Yes... hope you didn't get that widescreen display thinking you'd be looking at FS9 all reformatted to widescreen w/o distortion. Even with a widescreen display, if the content is not formatted for it, you'll either have the horizontal stretching, black bands on the sides, or the top and bottom chopped off (which might work for FS, but you'd lose a lot of important stuff, even if you dragged your instrument panel up or whatever).
I'm an A/V installs tech, and I've often seen a look of disappointment (or horror!!) when the client realizes their boardroom PC output signal doesn't magically fill their new 16:9 plasma or projection screen without some distortion or masking on the sides... ("talk to our sales rep; I just install 'em")...Widescreen displays are for HDTV and movies shot in the 1.85:1 (16x9) or 2.35:1 (Cinemascope) formats, but I think there are other games out now that are formatted for widescreen.
But whatever- if you like to watch movies on your computer, being able to watch wide-format films without letterboxing, chopping, or compression might be worth the trade-off with FS9.
Here's a link to a fun, simple thing about aspect ratios, if you want to learn more:
