I noticed that my nvidia GPUs have the simple "dynamic range" video setting to force true 8bit, 0-255 color space. I want my blacks in video to be true black and not merely dark gray. How can I do the same with my ATI 4850 card?

I'm using the latest driver available for my GPU - 12.6 for windows 7 x64 sp1. I'm playing videos through “BS player” using the default "EVR- enhanced video renderer" mode - like I do on all my machines. Black edges where there is no video are true black, while video black is merely darkly gray - on my ATI card.

As you know its these simple things that make or brake a GPU. Not everything is in raw speed. I'd hate to be force to use nvidia GPUs just because I cant reproduce good video colors on ATI.

I dislike black being portrayed by dark gray. The only similar option in CCC "enable dynamic contrast" makes the dark gray even whiter doing the exact opposite of what I want.

Thank you.

Yes! Exactly that. What Voodoo must I do do, to get that? This is what I have now with ati drivers 12.6 for win 7 64(latest available for hd 4850):

Looking at the names of the windows you and me posted, I'm noticing the distinctive difference.

Your windows bears the name of "AMD VISION Engine Control Center"
whereas mine uses "Catalyst Control Center"

While I applaud AMD for adding per app 3d settings and unified gamma settings for 2d, 3d and video (features I was overjoyed to find that nvidia has had for quite some time)- I'm already a little disapointed that AMD chose to leave my GPU out of updates. If in the meantime they added full video controls, but are not sharing them with my card... I would be even more so.

Nvidia still supports my old 8800gt with the latest drivers and I could set per app 3d settings, unified 2d/3d/video gamma AND video reproduction settings from day one. 4 years after I got my 4850, I finally have some of the settings nvidia supported for ages, but AMD chose not refine them any further. I just hope that the missing settings is an easily fixable glitch or that AMD adds them to drivers ASAP. Its the only decent thing to do for all their consumers... and its such a basic setting too..
