing or stutter.
How to check
Go to Settings > System > Display > Advanced display. Look at Refresh rate and Desktop mode. If you own a 144 Hz panel and it shows 60 Hz or 60.00 Hz, Windows is limiting the display. Press Win + P and confirm you are on PC screen only or Extend, not Duplicate, which can lock to the lowest Hz.
What to do
In Advanced display, click Choose a refresh rate and select the highest value listed, for example 144 Hz, 165 Hz, or 240 Hz. If the high value is missing, click Display adapter properties for Display 1 > Monitor tab > Screen refresh rate > select the correct Hz > Apply. For external monitors, use the cable that came with the display and connect directly to the HDMI 2.1 or USB-C DisplayPort port wired to the dGPU, not the iGPU-only port.
How to undo it
Reopen Advanced display and select 60 Hz again, or click Display adapter properties > Monitor tab > restore the previous rate. No restart is required.
Fix 4: Do a Clean Reinstall of the GPU Driver
What causes it
A partial driver install, Windows Update overwriting the OEM driver, or leftover profiles can break sync controls so toggles in NVIDIA Control Panel or AMD Software do nothing.
How to check
Open Device Manager > Display adapters > right-click NVIDIA GeForce RTX or AMD Radeon > Properties > Driver tab. If Driver Provider is Microsoft, or Driver Date is more than a few months old, the driver is generic or outdated. Also check C:\ProgramData\NVIDIA Corporation\Drs for corrupted profiles if V-Sync changes do not stick after Apply.
What to do
Download Display Driver Uninstaller (DDU) and the latest driver from NVIDIA.com Drivers or AMD.com Drivers and Support for your exact model. Disconnect from internet to block auto-install. Boot to Safe Mode by holding Shift while clicking Restart > Troubleshoot > Advanced options > Startup Settings > Restart > press 4. Run DDU > Select device type GPU > select NVIDIA or AMD > click Clean and restart. After reboot, install the downloaded driver, choose Custom (Advanced) > check Perform a clean installation > complete setup > restart. Reapply Fix 1 and Fix 2 settings.
How to undo it
Open Device Manager > Display adapters > right-click GPU > Properties > Driver tab > Roll Back Driver if available. Or rerun the driver installer and select the previous version you downloaded. Your driver files remain in C:\NVIDIA\DisplayDriver or C:\AMD\ if you need to reinstall an older package.
Fix 5: Cap Your Frame Rate Just Below Refresh Rate
What causes it
Even with V-Sync and adaptive sync on, an uncapped frame rate that constantly overshoots Hz can cause input lag or brief tearing at the ceiling. Capping fps stabilizes frame delivery.
How to check
With the in-game limiter set to Unlimited and V-Sync off, note the peak fps. If your panel is 165 Hz and fps regularly hits 170-250 fps, you need a cap. Under Manage 3D settings > Max Frame Rate or AMD Software > Frame Rate Target Control you will see Off or Disabled.
What to do
Set a cap 3 fps below your refresh rate for best adaptive sync behavior. In NVIDIA Control Panel > Manage 3D settings > Max Frame Rate > On > set value to 141 for 144 Hz, 162 for 165 Hz, or 237 for 240 Hz > Apply. In AMD Software > Gaming > Graphics > Frame Rate Target Control > Enabled > set the same 3-below value. Alternatively set the cap inside the game: look for Max FPS, Frame Rate Limit, or Custom Framerate Limit and enter the value. If the game has an NVIDIA Reflex + Boost option, set it to On + Boost and leave the driver cap in place.
How to undo it
Set Max Frame Rate back to Off in NVIDIA Control Panel or disable Frame Rate Target Control in AMD Software. In-game, set Max FPS back to Unlimited or Off.
Fix 6: Use the Correct Fullscreen Mode and Disable Conflicting Overlays
What causes it
Borderless windowed mode forces the game through Windows Desktop Window Manager, which can ignore driver V-Sync. Overlays from Discord, Steam, and GeForce Experience inject additional composition that breaks sync on some titles.
How to check
In game go to Settings > Display > Display Mode. If it shows Borderless Window or Windowed, you are not in exclusive fullscreen. Test by pressing Alt + Enter to toggle modes and see if tearing changes. Check if tearing stops after closing overlays: Discord > Settings > Game Overlay, Steam > Settings > In-Game, and GeForce Experience > Settings > In-Game Overlay.
