I have a G4 AGP Mac running 10.4.11 with a 1 GHz processor and an ATI Radeon 9000 Mac Edition card. A ViewSonic P815 is connected via the DVI port on the 9000 card through a DVI to VGA adapter. Recently the red disappeared.
The 9000 drives an ACER H236HL with good color. The Acer connects with a DVI plug.
I can run the ViewSonic off an HP Desktop out of the VGA port on the HP. And the ViewSonic displays the correct colors.
Therefore, I have to believe that it is the DVI to VGA adapter (which is a rather cheap adapter) that has failed.
If that is the case, then a DVI plug and cable going to the 5 ports on the back of the ViewSonic, RGB plus horizontal and vertical hold, might just be the ticket.
Anyone know where I could get such a cable?
Thanks,
