I'm sure that you can use a tablet for a virtual keyboard and/or a
touchpad component of a desktop computer, but that's not what I'm
asking about.

What if all you have is a tablet and big monitor. Of course what
you see on the tablet screen can be sent to the monitor with a
cable or wireless.

But...

Can you use a tablet as a virtual keyboard and/or a touchpad while
displaying the contents of the tablet, the GUI output part like
windows and dialogs that we interact with, on a PC monitor? The
idea is to make better use of the tablet touchscreen while using
the PC monitor as if it were connected to a PC. Preferably for
Android, but curious to know if it's been done on an iPad.

It might be tough to do since the iPad/Android touch interface
uses the whole screen of the tablet. Functioning as a touchpad, it
would control a pointer like on a PC, so you would have a pointer
moving around on an iPad/android GUI, which is even more involved.
Yet I have seen what looks like a pointer on an Android GUI, maybe
that's related.


If your tablet has an HDMI port, you can connect it to an HDMI
monitor/TV. The monitor or TV will display exactly what you see on the
tablet's screen. If you pop up the onscreen keyboard on the tablet, it
will show on the monitor/TV also. Since the onscreen keyboard usually
takes up a bunch of space onscreen, it will do the same on the monitor/TV.

I don't know of any way (and don't think there is a way) to
simultaneously display different output on the monitor/TV than on the
tablet screen.

What I find works better is to connect the tablet to both an HDMI
monitor/TV and also a regular keyboard and mouse. I connect mine to a
wireless KB and mouse combo that share the same USB dongle. I plug the
USB dongle into the tablet and I now get a mouse cursor onscreen and can
type without having to display the onscreen keyboard. Works just about
like a standard computer that way. With my large-screen TV, I can sit
across the room and surf the web, watch videos, etc.
