My computer displays a 4070 graphics card, and the Spacedesk view used on my Android phone was downloaded from Google Play because Amazon has been unable to install it. At this point, when the computer is connected to a display screen and a USB connection is used to connect the phone, the spacedesk view only displays the taskbar, and the rest is black. Even if the display screen is turned off, it cannot be solved. The only way is to unplug the cable on the graphics card.
