Now on the other hand the 8 bit per pixel sampling was the standard ever since the beginning of coloring system but then as screens 'Pixel Per Inch' (PPI) started advancing as now UHD TVs and 6K googles are facts people started complaining that they see gradient colors in stepping like forms and not as flowing as they should (Like for example a sunrise may appear as several arcs of different grades of orange) hence the need to raise the bit per color to allow a richer color pallet to solve that effect and hence the introduction of 10+ bit per pixel coloring with supporting videos that wouldn't show such step like gradients which was named HDR. You are mixing few things, first of all back when the HDMI standards were primitive and bandwidth was low, a compression had to be made so signal may pass, they named types of compression standards 4:2:0 (very high), 4:2:2 (mid), 4:4:4 (no compression), so if you have a 4K HDMI cable (1.4 & 2.x) you can certainly pass through raw uncompressed signal from your device hence 'What You See Is What You Get' (WYSIWYG) and no down sampling of any sort happens, this can be achieved with ease by your set of hardware and rest assured it is happening by default unless your cable is outdated. 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.
