Do you need to create a one-screen display on the computer?

A few days ago, I made a one-screen display on the computer. After two days of struggling, I still didn’t make a one-screen display. The biggest problem with one-screen display is the value of computer resolution, which cannot be compatible with computer resolution.

If you want to display it on one screen, the display situation on each computer will be diverse. Large websites such as Baidu, JD.com, and NetEase do not have a one-screen display. In fact, there is no need to do a one-screen display on the computer side.
