Bug#992280: hdmi doesn't help

[Mike Perrin <mperrin@icehouse.net>]

I was wondering if the VGA connection might be part of the problem so I 
tried booting the netinstall iso with the monitor connected through the 
HDMI port. The result was identical to VGA: the selection screen 
appeared perfectly but both the graphical and text install options 
produced a shredded display at 1920x1200.
