Change Display Resolution Of Second Monitor


3 posts in this topic

Recommended Posts

Hey there,


This Problem is driving me insane.


I have two Monitors on my Nvidia GTS 220. The first one (1680x1050 @ DVI Port) is working fine. The second monitor (17" @ VGA Port) should have an resolution of 1024x768 BUT is working only at 720 x 400.


Soo the question is: How can i change the resolution of my second monitor? Whenever I'm trying to change the reso via the "osx system properties menu", the resolution jumps automatically to 640x480 (for both displays) and i have to restart to get the proper reso for my first screen back.


Any suggestions?


Im running Snow Leopard 10.6.3


Kexts concerning Grapihc Card installed (Maybe this helps finding a solution):

You must make a dualmonitor configuration. Go to system preferences-->Display-->Disposition (I think,I've Italian version) the second menù and the you have to drag the white line on the second monitor (it will bethe primary monitor)

sorry for the english... :P


Thanks for the reply, but this is not my problem.
