DyAc vs. G-Sync: The Technical Clash Between Backlight Strobing and VRR
DyAc: Master of Motion Clarity Through Backlight Strobing
DyAc, or Dynamic Accuracy, is BenQ ZOWIE’s proprietary backlight strobing technology. It’s engineered for one crucial purpose: obliterating motion blur.
In fast-paced games, blur can obscure enemy movement.
DyAc addresses this by rapidly turning the monitor’s backlight on and off between refreshes.
This brief darkness “resets” your eyes, reducing the persistence of vision effect.
The result is incredibly sharp images, even during rapid camera movements. For FPS pros, seeing enemies crystal clear during a flick shot is a game-changer.

However, this intense clarity comes with a trade-off.
Backlight strobing can reduce overall screen brightness.
Some users might also perceive a slight flicker, though this varies greatly by individual.
DyAc excels in competitive scenarios where every pixel of clarity matters. Think Valorant, CS:GO, or Overwatch.
G-Sync: The Variable Refresh Rate Champion
NVIDIA G-Sync is a Variable Refresh Rate (VRR) technology. Its mission is to eliminate screen tearing and stuttering.
Screen tearing happens when your GPU renders frames faster or slower than your monitor’s fixed refresh rate.
G-Sync synchronizes your monitor’s refresh rate directly with your GPU’s output.
This ensures that each frame is displayed completely before the next one appears.
The result is buttery-smooth gameplay, free from visual artifacts that can distract or disorient you.
Unlike DyAc, G-Sync’s primary focus isn’t motion blur reduction.
While a higher, consistent frame rate inherently feels smoother, G-Sync doesn’t actively strobe the backlight.
One of G-Sync’s key benefits is maintaining optimal input lag.
It generally adds minimal, if any, latency compared to V-Sync.
V-Sync, for example, can introduce significant delay.
The Technical Showdown: DyAc vs G-Sync
Let’s break down the core differences between these two titans:
| Feature | DyAc (Backlight Strobing) | G-Sync (VRR) |
|---|---|---|
| Primary Goal | Reduce motion blur | Eliminate screen tearing & stutter |
| Mechanism | Rapidly strobes backlight | Synchronizes monitor refresh rate with GPU frame rate |
| Motion Clarity | Significantly improves | Indirectly improves by maintaining smooth frame delivery |
| Tearing/Stutter | Does not directly address | Completely eliminates |
| Brightness | Can reduce screen brightness | No impact on brightness |
| Flicker | Can introduce perceived flicker | No flicker introduced |
| Compatibility | BenQ ZOWIE monitors only | NVIDIA GPUs & G-Sync compatible monitors |
Choosing Your Weapon: Clarity or Smoothness?

The Performance Penalty: Comparing Brightness Reduction and Input Lag Trade-offs
When you’re pushing for peak performance, every millisecond and every visual detail matters.
Both DyAc and G-Sync offer distinct advantages for motion clarity, but they come with their own performance trade-offs.
Understanding these penalties is crucial. It helps you decide which technology aligns with your competitive edge.
DyAc: The Brightness Trade-off for Crystal Motion
DyAc, or Dynamic Accuracy, uses backlight strobing to reduce perceived motion blur.
It rapidly turns the monitor’s backlight on and off in sync with the refresh rate.
This technique effectively eliminates blur, making fast-moving objects appear sharper. However, there’s a significant drawback: brightness reduction.
Because the backlight is off for a portion of each refresh cycle, the overall perceived brightness of your screen decreases.
This can make darker scenes harder to discern.
For example, some monitors can see their peak brightness drop by nearly 30% when DyAc is active.

While the enhanced clarity is a major boost for games like FPS titles, you might find yourself struggling in dimly lit game environments.
The input lag introduced by DyAc is generally minimal, as it’s primarily a display-side processing technique.
Your focus here is on the visual clarity versus overall screen luminescence.
G-Sync: Balancing Smoothness with Potential Input Lag
G-Sync technology provides a variable refresh rate (VRR) experience. It synchronizes your monitor’s refresh rate with your GPU’s frame output.
This eliminates screen tearing and stutter, delivering an incredibly smooth visual experience.
However, G-Sync can introduce a slight increase in input lag compared to having VRR completely off, especially if not optimally configured.
For competitive gamers, understanding response time vs. input lag is critical.
While G-Sync’s input lag is often very low, typically just a few milliseconds, every bit counts.
The added latency is most noticeable when your frame rate is significantly lower than your monitor’s maximum refresh rate.
If you keep your FPS capped just below your monitor’s max refresh rate, G-Sync offers tear-free visuals with minimal lag.
Unlike DyAc, G-Sync has no direct impact on your display’s brightness levels. It focuses purely on frame synchronization.
The Trade-off Matrix: Which Penalty Can You Afford?
Choosing between DyAc and G-Sync involves weighing their respective performance penalties against your gaming priorities.
Do you prioritize maximum brightness or absolute minimal input lag?
| Feature | DyAc (Backlight Strobing) | G-Sync (Variable Refresh Rate) |

The Decision Matrix: Why Framerate Stability is the Ultimate Dealbreaker
You’ve seen the tech specs, debated the milliseconds, but here’s the ultimate truth for competitive gamers: framerate stability is your ultimate dealbreaker.
Raw FPS numbers are great, but inconsistent frames can sabotage your motion clarity.
Imagine your aim is dialed in, your DPI is perfect, and your reflexes are razor-sharp.
But if your framerate is jumping all over the place, your display can’t keep up.
This leads to perceived stutter and tearing, which disrupts your focus and ruins that crucial split-second reaction.
Both DyAc and G-Sync tackle motion clarity.
They operate under different assumptions about your framerate.
Understanding this difference is key to dominating your opponents.
DyAc: The High-Performance Requirement
DyAc, or Dynamic Accuracy, uses backlight strobing to reduce perceived motion blur.
It is incredibly effective when your game’s frames per second (FPS) consistently matches or exceeds your monitor’s refresh rate.

