Question 1

How do I use ScreenExtend?

Accepted Answer

Run it on your PC, scan a QR code (or open the URL) on any other device, and enter the 6-digit session code. That device becomes an extended monitor.

Question 2

Is my data secure?

Accepted Answer

Yes. Every session needs a one-time code to join, which you can regenerate anytime to lock out unknown devices, and the stream is encrypted.

Question 3

What resolution and refresh rate can it do? Can it game?

Accepted Answer

Each device goes up to 200% scale and 500 Hz. Gaming works if your network keeps up; heavy high-refresh video needs a strong connection. HDR is coming in a future release.

Question 4

How many devices can connect at once?

Accepted Answer

As many as you like; each one gets its own virtual display. Performance drops as you add more.

Question 5

How does offline mode work?

Accepted Answer

In Settings, start the hosted network with a name and password. Join that Wi-Fi on the other device and open the URL on the dashboard, no router needed.

Question 6

What data does ScreenExtend collect?

Accepted Answer

None is stored. Settings stay on your device; a session only exchanges what's needed to set up the connection, then it's gone.
