From the link: http://en.wikipedia.org/wiki/Extended_display_identification_data The EDID is often stored in the monitor in a memory device called a serial PROM (programmable read-only memory) or EEPROM (electrically erasable PROM) and is accessible via the IC bus at address 0x50.[1] The EDID PROM can often be read by the host PC even if the display itself is turned off.How can I read that information?

Answer to my own Question: [:)]i2cdetect -l    : To enlist the existing i2c adapterecho Y | i2cdump $i 0x50    : Where  i is the device id of each /dev/i2c-*The above command will print the Raw-EDID for the given I2C-Adapter.Now custom C ( or any ) programming language can be used to parse the information to give the neat description of the underlying device.[ Though I used the i2c-tools, still It will be far better to use the low-level assembly programming to read the EEPROM values. ]
