I have image1 and image2. Image1 is screenshot from the display 3800x1900 with a device scale factor 2.25. The second image2 is a screenshot from the display 1800x900 with a device scale factor 1.
When checked dimensions (resolution), it's almost the same. Yet the first image is twice as big as the second one at 100% when viewed through an image viewer. The size though is also almost twice as big. All over the internet they say the dimensions define the size, but the dimensions in this case is almost the same.
I'm trying to understand what drives that difference. Looking for a technical answer.
