    Intel HD Graphics 4600 + 10-bit Color

    rushm3

      I just picked up a new monitor that supports 10-bit color. Does anyone know if the Intel 4600 integrated graphics board supports 10-bit color? Intel support chat was unable to help.

          Check out:

          30bit graphics support in Intel HD 4600 graphics

          4th generation Core graphics : no deep color ?

          Looks like there is a lot of confusion.

           

          Anyway the generic graphics drivers don't support 10bit.

          I remember to have seen a custom Skylake driver for Microsoft Surface though.

           

           

          ;--igfx_Gamma_Settings--

          ;--Custom CSC Matrix intialized with Identity 3x3 matrix in float format--

          HKR,, CustomCSCMatrix, %REG_BINARY%, 00

          ;Selection of 10bit Gamma and 8bit Gamma 0x0A - Enables 10 bit Gamma, 0x00 - Enables 8 bit Gamma(Default)

          HKR,, NumGammaBits,                 %REG_DWORD%, 0x00

          ; Table below is set to 10BitGamma 1024 value table currently. Each value is 2 Bytes long, in little endian format with maximum value 0xFFFF

          ; This field is valid only when “NumGammaBits” == 10. Otherwise, this filed is ignored.

          ; When “NumGammaBits” == 10bit gamma, this should be populated with valid 10-bit Gamma table with 1024 entries

          HKR,, LFPGammaEncodeXBit,       %REG_BINARY%, 00

          Don't fool around in the registry, Windows failed to boot last time i tried

            Hello rushm3,

            I understand you would like to know if Intel HD Graphics 4600 supports or not 410-bit color.

            Let me apologize for any inconvenience this issue may be causing to you.

            Intel Graphics support 10-bit color since Sandy Bridge (2nd Generation).  The driver will automatically enable 10-bit when running full screen DirectX* applications that supports it on a 10-bit capable Display.

             

            Let me know if you have or not any other inquiry.

            Regards,
            Fred D.
