I know what hertz is, I’m en electrotechnician. The display’s refresh rate is measured in hertz, and has to be at least 40 Hz or you suffer from headaches and some from photosensitive epilepsy. But the image (frames per second) does not have to change that often. For example, movies are 24fps but 35mm film projectors are 72 Hz: they flash each frame 3x before advancing because 24 Hz is seizure-inducing but using a unique picture for each refresh (72 fps) is expensive.
That’s some pretty confidently incorrect posting. Most gaming displays these days have some flavor of adaptive sync available that adjusts the refresh rate to the content being displayed, and even before that there were film modes that set the refresh rate to the ~24 fps(or a multiple if it) that film content is at to avoid stuttering/tearing.
This is likely the bottom of the adaptive sync window and will only be used if the machine is idle
I edited it, I thought all OLEDs worked like this little one where the pixels turn off between refreshes. Turns out there are TFTs that keep them on. Thanks for teaching me this.
You may be an electro technician but you obviously don’t know what you’re talking about so it’s pretty irrelevant to through around credentials.
Here’s a video of an OLED TV updating in slow motion. The pixels are on in between updates so it really doesn’t matter how fast it’s updating it’s not going to cause headaches or any of the problems that we used to associate with strobing style displays.

What’s the deal with Lemmy being so abrasive all the time. Sometimes I think some of us should be put in time out with just hacker news for a month to teach us some manners…

TFT and OLED are completely different display technologies.

Do you disagree with me thinking it’s silly to through around credentials on the internet or just how I communicated it?
I did edit after posting to tone it down some but perhaps not enough?

Well, on some they aren’t.

That display is using BFI (black frame insertion) which is usually optional to reduce blur.
