As seen in the image, trying to have the 2 displays side by side creates this problem. There is a 2048x2048 box limit. My question is, what creates this limit and why. What would happen if I try with 3 displays or with 2 huge ones. Even better, what would happened if I tried a single monitor at resolutions of 2560x1600 or 2560x2048.

I see that it says "Hardware Limit". Does it mean the limit is made by the video card, all video cards, a specific monitor/tv or all monitors/tvs. This has always crossed my mind many times and since we are almost finished with 2011 (Happy Holidays and Happy New Years to all) I wanted to kick this doubt out of my mind so if someone else asks I can tell them.
