Windows turns off monitors and then when they turn back on several are blank

Sorry I fixed the videos. I see my other threads with the details are not visible in addition to the first post of this thread.

Please add youtube url in front of below to watch

Yes I do have a lot of monitors but isn't that the point of this?

Yes the monitors are still visible to windows. It thinks they are there and I can disable and enable them. This unfortunately does not make them work.

This only happens with the displaylink driver installed. Without it installed all monitors will go into low power state and return without issue (you can see in the videos)

Yes if I copy a window with printscreen on the blank monitor it does paste properly. I have tried switching inputs on the monitors and turning them off and on also. So the OS thinks they are there and is still rendering them. I will try disabling one of the video card monitors to keep the count at 6 with the displaylink and post the result. (In case this is a boundary case over 6 like you say.)

(is there any way to view my original post with all the info?) Maybe just remove the youtube links from the initial post?

Interesting... It looks like the OS knows the screens are there and drawing to them, but the graphics card is not sending it to the screens.

Does this happen if the DisplayLink screen is disconnected, but our software is still installed?

Does restarting the DisplayLink service recover it? What about if you replug the DP cable to the monitors?

Thanks

Wim

Yes it still happens if the displaylink is disconnected and the driver is still installed.

Unplugging the display port cable does not work either.

I will look for the displaylink service and try stopping and starting it to see if it works.

Checked and stopping and starting the displaylink service doesn't help.
