I am going crazy. I have an LG :L246WP without an DVI only HDMI. (I use a DVI-HDMI cable) Trouble is when I installed Windows 7 Beta on my old iMac it worked perfectly hooked up as a 2nd monitor but with my new Mac Pro and GT 120 card it refuses to display correctly. Plus it keeps installing drivers for a 9550 and doens't see it as a GT 120. It cuts off the left portion of the desktop and I've tried every option on the LCD and in windows and nothing works. Oddly enough before it installs the 9550 drivers it fills the screen but once the NVIDIA drivers kick in POOF back to half-screen. If I hook it up using VGA it works just fine (although blurry). Has anyone else had a similar issue with the new GT120 Cards with HDMI monitors? PS. I also had a problem going from DVI-HDMI with OSX 10.5.6 as well. I had to use SwitchResX to force it into the native resolution of 1920x1200.
