(It wont let me post it without the dashes around it)
I cannot seem to get to forums.amd.com, and this websites search as well as Google's are not helpful at the moment.
The thread was titled "AMD Support and Game Forums - 14.6 drivers causing issues with HDTV as monitor"
I needed the thread any time I updated my video drivers, as any AMD drivers past 14.4 were making certain people's tvs fuzzy/blurry despite all changes in catalyst control manager. IIRC, it was people who are using a GPU with only DVI output going to a tv with only HDMI inputs. At some point in the thread someone figured out how to do something with an EDID override, creating a .inf file that would allow any driver past 14.4.
If anyone can find the thread, or maybe understands EDID better, please let me know. I updated to windows 10, so my old monitor.inf file is not accepted when I manually try to use it as my video driver.
