Check if pen display shows HDMI display signal from other devices

Overview

Among other things that append display receives from your computer, it also receives a “display signal”. Display signal means essentially “video” - what you see on the pen display.

Normally your pen display will be connected to your computer that provides such a display signal via an HDMI connection.

But your computer can receive that display signal from any device that supports a display signal. For example an Xbox, PlayStation, a DVD player, another computer, and even some mirrorless cameras (example Sony FX30).

This is useful for several reasons.

- It allows your pen display to be used like a monitor or TV

- it's also good troubleshooting technique

Troubleshooting

if you're getting problems like one of these:

- Not seeing anything

- Odd Flickering

- Weird colors

- "No Signal"

Then connecting your pen display via HDMI to another device is very useful technique. Because it gives you a hint as to whether the problem is with the tablet itself or with your computer.

If one device does not work, try others.
