Greg the screens come in various sizes and resolutions , but the 5 inch
screens seem to be 800x480.
The touch functionality comes through unspecified GPIO connections, but
I can see it is the 26 pin connector they use.
And they admit the screen can be used as display only ( no touch ) by
any host, but forget to mention how it would be powered then, probably
the micro USB.
Not sure if links to commercial sites are allowed , but searching for
'raspberry lcd hdmi' on ???express gives you a few on the first page.
There is even a 3.5 inch version with audio out from HDMI but it poses
me more questions on the actual connection to the pi as they mention SPI
as alternative for HDMI. 
I need to learn a bit more, 
All this give me options to build something small without needing to
code. I am happy with PCP as it is serving me well.
