10 bits Color Output

Enable 10 Bit support for the Standard Output Configure a standard output. This is the one to use for displaying output on a second monitor Read More

Nvidia

Set your Desktop color depth as 30 bits and the Output color depth as 10 it. like below
Then in Smode you can change the color Depth bits to 10 and the alpha Depth bits to 2

AMD

Enable the 10 bit pixel format support in the AMD Advanced Setting.
Then in Smode you can change the color Depth bits to 10 and the alpha Depth bits to 2

Verify the Setting

To test your setup you can download this image: 10_bits_test_image.tif
Create a new compo, set its pixel type to 10 bits or more, and enable your output
there is not 10 bits in the Smode Viewport, it's only on the output
with this tiff image, you can see that it's separated in half, the top is an 8 bits gradient so you will always see banding, and the bottom is a 10-bits gradient so you should see less banding.

In a project

when you are in a project make sure that your project setting are at 10 bits or more

Test GPU compatibility

for checking the 10 bits compatibility of your GPU you can run the visualinfo.exe app that will output a txt file with all supported pixel format Visual-Info.zip
One you have run the app you can open the .txt and look for the wp line to see the color bits depth ( in the example below it 8 )
so if you scroll into the file and stay in the wp you will see if your GPU support 10 bits or not
Here after ID 129 I can see the different 10 bits support that confirm that I can use 10 bit color depth in Smode
