Hi, I've recently finished writing a tool which is suitable for communication with DDC/CI (DDC2Bi) enabled monitors (Samsung, NEC/Mitsubishi are known to support it) and allows querying monitor capabilities, reading and writing monitor controls, such as contrast, brightness, geometry, etc... I'm believe, that there is some interest on this, at least googling shows that. ;-) The reason for contributing is simple - I've spent some time on this, and do not want to just this into the wastebasket. ;-) I've tested it with Samsung SyncMaster 173T with radeonfb and Nicolas Boichat, which has independently started digging on the same thing and now working with GUI version, has tested it with Mitsubishi Diamond Pro 2060u with rivafb. Mitsubishi Diamond Pro 2060u does not support capabilities request. This program is based on info sniffed on wire, published in USB Monitor Control Class 1.0 specification for control codes available at http://www.usb.org/developers/devclass_docs/usbmon10.pdf and ACCESS.bus (tm) Specifications Version 3.0 available at http://www.semtech.com/pdf/abusv30.pdf. In fact, up to date information about DDC/CI standard (Display Data Channel Command Interface (DDC/CI) Standard (formerly DDC2Bi), Version 1) is available from VESA (http://www.vesa.org) and the summary is freely available at http://www.vesa.org/summary/sumddcci.htm Attached please find a patch against lm_sensors-2.8.7. I would like if someone will review this stuff and commit it to the CVS. I'm not in the list, so please CC me in your answers. Also, I've made a web page available at this address: http://jaffar.cs.msu.su/oleg/ddcci/ Thanks, Oleg. -------------- next part -------------- A non-text attachment was scrubbed...
