Hi Keun Hyung

Hope you are doing well and sorry for the trouble. As described you are getting the black and white dots on the PDF file.

Please go through the correct answer marked in the similar discussion https://community.adobe.com/t5/acrobat-reader-discussions/screen-turns-to-black-and-white-dots-using... and see if that works for you.
