If I understand the above, you just want to swicth the displays on and
off; not control any other parameter. In which case, why not just
switch the power?

This would be fairly trivial upto 8 channels by simply using the PC's
parallel ports to drive a couple of relays; there are a few utilities
that let you do exactly that; control each bit on the port. Beyond
that, you could use a PIC with lots of outputs, and connect it to the
PC over the serial port. The PC indicates to the PI(C what to do with
each i/o bit.
