"The reference pixel is the visual angle of one pixel on a device with a pixel density of 96dpi and a distance from the reader of an arm’s length. For a nominal arm’s length of 28 inches, the visual angle is therefore about 0.0213 degrees. For reading at arm’s length, 1px thus...

images are in a sense the worst-case scenario for image compression: they’re all headers and overhead, and very little data. And the very little data there is cannot really be compressed because compression depends on predictability, and how are you supposed to predict one single pixel?
There’s no need, and it’s a big energy drain. It’s far from a perfect example, but PC Perspective showed how one gaming monitor, with a 165Hz refresh rate, couldmore than double the power draw from a gaming computer. Apple says it can lower the Apple Watch refresh rate from 60Hz...
