Hi everybody!

Here's the problem:


I can't set properly the native resolution (1920x1080) of the external monitor plugged to my laptop via vga cable. I installed switchresx, but if i set 1920x1080 it don't fit the monitor...it shows all moved to the right, leaving a huge black frame on the left, almost half of the screen..even if i push "auto settings" on monitor it won't fit properly.


What to do? :S


What to know:


Acer Aspire 7745g (internal display 1600x900, well showed without problems)


ATI Radeon MobilityHD 5650


HDMI Video works fine


My boot flags: PCIRootUID=0 // GraphicsEnabler= Yes // AtiConfig=Flicker (the only one that allow me to show properly hackintosh via internal display)


Bootloader: Chameleon
