Throughout my years as a samsung customer, I have learned whatever their marketing dept said, just take it with a pinch of salt and interpret it as the opposite.

For instance, if they claimed a monitor is flicker-free, then it is not flicker-free. If they claimed their newest mobile chipset is their most power efficient to date, that usually means it is very resource hungry chipset.

Its really a psychological trick that would make consumer go “oh, despite its flaws however, according to the manufacturer, it is still better than the many competitors on the market”. When in reality, they are the among the worst offenders for what they claimed.

For instance, Samsung claimed they are a company that emphasized on eyecare. However, we all know that Samsung’s own flagship phone has the lowest pwm yet with the highest modulation (aka fluctuation) on the market.

Do stay away from Samsung like a plague if you value your eyecare. 

Abeabe I concur with OP that something appears to be very wrong here and it doesn't just look like PWM as captured by a rolling shutter camera. At a guess if what it could be. I do recall the Neo G7 monitors are known to contain local dimming and other image/backlight "processing" functionality as an option, so assuming it has the potential to be "safe", try taking a look at the options.

      JTL I already returned the monitor, what I recorded was the first screen that appears as soon as you turn it on, from what I have seen on Samsung televisions these flicker at different frequencies depending on the image processing they are doing and a desktop monitor is not a tv, so it should never flicker and even more so if it is advertised as flicker free, or al least it should not be flickering by default, it looks like a tv disguised as a monitor.

      • JTL replied to this.

          Abeabe Can't say I'm surprised. I'd say you made the right decision.

            I don't know about NEO G7 43", but other 43" "monitors" have panels derived from television stock and suffer from issues such as the nonsensical inverted "BGR" pixel layout.

              JTL Yes, I had the gigabyte Aorus fv43U monitor with BGR pixels, the text on it looked terrible, curiously I couldn't detect any pwm flickering on that monitor with my camera, but it made me dizzy anyway and I also had to return it.

                Abeabe You got it all wrong. PWM looks like stripes only when recorded on camera, due to the shutter speed. Human vision is not scan based, and it always percepts the PWM as a whole frame flickering. So yeah, I do not need any schooling from people who have only basic understanding of the problem , as I myself had a panel with pixel inversion problem (https://www.displayninja.com/pixel-walk-pixel-inversion/) and replacing it I do not have it anymore.

                    EyeDiscomfortCertificate Relax my friend I am learning, bear with me, unfortunately I only know three ways to detect invisible pwm flicker, with my dizziness and eyestrain, with a video camera and with an oscilloscope, I showed you what pwm looks like through videos because I don't know any other way to do it in an doable way, the stripes on that ninja pixel image, I think they exaggerated it a bit in order to explain their article since in it says that the pixel inversion artifacts could be stripes in a form of scan lines or color distortion, vertical lines etc, they are not as thick and they are not scrolling in the entire screen as pwm flicker, if you see them through a video camera. Personaly I can see pixel inversion artifacts with a naked eye, but I can't see a high speed flicker from pwm, I will give you an example with a youtube video of how I have seen the pixel inversion artifacts, to me it looks like the entire area is flashing when you intereact with the browser and pixels change their state, not like pwm scrolling lines that not needs user interaction, but that's my experience, I don't know yours and I don't know how you've seen them.
