the width I wrote in mac is 100%, and the result is only 1620px. Then I want to buy a 1080p monitor and do something at 1080p resolution, and the display effect on pc is different from what I saw under 1080p. What caused this situation, and is there any good way to solve it?
sounds like a problem with high-resolution screens. To put it simply, things arranged on ordinary screens will be magnified on high-split-screen machines, while things arranged on high-score screens will shrink on ordinary machines. This is generally the operating system of high-split-screen computers, which is caused by setting DPI zooming.
my pc is a high-resolution screen (15-inch 1920x1080 resolution). For the convenience of development, I turned off the DPI zoom. Mac doesn't remember.
