Download-Android Tablet as External Monitor

I want a tablet solely to act as a small, USB-connected external monitor. I have two large screens, now want an additional, small one solely for system monitoring (temperatures, processes, etc). I see older android tables reasonable, eg under $70 for 9″ 2+ tablet. I’d like to configure the tablet start up with the app so nothing needs to be done but to turn it on – no further fiddling with touchscreen or tablet apps. Is such a thing practical (at a lower cost than equivalent small monitors, which are sometimes on sale for around $50 but otherwise seem incredibly to be getting – or asking! – $150 or so these days).
Most of these budget tablets will fail (either the battery or other component) if they run for 24×7 plus its practically impossible to run only some specific app on startup with Android OS.
Basically you want a device that acts as an plug and play monitor. That is actually a kind of data logger and specific systems are sold with proper connectivity options. They has just a specific OS and dedicated keys.
If its for home, honestly I think its better to refrain from wasting the money, ultimately it will become a junk like we all have lot of such “not used now” kind of electronics stuffs…
If the tablet is not being used 24/7 and only infrequently as a supplemental presentation device.
How can the tablet be cable connected to a laptop?
My need is to present 3D virtual models to client(s).
There may not be wifi available at these client meetings, so a cable connection is required.
Any suggestions or ideas?
