What is DyAC™ and DyAC+™ ?

In CS:GO, 80% of all shots require some level of recoil control.

DyAc™ /DyAc+ ™ is a technology designed by ZOWIE to reduce motion blur seen in LCD technology. It reduces vigorous screen shaking in-game and can help improve recoil control in CS:GO. Perhaps the difference is minimal and varies from person to person but the difference in the arena is often that 1%.

What is DyAc™?
Why you need DyAc™

Did you know that your monitor has “motion blur”?

The way a LCD (Liquid Crystal Display) produces an image is simple.

Each pixel becomes visible when a light beam passes through the liquid crystal. When we see an object continuously moving on screen, this means that light beams are continuously passing through multiple liquid crystals. Motion blur occurs because the liquid crystals are unable to close quickly enough resulting in the previous image still being visible momentarily.

Motion Blur

Despite higher refresh rates and the development of low-latency panels, the sharpness of moving images on LCD is still limited.

Among the multiple display technologies of the past, CRT displays perform the best in terms of moving images' sharpness. CRT creates images with electron beam tracking, so a moving object does not have an afterimage.

Dynamic Accuracy

DyAC™ / DyAC+™ is the exclusive technology that simulates CRT's dynamic display effect on LCD and it based on the backlight control technique. This is just an illustration and is not an exact representation.

DyAc off, DyAc on

The backlight is turned on and then switched off at a fixed point. This helps to avoid unwanted afterimages since there is no residual light from a previous fixed point. In other words, you do not see a lingering image (motion blur) because there is no light beam passing through more than one point at a time.

Previously, the LCD panel was a standard component. ZOWIE customized the panel and also made exclusive modifications to the circuitry and firmware settings. Without changing the content of games, DyAC™ / DyAC+™ provides clearer moving images, especially for FPS games.

How does DyAC™ / DyAC+™ help in CS:GO

DyAc™/DyAc⁺™ makes vigorous in-game actions such as spraying less of a blur. Both DyAc™ and DyAc⁺™ provide spray control with only differences on the panel specifications.

This allows gamers to see the position of crosshair and impact points more clearly which can help with recoil control.

The following videos are an actual slow motion in-game clip. The effect will still vary depending on the individual.

How does DyAC™ / DyAC+™ help in Valorant

In Valorant, characters have their own set of abilities like Jett and fast moving. When aiming and crosshairs moving, DyAc™/DyAc⁺™ makes background to be seen with less of a blur; and that helps with aim.

The following videos are actual slow motion in-game clips. The perception will still vary depending on the individual.

How does DyAc™/DyAc⁺™ help in APEX

In APEX, players can quickly change position with momentum shift or wall jump and characters have their own set of abilities for fast moving like Octane shown in the video. When aiming and moving the crosshair, DyAc™/DyAc⁺™ makes the background be seen with less of a blur when moving quickly, that helps to see the enemy more clearly, thereby helping to target the enemy The following videos are an actual in-game clip. The effect will still vary depending on the individual.


Q1: Will DyAc™/DyAc⁺™  increase input lag?

A1: The DyAc™/DyAc⁺™ won't add input lag, since it doesn't add any extra loading to the image processing to the monitor nor to the computer.


Q2: Why the brightness drops when I turn on DyAc™  on my XL2411K?

A2: This is due to the 144hz panel limitation. This phenomenon won't happen on our 240hz with DyAc™ models.


Q3: How much the brightness will drop when I turn on DyAc™ on my XL2411K?

A3: It is roughly 50% off, and the perception to the brightness drop may be different depending on each one's feeling and ambient conditions.


Q4: Is DyAc™/DyAc⁺™ compatible with GSYNC/FreeSYNC?

A4: DyAc™/DyAc⁺™ is not compatible with GSYNC/FreeSYNC, so when you turn on GSYNC/FreeSYNC (if your model has one of those variable refresh rate features), then the DyAc™/DyAc⁺™ will be off automatically; If you want to turn on DyAc™/DyAc⁺™, you need to turn off GSYNC/FreeSYNC through your graphic card control panel. The way DyAc™/DyAc⁺™ works is different from those variable refresh rate technologies, and DyAc™/DyAc⁺™ provides different benefits compared to the others:

• DyAc™/DyAc⁺™ provides a clearer dynamic vision based on a high and stable refresh rate and fps

• Variable refresh rate (GSYNC/FreenSync): reduces stuttering and tearing when there is a significant gap between fps and refresh rate, or it is under a low fps and refresh rate


Q5: Does DyAc™/DyAc⁺™ work on console or does PC need special requirements to be compatible with DyAc?

A5: DyAc™/DyAc⁺™ is an independent feature built into the monitor that can work on any PC or console but DyAc™/DyAc⁺™ will be only active when the input content is 100hz or above.
