How to merge 2 android tablet or phone?

Question

Android

There are 2 Android tablets.
You need to combine them in such a way that when you do something on one tablet, the same thing is displayed on the other. And vice versa.
What it's for:
There are 2 children in the back seat of the car. It is necessary to combine the tablets in such a way that when a cartoon is turned on on one of the tablets, the same thing happens on the other. In general, to make it look like a duplicated display mode in Windows.
Is this possible? Maybe there is a special software for this?

Answer 1

It won’t be very good, but you can try
. First, connect the devices to one wifi network, something tells me that an additional router connected from the car network will be better than an access point on one of these devices, but nothing prevents the experiment from being carried out.
Then, with any remote control, even the same teamviewer or anydesk or just vnc, connect in view-only mode to the leading tablet and run on it (you can disable sound transmission so that there is no cacophony).

Another option, tablets cannot receive miracast, but you can find a portable monitor (there are some that are tolerable from 3-4 tr., maybe a little more expensive if necessary with a battery), buy an hdmi dongle miracast / airplay for 600-1000r and share (duplicate) the screen of the leading android phone / tablet on this monitor, at a short distance it works without problems. Support for video transmission over the air has long been almost standard, but it is also recommended to check your availability before buying a monitor.
