Windows 7: Calibrating Brightness, different in media center than control panel

02 Dec 2010   #1

Calibrating Brightness, different in media center than control panel

I have a htpc using a Radeon 4650HD video card. Have been noticing a lot of blotchy-ness and grainyness in the dark scenes of the shows I have recorded.
So I have been playing around with different calibration settings to see if I can narrow it down.

When doing brightness calibration through Windows media center you get a guy in a black suit with a black shirt who has a black X to his left.
I noticed that you can also calibrate your brightness outside of WMC by using the calibration found in the control panel. This gives you the same guy with the black suit and the black X.

Here is what I noticed.
I can adjust my brightness via the control panel calibration picture and it looks great, but when I bring up the same picture in the media center brightness calibration it is way too bright.
So, it appears that WMC isn't using the same brightness contrast controls as Windows seems to be.
I found in the CCC a checkbox that says use application settings.
I have unchecked that and been playing around with customizing the brightness/contrast via the CCC, haven't found a setting I am real happy with yet.

Can anyone tell me if they have ran across a similar issue? Just wondering if I am looking in the right spot?
I have updated to the latest ATI drivers and my dark scenes still look crappy.
I can adjust brightness to where it should be and still get that blotchyness.
Is there still an ongoing issue with ATI and Media Center video corruption?
I thought they had fixed that. Maybe not.
Any insight or thoughts appreciated.
