Why does Blank Screen not work on my remote computer?

Follow

With the new technology to blank the remote screen, there is not a driver installation needed and it will work in most of the cases, except for some limitations listed as below.

  • On Windows 10 v1903 machines, a system reboot or display change (e.g., change resolution or disable/enable display) might be needed before it can work.
  • Will not work on some computers with gen 1 or 2 Intel CPU which still with HD graphics
  • Will not work on some computers with a monitor connected using a USB port (e.g., USB to VGA switch), installing the driver of the switch might resolve the issue.
  • When connecting to a computer which just woke up from Hibernate/Sleep state, it will not work at the first connection. It should work going forward.
  • Switching Windows users or logging off/in a Windows user during a remote session will turn the remote screen on then back off again.
  • Some display auto-adaptation software might turn the remote screen back on, e.g., f.lux, Asus Splendid Eye Care (a built-in software with Asus laptop).
  • On Windows 10 v2004 machines or later, there are three other limitations:
    1. On the physical Streamer side, the remote cursor is visible.
    2. Moving the mouse cursor to the taskbar thumbnail to preview will make the whole screen visible.
    3. Invoking task manager or security-related component with Ctrl+Alt+Del will temporarily disable blank screen.
