Evening guys,
System specs below, I have dual Vega 64's running in crossfire with a MSI MPG27QC. When running a single card, Freesync works absolutely fine, however in crossfire I am often getting a black screen which swaps to a no DP input detected error and the display going to standby shortly after.
Things I have tried,
- Rolling back AMD drivers (tried versions over last six months)
- DDU uninstall each time
- Uninstall monitor driver
- Fresh OS install
- Different DP input
- Different DP cable
- Removed any OC
Eventually it'll work in full screen for a game, but next time you shut down and restart it does it again, Currently on 19.1.1
Not sure if there is anything else I can try, if I disable crossfire in Radeon Settings, it works fine, enable it, it doesn't
