https://community.intel.com/t5/Software-Archive/Backlight-Control-using-82852-82855-chipset/m-p/899365#M10646 Hi,<BR /><BR />How can we access the chipset's backlight control or is there a way to access it? I am currently using intel chipset 82852/82855 GM graphics adapter with a digital flat panel (TFT) and i'm running on windows XP embedded. I've tried a couple of approches in trying to control the backlight. IOCTL's for brightness control does not respond also i've tried to use Display Tuner wherein it uses DDC/CI protocol so that i might be able to use this protocol but it doesn't work. <BR /><BR />Sorry if this might be a dumb question, actually i'm just a newbee... i hope someone can answer this.<BR /><BR />I really need your help guys... <BR /><BR />Thanks a lot...<BR /> Fri, 22 Aug 2008 09:13:51 GMT novice28 2008-08-22T09:13:51Z https://community.intel.com/t5/Software-Archive/Backlight-Control-using-82852-82855-chipset/m-p/899365#M10646 Hi,<BR /><BR />How can we access the chipset's backlight control or is there a way to access it?
