Hi,

subramanyam> How we can access the EDID of the EDID compatible monitors.
You have two way: DDC1 and DDC2. The method is different between them. DDC2 uses I2C. If you do
DDC1, you supply a DDC Read function. But there is no need in the DDC2 case.
if (pXdriver->I2C) {
xf86SetDDCproperties(pScrn, xf86PrintEDID(xf86DoEDID_DDC2(pScrn->scrnIndex, pXdriver->I2C)));
}
look at Xserver/hw/xfree86/ddc...
