This is especially important when you work with wide gamut colors (Adobe RGB, DCI-P3) where 8 bit banding would be more pronounced. Having 1024 color levels per channel produces visually smooth gradients and tonal variations, as compared to banding clearly visible with 8 bit (256 color levels per channel) output. Q: How can I benefit from "SDR (30 bit color)" option on Quadro or enable 10 bpc output on GeForce?Ī: It allows you to use 10 bit (1024 color levels per channel) color values instead of standard 8 bit (255 color levels per channels) in some creator applications, for example Adobe Photoshop, that support 10 bit colors rendering to display.
Older NVIDIA GPUs do not support 10bpc over HDMI however you can use 12 bpc to enable 30-bit color. Q: I have HDMI TV connected, I have lowered the resolution but cannot see 10bpc even though 12 bpc is available.Ī: 10bpc over HDMI can be selected on NVIDIA Ampere GPUs. One typical case is using HDMI 2.0 HDR TV which are capable of 10/12bpc but due to Bandwidth limitation of HDMI 2.0 higher color depths are not possible To accommodate such cases you can try lowering refresh rate or lowering resolution to get those options. Q: I have 10/12 bit display/ TV but I am not able to select 10/12 bpc in output color depth drop down even after selecting use NVIDIA settings on change resolution page.Ī: 10/12 bpc need more bandwidth compared to default 8bpc, so there would be cases where we are out of bandwidth to populate 10/12 bpc on NVIDIA control panel. Once requested custom resolution is created, go to apply settings on change resolution page and select desired color format/depth as shown below: Note that custom resolution is created with RGB 8bpc by default. To enable desired deep color or color format, first create custom resolution.
To enable 30 bit on GeForce which don’t have dedicated UI for desktop color depth, user has to select deep color in NVCPL and driver would switch to 30 bit format.īeginning with NVIDIA driver branch 470, we have added support for different color format and deep color on custom resolutions. User must select desktop color depth SDR 30-bit color along with 10/12 output bpc as shown in image below:įor GeForce this support has started from NVIDA studio driver 431.70 or higher version. When connected to a 30-bit capable monitor on Quadro GPU with driver version 430.39 and Windows 10 RS4 onwards, option would be populated for enabling 30-bit support in NVCPL.
