No, I have not come across an OLED device that would not have PWM at all brightness levels.

Yes, they call it DC dimming when it only flickers very slightly every 60 or 120Hz.

So the flicker free marketing BS is just BS. The same thing with TV's they advertise as flicker free but there is the 120hz dip which does make my eyes go bloodshot, whereas a flicker free LCD tv does not.

If its pwm free at 100% brightness, you can keep hardware brightness at maximumlevel, and dim via software (Install F.Lux and control brightness by using Alt+PgDn & Alt+PgUp)

    Aquila LG oled tv's are native 10-bit. I don't know about laptop panels, but if they are also, there is a chance there is no dithering

      I don't have high hopes either, but we cannot know if we don't try and confirm that it really is flicker and temporal dithering free

      Does this help? It’s the galaxy s24+ next to Asus Zenbook Pro 14 Oled. UX6404vv.

      Below 60% it uses pwm at 240hz. Unlike the g14 that uses pwm at 960hz.

      Above 60% it uses dc dimming at 240hz, just like the g14. Why did they set the dc dimming at 240hz, i have no idea. They could’ve set it at 960hz right? So i guess the pwm at any brightness over 60% is equal to this zenbook. Hope it helps

      So is it 100% on that picture? They said at 100 it should be PWM free

        Maxx Asus ROG Zephyrus G14 2024 GA403U is it really this model?

          OLED screens always flicker because they are emissive, similar to CRTs there will always be scan line. An OLED can be PWM free, but still flicker at a frequency equal to its framerate. If you are sensitive to flicker you should be cautious of OLEDs.

              Seagull I know that. My question was, whether this particular OLED really does flicker or not at 100%

              This is what notebookcheck.net stated, so wanted to confirm. And I wonder where they have gotten the Oscilloscope picture to their review, if it actually flickers.

                  Seagull When I had Samsung galaxy S2, which was one of the first OLED screens, I could use it for hours and hours without any discomfort. I think it did not have PWM at 100% so I kept it always at 100%

                  So it is also possible to make and OLED that does not flicker.

                  I think the scan line is there Just to avoid burn in, not a technological necessity

                      Maxx were you able to confirm with anyone that it does not flicker?

                      Based on the reviews, the following OLED models have a good profile of dc dimming (good filling coefficient, low amplitude of flicker, and wavy pattern):

                      1. ASUS Zenbook 14 OLED UX3405
                      2. Asus ROG Zephyrus G14/G16 2024 OLED

                      These reviews need to be double checked, as I had two cases where they did not match the reality.

                      1. One was with Zenbook 14x where the review stated no flicker at highest brightness, but when I looked in the store it did flicker (well , there is a tiny possibility it was because the latest drivers were not installed, or different units have different matrix models installed, but still)
                      2. I actually can show two reviews publically available of the same laptop which state different flickering results:
                        ATNA56YX03-0 (ASUS Vivobook Pro 15 OLED (K3500) - good as per laptopmedia , but bad as per notebookcheck due to 60 Hz frequency even though the pattern itself looks not bad)

                      So I would also be curious to double check these notebookcheck reviews against some real user reviews.
