Ok, I had a look into this again.
It works for me now on my native resolution 1920*1080! :D
I can select this resolution (and many others) from the game's options menu.
What caused the game not to show most resolutions was that I ran it with Windows 98/ME compatibility.
I use a tool called "
_inmm.dll setup" to re-enable the CD audio tracks which have been removed due to the no-cd feature of the 1207 patch.
In the installation instructions I found somewhere, it was mentioned to activate compatibility, however it works for me fine without it.
