MP 7,1 Screen flicker

[bcomer]

I have a MP 7,1 with the 580X video card and am seeing a flicker along the top of the screen.

Single monitor Asus PA329Q feed through TB3 -> DisplayPort 4K @ 60Hz.

The machine is running the latest Catalina update.

The monitor works perfectly with my 2015 MacBook Pro running the same version.

I do notice it more when running Safari.

Anyone else seeing this?

Do you have another cable to connect this monitor to the Mac again?

Single monitor, two parallel input, running in mirror mode.

There was an old screen flickering bug on the 7950 Mac Edition card long time ago can use this work around. I wonder if the same thing still applicable.

The About this Mac dialog was listing my PA329Q as a 61 inch 4K monitor. I opened the Displays preference dialog and held down the Option key while selecting the Scaled option. This showed a Detect button that once pressed it properly detected the monitor. It is now listed as a 32 inch 4K monitor and the flicker is gone.
