Overdrive is one of the most misunderstood settings on a gaming monitor. Manufacturers call it different things, the highest level often looks impressive in a spec sheet, and the default is not always the best choice. Yet the right overdrive level is one of the cheapest ways to improve how motion looks on a screen you already own.
This guide explains what overdrive does, the two artifacts it trades between, and a simple way to choose a setting by eye.
Quick answer
- Overdrive speeds up LCD pixel transitions by briefly pushing a stronger voltage, reducing smearing in motion.
- Too little leaves blurry trails (ghosting). Too much creates bright or dark halos (overshoot, or inverse ghosting).
- The middle setting is usually best. The maximum level is often there to hit a headline response-time figure.
- Test at the frame rates you actually play at, especially with variable refresh rate turned on.
- OLED monitors generally do not need overdrive because their pixels already switch extremely quickly.
What overdrive actually does
On an LCD, each pixel changes brightness by twisting liquid crystals. That movement takes time, and some transitions, particularly between dark shades, are slow. When a pixel can't finish changing before the next frame arrives, moving objects leave a smeared trail behind them.
Overdrive is a trick to speed this up. The monitor temporarily applies a stronger voltage than the target shade needs, which makes the crystals move faster, then backs off before the pixel goes past its target. Think of it as stepping on the accelerator hard and braking just in time.
The challenge is that "just in time" is hard to get right for every possible transition, at every refresh rate. If the push is too gentle, pixels arrive late. If it is too strong, they overshoot the target and come back, which shows up as a visible halo.
What each brand calls it
The setting is the same idea under many names. Look for any of these in your monitor's on-screen menu:
| Menu label you may see | What it is |
|---|---|
| Overdrive / OD | Generic name |
| Response Time | Common label; levels like Standard, Faster, Fastest |
| Trace Free | Used on some ASUS monitors, often as a 0–100 slider |
| AMA | Used on some BenQ and other monitors |
| Normal / Fast / Extreme | Typical three-level naming |
Names vary between models even within a brand, so if you're unsure, your manual will usually list it under picture or gaming settings.
Ghosting vs overshoot: the two failure modes
Ghosting (too little)
A blurry, same-colored smear trailing behind moving objects. Common with overdrive off or on the lowest level, and very noticeable on dark VA panels.
Overshoot (too much)
A bright or dark outline, often a different color from the object, that trails or leads the edge. Sometimes called inverse ghosting or coronas.
Most people find mild ghosting less distracting than strong overshoot, because overshoot creates an artificial edge that your eye picks up as an extra object. So when in doubt, lean toward the slightly gentler setting.
The highest overdrive level often produces the fastest-looking number in a response-time measurement, but with noticeable overshoot in real use. It is not unusual for the recommended setting on a monitor to be one step below maximum.
How to choose the right level by eye
You don't need special equipment. A free online motion test, such as a moving-object or UFO-style test page, plus a few minutes is enough.
- Set your refresh rate first. Make sure Windows or your console is actually running the monitor at its maximum refresh rate. Overdrive tuning at the wrong refresh rate is wasted effort.
- Open a motion test with objects moving across different background shades, including a dark one.
- Start at the lowest overdrive setting and note the trail behind the moving object.
- Step up one level at a time. The trail should shorten. Watch for a bright or colored halo appearing.
- Pick the highest level without obvious halos on the backgrounds you care about. If one level looks clean on light backgrounds but haloes on dark ones, weigh which content you see more.
- Check in a real game you play. Pan the camera across a high-contrast scene and confirm it looks right.
Overdrive with G-Sync, FreeSync and variable refresh
Variable refresh rate (VRR) makes the monitor's refresh rate follow your game's frame rate. That is great for smoothness, but it complicates overdrive. A setting tuned for the maximum refresh rate can be too aggressive when the frame rate drops, because each frame lasts longer and the pixel has more time to settle, so the extra push overshoots.
