Not sure what bpc stands for but I cant change color depth either.
BPC is bits per color, it's a value that pertains to your display panel's Color Depth in bits. Most TN panels are 6 bit, most TVs 8 bit, and a lot of new monitors and some TVs are 10 bit, or even 12 bit now.
What is confusing me is CCC's Color Depth value defaults to 10 for my Panasonic TC-L32U3, which I'm fairly sure is just 8 bit. I've been trying to find a tech review source to verify that, but have come up empty.
I also know of no software tool that detects your display's color depth, or whether having CCC set to a value higher than it is causes any harm or performance issues. This may just be CCC having slight detection problems.
I've read some forum chat that was posted shortly after CCC started supporting 10 bit panels, and it indicates the values are supposed to be greyed out if your display cannot match it, so I don't know, maybe this TV is actually 10 bit. I'd be shocked as hell if it was though.
