If you've ever noticed a horizontal line cutting across your screen mid-game, where the top half of the image doesn't quite line up with the bottom half, you've experienced screen tearing. It looks like someone has taken a slice out of your display and shifted it sideways, and once you've seen it, it's hard to unsee.
The good news is it's almost always fixable. Understanding why it happens is the first step to getting rid of it.
Why Screen Tearing Happens
Your monitor refreshes the image on screen at a fixed rate, measured in hertz. A 60Hz monitor updates 60 times per second. A 144Hz monitor updates 144 times per second. This is your refresh rate, and it's constant. The monitor ticks along like a metronome, redrawing the screen on its own schedule regardless of what your GPU is doing.
Your graphics card, on the other hand, renders frames as fast as it can. Sometimes that's slower than your monitor's refresh rate. Sometimes it's faster. And sometimes it's just slightly out of sync.
Tearing happens when your GPU delivers a new frame to the monitor partway through a refresh cycle. The monitor has already started drawing the previous frame from the top of the screen, but partway down it receives new image data and switches to the new frame. The result is a visible seam across the display where two different frames meet. That seam is the tear.
The Classic Fix: V-Sync
V-Sync, or vertical synchronisation, was the original solution to screen tearing. It works by capping your GPU's frame output to match your monitor's refresh rate and synchronising the two so that new frames are only sent at the start of a new refresh cycle. No misaligned frames, no tearing.
It sounds ideal, but V-Sync comes with its own problems. When your frame rate drops below your monitor's refresh rate, V-Sync can cause it to halve abruptly, so if you drop below 60fps on a 60Hz monitor, it locks down to 30fps rather than staying somewhere in between. This creates noticeable stuttering that many people find just as distracting as tearing.
V-Sync also adds input lag, a slight delay between what you do with your mouse or keyboard and what appears on screen. In fast-paced games, that lag is genuinely noticeable and can affect your performance.
For casual gaming and slower-paced titles, V-Sync is a perfectly reasonable option. For competitive gaming, most players avoid it.
The Better Solution: Adaptive Sync
Adaptive sync technology flips the relationship between your GPU and monitor around entirely. Instead of the monitor ticking along at a fixed rate and waiting for the GPU to catch up, the monitor's refresh rate becomes dynamic and follows whatever the GPU is actually delivering.
If your GPU is rendering 87 frames per second, the monitor refreshes at 87Hz. If it drops to 64fps, the monitor drops with it. The two are always in step, which means there's no opportunity for a frame to arrive mid-refresh and cause a tear.
This technology comes in two main flavours. AMD developed FreeSync, which is royalty-free and widely supported across a broad range of monitors at various price points. NVIDIA developed G-Sync, which uses proprietary hardware built into compatible monitors and tends to carry a price premium. More recently, NVIDIA also introduced G-Sync Compatible certification, which allows FreeSync monitors to work with NVIDIA cards, blurring the line between the two considerably.
If you're buying a monitor today and gaming is part of the plan, looking for adaptive sync support is one of the most worthwhile things you can do. It solves tearing without the stuttering and input lag penalties that V-Sync introduces.
What About Fast Sync and Enhanced Sync?
Both NVIDIA and AMD have released updated versions of their sync technologies designed to handle situations where your frame rate runs well above your monitor's refresh rate, a common scenario if you have a powerful GPU paired with a standard 60Hz display.
NVIDIA's Fast Sync and AMD's Enhanced Sync work similarly. They allow the GPU to render freely at high frame rates, pick the most recently completed frame at the moment of each refresh, and deliver a tear-free image with lower input lag than traditional V-Sync. They're a solid middle ground for high-performance setups where you're consistently exceeding your monitor's refresh rate.
The trade-off is that they work best when your frame rate is significantly and consistently above the monitor's refresh rate. If your performance is inconsistent or hovering close to the refresh rate, you may still see occasional tearing or stuttering.
Higher Refresh Rate Monitors Help Too
There's another, more straightforward way to reduce how noticeable tearing is, even without sync technology: a higher refresh rate monitor.
Tearing still technically occurs on a 144Hz or 240Hz display, but because each refresh cycle is so much shorter, any tear that does appear is gone almost instantly. At 240Hz, a refresh takes about four milliseconds. The tear exists for such a brief window that most people simply can't perceive it.
This is why many competitive gamers run high refresh rate monitors without V-Sync and without adaptive sync. At high enough frame rates on high enough refresh displays, tearing becomes a non-issue in practice even if it's still technically happening.
In-Game Settings That Make a Difference
Beyond sync technology, a few in-game settings can help manage tearing. Capping your frame rate just below your monitor's refresh rate using an in-game limiter or a third-party tool like RTSS (RivaTuner Statistics Server) reduces the chance of the GPU getting too far ahead of the monitor. A frame cap of 141fps on a 144Hz display, for example, keeps things close enough to minimise tearing without triggering V-Sync's drawbacks.
Some games also have their own built-in frame limiters and sync options that are worth checking in the display or graphics settings menu before diving into driver-level solutions.
Which Fix Is Right for You?
If you have an adaptive sync monitor, use it. Enable FreeSync or G-Sync in your driver settings, turn off V-Sync in-game, and let the technology do its job. It's the cleanest solution available.
If you don't have an adaptive sync monitor and tearing bothers you, V-Sync is a reasonable compromise for slower-paced or single-player games where input lag won't affect your experience. For competitive play, try a frame rate cap instead and consider whether a monitor upgrade makes sense down the line.
If tearing only appears occasionally and doesn't bother you much in practice, a higher refresh rate monitor will likely reduce it to the point where it's no longer something you notice at all.
Screen tearing is one of those problems that sounds technical but has practical, accessible solutions at every budget. Once you know what's causing it, fixing it is usually just a few settings changes away.
