The pro Block Screen Tool
BlockScreen redefines remote technical service. Black out the client's physical monitors during a session while you keep full, private control of the real desktop — fast, lightweight, one file.
Built for GSM & repair technicians
Work on a client's machine without an audience.
Invisible to your remote view
The black screen shows on the client's monitor but is excluded from screen capture — you still see the real desktop remotely.
Full click-through control
Your mouse and keyboard pass straight through the black screen, so you work normally while the client sees nothing.
Multi-monitor aware
Scan and blank any combination of the client's displays — leave one visible if you want.
One lightweight .exe
No installer, no dependencies. A single file the client runs, with your branding.
Instant restore
Bring every screen back with one click, or the Ctrl+Alt+M panic hotkey.
Custom wallpaper
Show your own full-screen image on the blanked monitors — set it from your account.
Three steps to a private session
Log in
Open BlockScreen on the client machine and sign in with your technician account.
Scan & apply
Detect the monitors and black them out — your remote view stays clear.
Work & restore
Do the repair in private, then restore every screen with one click.