What to do
Set Display Mode to Fullscreen or Exclusive Fullscreen and set Resolution to the native panel resolution such as 1920×1080 or 2560×1600. Apply and restart the game. Then disable overlays one by one: Discord > Settings > Game Overlay > Enable in-game overlay Off; Steam > Library > right-click game > Properties > General > uncheck Enable Steam Overlay while in-game; GeForce Experience > Settings > General > In-Game Overlay Off. Also disable Windows Game Bar: Settings > Gaming > Xbox Game Bar > Off.
How to undo it
Set Display Mode back to Borderless Window if you prefer fast Alt + Tab. Re-enable each overlay by toggling the same switches back to On.
Fix 7: Set Power, Thermal, and Battery Performance to Maximum
What causes it
Gaming laptops in Balanced or Eco mode, or running on battery, throttle the GPU and cause unstable frame times. The clock jumps create uneven pacing that looks like tearing even when sync is on.
How to check
Check Windows taskbar battery icon > note if set to Best battery life or Balanced. Open your OEM app > Performance Mode > see if Quiet, Balanced, or Eco is active. Press Fn + power mode key if present. While gaming on battery, unplug the 230W or similar AC adapter and observe if tearing worsens compared to AC power.
What to do
Plug in the original AC adapter. In Windows Settings > System > Power > Power mode select Best performance. In OEM app select Performance or Turbo. In NVIDIA Control Panel > Manage 3D settings > Power management mode > Prefer maximum performance > Apply. In Windows Settings > System > Display > Graphics > Change default graphics settings > turn off Power Saving GPU preferences for the game. Keep laptop on a hard flat surface so fans under the chassis can exhaust, and set Fan Curve to Performance if available.
How to undo it
Set Power mode back to Balanced or Best battery life and OEM app back to Balanced. In NVIDIA Control Panel set Power management mode back to Optimal power or Normal.
If Nothing Works
If the tear line persists across multiple games after the fixes above, isolate the display. Connect to an external monitor or TV via HDMI or USB-C DisplayPort and test the same game with identical sync settings. If tearing disappears externally, the laptop panel cable or panel timing may be faulty and needs warranty service. If tearing follows to the external display, the issue is system-wide.
Reset configuration to rule out a bad profile: close games > open NVIDIA Control Panel > Manage 3D settings > Restore Defaults > Apply, or AMD Software > Settings > System > Reset. Then delete the game’s config file found in Documents\My Games\[Game Name] or %USERPROFILE%\AppData\Local\[Game Name]\Saved\Config and let the game rebuild it. Verify game files through Steam > Library > right-click game > Properties > Installed Files > Verify integrity of game files. Finally, test with Hybrid/MSHybrid toggled the opposite way and with all external adapters and docks removed, since docks often limit refresh rate and disable G-Sync.
FAQ
Should I use V-Sync, G-Sync, or both on a gaming laptop?
Use both together. Enable G-Sync or FreeSync for the panel, enable V-Sync in the driver, and cap fps 3 below Hz as in Fix 5. G-Sync handles variable frame rates without tearing and driver V-Sync prevents the tear at the very top of the range. Do not disable V-Sync when G-Sync is on if you want zero tearing.
Why does screen tearing get worse on battery power?
On battery the system lowers GPU clocks and may force the display through the iGPU to save power. That creates uneven frame delivery and can disable adaptive sync. Always play plugged in with Power mode set to Best performance and GPU Mode set to Discrete or dGPU Only if you want consistent sync.
Can an HDMI cable cause screen tearing?
The cable does not create tearing directly, but an older HDMI cable or the wrong port can limit you to 60 Hz or prevent G-Sync. Use the HDMI or USB-C port marked as dGPU or DisplayPort 1.4 and a certified Ultra High Speed cable if you play on an external display above 120 Hz. Then re-check Settings > System > Display > Advanced display to confirm the full refresh rate is available.
Does capping frame rate increase input lag?
Capping alone adds very little lag compared to uncapped V-Sync at the Hz ceiling. A cap 3 below Hz plus G-Sync keeps latency lower than V-Sync On with no cap. If you need the lowest lag for competitive play, enable NVIDIA Reflex or AMD Anti-Lag+ in the game and keep the driver fps cap in place.
