The Radeon Setting show some new features for my display since the release of the first ReLive driver. Display --> Specs --> Override is a section I didn't find any information about. There are two sliders "Adjust Voltage Swing" and "Adjust PreEmphasis" I can position from 0 to 2, but what do they do? And is it recommend to change these?
I don't know for certain what "Voltage Swing" does, but after I changed it from 0 to 1 I can use a 3m Display Port cable.
FWIW, I'm using:
- 1 x AMD FirePro W7000, driver version 17.Q2.1
- 3 x Samsung U28D590 (4k)
Up until this change, I'd been unable to use anything other than a 2m Display Port cable. So thanks AMD as now my PC can sit under the desk :-) Happy days...
