I haven't been following the forum too closely, but we seem to have
hundreds of Nextion displays on uBitx's, and zero incidents
of Nextion displays getting blown by a low supply voltage.
So to all those with a Nextion, I'd say don't worry about it,
but be mindful of the possibility if voltage to the Nextion is below 4.75v.
This could be a Nextion design issue, not a CYA issue.
For pretty much any other electronics, don't worry about physical damage
due to undervoltage at all.? Just unexplained behavior.

On-line ham radio information is full of myths, conjecture, and some outright
lies.? I suspect that you are correct about this being lawyer instigated CYA
(Cover-Your_A$$).

Of course the original 1602 LCD display is not harmed by low voltage
operation.? If a Nextion is this easily damaged then that manufacturer's
product? probably should be avoided.? It might be interesting if someone
with a variable voltage power supply and a few dollars to waste could do
the necessary testing of that particular Nextion brand and publish the results
so we could be aware of facts instead of having to rely on maybe mythical
characteristics.
