I know for sure that my question would be more appropriate for the HD section, but I'll ask here.
I can't configure the resolution in the HD mod. I've always played at 800x600, and in streams, you can see that people's monitors cover a larger part of the map, extending beyond the usual Heroes interface. But no matter how I try to adjust the settings, nothing works. I set the resolution to 1920x1100, and I end up with a small hero screen and everything else is just a gray frame :(
