Output Color Depth 8 Vs 10

By | 13/10/2022

When continued to a 30-fleck capable monitor on Quadro GPU with driver version 430.39 and Windows 10 RS4 onwards, option would be populated for enabling 30-bit back up in NVCPL. User must select desktop colour depth SDR xxx-bit colour along with 10/12 output bpc as shown in epitome beneath:

For GeForce this support has started from NVIDA studio commuter 431.70 or higher version.

To enable 30 bit on GeForce which don’t take dedicated UI for desktop color depth, user has to select deep color in NVCPL and commuter would switch to 30 bit format.

Commencement with NVIDIA driver branch 470, we accept added support for different color format and deep color on custom resolutions. To enable desired deep color or color format, showtime create custom resolution. Annotation that custom resolution is created with RGB 8bpc by default. In one case requested custom resolution is created, go to apply settings on modify resolution folio and select desired color format/depth as shown below:

Q:
I have ten/12 scrap brandish/ TV merely I am not able to select 10/12 bpc in output colour depth drop downwards even afterwards selecting use NVIDIA settings on change resolution page.

A:
10/12 bpc need more bandwidth compared to default 8bpc, and so in that location would be cases where we are out of bandwidth to populate 10/12 bpc on NVIDIA command panel. I typical case is using HDMI ii.0 HDR TV which are capable of 10/12bpc but due to Bandwidth limitation of HDMI ii.0 higher color depths are not possible with4k@60hz. To accommodate such cases you can try lowering refresh rate or lowering resolution to get those options.

Q:
I have HDMI TV connected, I have lowered the resolution only cannot see 10bpc even though 12 bpc is available.

A:
10bpc over HDMI can be selected on NVIDIA Ampere GPUs. Older NVIDIA GPUs practice not support 10bpc over HDMI however you can use 12 bpc to enable thirty-bit colour.

Q: How can I benefit from “SDR (30 bit color)” choice on Quadro or enable ten bpc output on GeForce?

A: It allows you lot to use 10 bit (1024 color levels per aqueduct) color values instead of standard 8 bit (255 color levels per channels) in some creator applications, for example Adobe Photoshop, that support ten bit colors rendering to brandish. 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. This is especially important when you work with wide gamut colors (Adobe RGB, DCI-P3) where 8 scrap banding would be more than pronounced. Of import note : for this feature to work the whole display path, starting from the awarding’s display rendering/output, the Windows OS desktop composition (DWM) and GPU output should all support and exist configured for 10 fleck (or more) processing, if any link in this concatenation doesn’t support 10 bit (for example near Windows applications and SDR games display in viii bit) you wouldn’t encounter whatsoever benfit.

Q: What happens nether the hood when I enable “SDR (30 scrap color)” option on Quadro or enable 10 bpc output on GeForce?

A: Two things – by default Windows OS uses viii scrap desktop limerick (DWM) for SDR output (it uses FP16 composition for HDR output), the Nvidia driver/GPU volition commencement composing 10 bit applications windows using 10 flake (or higher) precision independently of DWM, while the rest 8 fleck windows, which is the instance for Windows desktop and most Windows app, volition exist composed by OS (DWM) using 8 bit. We will also change colour output by the GPU from 8 bit to ten or 12 $.25. This allows u.s. to pass all 1024 colour levels per channels from the application to the 10+ bpc supporting display without losing the precision.

Q: Should I always enable 10 bpc output on GeForce or “SDR (30 bit color)” on Quadro, when available?

A: No. Unless you lot use specific SDR applications that were designed to display colors in x bit (for example Adobe Photoshop), you wouldn’t see any benefit/deviation : if y’all outset with 8 bit application, which are absolute majority of applications on Windows, the 10 bit desktop limerick and x fleck output wouldn’t help, you are already express by viii bit by the app. Having ten bit output in these scenarios tin can actually lead to compatibility issues with some applications and slightly increase arrangement’s power draw.

Q: Exercise “SDR (thirty bit color)” option on Quadro or x bpc output on GeForce piece of work in HDR output.

A: No , there is no need for that, these pick were specifically designed to supported x chip workflows on legacy Windows OS (starting from Windows 7) which just supported 8 bit desktop limerick, the Bone could support 10 fleck workflow only in fullscreen exclusive fashion there. Starting from Windows ten Redstone 2 Microsoft has introduced the OS support for HDR, where FP16 desktop limerick is used, eliminating 8 bit precision clogging. Note, however, that non all HDR displays can render colors sufficiently accurately for professional scenarios while being in HDR style, yous could meet that colors are done out and contrast is wrong.
