I am sorry for the problems you are having but let me help you.
Based on your description, I recommend you setting in your computer the Native resolution of your tv and once you have done this, you need to check the resolution settings in the TV.
In case you do this and continue having problems, please post here you graphics report by opening the Graphics and Media Control panel> Information Center> Save.
Thanks for the response. Sorry for my delayed response.
The PC is set to the native resolution of the TV 1920x1080@60p. The TV detects the input properly as 1080P.
As for the graphics report, it looks like you're referring to the older version of the Intel Control panel, which is not included in this driver. Nor does the previous hot key combination seem to bring up the information center. The current "Intel HD Graphics Control Panel" is the white one with the Display/3D/Suppport/Video/Options squares. No information center as far as I can see.
The scaling setting just refuses to take and always reverts back to "Maintain Aspect Ratio".
Any other ideas?
