Does Dyac2 still pose potential harm to the eyes?

Everything about displays and monitors. 120Hz, 144Hz, 240Hz, 4K, 1440p, input lag, display shopping, monitor purchase decisions, compare, versus, debate, and more. Questions? Just ask!

Dyac sounds gross:
DyAc/DyAc⁺/DyAc 2 is designed to reduce motion blur in LCD displays. “DyAc”, which is short for Dynamic Accuracy, reduces ghosting in fast game scenes, minimizes screen shaking in rapid firing, and enables players to track enemies more easily.
Why would anyone want dynamic anything especially when it comes to the images displayed to the screen? It's either fast-as-possible-at-all-times, or there's intentional latency added as a feature. I can totally see Dyac causing eye strain due to your brain expecting consistency, and not frames delivered at the potential speed of an algorithm.

Funny how none of these modern marketing tricks come close to a basic CRT :lol:
Both the XG2431 and XL2566K heavily outperform CRT displays in terms of MPRT (total motion clarity)
This is without going into the topic of geometry issues, text rendering issues, physical dimensions, ambient temperature difference, lack of RAMDAC on modern GPUS (thus forced to live with added total latency) and emitted magnetic field which the modern CRT experience suffers from.

I have found interesting thing about DYAC2
Dyac2 is rolling scan BFI only at max monitor refresh rate.
Bellow it is combination rolling scan BFI+ classic whole screen BFI
