Is there any Registry hack to enable richer color than that? Does my TV supports anything higher? I know it doesn't support HDR, but I don't think HDR and 10-bit or 12-bit must be enabled together! Hopefully I can enable 10-bit or 12-bit without enabling HDR. What exactly is 'Deep Color'? I just have wider than sRGB color gamut, or it means I can also have 10-bit or 12-bit per color channel? If this is the case, how do I enable it with my hardware? Apparently the Intel driver allows only the standard 32-bit color at any resolution, including 1920x1080. Not from Windows Settings, not from Intel Graphics Properties.

Windows still reports I have 8-bit per color channel and I found no way to enable 10-bit or 12-bit per color channel. I also changed the output from RGB to YCbCr. I connected the laptop to the TV with HDMI cable at HDMI1. I have a tablet PC (tablet/laptop combo) Fujitsu Stylistic Q702 which has Intel HD 4000 graphics card. While looking at the Picture Settings in my LG UHD TV, I found that HDMI1 supports Deep Color 4:4:4 in YCbCr, so I enabled it. I'm a bit confused and I need someone to clarify some features for me.
