A good monitor would have a native resolution of 1920 x 1080

It depends on the size of the monitor, the resolution setting of it, whether the 12MP image is 4:3 (most compacts) or 3:2 (most DSLR's), and displayed as portrait or landscape.
To use an example, I'll assume the image is landscape and 4:3.
On my particular laptop computer that I am using at the moment, I have my screen resolution set to 1366 x 768. It is a 16:9 monitor (most common these days), 14 inch diagonally.
12MP is about 4000 X 3000.
Because the aspect ratio of my screen has extra width, I will ignore the width and just consider the height. Dividing the 3000 pixel height of an image by the 768 pixel height of my screen I get 3.90625. So viewed at 100% full screen 1/3.90625th of the image height would fit. My monitor display is 7 inches high. So to view the image at 100% at the same real world pixel density that my monitor is set to, I would need a monitor display that is 7 inches X 3.9 = 27.3 inches high.

There are no current monitors that have more than 2mp, so that is all they can display at once, no matter how large your image. You can look at it full size by looking at a portion of the image, but you can't fit 12mp in a 2mp area any other way.

It! Doesn't! Matter! I have pics taken with a 12 MP camera that fill my 24" monitor and look great. I have them taken with 7 MP camera that also look great. The 12 MP is a DSLR and the 7MP is an old point and shoot. They also look good on my old 19" monitor.

That's not possible to tell because of different size screens. Any viewer should be able to open a photo to full screen. But your screen could be larger or smaller than mine... difficult to tell.

Leah, please stop worrying about megapixels and ISO.
The cameras you are interested in (Canon and Nikon) will both give excellent results for what you want.
