Backlight strobing at its best?
By way of introduction, I would like to briefly explain the topic of motion blur. Motion blur is a visual effect that usually occurs when objects on a screen move quickly. It occurs because modern screens, especially LCD displays, cannot update their pixels instantly between frames. When an object moves on the screen, it leaves a trail or blur because the pixels take time to move from one position to the next. Motion blur can cause moving images to appear blurry or out of focus, which is especially undesirable in fast-paced action games or when viewing videos.
Backlight strobing, also known as motion blur reduction or frame stabilization, is a technology used in some gaming monitors to reduce motion blur. This technology aims to improve image quality in fast-paced games, especially in scenes with fast movements. The way Backlight Strobing works is that the monitor’s backlight flashes in sync with the screen’s refresh rate. This means that the backlight is briefly turned off between frames or high frame rate images (frames). This brief moment of darkness between frames serves to reduce motion blur by shortening the duration during which a pixel remains on the screen.
One way to test or evaluate the motion performance of a monitor – is the UFO test from Blur-Busters. And I can tell you, I have never tested any monitor as intensively as the XL2566k. Once again, I had to realize that my pictures taken with the Apple phone only partially convey what you perceive with your own eyes. I need a better camera. Because some probably already know that there are now monitors with 500 Hz and more. So it’s completely insane to record with only 240 FPS. Let’s see what can be done. But let’s get to the topic.
I have prepared a comparison between OLED and TN for you today. That means 240 Hz vs. 360 Hz. I’ll show you, in particular, what DyAc has to offer. We’ll look at three refresh rates with and without DyAc. This will be interesting. One thing up front, DyAc only works with fixed frame rates. VRR and DyAc does not work. I recommend DyAc from 144 Hz upwards.

I am aware of the fact that comparing OLED to TN is kind of unfair. The 240 vs. 360 Hz refresh rate alone is a bit of a limp. Still, you’ll see that OLED at 240 Hz is incredibly close to 360 Hz LCD TN. But when DyAc is active, you’ll see the true performance of the XL2566K. Then you’ll understand why the pros swear by this monitor.
Please note that I don’t own a highspeed camera. Anything beyond 240 Hz I can’t display as it looks in reality. But I can recommend you to get a second opinion. Please use the link here: Click!

Too bad, the 360 Hz shots don’t come across that way. But I think you can get a good picture. Here is the one to one comparison of the respective frame rates.
The essentials regarding DyAc :
- Improved motion blur: DyAc aims to reduce motion blur in fast-paced games. This means that fast movements and fast action in games are rendered more clearly and sharply, improving the overall gaming experience.
- Better target tracking: Especially in first-person shooters, the ability to accurately track the target is critical. DyAc helps keep the target object more visible when players are moving or aiming quickly.
- Reduced ghosting effects: DyAc also helps minimize ghosting and trailing effects that can occur during fast frame changes. This contributes to overall image quality and clarity.
Interim summary
BenQ has one of the best strobing technologies on the market with DyAc. The improvements in terms of motion blur are very good. Especially when you look at the improvement at 144 Hz. The decisive factor is that DyAc produces almost no crosstalk or double image.
A comparison to ULMB2 would be interesting here. Currently, ULMB2 can be found in the ASUS ROG Swift PG27AQN and the new 540 Hz PG248PQ. You can find comparisons on YouTube – just as a hint.
The killer for all LCD panels would be – at least in my opinion – if BFI (Black Frame Insertion, “strobing”) is used in OLED monitors. Because the almost instant response times of OLED panels, coupled with high refresh rates, can rival LCD panels running at 360 Hz even at 240 Hz. If BFI is added to that, then it becomes difficult for LCD panels!
