Typically with your motherboard you will get something called an "SLI BRIDGE". If your motherboard has more than one PCI slot all you have to do is plug in each graphics card to each PCI slot, then use the SLI bridge on the front of the two cards and connect them together. The SLI bridge looks like a short, thin, and wide "cable".(I put it in quotations because it doesn't look like your average cable, lol.) Also, whatever you put into your computer will all be on the same monitor, regardless of how many of what item, as long as it's in one case. The only other reason why it wouldn't be on the same monitor is if you added an extra monitor to provide as an additional screen.

With SLI/CF, you just connect one GPU to the monitor (the primary one, in the PCIe slot nearest to the CPU). The other GPU is used in 3D games with SLI/CF enabled and when the game supports it. Meaning, you only know the second one works because you can configure it with the graphics drivers.

Without SLI/CF, this is pure lunacy and fundamentally ill-posed as the second GPU could never contribute to anything except cryptomining.

If you have two SLI bridges or one it doesn't make a difference. Either way works, whatever floats your boat.

Also, you only need one HDMI/DVI going from your top graphics card to your monitor, and that's pretty much it! If you think about it, the top GPU is the commander of the other GPUs, everything connects through him/her. Hope this helped!
