+## Before we begin
+This page is about physical touchscreen monitors connected over HDMI/DisplayPort. These will most likely **not** work:
+* Wireless display projection
+* Apps for using tablets as a second monitor for PC (SpaceDesk, Duet, etc)
+* Local streaming services like Moonlight
+
+... so please stop filing bugs or asking questions about them.
