Hi dtuxi!
I've followed your guide but I think there is no change. Blacks are greys and a picture is washed out in movies.
The display: Samsung 40A656 TV, the modified driver (inf) is installed.
Graphics driver: 15.33.0 beta (latest whql driver has artifacts whit XBMC)
This driver has Metro UI, I found Limited/Full Output in Video section but nothing changed with this.
The Windows desktop looks OK but with DXVA playback blacks are gone.
What's wrong? (except that drivers have serious problems just like this)
