3D Graphics, Unknown DirectX error

[cahozhang]

Help me take a look at the Intel A40 graphics card，10.2 1010，Without inserting a display device，The following ZIP log，3D Graphics, Unknown DirectX error，You can find it by default if you change to another graphics card.

Monitor 1:

1024x768x32 60Hz 96 DPI (Primary monitor)

Weirdly enough, it can't be found without a monitor connected. Monitor 1: 1024x768x32 60Hz 96 DPI (Primary monitor, it needs to be connected to the monitor to find Monitor 1: 1920x1080x32 50Hz 96 DPI (Primary monitor)

The 3D graphics test can't be run on a video card that has no monitor connection.

Very likely the problem is with the Intel ARC video card device drivers. Intel has had a lot of problems with these and the early releases had a lot of bugs and performance issues.

Hi
David
Thanks. I would like to ask if other graphics cards are not connected to a monitor, they will default to Monitor 1: 1024x768x32 60Hz 96 DPI (Primary monitor)。Where did you get it from?

Hi! David:

I wonder if it Is mandatory for a display driver to at least offer a virtual monitor if there is no physical monitor attached. It seems there are other display adapters that also refuse to report a monitor if no physical monitor is attached.

We aren't aware of any fake / virtual monitors being created. The reported information about which monitors are connected to which cards should be accurate.
