Here is a link to the 2003 Hitachi Brochure re VirtualHD 1080p Processing:
It's at the bottom of the discussion re lack of 1080p on HDMI interfaces.

Note VirtualHD 1080p processing in my 2003 Hitachi 42-inch Plasma, which is 
capable of 1280x1024@75 fps on the VGA port (see attached brocure).

PS: Sears has the similiar Hitachi 42HDM12 Monitor (Alis 1024x1024) on sale for

I'm running an AVS poll on that very subject right now for those that 
recently got a 1080p display for Xmas, or wherever.  The results 
strongly suggest (against my expectations) that deinterlaced 1080i is 
superior.  Though the number of respondents is still small (30 with a 
1080p display).  See:

It is always a mystery to me why 1080i continues to do so well but it 
often looks better to me too.  But I don't have a 1080p display yet.
