You need a monitor which supports such high resolutions, and then a GPU which supports it as well.

The pixel increase is four fold, but the resolution increase is two fold. For example if you double 480x320 you get 960x640 which is twice the resolution as 480x320, but the pixels are quadrupled.
I see what you are saying, but I think it won't work that way. If your texture had a single pixel at point (100,100) that was blue, and you doubled the horizontal and vertical, then to keep the image the same size, there would have to be four pixels that were now blue. If you could figure out which four, then the image should remain the same, as you say, but which four pixels would now be blue? Do you copy to the right and down? That would shift the total image. Do you take the single blue pixel that was at (100,100), map that to the new screen coordinates then average the pixels around that point? You can't simply say, "It was (100,100), so set (x,y) to that color along with the pixels around it.", because there would be nine pixels of that color rather than the four you need. If you chose only four of the nine, then the image would shift slightly in one direction or another. The latter is clearly preferrable to the former, but neither is quite correct, so it seems like there would have to be some distortion that would result.
I don't entirely understand your example -- if you take a 100x100 image and set it to fill a 200x200 picture box, every pixel in that image will be quadrupled automatically, you don't need to do anything about it. The very top left pixel, which might be blue for example, will now have a blue one to the right of it, to the bottom of it, and then to the bottom right of it.

What you'll see in that form is that the image becomes blurry, but when the resolution of the monitor is doubled, then there's four times as many pixels in the same area as one on the previous display, so even though there's four blue pixels, they're only talking up the physical size of one pixel on the old display. So you can't see a difference.

Does that make sense?
