1600 x 1200 resolution, is it possible

[nappysparks]

i ran the hack for the ATi 9550 agp graphics card for it to function (to the best possibility for now). For the most part, i have been using the 1280 x 1024 resolution. Is there a way that i can change the resolution to 1600 X 1200. Its a newbie question, but hey........... im just a web designer.

Cut and paste from this forum:

 

Edit the boot.plist file at sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and add the following:

 

sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist<key>Graphics Mode</key>

<string>1600x1200x32@75</string>

 

 

You can edit the file by dragging it to the Desktop and editing it with TextEdit, then dragging it back, answering the 2 resulting dialogs - Authenticate and yes to replace, then followed by using Disk Utility to repair permissions on the OSX partition.

 

Or you can do it via Terminal with this command:

sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

Which "hack" did you run? I would suggest you to install the final Callisto drivers. Go to the genious bar and the video problems sticky. Then you should be able to set the display resolution to the desired from system preferences.