Think of it as a precision tool.
If you can maintain a rock-solid 240 FPS on a 240Hz DyAc monitor, you’ll experience unparalleled clarity.
Every pixel transition is crisp, giving you a distinct advantage in tracking fast-moving targets.
However, if your FPS dips significantly, DyAc can introduce noticeable artifacts like inverse ghosting or double images.
It expects a consistent, high frame delivery.
G-Sync: The Adaptive Solution for Variable Performance
G-Sync, NVIDIA’s adaptive sync technology, shines when your framerate isn’t perfectly stable.
It synchronizes your monitor’s refresh rate directly with your GPU’s output, frame by frame.
This means no more screen tearing, minimal stutter, and a dramatically smoother visual experience.
This holds true even when your FPS fluctuates between, say, 120 and 180 on a 144Hz monitor.
G-Sync adapts to your system’s real-time performance.
The trade-off? G-Sync primarily focuses on eliminating tearing and stutter.
While it improves overall smoothness, it doesn’t reduce motion blur in the same way backlight strobing does.
You’ll still see some inherent motion blur, though it’s less distracting without tearing.
Choosing Your Weapon: Framerate Stability is Key
Your decision hinges on your system’s ability to maintain stable, high framerates in your primary games. Let’s break down the scenarios.
A bar chart showing perceived motion clarity: DyAc (Stable High FPS) is 95, G-Sync (Stable High FPS) is 85, DyAc (Variable FPS) is 50, G-Sync (Variable FPS) is 90.
As the data indicates, DyAc demands peak, consistent performance for its best effect.
G-Sync provides a consistently smoother experience across varying frame rates.
Your Personal Decision Matrix:
Use this matrix to determine which technology will give you the edge:
| Scenario | Your Best Choice | Why |
|---|---|---|
| Consistent High FPS (e.g., >200 FPS on 240Hz) | DyAc | Unmatched motion blur reduction for elite tracking. |
| Fluctuating FPS (e.g., 100-180 FPS on 144Hz) | G-Sync | Eliminates tearing and stutter for overall smoothness. |
| Always Hit Max Refresh Rate | DyAc (Optional: G-Sync) | DyAc for ultimate clarity; G-Sync still offers benefits. |
| Struggling to Hit Max Refresh Rate | G-Sync | Essential for a playable, tear-free experience. |
Don’t just guess your framerate stability.
Use tools like MSI Afterburner or NVIDIA’s in-game overlay to monitor your actual FPS performance across different games and scenarios.
You might be surprised.
Beyond monitors, optimizing every aspect of your setup contributes to stable framerates.
Ensure your peripherals aren’t introducing latency.
For example, a high mouse polling rate can help your input feel more immediate, aligning with your display’s output.

Visualizing Stutter Artifacts: The Consequence of Using DyAc During Frame Drops
You’ve optimized your rig for peak FPS, but even the best setups hit snags.
Frame rate consistency is crucial for competitive play.
When your frames dip below your monitor’s refresh rate, DyAc’s benefits can vanish.
Instead, you’ll experience frustrating visual stutter and jarring motion artifacts.
DyAc, or Dynamic Accuracy, relies on a fixed backlight strobing frequency.
This frequency usually matches your monitor’s maximum refresh rate.
When your game’s FPS drops, DyAc keeps strobing at that constant rate.
The monitor attempts to display frames that haven’t updated, leading to duplicate images or an uneven presentation.
This creates a highly distracting visual stutter.
Imagine your monitor is refreshing 240 times per second, but your GPU only sends 120 new frames.
DyAc continues its 240Hz strobe, effectively showing some frames twice.
This is a critical disadvantage in fast-paced games.
This inconsistency can break your immersion and, more importantly, your reaction time.
That micro-stutter could be the difference between a headshot and missing your target entirely.
Your muscle memory gets thrown off by unexpected visual hitches.
G-Sync and FreeSync tackle this by dynamically adjusting the monitor’s refresh rate to match your GPU’s output.
This synchronization eliminates tearing and vastly reduces stutter during frame rate fluctuations.
With adaptive sync, each new frame is displayed precisely when it’s ready.
The result is a consistently smooth visual experience, even when your FPS fluctuates.
This stability is key for maintaining focus and precision during intense gaming moments.
You need every edge you can get.
To truly understand how frame rate fluctuations impact visual performance, consider these scenarios with DyAc enabled:
| Scenario | FPS Stability | DyAc Behavior | Visual Artifacts |
|---|---|---|---|
| Stable High FPS (e.g., 240) | Matches Refresh Rate | Consistent Strobing | Clear, blur-free motion |
| Moderate FPS Drop (e.g., 180) | Below Refresh Rate | Strobes at Fixed Refresh Rate | Noticeable stutter, occasional ghosting |
| Severe FPS Drop (e.g., 100) | Significantly Below RR | Strobes at Fixed Refresh Rate | Pronounced stutter, double images, jarring motion |
A stable frame rate is paramount for competitive gaming. While DyAc excels at motion clarity when FPS is consistent, its Achilles’ heel is frame rate drops.
This is where G-Sync offers a superior solution, adapting to your GPU’s output. Don’t let visual stutter cost you games. Test your setup’s stability.
