Since 16.7.3 with a with RX480 + 3dm display port to hdmi 2.0 adapter:
- I have no pixel mapping settings in advanced. Unable to change to limited rgb.
- dolby hd \ dts hd bitsream with display port Normal dolby & dts 5.1 works fine. The hd audio tracks do work if I turn off bitsream & dowmix to normal 5.1
It all works fine with the HDMI cable. I did not have this problem prior to the update however the the dolby & dts bitsreams did drop out sometimes with the disply port only.
