The problem with the 16:9 aspect ratios and Aces High II has to do with field of view, as it pertains to DirectX. Most games use a 75 degree fielf od view (FOV). First person shooters are notorious for this.
It helps keep the frame rate up by cutting the distance shorter, faster for objects. To get to 16:9 aspect ratios, they simply switch to 90 degree FOV.
The wider the FOV, the father away the objects can be and still be detailed. Aces High uses a 90 degree FOV, by default. If you take it any wider, which you would have to do fir a 16:9 aspect ratio, then DirectX creates a fish bowl effect. It looks atrocious.

I detest LCD screens. They have yet to make one which can outperform a high end CRT. Unfortunately, you cannot get a high end CRT anymore. Damn shame too. I keep looking at the LCD crap and it is still crap. The best LCD models made are still far short of the quality of my CRT at home.
Now, I am pretty critical of monitors. I have seen what many consider good, and I consider it crap.
There is one thing an LCD cannot do that a CRT can. Produce precise color. It cannot be done on an LCD today. And it gets worse if you try it at different resolutions.
