The system of all-in-one machine can be divided into Windows and Android. FanRuan officially recommends the Windows system, which does not need special debugging of the template. The resolution of Android device is usually inconsistent with that of browser rendering, so it is necessary to debug the template. If an all-in-one machine is used, it is recommended to use it by means of PC signal projection.
