My issue is from the PC-HDMI problem also, don't have an old monitor lying around :-(
Just swapping the HDMI cable for a standard VGA one seems to work around the problem.
 
So no fix in the pipeline? This problem is inherent to ALL of your games based on the EU3 engine.

I cannot think of a SINGLE series of games that simply do not work with HDTVs as moniters.

Not one.

I don't know how you managed to fuck this up so badly.
