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. (edit: only applies if the screen goes black between refreshes, which I just learned OLED, unlike CRTs, doesn't.) Ideally 100 Hz or more. But the image (frames per second) does not have to change that often. For example, movies are 24 fps but 35mm film projectors are 72 Hz: they flash each frame 3x before advancing (using a three-blade shutter) because 24 Hz is seizure-inducing but using a unique picture for each refresh (72 fps) is expensive. Similarly, your OLED TV is 144 Hz when gaming at 144 fps (if you can afford that), when watching a 60fps gaming video or 24fps movie: the screen controller works the same all the time but the picture it's fed changes more or less frequently.
If an OLED screen refreshed at 1 Hz, ~~you'd see a line going down the display~~ edit: I learned about TFT OLEDs which don't do that. So it never goes below 60 Hz. However, the phone can reduce animation fps when the CPU can't keep up or to save battery. 1 fps is extremely choppy though, I don't know where OP got that. I did once use a phone capped to that framerate (via adbcontrol pre-Lollipop where the screenshot is transmitted over USB) and it was awfully non-responsive.
It's pretty silly 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. https://m.youtube.com/watch?v=54E3uUEryZM
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...
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?
I didn't find it too silly as it was in context. Just stating his job to contextualize his answer, it didn't feel to me like he was waving his resume around.
