About this app

Run the Byscreen program on your PC, plug the tablet in, and the tablet joins Windows as one more monitor. Keep chat or notes open on it, or drag windows across.

■ Connecting
· USB cable: the lowest delay. Turn on USB debugging on the tablet once.
· Wi-Fi: no cable when both are on the same router. The first time, check that the number on the PC matches the tablet and allow it.

■ Screen
· Extend: the tablet is added as a new monitor. Move it around in Windows display settings.
· Duplicate: show one of the monitors you already have.
· Pick 30, 60, 90 or 120 frames per second, as far as the tablet's screen goes. You can change it while you use it.

■ Pen and touch
· Pen pressure and palm rejection
· Trackpad mode: move the mouse pointer with your finger
· Shortcut bar with undo, copy, paste and keyboard buttons

■ Price
Everything works for the first 3 days. After that, 30 frames per second stays free; one purchase removes the frame limit. No ads, no subscription.

■ What you need
· A Windows 10 (2004 or later) or Windows 11 PC
· The PC program, from noveriq.co.kr/byscreen/en/
· A USB cable that carries data (charge-only cables don't connect)

The picture only travels between your PC and your tablet and is never stored anywhere.
Use your Android tablet as a second monitor for a Windows PC, over USB or Wi-Fi.
