Okay. So, this is possible. But my doubt remains. See below.

I’ll be using multiple monitors but my original doubt was this. If I am
not connecting a monitor to GPU output, will I not be utilizing its
power for (this) display?  Assuming, I have configured X to utilize all
the GPUs for number crunching. Should it make any difference where I am
connect the monitor? What will be the highest available resolution? Will
it depend on where I have connected?