Some monitors handle this with variable overdrive, adjusting the strength based on the current refresh rate. Many do not, and use one fixed setting. Practical advice:
- If your games run near the maximum refresh rate, tune for that.
- If you're shopping, look for "variable overdrive" in reviews and spec sheets, and consider OLED gaming monitors, which side-step the issue entirely.
- If your frame rate swings widely, test the overdrive setting at a lower frame rate too. A frame-rate limiter in your GPU software makes this easy.
- If a level looks fine at high frame rates but haloes at lower ones, step down one level. The small loss at peak frame rates is usually worth it.

How panel type changes the picture
| Panel | Overdrive need | What to watch for |
|---|---|---|
| IPS | Moderate | Usually tunes cleanly; mid setting is often best |
| VA | High | Dark transitions are slow; dark smearing can persist even with overdrive |
| TN | Low to moderate | Fast panels; overshoot appears quickly at high settings |
| OLED | Usually none | Pixels switch near-instantly; menu may lack the setting entirely |
VA panels are the ones where overdrive matters most and helps least. Their slow dark transitions can leave a dark smear behind objects moving across shadowy scenes, sometimes called black smearing. Overdrive reduces it, but rarely eliminates it, and pushing harder tends to add overshoot on other transitions.
OLED monitors are different. Their pixel response is so fast that blur on an OLED is dominated by how long each frame is held on screen rather than by pixel transitions. If clear motion is your priority and an LCD's ghosting bothers you, that is one of the genuine strengths of OLED.
Related settings that get confused with overdrive
- Motion blur reduction / backlight strobing (names like ELMB, ULMB, DyAc or MBR): flashes the backlight to reduce perceived blur. It is separate from overdrive, often dims the image, and may not work with VRR at the same time. Our BFI and strobing guide covers it, and if it matters to you, you can browse monitors with backlight strobing and compare which ones support it alongside VRR.
- Low input lag / game mode: reduces processing delay. Helps responsiveness, not blur.
- Sharpness: an edge-enhancement filter. Too high can create halos that look a bit like overshoot, so set it to neutral before judging overdrive.
- Dynamic contrast: changes brightness with content. Turn it off while testing so it doesn't confuse your judgment.
Quick reference
| Symptom | Likely cause | Try |
|---|---|---|
| Long blurry trail behind objects | Overdrive too low | Raise one level |
| Bright or colored outline on edges | Overdrive too high | Lower one level |
| Clean at high fps, halos at low fps | Fixed overdrive with VRR | Lower one level or cap fps higher |
| Dark smears in shadowy scenes | Slow VA dark transitions | Mid overdrive; accept some smear or consider IPS/OLED |
| Halo even on lowest setting | Sharpness filter | Set sharpness to neutral |
FAQ
Should I turn overdrive off?
On most LCD gaming monitors, no. Off usually leaves visible ghosting. A low or middle setting is typically better than off. The exception is if every enabled level shows strong overshoot on your monitor.
Does overdrive add input lag?
Overdrive changes how pixels transition, not how long the monitor takes to start drawing a frame, so it is not generally considered a source of meaningful input lag. Responsiveness is mainly about processing delay and refresh rate.
Why does my monitor's 1ms response time still look blurry?
Advertised response times are often measured on a favorable transition at the most aggressive overdrive level. Real-world transitions vary, and perceived blur also depends on refresh rate and how long each frame is held.
Do OLED monitors have overdrive?
Generally they don't need it, because OLED pixels change state extremely quickly. Some menus may still show a related option; check your manual.
Is overdrive bad for the monitor?
No. It is a normal operating mode designed by the manufacturer. Choosing a level is about image quality, not panel health.
The bottom line
Overdrive is a five-minute fix that many people never touch. Run your monitor at its full refresh rate, open a motion test, and step through the levels until trails are short and halos haven't appeared. For most LCDs that lands on the middle setting. If you rely on VRR and your frame rate varies a lot, check that choice at lower frame rates too.
