Comment on Dell brings back XPS laptops — ditches the capacitive touch bar, adds 1Hz display option, and upgrades 14 and 16-inch models

  They might mean down to 1hz like some smart phones do, to save battery.

    There’s a 1920 x 1200 non-touch display option, which will surely get you better battery life than OLED. But what’s most interesting about it is the 1-120 Hz variable refresh rate, which Dell says is a first to for this model. That extremely low refresh should help save power when static images or text is on the screen.

    Ah yeah, I should have read the rest of the article. I didn’t know about that feature though, that’s cool

        Probably not as bad as you might think:

    That’s slower than a car blinker.

      1 Hz is 1 fps. Hertz = cycles per second

        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.

      No, I meant what I said. The article says “hz” and so do other phone manufacturers offering the same feature. It may be marketing wank or technically incorrect but that’s what it’s referred to as.

      But, hz of a monitor is not like a car blinker or CRT televisions where it’s off in between the updates. It is on in between the updates, it’s just not the new image. In which case it doesn’t matter how slow your performing the updates because the pixels are just on with a static picture in between the updates.

        Yes, it is on OLED, unless they’ve added active storage like TFT LCDs. In which case, that’s cool technology they’ve invented.

  It says 1-120 Hz in the article (for battery saving and e.g. ehen there’s static images on the display).
