Dear Sir, I got your reference from sourceforge, ddccontrol-0.4.2 source code. I am in process of developing a monitor calibration utility for windows and Mac OS X and require your help in one of the issue coming with "NVIDIA GeForce 7300 GT Dual DVI Slot issue" The card is a multi-function device having 2 DVI slots. 1st DVI (bus) is assigned to 0x36 (i.e. 0x37 and 0x36) 2nd DVI (bus) is assigned to 0x3e (i.e. 0x3F and 0x3E) 1st DVI slot always works fine without issues, i am able to set SDA and SCL but 2nd DVI slot only WORKS WHEN both MONITORS are attached to the device!! If monitor is only attached to 2nd DVI, i am not able to set/reset SDA and SCL lines. At the same time it works great it both DVI have monitors attached. I also referred your code with mine, but didnot find any such changes. Can you please guide what can be the issue ? Why is the behaviour strange in this case ? Also, I shall be helpful if you could suggest some material to study for multi-function PCI devices.Please comment. Thanks and Regards, Rohit |
