Comment: I have a powermac 6500 at 275mhz and
another at 250mhz. it is really picky about
monitors, will only use this old 12" apple
(the old apple monitor connector) and 14"
tandy (vga monitor with monitor adapter
cable) that are from like 1994. I cannot
use this dell 17" or my apple 17" studio
display (i tried 4 different vga adapter
cables, and works with 6100/66 and
7200/75 but not my 6500 series). how can i make my 6500 computers use
my apple studio 17" display? i tried
different adapters, monitor resolutions,
color patterns...the 17" just wont
'un-low-power-mode' and use the
monitor. the 17" monitor works, and the
6500 works...just not together please email me if you post to this

Reply: (edit)Just a thought What was the resolution setting set to on the 6500
before you plugged in the 17" monitor.
If it was set to a weird setting the new monitor may not
recognize it. Probably not enough video memory. With the old monitor try setting the resolution to "640X480" and "Thousands" of colors then shut
down the computer. Then plug in the 17" and turn it on and see if it
recognizes it. If it does test your resolution settings from the
control pannel ONLY. That way you can reset by
automatic if you change to one that doesn't work. Does that make sense. Hope so - give it a shot

Reply: (edit)The 6500 has 4 recommended
resolutions like 640x480, 800x600,
832x624, 1024x768 and i have tried every
resolution with every color scheme (256,
thousands, millions) and the apple 17"
studio display just doesnt come out of the
low power state. I even set the
resolutions and rebooted the computer,
after trying changine resolutions and
switching monitors when computer was
on. I also tried resetting the motherboard,
flashing the prom, boot from an OS 7.6.1
and 8.0 and 8.5 cd thinking i would have
better luck. I think I need to force the mac monitor to
read the video signal somehow, maybe
some kind of monitor adapter...
