I have a Mid-2009 MacbookPro 5,5 connected via a MiniDisplay Port to VGA adapter to an Asus PA246Q. I am getting scanning lines at the default 1920x1200. I have downloaded SwitchResX and tried to play with the settings to get something workable, and while it has got better, it is not yet spot on.
I also grabbed the manual for the Asus PA246Q which contains the specifications, and tried setting up a custom resolution in SwitchResX but it says that it is an invalid setting.
I have read through the SwitchResX tutorial posted here but can't quite get it perfect.
Any assistance would be appreciated.
