Which VC are you using ? AMD or Nvidia ?
If AMD : you need a DVI-HDMI cable to get 4:4:4(and the appropriate format in CCC).
If Nvidia : DVI-HDMI cable could, or could not get you 4:4:4(VC related), you may have to apply "EDID override fix", here :http://www.avsforum.com/avs-vb/showp...postcount=1375
Works for HDMI-HDMI as well(Nvidia only)
I would also recommend to start with the "Cinema" mode, it's the most accurate as far as i can tell. TV needs to "settle down" anyway, before any serious adjustments or calibration.
My settings :
Picture mode - Cinema(input labeled as "PC")
Backlight - whatever you want.
Contrast - 90
Brightness - 53
Sharpness - 37
Color - 50
Tint - 0
Color Temp. - W40
"Color Temp. - W40" may seem "too warm" or "yellow", but you just need a few days to get accustomed. Everything looks so natural for me, i can find nothing in need of improvement, besides black level.
On the other hand, our TVs could be very different due to many factors, so feel free to play with settings
P.S Yes, when you label an input as "PC", there's too much sharpness, thus "Sharpness" is so low for me(37), but it looks perfect
