The first questions: Why is the picture blurry

1. our screen resolution is 320*240pix , so the best picture size is 320*240pix, and it is normal to display 100% on the computer. If it is text, please choose a darker font and a thicker font, and adjust the brightness and contrast after the screenshot, because everyone's computer is different, so you need to adapt and try it yourself.

2.If the picture is relatively large, it must be cut into multiple pictures, and 320*240pix is the best. If you think the cut picture is too small, you can also cut it into a picture with a length of 4: 3, and 640*480pix is the best size, and then view it after zooming in, Sometimes you need to adjust the contrast and other parameters of the picture yourself.

3. setting - Display - Backlight Brightness - 5 is good

4. about the picture, the calculator without privacy film is better than the calculator with privacy film
