What’s the relationship between setting of screen display resolution and digital magnification?
Published:2014-04-22 16:00:59    Text Size:【BIG】【MEDIUM】【SMALL

Digital magnifications vary depending on a number of factors of display resolution set by the computer monitor or graphics.

The display resolution of a screen can be set by computer, and you can get different display pixel sizes accordingly. As the display resolution becomes lower, the size of the display pixel becomes bigger, and the same resolution image covers a wider area of screen. Sometimes you have to click the second frame to finish viewing the image, this means that you get a bigger image, but its poorer in quality.

Please refer to the table below:
