I have a Dell M1530 laptop with a Geforce 256 MB video card that has an HDMI connection. When I had Windows Vista installed on there, I would connect it to my Samsung LCD TV and almost no part of the desktop would get cutoff. However, now that I installed Windows 7, I am getting significant cut-off even though my resolution is the same (1920 x ??) and I have the latest drivers... Anyone have any ideas on how to fix this?
