I bought a Dell 2408WFP monitor that I want to use as an external monitor with my late 2007 macbook running OS X 10.5.7. The macbook is connected to the monitor through mini-DVI to HDMI adapter that is connected to the HDMI port on the monitor. The problem is that the maximum resolution I managed to get is 1920x1024 instead of the full 1920x1200. I even downloaded SwitchResX and tried defining a custom resolution 1920x1200@60Hz, but it doesn't show up in the list of active resolutions after the restart.
Any help resulting in the solution will be greatly appreciated.
