Is "Aspect Ratio Scaling" possible with ATT?

[Amilo-D]

That is one of the questions that been bugging me ever since i switch back to ATI after a year with Nvidia. Thit issue is quite important for people using wide-screens yet still like to play classic games (most classic isometric rpg with 800x600 as max rez)

Here's simple example of the issue:
You have LCD with native resolution of 1280x800 (16:10). You run a game that only supports 800x600 (4:3).

Now with ATI you have 2 options:
1- Game image is distorted and stretched around the screen to 16:10 aspect.
2- 800x600 is displayed in center of your screen (black borders around it) but that way you use only half of your entire screen space. [done by disabling stretch-to-panel option in drivers]

With Nvidia there is a 3rd option:
3- game is stretched vertically but doesnt get distorted. You see black bars on left and right but game image is touching upper and lower edge, thus utilizing maximum possible space. Appearing to be using 1068x800 pixels (4:3).



Is the 3rd option possible to impliment using ATT? Or is it hardware limitation or something?
