Cable pins can be bent too causing intermittent contact. I agree, the adapter (or cable) seems a likely culprit. It seems like a DVI/DVI cable onto a DVI display would be optimal, but if the display only has VGA, I guess you're stuck with an adapter and a VGA cable. Also worth trying an adc/vga adapter if you can get one ADC/VGA are rare and expensive. Better to buy a new video card or display instead. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

G5 monitor fails to fire
My DP G5 running OSX 4.11 fails to wake up the monitor on start up. Monitor at the moment is a Dell flat panel but it was the same with my old Apple studio monitor. G5 chimes happily but monitor's amber light stays amber and fails to go green. I use a DVI/VGA connector, and linking my G4 powerbook to the monitor fires it up each time so the monitor is fine. Disconnecting all USBs and pulling power cable for ten minutes improved matters but now I have to power up 3-4 times or just leave it to another day. I pulled the graphics card (ATI Radeon 9600 pro), and tested for wobbly joins, dust, anything else but drew a blank. As far as I understand it the G5 is not producing a sufficient charge to wake the monitor from power save mode. Is there a specific component on the card that may be at fault, should I get a new card or could there be another explanation? regards AG -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Try a different interface.

Re: G5 monitor fails to fire
Yes, Kris Just to make it clear, taking into account your remarks. The monitor will eventually fire up - might take two, three, four G5 power-ups, might have to leave it for hours and just sometimes it might come on immediately.
