What does adjusting Voltage Swing and PreEmphasis change?

Jump to solution

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?

These options can potentially help a user overcome intermittent flashing or black screen issues that sometimes occur with monitors due to a bug or firmware issue.

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...
