As Fast As Possible

Some gaming monitors offer motion blur reduction technology which can increase motion clarity by backlight strobing. You can enable this feature in the OSD (On-Screen Display) menu of the monitor; you will find it under different names according to the monitor model, the most common ones are ULMB, ELMB, 1ms MPRT, DyAc, LightBoost, etc.

Update: Added information about Blur Busters’ Certification Program.

So, you’ve got yourself a fast CPU, a powerful GPU, and a high refresh rate gaming monitor yet you’re not satisfied with the gameplay performance due to prominent ghosting or trailing of the fast moving objects on-screen.

The single best solution is a gaming monitor with motion blur reduction technology such as Ultra Low Motion Blur, LightBoost, BenQ DyAc, ASUS Extreme Low Motion Blur, 1ms MPRT, etc.

What Is Motion Blur Reduction?

In short, enabling motion blur reduction makes the display strobe the backlight in order to create CRT-like motion clarity which is ideal for competitive fast-paced games.

You can enable/disable motion blur reduction in the OSD menu of the gaming monitor. Different monitor models have different brand names for this technology including:

  • NVIDIA’s ULMB (Ultra Low Motion Blur)
  • NVIDIA’s LightBoost
  • BenQ’s DyAc (Dynamic Accuracy)
  • ASUS Extreme Low Motion Blur
  • LG’s 1ms Motion Blur Reduction
  • Samsung’s 1ms MPRT (Moving Picture Response Time)

NVIDIA’s LightBoost technology is outdated and only available on older monitors whereas ULMB is featured only in certain G-SYNC gaming monitors.

When Should You Use Motion Blur Reduction?

The quality of motion blur reduction will depend on many things including your system rig, monitor, video game, and picture/driver settings. In truth, enabling backlight strobing won’t always make the gameplay look smoother.

Games will look the best when your refresh rate is close or equal to the frame rate which can be difficult to achieve since most motion blur reduction technologies cannot work at the same time as FreeSync or G-SYNC variable refresh rate.

ASUS’ ELMB-Sync is the first MBR technology that can simultaneously run VRR and strobe the backlight. It’s available in gaming monitors such as the ASUS VG27BQ.

For gaming monitors without ELMB-Sync or similar technology, you can try out various different settings depending on the game and your PC rig.

Sometimes games will work better with VSync Off and sometimes with VSync On (or FastSync/Enhanced Sync).

If VSync On introduces too much input lag, you can try to manually cap the frame rate in video game settings.

Also, note that enabling motion blur reduction decreases the monitor’s brightness. Some backlight strobing techniques will have additional settings available including LightBoost and ULMB ‘Pulse Width’ which alter the length of the backlight flash/pulse.

Response Time Speed

The amount of motion blur will also depend on the panel type (IPS, TN, or VA). More precisely, on their native response time speed.

Basically, VA panels have the slowest response time speed of all panel types, so even if a VA gaming monitor has a high refresh rate and motion blur reduction, fast-paced games will have prominent motion blur.

TN panels, on the other hand, have the fastest response time speed, usually only 1ms which is why they are the most popular choice for competitive gamers. IPS panels are somewhere in-between the two when it comes to the pixel transition time.

Lastly, OLED panels have an even faster response time than TN’s. Moreover, they don’t use a backlight which further increases motion clarity. However, OLED gaming monitors are quite rare and very expensive at the moment.

Blur Busters Approved Certification

Gaming monitors carrying the ‘Blur Busters Approved’ certification are tested and tuned by Blur Busters and thus ensure high-quality performance of the monitor’s backlight strobing technology. The certification indicates the following:

  • Better color quality when MBR is enabled
  • Less strobe crosstalk (double-images)
  • Manually adjustable backlight strobing frequency
  • Upgradable via firmware
  • More refresh rate options at which MBR can operate
  • Better MBR operation at lower refresh rates for monitors with higher native refresh rates

The ViewSonic XG270 1080p 240Hz IPS display is the first gaming monitor to receive Blur Buster’s certification for their PureXP MBR technology.

In fact, many people are comparing the motion clarity of ViewSonic XG270 to the old (but gold) CRT displays such as the Sony FW900 when the display is set to strobe at 120Hz.
