I have a dual G5 Powermac with a Radeon 9600 graphics card. I plugged in my Dell 19' lcd monitor via a vga cable (vga to dvi converter into the box). I am for some reason unable to change the resolution to anything other then 640x480, (in the system preferences > display box it doesnt show anything other then that setting). I have alread: -Reset the PRAM, and that did nothing. -Swapped out cards from another machine (same card) and that did nothing. -Tried different dvi-vga converters as well as vga cables, did nothing. -Tried different type of monitor, did nothing. The only thing i havent done is tried a dvi cable, since i do not have one. I cannot install the system updates since the license agreement box is too big for the screen so i cant click ok (nor can i tab and push enter for some reason). Also i cannot re install the OS since again, the dialogue box is too big and i cannot click the next button. Please help! Is there any solutions you guys might have? anything at all i am willing to try.
