AutoCad hardware acceleration is disabled and locked. unable to enable it.

[kadatskyura112]

I am unable to enable hardware acceleration for my Nvidia P1000, I have the latest drivers. everything was fine until this morning.
I started up AutoCad 2021 LT, the layout was different and my hardware acceleration was locked off. I am unable to change it.
It can't detect my graphic card?
Please help, a fix now, I am unable to work!

Solutions I tried that didn't work:

Updating windows,
Updating drivers using Nvidia website.

Updating drivers given with certification by AutoDesk,

Changing Registry,
Enable Windows hardware acceleration,
Turning off and on the computer multipletimes,
Installing different version of AutoCad LT 2024, 2023, 2022.
None helped.

Under 2D Display Settings can you choose another selection?

The solution was from the following link:

How to use a previous DirectX version in AutoCAD Products (autodesk.com)

Changing the DirectX version to 9 solved the issue.

Thank you for your time.

I got to note that in Windows 10 the navigation to the solution is different, because of the different layout.

At the end, the issue got solved.

Thank you for the support.
