Axim WM5 A02 external display resolution

[apeternier]

Dear all,

I just updated to the last version (A02) of Windows Mobile 5 on my x50v.
Unfortunately, they modified the external display resolution used when system/mirror is activated (before was 800x600 (A01), now is 1024x764).

Do you know if there's a way to modify the default external resolution used when mirroring is activated? Some registry keys to change?
I really need to switch back to 800x600 because of some (stupid) limitations of my external display connected with my Axim (through their Presentation Boundle adapter).

Thanks!
