What do small plug-ins 5X 1, 4X2 mean?

Some softwares (such as weather and clocks) have small pendants that can be hung on the desktop. 5x 1 and 4x2 are dimensions. Previously, the screen was small and the resolution was low. If the screen is divided into 4x4 blocks, the 4x2 pendant will occupy half of the screen, and 4x 1 will occupy 1 of the screen. Now when the screen is big, 5x 1 will appear, which is divided into four parts. It also solves the problem that some 4x4 screens are unoccupied. The display effect of pendant 4x 1 is different from that of pendant 4x2. If you like, you can put it on your desktop for easy viewing (such as a clock). Hold the pendant and drag it away to delete it.
