So I just put my 5450 through a little testing.


desktop black and video black always match.


And get this...


YCrCb passes WTW and BTB.


Its levels are exactly as if it where a set top box, but photos games and the lot also look correct.


Holy grail of video levels achieved.


(side note the edid is all messed up and I can only get 60hz or 30i, 59.97 and 23.97 don't seem to work. my signal chain here is HTPC->Onkyo 705->Lumagen Radience->Toshiba TV).

I believe teh fractional framerates is a windows issue and showing decimal framerates. Have you tried setting the framerate to 23Hz or 59Hz? I've heard reports that that should work.

Hi Sotti,

I am also running my HTPC with a ATI 5450.


Can you please explain your actual setup?


My settings at the moment:

Pixel Format --> RGB Full

Dynamic Range(Avivo) --> 16-233

Samsung LCD set to Limited Range


About the fixed 60Hz: This also occurs on my system and can only be fixed by changing the refreshrate in windows desktop properties. Changing it with ATI Catalyst is not working. Also you must deactivate "GPU Scaling" in Catalyst!


Regards,

Peter

I think the framerate thing is an issue with the lumagen + everything else, when I remove it I get 24hz and 59hz showing up.
