  I think they’re LCDs, where refresh rates are way less relevant

    wait why is refresh rate less relevant in LCDs?

      TFT cells in LCD panels hold the image for pretty long between refreshes so there is little difference between 60 Hz and 120 Hz. Yes, 120 Hz will allow for 120 fps but that/s not really relevant for basic GUI.

      Meanwhile, a 60Hz OLED panel is as flickery as a CRT TV because the LEDs only glow when being refreshed.

      With a 30Hz LCD panel, you might notice the direction the refreshing goes across the screen, and there might be a little less contrast, some inconsistency between pixels, and a soft moving gradient if this interferes with the backlight frequency (since most backlight is DC now, this problem only really manifests with reflective LCDs under flickery mains lights).

      Meanwhile, a 30Hz OLED panel would be seizure-inducing and unwatchable.

        that makes sense, thanks. i havent ever used an OLED display, so i just didn’t know about the differences
