Latest update - MFD are flickering on second monitor

[Andy t]

After the latest DCS update was installed, the MFD's on my second monitor are flickering and moving the cursor on an MFD on the exported monitor is laggy. I didn't change any video settings. I would appreciate any suggestions.

I am using Samsung Q80T as main monitor, setup for fixed refresh. Sceptre 20" is my secondary monitor. I set the secondary monitor refresh at 60HZ.

I would appreciate any suggestions.

Here is the lua file:

}

     width = 1600 / 3 - 120;

Set Vertical Sync to Off in nVidia control panel

 

I read another post that suggested resetting DCS specific application settings in Nvidia control panel. After doing the reset and troubleshooting, it appears the issue is linked to the Vertical Sync setting. I have to set it to Off to avoid flickering.
