I am using Set Display Mode 1024, 768, 32 on a 4:3 screen. This opens a full screen and all works as it should.

However if I run the same game on a 16:9 widescreen, all is stretched lenghtwise.

Is there a way to set Set Display Mode to use 16:9 to have a correct pixel aspect ratio?

on my wide screen I can do :-

1024x768
1280x768
1360x768
1366x768

whether any of those value will work only trying will find out.

thanks a lot Dark Coder, works perfectly.

Now I just need to find the real aspect ration of the user's monitor (4:3 or 16:9) so that i can set my screen mode the right way.

Read the help files on it, it says screen width/height, so assuming your app is set to the user's desktop resolution or something they pick it's just a simple divide, but make sure it's a float divide and not an integer one, else you'll end up with a value of 1 all the time.

screen width/height will give the same result on 4:3 and 16:9 so its a bit more complicated than that!

for example my desktop pc monitor 4:3 is set to 1024x768, and my laptop 16:9 is also set to 1024x768, but obviously the pixel aspect ratio is different

I default my games in 800 x 600 (a fairly "safe" resolution) and then let the user pick an appropriate resolution from inside the game by way of a list of available resolutions in the options menu of the game.

That way those who have widescreen can choose wide screen resolutions.

A lot of widescreen monitors are actually 16:10 format. A common resolution is 1440x900.

If your laptop is 16:9 then your maximum resolution isn't 1024*768, it's probably 1280*720 or 1920*1080 so it's your fault for not setting it correctly, the aspect ratio is exactly width/height.
