How to enable 10bit color mode?

[PaoloM71]

I bought an hp envy 32 with nvidia RTX 2070 video card. When windows starts the system however uses the integrated intel graphics and 8bit srgb color mode. How can I always use only the nvidia graphics card and set 10-bit color deep?

@PaoloM71 -- when Windows is running, hold-down the "Windows" key (bottom-left of your keyboard) and tap the "P" key.  Does it show that you have two display devices, or just one?

It is possible that the NVIDIA card is not fully "seated" into its slot, and thus is not recognized by the motherboard.

It is possible that the NVIDIA card has "failed", and is not detected.

You may have a motherboard that does NOT disable the onboard video, when the add-in NVIDIA card is detected, i.e. , a "dual-monitor" setup.

Is the "data" cable from the monitor connected to the onboard video-port, or to a video-port on the NVIDIA?

Hi. Thanks for your help.

It is as if I could choose what to do with the second monitor, but no option that makes use of it is really active. In fact the system detects only one monitor and the presence of the nvidia video card which I can regularly assign to applications such as photoshop. I begin to suspect that the monitor is physically connected to the integrated graphics card instead of the nvidia card. Unfortunately it is an all in one and it doesn't seem easy to open it to verify.

Edit:

I found a video explaining how to replace the various components. The video card does not physically have video outputs, it is simply plugged into a motherboard slot

Interesting. How does the output from the video-card reach the monitor? Wirelessly -- although that would be strange.

The presence of an external video-out port implies that the computer will use that port, when a monitor is attached.

As previously recommended, hold-down the "Windows" key (bottom-left of your keyboard) and tap the "P" key.

Release both keys.

Do you see options to "duplicate" or to "extend" the desktop onto the external monitor?

Close or minimize all the apps that are showing on your "wallpaper". 

Click with the right-side mouse-button anywhere on the wallpaper.

Choose either "display resolution" or "personalize".

One of the windows should give you the option to choose 24-bit or 32-bit colour.
