Why It’s a Game-Changer
-
Bigger is better: Ditch the small screen strain. View your apps, notes, scripts, or media at a size that’s easy to read and present from.
-
Any app, your way: Keep using your favorite lyrics app or teleprompter software, everything works as it does on your device—just bigger.
-
Professional polish: Perfect for musicians who prefer a particular app, speakers, podcasters, or content creators who need to enlarge the size of their device.
-
Plug-and-play simplicity: No complex setup or additional software required. Just connect, turn on the mirror mode, and you’re ready to roll.
How It Works
-
Connect your device – Plug your smartphone, tablet, or laptop into the included USB-C to HDMI adapter.
-
Send the signal – Run the HDMI output into the capture card.
-
Duplicate display (physically mirror) to the BLACK BOX Prompter – The capture card delivers your device’s screen to the prompter via USB.
-
Enjoy the upgrade – Your apps, documents, or presentation tools appear enlarged and crystal-clear on the 24″ display.
