hey people,
I've been using two benQ FP731 VGA screens running off my G5. About 6 weeks ago my right (aux) screen stopped working. I would get about about a second worth when powering the screen back on with the 'on' button before the screen would go blank.
I thought this was a faulty power input problem on monitor as I tried running my other screen into the DVI output that my aux screen was running off and it worked fine.
I've was making do with my 1 screen (putting off getting the other screen looked at) when i came back from a break from work and my main screen was doing the same thing. I borrowed a friends screen and tried running this off the card and nothing happened either.
We assumed this was a graphics card problem, or maybe a problem with the PMU (Power Management Unit) on the logic board, but we thought we would double check by running my screens off his PC, and they didn't work either.
I'm no computer expert by any means, and I have no idea what the problem could be.
Somebody told me that running the graphics output at 75Hz might have fried the screens if they are designed to accept 50Hz and I think I may have foolishly set my card this way (*because more is ALWAYS better*) BUT I'm not 100% sure and I don't know how I can check this with no screens!
:S
Would any of this affect the PMU or do you think I've blown the lot - screens and graphics card?
Any advice or guidance would be very much appreciated.
P.s. I have a macbook that I can use to hook the G5 in target mode if that helps matters...
P.p.s. I'll post my G5 spec when I find out exactly what it is.
Cheers
