Monitor buying advice needed

[PoorOldSpike]

Okay guys i hear what you're saying but i'm still not sure i understand some of the basics..
Look at this mocked-up pic below, CM looks great and perfectly normal on the square screen on the left, and notice the circle is perfectly er... circular..
But surely the same pic on a widescreen is going to be stretched out like the pic on the right isn't it, and look unrealistic?
Look at how the circle is crazily stretched out on the widescreen!
Are some of you telling me that the pic on the right looks fine and normal to you??
