Help to reset monitor resolution?
Greetings,
I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode.
I have reset the pram and tried booting in safe mode but that did not help me.
From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen.
Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?
Any ideas would be much appreciated
Thanks
Gareth
