Hi all, just successfully setup a HTPC using an Asus P5N7A-VM motherboard and following this thread.
However, I have one small query. The TV I'm using is a Sony KDL-40W4500 calibrated using settings from this thread at avforums.com. Now, there are thousands of people thoroughly satisfied with the TV, however to me it appears there are no details in blacks at all.
I tried playing with the settings, and the only way to see the detail in dark scenes is to turn the brightness waaaay up. This makes the rest of the picture look incorrect.
Now surely somebody else would notice this on those forums, but alas everyone just raves how good the picture is. Now I bet most people are using a standard bluray player...
However, I'm using XBMC to play backed-up bluray's over hdmi. Now I don't know too much about color spaces, but I do know when playing the movies on my windows pc (using the appropriate codecs) colors look fine, however blacks aren't 100% black. This is not a problem, in fact I think this is how it's meant to look. It looks as if the video's color space has been adjusted to take into account display on a monitor rather than a TV, the picture looks perfect.
Now back to the XBMC + TV setup. Dark areas of the picture are way to dark, but bright areas look fine. I was thinking whether the TV expects hdmi signals with the color space correct for a tv, but xbmc is outputting a signal with a color space correct for a monitor, and maybe the mismatch between monitor and tv is causing the color problems.
Is there any truth in what I've said? If you've read to here, I thank you, as that was far too long.
The only reason I mention this is because at the moment the picture is unbearable, but surely the 100s of people over at avforums.com don't have this problem, and I bet they are using standard bluray players.
I also remember the XBox having a black level adjustment with the VGA cable, which made a difference depending it was feeding a TV or a monitor.
Thanks for any help, James
