Doubt due to my ignorance.

High Hz on OLED produce excellent strobeless motion blur reduction with fast GtG pixel response. It is easier to tell apart 60Hz vs 120Hz vs 240Hz on OLED than LCD, and more visible to mainstream. Includes WOLED and QD-OLED displays.

Doubt due to my ignorance.

Post by Asdfw » 19 Mar 2025, 06:26

I had a 15-year-old IPS monitor and bought an OLED, an AORUS FO27Q2 240Hz, so I have no comparison with another OLED. When the camera moves steadily, the image looks perfect. When I start moving the camera faster, I feel like I see (I don't have the technical words to describe it) something like repeated images, and maybe I expected too much from 240Hz, but I thought it wouldn't be noticeable.

So, my question is: Is it normal to see more than one image when moving the cursor a bit fast?
The benchmark looks perfect, it's only when I move the cursor fast.

Yes, see:

OLED further accentuates it, because of its virtually instantaneous pixel response times. It was less noticeable on older LCDs because they would mask it somewhat with their slower response times (more commonly known as "GtG").

Only an infinite frame + refresh rate would fully eliminate the effect.

Thank you. That's exactly what I see! I think I'm sensitive to the stroboscopic effect. I enabled motion blur, and it improves the sensation quite a bit, but it gives me motion sickness. Hahahahaha!

Catch-22 :lol:

And yes, post-process motion blur techniques crudely mimic what would occur during rapid panning with near infinite frame + refresh rates, ironically.

Wait, what??

This looks like a big deal.

I was going to get an OLED TV, makes me wonder if Mini LED is going to be smoother.
