Monitor went black

My G5 Dual 1.8 is usually hooked to an old 17" monitor with a max resolution of 1024x768. Over the weekend I took it to a friend how and used his 19" monitor at 1280x1024. I brought my G5 back and hooked it back up to the 17" It said that it recognized 1280x1024 @ 60kHz. So stupid me, I went to the display shortcut at the upperright corner and changed it to 1280X1024 @ 75kHz. Then my monitor went black. The sounds and buttons still work, but I don't see anything!



Everytime I restart I see the gray apple loading, but then the monitor goes black. I tried to zap the PRAM and removing my third-party RAM and it didn't work. I hooked up different monitors and they work and I hook the 17" monitor to diffferent computers and it works, however I need this monitor and this G5 to work together again!



Help!

    Did you try changing the resolution with another display hooked up? Seems to me that's the most obvious solution.



    And how can you stand to run OS X at 1024x768? I would die! I switch between 1280x1024 and 1600x1200 on my Cube on a 17" display. That resolution would drive me nuts.

    did you reset the NVRAM in Open Transport?

    can you start into single-user mode?

    I tried hooking the computer to another montior and switching the resolution down. That didn't work. I don't like working at 1024x768 either but the CRT is really old and holding out to buy a 20" ADC Display. 1024x768 is the max for the monitor. It sucks!



    How do you reset the NVRAM? Is that the same as holding option-apple-p-r at startup? I'll try the single mode startup.



    I did try a safe boot and it works. But when I restart, after changing resolution down, the monitor stays black. What do I have to change?

    Startup with option-apple-o-t keys (ot = open transport)

    type 
    Code:


    reset-nvram



    and hit return, then type

    Code:


    reset-all



    and hit return again



    it's like a PRAM reset but not exactly the same (?)
