Yes. It's not possible in principle to have content that can be
displayed but not copied, unless the display device is totally locked
down against user access to the internals.

I know that there was such a plan at one time, to end the era of
user-programmable computers, and replace them with untamperable media
players. What ever happened to that modest proposal? Nothing good,
I hope.

It's getting there; there's nowadays a thing called HDMI, which is an
encrypted authenticate-both-ways link between the display card and the
monitor, and a thing called TCP which could be used in such a way as
to allow a program to assure, at a level protected by RSA cryptography
with the keys in tamper-proof hardware, that the device drivers it's
running on are ones that its authors trust.

The movie companies, as far as I can tell, think TCP+HDMI might be
means sufficient to allow their films to be played on machinery which
has current-computer levels of user accessibility with an acceptable
risk of the things being copied.

They are also messing about with tricks in the space between the
performance of movie projectors, the performance of the human eye and
the performance of consumer video cameras, so as to produce movies
which can be watched by humans in theatres but cannot be recorded on
normal video cameras.
