when using Multi Picture Object, flicering observed.

Hi All,
I need your help to solve the flickering issues when connecting to 3
monitors.

I played a movie clip , when i start using windows + P key to have PC
screen only , duplicate, extend and second screen only. I see the
flickering is observed in my third monitor.

My driver sequence is good and no memory leakage observed through windbg.

Request for your help …

Regards,

Kumon

What, exactly, do you mean by “flickering”? Do you mean the movie plays
badly, with hesitations? Do you mean the movie alternates frames with a
black image? Or do you mean the whole monitor image blinks?

Playing a movie while switching screens is a high-stress operation.
Playing a movie requires access to advanced graphics card features, and
those features are often not available on secondary screens, requiring
the graphics chip to fall back to simulations.

I assume that you are developing a driver for the video card that is powering these displays? If so, there are many additional details that any of us need in order for any of our advise to be helpful.

You could start with a more detailed description of the observed behaviour and then some details about the card itself (bus at least) and the data to be rendered (frame rate etc.)

Hi,

Flickering means :

I could see the movie alternates frames with a black image

yes developing 3D graphics Card , for which my Driver sequence are good.

It happens specifically to 4K panel.

You could start with a more detailed description of the observed behaviour
and then some details about the card itself (bus at least) and the data to
be rendered (frame rate etc.)

Hi,
I have 3d graphics card which is in developing state and i observed these
flickering during playing a move clip .

Not sure the card specification or the data .

Regards,
kumon
