I was running an AMD HD6970 miniDP to HDMI adapter to a Samsung UN6950 TV at 1920x1080p 120fps with CVT timings and it was working great. I "upgraded" to an R9 380X yesterday and haven't been able to get that same resolution working, on either of the HDMI1.4 or DP1.2 outputs from the card to either of the HDMI1.4 or HDMI2.0 inputs on the TV.

I don't know how you got 1920x1080 @ 120 Hz with CVT timing on the 6970 because that exceeds the capability of the 6970. TVs usually want CTA-861 timing, which "Automatic (HDTV)" will provide, and that will set the pixel clock to 297 MHz. If you want to try CVT, the Pixel Clock Patcher is supposed to get around any known 297 MHz limits. It's more likely to work with the HDMI port than with DP-HDMI.
