Hi Ben
I have been looking for a tablet with HDMI input to use as an extra monitor when needed.
look on the internet i see alot of people looking for the same but as film monitor or photo monitor when traveling and taking photo.
the idea would be like taking an tablet with a resolution fitting hdmi signal like 720p or better 1080p, adding a hdmi connect to the screen cable with a switch to switch between tablet use and monitor use.
Yours
Jesper
