Black screen flickering

I just setup my machine using a 1080p monitor, just switched to an ultrawide 3440x1440 monitor and my monitor just intermittently turns off for a couple of seconds then comes back.
Is there any fix for this? My purchase is dependent on this being fixed. I need it to work perfectly.

 

Here is my current hardware.

 

Hi JoseC8. Please refer this article to reinstall Parallels Tools and check if it helps.

 

Already did, but got the same result... Any chance I can set it to use the internal gpu in my processor?

 

Please refer the troubleshooting steps from this article and check if it works.

 

Not a good fix, since I dont have a dual monitor set up.

 

1. Shut down the virtual machine by selecting Actions (from Mac menu bar) -> Shut down.
2. Open the virtual machine configuration > switch to the Hardware tab > select the Graphics option in the left pane.
3. In the right pane, increase the video memory to 1GB.
4. Select Advanced and set to DirectX9 and check for the issue.

 

Tried that to no avail, any other approach on this?
