Not true. 1920x1200 is 16:10. 1920x1080 is 16:9.
Regardless, PS2 games play natively at 4:3, or 16:9 if supported. Hence you can't make it fit a 16:10 screen fully while keeping the original aspect ratio (16:9 at best).
Also, the D3D internal resolution is.. well.. internal. It's sort of the native canvas resolution onto which the image is drawn, and then stretched to fit the required aspect ratio. If you select a resolution manually, it replaces the internal PS2 resolution (different per game, usually around 512x512 or 640x448, etc, but still stretched to 4:3 or to 16:9). You could set an internal resolution of 100x500 and it would still stretch to the proper aspect ratio on display (4:3 or 16:9), but will look ugly due to the very low res..
What you can do though, if you prefer to have it really full screen on a 16:10 AR (while distorting the original 16:9 image slightly and make everything look slightly too "thin"), is set the GS window aspect ration to "Fit to Window/Screen" (emulation settings -> gs window).
